[SPARK-33287][SS][UI] Expose state custom metrics information on SS UI
### What changes were proposed in this pull request? Structured Streaming UI is not containing state custom metrics information. In this PR I've added it. ### Why are the changes needed? Missing state custom metrics information. ### Does this PR introduce _any_ user-facing change? Additional UI elements appear. ### How was this patch tested? Existing unit tests + manual test. ``` #Compile Spark echo "spark.sql.streaming.ui.enabledCustomMetricList stateOnCurrentVersionSizeBytes" >> conf/spark-defaults.conf sbin/start-master.sh sbin/start-worker.sh spark://gsomogyi-MBP16:7077 ./bin/spark-submit --master spark://gsomogyi-MBP16:7077 --deploy-mode client --class com.spark.Main ../spark-test/target/spark-test-1.0-SNAPSHOT-jar-with-dependencies.jar ``` <img width="1119" alt="Screenshot 2020-11-18 at 12 45 36" src="https://user-images.githubusercontent.com/18561820/99527506-2f979680-299d-11eb-9187-4ae7fbd2596a.png"> Closes #30336 from gaborgsomogyi/SPARK-33287.

[SPARK-33457][PYTHON] Adjust mypy configuration
### What changes were proposed in this pull request? This pull request: - Adds following flags to the main mypy configuration: - [`strict_optional`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-strict_optional) - [`no_implicit_optional`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-no_implicit_optional) - [`disallow_untyped_defs`](https://mypy.readthedocs.io/en/stable/config_file.html#confval-disallow_untyped_calls) These flags are enabled only for public API and disabled for tests and internal modules. Additionally, these PR fixes missing annotations. ### Why are the changes needed? Primary reason to propose this changes is to use standard configuration as used by typeshed project. This will allow us to be more strict, especially when interacting with JVM code. See for example #29122 (review) Additionally, it will allow us to detect cases where annotations have unintentionally omitted. ### Does this PR introduce _any_ user-facing change? Annotations only. ### How was this patch tested? `dev/lint-python`. Closes #30382 from zero323/SPARK-33457.

[SPARK-33494][SQL][AQE] Do not use local shuffle reader for repartition
### What changes were proposed in this pull request? This PR updates `ShuffleExchangeExec` to carry more information about how much we can change the partitioning. For `repartition(col)`, we should preserve the user-specified partitioning and don't apply the AQE local shuffle reader. ### Why are the changes needed? Similar to `repartition(number, col)`, we should respect the user-specified partitioning. ### Does this PR introduce _any_ user-facing change?

[SPARK-33543][SQL] Migrate SHOW COLUMNS command to use UnresolvedTabl…
…eOrView to resolve the identifier ### What changes were proposed in this pull request? This PR proposes to migrate `SHOW COLUMNS` to use `UnresolvedTableOrView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing). Note that `SHOW COLUMNS` is not yet supported for v2 tables. ### Why are the changes needed? To use `UnresolvedTableOrView` for table/view resolution. Note that `ShowColumnsCommand` internally resolves to a temp view first, so there is no resolution behavior change with this PR. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Updated existing tests. Closes #30490 from imback82/show_columns. Authored-by: Terry Kim <yuminkim@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com>

[SPARK-33224][SS][WEBUI] Add watermark gap information into SS UI page
### What changes were proposed in this pull request? This PR proposes to add the watermark gap information in SS UI page. Please refer below screenshots to see what we'd like to show in UI. ![Screen Shot 2020-11-19 at 6 56 38 PM](https://user-images.githubusercontent.com/1317309/99669306-3532d080-2ab2-11eb-9a93-03d2c6a54948.png) Please note that this PR doesn't plot the watermark value - knowing the gap between actual wall clock and watermark looks more useful than the absolute value. ### Why are the changes needed? Watermark is the one of major metrics the end users need to track for stateful queries. Watermark defines "when" the output will be emitted for append mode, hence knowing how much gap between wall clock and watermark (input data) is very helpful to make expectation of the output. ### Does this PR introduce _any_ user-facing change? Yes, SS UI query page will contain the watermark gap information. ### How was this patch tested? Basic UT added. Manually tested with two queries: > simple case You'll see consistent watermark gap with (15 seconds + a) = 10 seconds are from delay in watermark definition, 5 seconds are trigger interval. ``` import org.apache.spark.sql.streaming.Trigger spark.conf.set("spark.sql.shuffle.partitions", "10") val query = spark .readStream .format("rate") .option("rowsPerSecond", 1000) .option("rampUpTime", "10s") .load() .selectExpr("timestamp", "mod(value, 100) as mod", "value") .withWatermark("timestamp", "10 seconds") .groupBy(window($"timestamp", "1 minute", "10 seconds"), $"mod") .agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value")) .writeStream .format("console") .trigger(Trigger.ProcessingTime("5 seconds")) .outputMode("append") .start() query.awaitTermination() ``` ![Screen Shot 2020-11-19 at 7 00 21 PM](https://user-images.githubusercontent.com/1317309/99669049-dbcaa180-2ab1-11eb-8789-10b35857dda0.png) > complicated case This randomizes the timestamp, hence producing random watermark gap. This won't be smaller than 15 seconds as I described earlier. ``` import org.apache.spark.sql.streaming.Trigger spark.conf.set("spark.sql.shuffle.partitions", "10") val query = spark .readStream .format("rate") .option("rowsPerSecond", 1000) .option("rampUpTime", "10s") .load() .selectExpr("*", "CAST(CAST(timestamp AS BIGINT) - CAST((RAND() * 100000) AS BIGINT) AS TIMESTAMP) AS tsMod") .selectExpr("tsMod", "mod(value, 100) as mod", "value") .withWatermark("tsMod", "10 seconds") .groupBy(window($"tsMod", "1 minute", "10 seconds"), $"mod") .agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value")) .writeStream .format("console") .trigger(Trigger.ProcessingTime("5 seconds")) .outputMode("append") .start() query.awaitTermination() ``` ![Screen Shot 2020-11-19 at 6 56 47 PM](https://user-images.githubusercontent.com/1317309/99669029-d5d4c080-2ab1-11eb-9c63-d05b3e1ab391.png) Closes #30427 from HeartSaVioR/SPARK-33224.

[SPARK-33549][SQL] Remove configuration spark.sql.legacy.allowCastNum…
…ericToTimestamp ### What changes were proposed in this pull request? Remove SQL configuration spark.sql.legacy.allowCastNumericToTimestamp ### Why are the changes needed? In the current master branch, there is a new configuration `spark.sql.legacy.allowCastNumericToTimestamp` which controls whether to cast Numeric types to Timestamp or not. The default value is true. After #30260, the type conversion between Timestamp type and Numeric type is disallowed in ANSI mode. So, we don't need to a separate configuration `spark.sql.legacy.allowCastNumericToTimestamp` for disallowing the conversion. Users just need to set `spark.sql.ansi.enabled` for the behavior. As the configuration is not in any released yet, we should remove the configuration to make things simpler. ### Does this PR introduce _any_ user-facing change? No, since the configuration is not released yet. ### How was this patch tested? Existing test cases Closes #30493 from gengliangwang/LEGACY_ALLOW_CAST_NUMERIC_TO_TIMESTAMP.

[SPARK-33509][SQL] List partition by names from a V2 table which supp…
…orts partition management ### What changes were proposed in this pull request? 1. Add new method `listPartitionByNames` to the `SupportsPartitionManagement` interface. It allows to list partitions by partition names and their values. 2. Implement new method in `InMemoryPartitionTable` which is used in DSv2 tests. ### Why are the changes needed? Currently, the `SupportsPartitionManagement` interface exposes only `listPartitionIdentifiers` which allows to list partitions by partition values. And it requires to specify all values for partition schema fields in the prefix. This restriction does not allow to list partitions by some of partition names (not all of them). For example, the table `tableA` is partitioned by two column `year` and `month` ``` CREATE TABLE tableA (price int, year int, month int) USING _ partitioned by (year, month) ``` and has the following partitions: ``` PARTITION(year = 2015, month = 1) PARTITION(year = 2015, month = 2) PARTITION(year = 2016, month = 2) PARTITION(year = 2016, month = 3) ``` If we want to list all partitions with `month = 2`, we have to specify `year` for **listPartitionIdentifiers()** which not always possible as we don't know all `year` values in advance. New method **listPartitionByNames()** allows to specify partition values only for `month`, and get two partitions: ``` PARTITION(year = 2015, month = 2) PARTITION(year = 2016, month = 2) ``` ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? By running the affected test suite `SupportsPartitionManagementSuite`. Closes #30452 from MaxGekk/column-names-listPartitionIdentifiers.

[SPARK-27194][SPARK-29302][SQL] Fix commit collision in dynamic parti…
…tion overwrite mode ### What changes were proposed in this pull request? When using dynamic partition overwrite, each task has its working dir under staging dir like `stagingDir/.spark-staging-{jobId}`, each task commits to `outputPath/.spark-staging-{jobId}/{partitionId}/part-{taskId}-{jobId}{ext}`. When speculation enable, multiple task attempts would be setup for one task, **they have same task id and they would commit to same file concurrently**. Due to host done or node preemption, the partly-committed files aren't cleaned up, a FileAlreadyExistsException would be raised in this situation, resulting in job failure. I don't try to change task commit process for dynamic partition overwrite, like adding attempt id to task working dir for each attempts and committing to final output dir via a new outputCommitCoordinator, here is reason: 1. `FileOutputCommitter` already has commit coordinator for each task attempts, we can leverage it rather than build a new one. 2. To say the least, we implement a coordinator solving task attempts commit conflict, suppose a severe case, application master failover, tasks with same attempt id and same task id would commit to same files, the `FileAlreadyExistsException` risk still exists In this pr, I leverage FileOutputCommitter to solve the problem: 1. when initing a write job description, set `outputPath/.spark-staging-{jobId}` as the output dir 2. each task attempt writes output to `outputPath/.spark-staging-{jobId}/_temporary/${appAttemptId}/_temporary/${taskAttemptId}/{partitionId}/part-{taskId}-{jobId}{ext}` 3. leverage `FileOutputCommitter` coordinator, write job firstly commits output to `outputPath/.spark-staging-{jobId}/{partitionId}` 4. for dynamic partition overwrite, write job finally move `outputPath/.spark-staging-{jobId}/{partitionId}` to `outputPath/{partitionId}` ### Why are the changes needed? Without this pr, dynamic partition overwrite would fail ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? added UT.

[SPARK-33540][SQL] Subexpression elimination for interpreted predicate
### What changes were proposed in this pull request? This patch proposes to support subexpression elimination for interpreted predicate. ### Why are the changes needed? Similar to interpreted projection, there are use cases when codegen predicate is not able to work, e.g. too complex schema, non-codegen expression, etc. When there are frequently occurring expressions (subexpressions) among predicate expression, the performance is quite bad as we need to re-compute same expressions. We should be able to support subexpression elimination for interpreted predicate like interpreted projection. ### Does this PR introduce _any_ user-facing change? No, this doesn't change user behavior. ### How was this patch tested? Unit test and benchmark. Closes #30497 from viirya/SPARK-33540.

[SPARK-33562][UI] Improve the style of the checkbox in executor page
### What changes were proposed in this pull request? 1. Remove the fixed width style of class `container-fluid-div`. So that the UI looks clean when the text is long. 2. Add one space between a checkbox and the text on the right side, which is consistent with the stage page. ### Why are the changes needed? The width of class `container-fluid-div` is set as 200px after #21688 . This makes the checkbox in the executor page messy. ![image](https://user-images.githubusercontent.com/1097932/100242069-3bc5ab80-2ee9-11eb-8c7d-96c221398fee.png) We should remove the width limit. ### Does this PR introduce _any_ user-facing change?

[SPARK-33551][SQL] Do not use custom shuffle reader for repartition
### What changes were proposed in this pull request? This PR fixes an AQE issue where local shuffle reader, partition coalescing, or skew join optimization can be mistakenly applied to a shuffle introduced by repartition or a regular shuffle that logically replaces a repartition shuffle. The proposed solution checks for the presence of any repartition shuffle and filters out not applicable optimization rules for the final stage in an AQE plan. ### Why are the changes needed? Without the change, the output of a repartition query may not be correct. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Added UT.

[SPARK-33566][CORE][SQL][SS][PYTHON] Make unescapedQuoteHandling opti…
…on configurable when read CSV ### What changes were proposed in this pull request? There are some differences between Spark CSV, opencsv and commons-csv, the typical case are described in SPARK-33566, When there are both unescaped quotes and unescaped qualifier in value, the results of parsing are different. The reason for the difference is Spark use `STOP_AT_DELIMITER` as default `UnescapedQuoteHandling` to build `CsvParser` and it not configurable. On the other hand, opencsv and commons-csv use the parsing mechanism similar to `STOP_AT_CLOSING_QUOTE ` by default. So this pr make `unescapedQuoteHandling` option configurable to get the same parsing result as opencsv and commons-csv. ### Why are the changes needed? Make unescapedQuoteHandling option configurable when read CSV to make parsing more flexible。 ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? - Pass the Jenkins or GitHub Action - Add a new case similar to that described in SPARK-33566 Closes #30518 from LuciferYang/SPARK-33566.

This PR proposes to improve the exception messages while `UnresolvedTableOrView` is handled based on this suggestion: #30321 (comment). Currently, when an identifier is resolved to a temp view when a table/permanent view is expected, the following exception message is displayed (e.g., for `SHOW CREATE TABLE`): ``` t is a temp view not table or permanent view. ``` After this PR, the message will be: ``` t is a temp view. 'SHOW CREATE TABLE' expects a table or permanent view. ``` Also, if an identifier is not resolved, the following exception message is currently used: ``` Table or view not found: t ``` After this PR, the message will be: ``` Table or permanent view not found for 'SHOW CREATE TABLE': t ``` or ``` Table or view not found for 'ANALYZE TABLE ...

[SPARK-28645][SQL] ParseException is thrown when the window is redefined
### What changes were proposed in this pull request? Currently in Spark one could redefine a window. For instance: `select count(*) OVER w FROM tenk1 WINDOW w AS (ORDER BY unique1), w AS (ORDER BY unique1);` The window `w` is defined two times. In PgSQL, on the other hand, a thrown will happen: `ERROR: window "w" is already defined` ### Why are the changes needed? The current implement gives the following window definitions a higher priority. But it wasn't Spark's intention and users can't know from any document of Spark. This PR fixes the bug. ### Does this PR introduce _any_ user-facing change? Yes. There is an example query output with/without this fix. ``` SELECT employee_name, salary, first_value(employee_name) OVER w highest_salary, nth_value(employee_name, 2) OVER w second_highest_salary FROM basic_pays WINDOW w AS (ORDER BY salary DESC ROWS BETWEEN UNBOUNDED PRECEDING AND 1 FOLLOWING), w AS (ORDER BY salary DESC ROWS BETWEEN UNBOUNDED PRECEDING AND 2 FOLLOWING) ORDER BY salary DESC ``` The output before this fix: ``` Larry Bott 11798 Larry Bott Gerard Bondur Gerard Bondur 11472 Larry Bott Gerard Bondur Pamela Castillo 11303 Larry Bott Gerard Bondur Barry Jones 10586 Larry Bott Gerard Bondur George Vanauf 10563 Larry Bott Gerard Bondur Loui Bondur 10449 Larry Bott Gerard Bondur Mary Patterson 9998 Larry Bott Gerard Bondur Steve Patterson 9441 Larry Bott Gerard Bondur Julie Firrelli 9181 Larry Bott Gerard Bondur Jeff Firrelli 8992 Larry Bott Gerard Bondur William Patterson 8870 Larry Bott Gerard Bondur Diane Murphy 8435 Larry Bott Gerard Bondur Leslie Jennings 8113 Larry Bott Gerard Bondur Gerard Hernandez 6949 Larry Bott Gerard Bondur Foon Yue Tseng 6660 Larry Bott Gerard Bondur Anthony Bow 6627 Larry Bott Gerard Bondur Leslie Thompson 5186 Larry Bott Gerard Bondur ``` The output after this fix: ``` struct<> -- !query output org.apache.spark.sql.catalyst.parser.ParseException The definition of window 'w' is repetitive(line 8, pos 0) ``` ### How was this patch tested?

[SPARK-33141][SQL] Capture SQL configs when creating permanent views
### What changes were proposed in this pull request? This PR makes CreateViewCommand/AlterViewAsCommand capturing runtime SQL configs and store them as view properties. These configs will be applied during the parsing and analysis phases of the view resolution. Users can set `spark.sql.legacy.useCurrentConfigsForView` to `true` to restore the behavior before. ### Why are the changes needed? This PR is a sub-task of [SPARK-33138](https://issues.apache.org/jira/browse/SPARK-33138) that proposes to unify temp view and permanent view behaviors. This PR makes permanent views mimicking the temp view behavior that "fixes" view semantic by directly storing resolved LogicalPlan. For example, if a user uses spark 2.4 to create a view that contains null values from division-by-zero expressions, she may not want that other users' queries which reference her view throw exceptions when running on spark 3.x with ansi mode on. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? added UT + existing UTs (improved) Closes #30289 from luluorta/SPARK-33141.

[SPARK-33570][SQL][TESTS] Set the proper version of gssapi plugin aut…
…omatically for MariaDBKrbIntegrationSuite ### What changes were proposed in this pull request? This PR changes mariadb_docker_entrypoint.sh to set the proper version automatically for mariadb-plugin-gssapi-server. The proper version is based on the one of mariadb-server. Also, this PR enables to use arbitrary docker image by setting the environment variable `MARIADB_CONTAINER_IMAGE_NAME`. ### Why are the changes needed? For `MariaDBKrbIntegrationSuite`, the version of `mariadb-plugin-gssapi-server` is currently set to `10.5.5` in `mariadb_docker_entrypoint.sh` but it's no longer available in the official apt repository and `MariaDBKrbIntegrationSuite` doesn't pass for now. It seems that only the most recent three versions are available for each major version and they are `10.5.6`, `10.5.7` and `10.5.8` for now. Further, the release cycle of MariaDB seems to be very rapid (1 ~ 2 months) so I don't think it's a good idea to set to an specific version for `mariadb-plugin-gssapi-server`. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Confirmed that `MariaDBKrbIntegrationSuite` passes with the following commands. ``` $ build/sbt -Pdocker-integration-tests -Phive -Phive-thriftserver package "testOnly org.apache.spark.sql.jdbc.MariaDBKrbIntegrationSuite" ``` In this case, we can see what version of `mariadb-plugin-gssapi-server` is going to be installed in the following container log message. ``` Installing mariadb-plugin-gssapi-server=1:10.5.8+maria~focal ``` Or, we can set MARIADB_CONTAINER_IMAGE_NAME for a specific version of MariaDB. ``` $ MARIADB_DOCKER_IMAGE_NAME=mariadb:10.5.6 build/sbt -Pdocker-integration-tests -Phive -Phive-thriftserver package "testOnly org.apache.spark.sql.jdbc.MariaDBKrbIntegrationSuite" ``` ``` Installing mariadb-plugin-gssapi-server=1:10.5.6+maria~focal ``` Closes #30515 from sarutak/fix-MariaDBKrbIntegrationSuite.

[SPARK-33587][CORE] Kill the executor on nested fatal errors
### What changes were proposed in this pull request? Currently we will kill the executor when hitting a fatal error. However, if the fatal error is wrapped by another exception, such as - java.util.concurrent.ExecutionException, com.google.common.util.concurrent.UncheckedExecutionException, com.google.common.util.concurrent.ExecutionError when using Guava cache or Java thread pool. - SparkException thrown from https://github.com/apache/spark/blob/cf98a761de677c733f3c33230e1c63ddb785d5c5/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/FileFormatWriter.scala#L231 or https://github.com/apache/spark/blob/cf98a761de677c733f3c33230e1c63ddb785d5c5/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/FileFormatWriter.scala#L296 We will still keep the executor running. Fatal errors are usually unrecoverable (such as OutOfMemoryError), some components may be in a broken state when hitting a fatal error and it's hard to predicate the behaviors of a broken component. Hence, it's better to detect the nested fatal error as well and kill the executor. Then we can rely on Spark's fault tolerance to recover. ### Why are the changes needed? Fatal errors are usually unrecoverable (such as OutOfMemoryError), some components may be in a broken state when hitting a fatal error and it's hard to predicate the behaviors of a broken component. Hence, it's better to detect the nested fatal error as well and kill the executor. Then we can rely on Spark's fault tolerance to recover. ### Does this PR introduce _any_ user-facing change? Yep. There is a slight internal behavior change on when to kill an executor. We will kill the executor when detecting a nested fatal error in the exception chain. `spark.executor.killOnFatalError.depth` is added to allow users to turn off this change if the slight behavior change impacts them. ### How was this patch tested? The new method `Executor.isFatalError` is tested by `spark.executor.killOnNestedFatalError`. Closes #30528 from zsxwing/SPARK-33587.

Even when `spark.sql.caseSensitive` is `false` which is the default value, v1 `SHOW TABLE EXTENDED` is case sensitive: ```sql spark-sql> CREATE TABLE tbl1 (price int, qty int, year int, month int) > USING parquet > partitioned by (year, month); spark-sql> INSERT INTO tbl1 PARTITION(year = 2015, month = 1) SELECT 1, 1; spark-sql> SHOW TABLE EXTENDED LIKE 'tbl1' PARTITION(YEAR = 2015, Month = 1); Error in query: Partition spec is invalid. The spec (YEAR, Month) must match the partition spec (year, month) defined in table '`default`.`tbl1`'; ``` ### Does this PR introduce _any_ user-facing change? Yes. After the changes, the `SHOW TABLE EXTENDED` command respects the SQL config. And for example above, it returns correct result: ```sql spark-sql> SHOW TABLE EXTENDED LIKE 'tbl1' PARTITION(YEAR = 2015, Month = 1); default tbl1 false Partition Values: [year=2015, month=1] Location: file:/Users/maximgekk/spark-warehouse/tbl1/year=2015/month=1 Serde Library: org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe InputFormat: org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat OutputFormat: org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat Storage Properties: [serialization.format=1, path=file:/Users/maximgekk/spark-warehouse/tbl1] Partition Parameters: {transient_lastDdlTime=1606595118, totalSize=623, numFiles=1} Created Time: Sat Nov 28 23:25:18 MSK 2020 Last Access: UNKNOWN Partition Statistics: 623 bytes ``` ### How was this patch tested?

[SPARK-32976][SQL] Support column list in INSERT statement
### What changes were proposed in this pull request? #### JIRA expectations ``` INSERT currently does not support named column lists. INSERT INTO <table> (col1, col2,…) VALUES( 'val1', 'val2', … ) Note, we assume the column list contains all the column names. Issue an exception if the list is not complete. The column order could be different from the column order defined in the table definition. ``` #### implemetations In this PR, we add a column list as an optional part to the `INSERT OVERWRITE/INTO` statements: ``` /** * {{{ * INSERT OVERWRITE TABLE tableIdentifier [partitionSpec [IF NOT EXISTS]]? [identifierList] ... * INSERT INTO [TABLE] tableIdentifier [partitionSpec] [identifierList] ... * }}} */ ``` The column list represents all expected columns with an explicit order that you want to insert to the target table. **Particularly**, we assume the column list contains all the column names in the current implementation, it will fail when the list is incomplete. In **Analyzer**, we add a code path to resolve the column list in the `ResolveOutputRelation` rule before it is transformed to v1 or v2 command. It will fail here if the list has any field that not belongs to the target table. Then, for v2 command, e.g. `AppendData`, we use the resolved column list and output of the target table to resolve the output of the source query `ResolveOutputRelation` rule. If the list has duplicated columns, we fail. If the list is not empty but the list size does not match the target table, we fail. If no other exceptions occur, we use the column list to map the output of the source query to the output of the target table. The column list will be set to Nil and it will not hit the rule again after it is resolved. for v1 command, those all happen in the `PreprocessTableInsertion` rule ### Why are the changes needed? new feature support ### Does this PR introduce _any_ user-facing change? yes, insert into/overwrite table support specify column list ### How was this patch tested? new tests Closes #29893 from yaooqinn/SPARK-32976.

[SPARK-33448][SQL] Support CACHE/UNCACHE TABLE commands for v2 tables
### What changes were proposed in this pull request? This PR proposes to support `CHACHE/UNCACHE TABLE` commands for v2 tables. In addtion, this PR proposes to migrate `CACHE/UNCACHE TABLE` to use `UnresolvedTableOrView` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing). ### Why are the changes needed? To support `CACHE/UNCACHE TABLE` commands for v2 tables. Note that `CACHE/UNCACHE TABLE` for v1 tables/views go through `SparkSession.table` to resolve identifier, which resolves temp views first, so there is no change in the behavior by moving to the new framework. ### Does this PR introduce _any_ user-facing change? Yes. Now the user can run `CACHE/UNCACHE TABLE` commands on v2 tables. ### How was this patch tested? Added/updated existing tests. Closes #30403 from imback82/cache_table.

[SPARK-28646][SQL] Fix bug of Count so as consistent with mainstream …
…databases ### What changes were proposed in this pull request? Currently, Spark allows calls to `count` even for non parameterless aggregate function. For example, the following query actually works: `SELECT count() FROM tenk1;` On the other hand, mainstream databases will throw an error. **Oracle** `> ORA-00909: invalid number of arguments` **PgSQL** `ERROR: count(*) must be used to call a parameterless aggregate function` **MySQL** `> 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')` ### Why are the changes needed? Fix a bug so that consistent with mainstream databases. There is an example query output with/without this fix. `SELECT count() FROM testData;` The output before this fix: `0` The output after this fix: ``` org.apache.spark.sql.AnalysisException cannot resolve 'count()' due to data type mismatch: count requires at least one argument.; line 1 pos 7 ``` ### Does this PR introduce _any_ user-facing change? Yes. If not specify parameter for `count`, will throw an error. ### How was this patch tested? Jenkins test. Closes #30541 from beliefer/SPARK-28646.

[SPARK-33480][SQL] Support char/varchar type
### What changes were proposed in this pull request? This PR adds the char/varchar type which is kind of a variant of string type: 1. Char type is fixed-length string. When comparing char type values, we need to pad the shorter one to the longer length. 2. Varchar type is string with a length limitation. To implement the char/varchar semantic, this PR: 1. Do string length check when writing to char/varchar type columns. 2. Do string padding when reading char type columns. We don't do it at the writing side to save storage space. 3. Do string padding when comparing char type column with string literal or another char type column. (string literal is fixed length so should be treated as char type as well) To simplify the implementation, this PR doesn't propagate char/varchar type info through functions/operators(e.g. `substring`). That said, a column can only be char/varchar type if it's a table column, not a derived column like `SELECT substring(col)`. To be safe, this PR doesn't add char/varchar type to the query engine(expression input check, internal row framework, codegen framework, etc.). We will replace char/varchar type by string type with metadata (`Attribute.metadata` or `StructField.metadata`) that includes the original type string before it goes into the query engine. That said, the existing code will not see char/varchar type but only string type. char/varchar type may come from several places: 1. v1 table from hive catalog. 2. v2 table from v2 catalog. 3. user-specified schema in `spark.read.schema` and `spark.readStream.schema` 4. `Column.cast` 5. schema string in places like `from_json`, pandas UDF, etc. These places use SQL parser which replaces char/varchar with string already, even before this PR. This PR covers all the above cases, implements the length check and padding feature by looking at string type with special metadata. ### Why are the changes needed? char and varchar are standard SQL types. varchar is widely used in other databases instead of string type. ### Does this PR introduce _any_ user-facing change? For hive tables: now the table insertion fails if the value exceeds char/varchar length. Previously we truncate the value silently. For other tables: 1. now char type is allowed. 2. now we have length check when inserting to varchar columns. Previously we write the value as it is. ### How was this patch tested? new tests Closes #30412 from cloud-fan/char.

[SPARK-33579][UI] Fix executor blank page behind proxy
### What changes were proposed in this pull request? Fix some "hardcoded" API urls in Web UI. More specifically, we avoid the use of `location.origin` when constructing URLs for internal API calls within the JavaScript. Instead, we use `apiRoot` global variable. ### Why are the changes needed? On one hand, it allows us to build relative URLs. On the other hand, `apiRoot` reflects the Spark property `spark.ui.proxyBase` which can be set to change the root path of the Web UI. If `spark.ui.proxyBase` is actually set, original URLs become incorrect, and we end up with an executors blank page. I encounter this bug when accessing the Web UI behind a proxy (in my case a Kubernetes Ingress). See the following link for more context: jupyterhub/jupyter-server-proxy#57 (comment) ### Does this PR introduce _any_ user-facing change? Yes, as all the changes introduced are in the JavaScript for the Web UI. ### How the changes have been tested ? I modified/debugged the JavaScript as in the commit with the help of the developer tools in Google Chrome, while accessing the Web UI of my Spark app behind my k8s ingress.

Implement V2 execution node `ShowPartitionsExec` similar to V1 `ShowPartitionsCommand`. ### Why are the changes needed? To have feature parity with Datasource V1. ### Does this PR introduce _any_ user-facing change? Yes.

[SPARK-33185][YARN][FOLLOW-ON] Leverage RM's RPC API instead of REST …
…to fetch driver log links in yarn.Client ### What changes were proposed in this pull request? This is a follow-on to PR #30096 which initially added support for printing direct links to the driver stdout/stderr logs from the application report output in `yarn.Client` using the `spark.yarn.includeDriverLogsLink` configuration. That PR made use of the ResourceManager's REST APIs to fetch the necessary information to construct the links. This PR proposes removing the dependency on the REST API, since the new logic is the only place in `yarn.Client` which makes use of this API, and instead leverages the RPC API via `YarnClient`, which brings the code in line with the rest of `yarn.Client`. ### Why are the changes needed? While the old logic worked okay when running a Spark application in a "standard" environment with full access to Kerberos credentials, it can fail when run in an environment with restricted Kerberos credentials. In our case, this environment is represented by [Azkaban](https://azkaban.github.io/), but it likely affects other job scheduling systems as well. In such an environment, the application has delegation tokens which enabled it to communicate with services such as YARN, but the RM REST API is not typically covered by such delegation tokens (note that although YARN does actually support accessing the RM REST API via a delegation token as documented [here](https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Delegation_Tokens_API), it is a new feature in alpha phase, and most deployments are likely not retrieving this token today). Besides this enhancement, leveraging the `YarnClient` APIs greatly simplifies the processing logic, such as removing all JSON parsing. ### Does this PR introduce _any_ user-facing change? Very minimal user-facing changes on top of PR #30096. Basically expands the scope of environments in which that feature will operate correctly. ### How was this patch tested? In addition to redoing the `spark-submit` testing as mentioned in PR #30096, I also tested this logic in a restricted-credentials environment (Azkaban). It succeeds where the previous logic would fail with a 401 error. Closes #30450 from xkrogen/xkrogen-SPARK-33185-driverlogs-followon.

[SPARK-33545][CORE] Support Fallback Storage during Worker decommission
### What changes were proposed in this pull request? This PR aims to support storage migration to the fallback storage like cloud storage (`S3`) during worker decommission for the corner cases where the exceptions occur or there is no live peer left. Although this PR focuses on cloud storage like `S3` which has a TTL feature in order to simplify Spark's logic, we can use alternative fallback storages like HDFS/NFS(EFS) if the user provides a clean-up mechanism. ### Why are the changes needed? Currently, storage migration is not possible when there is no available executor. For example, when there is one executor, the executor cannot perform storage migration because it has no peer. ### Does this PR introduce _any_ user-facing change? Yes. This is a new feature. ### How was this patch tested? Pass the CIs with newly added test cases. Closes #30492 from dongjoon-hyun/SPARK-33545.

[SPARK-33440][CORE] Use current timestamp with warning log in HadoopF…
…SDelegationTokenProvider when the issue date for token is not set up properly ### What changes were proposed in this pull request? This PR proposes to use current timestamp with warning log when the issue date for token is not set up properly. The next section will explain the rationalization with details. ### Why are the changes needed? Unfortunately not every implementations respect the `issue date` in `AbstractDelegationTokenIdentifier`, which Spark relies on while calculating. The default value of issue date is 0L, which is far from actual issue date, breaking logic on calculating next renewal date under some circumstance, leading to 0 interval (immediate) on rescheduling token renewal. In HadoopFSDelegationTokenProvider, Spark calculates token renewal interval as below: https://github.com/apache/spark/blob/2c64b731ae6a976b0d75a95901db849b4a0e2393/core/src/main/scala/org/apache/spark/deploy/security/HadoopFSDelegationTokenProvider.scala#L123-L134 The interval is calculated as `token.renew() - identifier.getIssueDate`, which is providing correct interval assuming both `token.renew()` and `identifier.getIssueDate` produce correct value, but it's going to be weird when `identifier.getIssueDate` provides 0L (default value), like below: ``` 20/10/13 06:34:19 INFO security.HadoopFSDelegationTokenProvider: Renewal interval is 1603175657000 for token S3ADelegationToken/IDBroker 20/10/13 06:34:19 INFO security.HadoopFSDelegationTokenProvider: Renewal interval is 86400048 for token HDFS_DELEGATION_TOKEN ``` Hopefully we pick the minimum value as safety guard (so in this case, `86400048` is being picked up), but the safety guard leads unintentional bad impact on this case. https://github.com/apache/spark/blob/2c64b731ae6a976b0d75a95901db849b4a0e2393/core/src/main/scala/org/apache/spark/deploy/security/HadoopFSDelegationTokenProvider.scala#L58-L71 Spark leverages the interval being calculated in above, "minimum" value of intervals, and blindly adds the value to token's issue date to calculates the next renewal date for the token, and picks "minimum" value again. In problematic case, the value would be `86400048` (86400048 + 0) which is quite smaller than current timestamp. https://github.com/apache/spark/blob/2c64b731ae6a976b0d75a95901db849b4a0e2393/core/src/main/scala/org/apache/spark/deploy/security/HadoopDelegationTokenManager.scala#L228-L234 The next renewal date is subtracted with current timestamp again to get the interval, and multiplexed by configured ratio to produce the final schedule interval. In problematic case, this value goes to negative. https://github.com/apache/spark/blob/2c64b731ae6a976b0d75a95901db849b4a0e2393/core/src/main/scala/org/apache/spark/deploy/security/HadoopDelegationTokenManager.scala#L180-L188 There's a safety guard to not allow negative value, but that's simply 0 meaning schedule immediately. This triggers next calculation of next renewal date to calculate the schedule interval, lead to the same behavior, hence updating delegation token immediately and continuously. As we fetch token just before the calculation happens, the actual issue date is likely slightly before, hence it's not that dangerous to use current timestamp as issue date for the token the issue date has not been set up properly. Still, it's better not to leave the token implementation as it is, so we log warn message to let end users consult with token implementer. ### Does this PR introduce _any_ user-facing change? Yes. End users won't encounter the tight loop of schedule of token renewal after the PR. In end users' perspective of reflection, there's nothing end users need to change. ### How was this patch tested? Manually tested with problematic environment. Closes #30366 from HeartSaVioR/SPARK-33440.

[SPARK-33607][SS][WEBUI] Input Rate timeline/histogram aren't rendere…
…d if built with Scala 2.13 ### What changes were proposed in this pull request? This PR fixes an issue that the histogram and timeline aren't rendered in the `Streaming Query Statistics` page if we built Spark with Scala 2.13. ![before-fix-the-issue](https://user-images.githubusercontent.com/4736016/100612855-f543d700-3356-11eb-90d9-ede57b8b3f4f.png) ![NaN_Error](https://user-images.githubusercontent.com/4736016/100612879-00970280-3357-11eb-97cf-43978bbe2d3a.png) The reason is [`maxRecordRate` can be `NaN`](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/streaming/ui/StreamingQueryStatisticsPage.scala#L371) for Scala 2.13. The `NaN` is the result of [`query.recentProgress.map(_.inputRowsPerSecond).max`](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/streaming/ui/StreamingQueryStatisticsPage.scala#L372) when the first element of `query.recentProgress.map(_.inputRowsPerSecond)` is `NaN`. Actually, the comparison logic for `Double` type was changed in Scala 2.13. scala/bug#12107 scala/scala#6410 So this issue happens as of Scala 2.13. The root cause of the `NaN` is [here](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/ProgressReporter.scala#L164). This `NaN` seems to be an initial value of `inputTimeSec` so I think `Double.PositiveInfinity` is suitable rather than `NaN` and this change can resolve this issue. ### Why are the changes needed? To make sure we can use the histogram/timeline with Scala 2.13. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? First, I built with the following commands. ``` $ /dev/change-scala-version.sh 2.13 $ build/sbt -Phive -Phive-thriftserver -Pscala-2.13 package ``` Then, ran the following query (this is brought from #30427 ). ``` import org.apache.spark.sql.streaming.Trigger val query = spark .readStream .format("rate") .option("rowsPerSecond", 1000) .option("rampUpTime", "10s") .load() .selectExpr("*", "CAST(CAST(timestamp AS BIGINT) - CAST((RAND() * 100000) AS BIGINT) AS TIMESTAMP) AS tsMod") .selectExpr("tsMod", "mod(value, 100) as mod", "value") .withWatermark("tsMod", "10 seconds") .groupBy(window($"tsMod", "1 minute", "10 seconds"), $"mod") .agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value")) .writeStream .format("console") .trigger(Trigger.ProcessingTime("5 seconds")) .outputMode("append") .start() ``` Finally, I confirmed that the timeline and histogram are rendered. ![after-fix-the-issue](https://user-images.githubusercontent.com/4736016/100612736-c9285600-3356-11eb-856d-7e53cc656c36.png) ``` Closes #30546 from sarutak/ss-nan.

[SPARK-30900][SS] FileStreamSource: Avoid reading compact metadata lo…
…g twice if the query restarts from compact batch ### What changes were proposed in this pull request? This patch addresses the case where compact metadata file is read twice in FileStreamSource during restarting query. When restarting the query, there is a case which the query starts from compaction batch, and the batch has source metadata file to read. One case is that the previous query succeeded to read from inputs, but not finalized the batch for various reasons. The patch finds the latest compaction batch when restoring from metadata log, and put entries for the batch into the file entry cache which would avoid reading compact batch file twice. FileStreamSourceLog doesn't know about offset / commit metadata in checkpoint so doesn't know which exactly batch to start from, but in practice, only couple of latest batches are candidates to be started from when restarting query. This patch leverages the fact to skip calculation if possible. ### Why are the changes needed? Spark incurs unnecessary cost on reading the compact metadata file twice on some case, which may not be ignorable when the query has been processed huge number of files so far. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? New UT. Closes #27649 from HeartSaVioR/SPARK-30900.

[SPARK-33530][CORE] Support --archives and spark.archives option nati…
…vely ### What changes were proposed in this pull request? TL;DR: - This PR completes the support of archives in Spark itself instead of Yarn-only - It makes `--archives` option work in other cluster modes too and adds `spark.archives` configuration. - After this PR, PySpark users can leverage Conda to ship Python packages together as below: ```python conda create -y -n pyspark_env -c conda-forge pyarrow==2.0.0 pandas==1.1.4 conda-pack==0.5.0 conda activate pyspark_env conda pack -f -o pyspark_env.tar.gz PYSPARK_DRIVER_PYTHON=python PYSPARK_PYTHON=./environment/bin/python pyspark --archives pyspark_env.tar.gz#environment ``` - Issue a warning that undocumented and hidden behavior of partial archive handling in `spark.files` / `SparkContext.addFile` will be deprecated, and users can use `spark.archives` and `SparkContext.addArchive`. This PR proposes to add Spark's native `--archives` in Spark submit, and `spark.archives` configuration. Currently, both are supported only in Yarn mode: ```bash ./bin/spark-submit --help ``` ``` Options: ... Spark on YARN only: --queue QUEUE_NAME The YARN queue to submit to (Default: "default"). --archives ARCHIVES Comma separated list of archives to be extracted into the working directory of each executor. ``` This `archives` feature is useful often when you have to ship a directory and unpack into executors. One example is native libraries to use e.g. JNI. Another example is to ship Python packages together by Conda environment. Especially for Conda, PySpark currently does not have a nice way to ship a package that works in general, please see also https://hyukjin-spark.readthedocs.io/en/stable/user_guide/python_packaging.html#using-zipped-virtual-environment (PySpark new documentation demo for 3.1.0). The neatest way is arguably to use Conda environment by shipping zipped Conda environment but this is currently dependent on this archive feature. NOTE that we are able to use `spark.files` by relying on its undocumented behaviour that untars `tar.gz` but I don't think we should document such ways and promote people to more rely on it. Also, note that this PR does not target to add the feature parity of `spark.files.overwrite`, `spark.files.useFetchCache`, etc. yet. I documented that this is an experimental feature as well. ### Why are the changes needed? To complete the feature parity, and to provide a better support of shipping Python libraries together with Conda env. ### Does this PR introduce _any_ user-facing change? Yes, this makes `--archives` works in Spark instead of Yarn-only, and adds a new configuration `spark.archives`. ### How was this patch tested? I added unittests. Also, manually tested in standalone cluster, local-cluster, and local modes. Closes #30486 from HyukjinKwon/native-archive.

[SPARK-27188][SS] FileStreamSink: provide a new option to have retent…
…ion on output files ### What changes were proposed in this pull request? This patch proposes to provide a new option to specify time-to-live (TTL) for output file entries in FileStreamSink. TTL is defined via current timestamp - the last modified time for the file. This patch will filter out outdated output files in metadata while compacting batches (other batches don't have functionality to clean entries), which helps metadata to not grow linearly, as well as filtered out files will be "eventually" no longer seen in reader queries which leverage File(Stream)Source. ### Why are the changes needed? The metadata log greatly helps to easily achieve exactly-once but given the output path is open to arbitrary readers, there's no way to compact the metadata log, which ends up growing the metadata file as query runs for long time, especially for compacted batch. Lots of end users have been reporting the issue: see comments in [SPARK-24295](https://issues.apache.org/jira/browse/SPARK-24295) and [SPARK-29995](https://issues.apache.org/jira/browse/SPARK-29995), and [SPARK-30462](https://issues.apache.org/jira/browse/SPARK-30462). (There're some reports from end users which include their workarounds: SPARK-24295) ### Does this PR introduce any user-facing change? No, as the configuration is new and by default it is not applied. ### How was this patch tested? New UT. Closes #28363 from HeartSaVioR/SPARK-27188-v2.

[SPARK-32032][SS] Avoid infinite wait in driver because of KafkaConsu…
…mer.poll(long) API ### What changes were proposed in this pull request? Deprecated `KafkaConsumer.poll(long)` API calls may cause infinite wait in the driver. In this PR I've added a new `AdminClient` based offset fetching which is turned off by default. There is a new flag named `spark.sql.streaming.kafka.useDeprecatedOffsetFetching` (default: `true`) which can be set to `false` to reach the newly added functionality. The Structured Streaming migration guide contains more information what migration consideration must be done. Please see the following [doc](https://docs.google.com/document/d/1gAh0pKgZUgyqO2Re3sAy-fdYpe_SxpJ6DkeXE8R1P7E/edit?usp=sharing) for further details. The PR contains the following changes: * Added `AdminClient` based offset fetching * GroupId prefix feature removed from driver but only in `AdminClient` based approach (`AdminClient` doesn't need any GroupId) * GroupId override feature removed from driver but only in `AdminClient` based approach (`AdminClient` doesn't need any GroupId) * Additional unit tests * Code comment changes * Minor bugfixes here and there * Removed Kafka auto topic creation feature but only in `AdminClient` based approach (please see doc for rationale). In short, it's super hidden, not sure anybody ever used in production + error prone. * Added documentation to `ss-migration-guide` and `structured-streaming-kafka-integration` ### Why are the changes needed? Driver may hang forever. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing + additional unit tests. Cluster test with simple Kafka topic to another topic query. Documentation: ``` cd docs/ SKIP_API=1 jekyll build ``` Manual webpage check. Closes #29729 from gaborgsomogyi/SPARK-32032.

Spark already support `LIKE ANY` syntax, but it will throw `StackOverflowError` if there are many elements(more than 14378 elements). We should implement built-in function for LIKE ANY to fix this issue. Why the stack overflow can happen in the current approach ? The current approach uses reduceLeft to connect each `Like(e, p)`, this will lead the the call depth of the thread is too large, causing `StackOverflowError` problems.

[SPARK-33612][SQL] Add dataSourceRewriteRules batch to Optimizer
### What changes were proposed in this pull request? This PR adds a new batch to the optimizer for executing rules that rewrite plans for data sources. ### Why are the changes needed? Right now, we have a special place in the optimizer where we construct v2 scans. As time shows, we need more rewrite rules that would be executed after the operator optimization and before any stats-related rules for v2 tables. Not all rules will be specific to reads. One option is to rename the current batch into something more generic but it would require changing quite some places. That's why it seems better to introduce a new batch and use it for all rewrites. The name is generic so that we don't limit ourselves to v2 data sources only. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The change is trivial and SPARK-23889 will depend on it. Closes #30558 from aokolnychyi/spark-33612.

[SPARK-33611][UI] Avoid encoding twice on the query parameter of rewr…
…itten proxy URL ### What changes were proposed in this pull request? When running Spark behind a reverse proxy(e.g. Nginx, Apache HTTP server), the request URL can be encoded twice if we pass the query string directly to the constructor of `java.net.URI`: ``` > val uri = "http://localhost:8081/test" > val query = "order%5B0%5D%5Bcolumn%5D=0" // query string of URL from the reverse proxy > val rewrittenURI = URI.create(uri.toString()) > new URI(rewrittenURI.getScheme(), rewrittenURI.getAuthority(), rewrittenURI.getPath(), query, rewrittenURI.getFragment()).toString result: http://localhost:8081/test?order%255B0%255D%255Bcolumn%255D=0 ``` In Spark's stage page, the URL of "/taskTable" contains query parameter order[0][dir]. After encoding twice, the query parameter becomes `order%255B0%255D%255Bdir%255D` and it will be decoded as `order%5B0%5D%5Bdir%5D` instead of `order[0][dir]`. As a result, there will be NullPointerException from https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/status/api/v1/StagesResource.scala#L176 Other than that, the other parameter may not work as expected after encoded twice. This PR is to fix the bug by calling the method `URI.create(String URL)` directly. This convenience method can avoid encoding twice on the query parameter. ``` > val uri = "http://localhost:8081/test" > val query = "order%5B0%5D%5Bcolumn%5D=0" > URI.create(s"$uri?$query").toString result: http://localhost:8081/test?order%5B0%5D%5Bcolumn%5D=0 > URI.create(s"$uri?$query").getQuery result: order[0][column]=0 ``` ### Why are the changes needed? Fix a potential bug when Spark's reverse proxy is enabled. The bug itself is similar to #29271. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Add a new unit test. Also, Manual UI testing for master, worker and app UI with an nginx proxy Spark config: ``` spark.ui.port 8080 spark.ui.reverseProxy=true spark.ui.reverseProxyUrl=/path/to/spark/ ``` nginx config: ``` server { listen 9000; set $SPARK_MASTER http://127.0.0.1:8080; # split spark UI path into prefix and local path within master UI location ~ ^(/path/to/spark/) { # strip prefix when forwarding request rewrite /path/to/spark(/.*) $1 break; #rewrite /path/to/spark/ "/" ; # forward to spark master UI proxy_pass $SPARK_MASTER; proxy_intercept_errors on; error_page 301 302 307 = handle_redirects; } location handle_redirects { set $saved_redirect_location '$upstream_http_location'; proxy_pass $saved_redirect_location; } } ``` Closes #30552 from gengliangwang/decodeProxyRedirect.

[SPARK-33544][SQL] Optimize size of CreateArray/CreateMap to be the s…
…ize of its children ### What changes were proposed in this pull request? https://issues.apache.org/jira/browse/SPARK-32295 added in an optimization to insert a filter for not null and size > 0 when using inner explode/inline. This is fine in most cases but the extra filter is not needed if the explode is with a create array and not using Literals (it already handles LIterals). When this happens you know that the values aren't null and it has a size. It already handles the empty array. The not null check is already optimized out because Createarray and createMap are not nullable, that leaves the size > 0 check. To handle that this PR makes it so that the size > 0 check gets optimized in ConstantFolding to be the size of the children in the array or map. That makes it a literal and then makes it ultimately be optimized out. ### Why are the changes needed? remove unneeded filter ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? Unit tests added and manually tested various cases Closes #30504 from tgravescs/SPARK-33544.

[SPARK-32863][SS] Full outer stream-stream join
### What changes were proposed in this pull request? This PR is to add full outer stream-stream join, and the implementation of full outer join is: * For left side input row, check if there's a match on right side state store. * if there's a match, output the joined row, o.w. output nothing. Put the row in left side state store. * For right side input row, check if there's a match on left side state store. * if there's a match, output the joined row, o.w. output nothing. Put the row in right side state store. * State store eviction: evict rows from left/right side state store below watermark, and output rows never matched before (a combination of left outer and right outer join). ### Why are the changes needed? Enable more use cases for spark stream-stream join. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Added unit tests in `UnsupportedOperationChecker.scala` and `StreamingJoinSuite.scala`. Closes #30395 from c21/stream-foj.

[MINOR][SS] Rename auxiliary protected methods in StreamingJoinSuite
### What changes were proposed in this pull request? Per request from #30395 (comment), here we remove `Windowed` from methods names `setupWindowedJoinWithRangeCondition` and `setupWindowedSelfJoin` as they don't join on time window. ### Why are the changes needed? There's no such official name for `windowed join`, so this is to help avoid confusion for future developers. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing unit tests. Closes #30563 from c21/stream-minor. Authored-by: Cheng Su <chengsu@fb.com> Signed-off-by: Jungtaek Lim (HeartSaVioR) <kabhwan.opensource@gmail.com>

… make hadoop-aws work ### What changes were proposed in this pull request? This reverts commit SPARK-33212 (cb3fa6c) mostly with three exceptions: 1. `SparkSubmitUtils` was updated recently by SPARK-33580 2. `resource-managers/yarn/pom.xml` was updated recently by SPARK-33104 to add `hadoop-yarn-server-resourcemanager` test dependency. 3.

…AGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT and NETWORK_TIMEOUT ### What changes were proposed in this pull request? As described in SPARK-33557, `HeartbeatReceiver` and `MesosCoarseGrainedSchedulerBackend` will always use `Network.NETWORK_TIMEOUT.defaultValueString` as value of `STORAGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT` when we configure `NETWORK_TIMEOUT` without configure `STORAGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT`, this is different from the relationship described in `configuration.md`. To fix this problem,the main change of this pr as follow: - Remove the explicitly default value of `STORAGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT` - Use actual value of `NETWORK_TIMEOUT` as `STORAGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT` when `STORAGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT` not configured in `HeartbeatReceiver` and `MesosCoarseGrainedSchedulerBackend` ### Why are the changes needed? To ensure the relationship between `NETWORK_TIMEOUT` and `STORAGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT` as we described in `configuration.md` ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? - Pass the Jenkins or GitHub Action - Manual test configure `NETWORK_TIMEOUT` and `STORAGE_BLOCKMANAGER_HEARTBEAT_TIMEOUT` locally Closes #30547 from LuciferYang/SPARK-33557.

[SPARK-33544][SQL][FOLLOW-UP] Rename NoSideEffect to NoThrow and clar…
…ify the documentation more ### What changes were proposed in this pull request? This PR is a followup of #30504. It proposes: - Rename `NoSideEffect` to `NoThrow`, and use `Expression.deterministic` together where it is used. - Clarify, in the docs in the expressions, that it means they don't throw exceptions ### Why are the changes needed? `NoSideEffect` virtually means that `Expression.eval` does not throw an exception, and the expressions are deterministic. It's best to be explicit so `NoThrow` was proposed - I looked if there's a similar name to represent this concept and borrowed the name of [nothrow](https://clang.llvm.org/docs/AttributeReference.html#nothrow). For determinism, we already have a way to note it under `Expression.deterministic`. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?

[SPARK-33071][SPARK-33536][SQL] Avoid changing dataset_id of LogicalP…
…lan in join() to not break DetectAmbiguousSelfJoin ### What changes were proposed in this pull request? Currently, `join()` uses `withPlan(logicalPlan)` for convenient to call some Dataset functions. But it leads to the `dataset_id` inconsistent between the `logicalPlan` and the original `Dataset`(because `withPlan(logicalPlan)` will create a new Dataset with the new id and reset the `dataset_id` with the new id of the `logicalPlan`). As a result, it breaks the rule `DetectAmbiguousSelfJoin`. In this PR, we propose to drop the usage of `withPlan` but use the `logicalPlan` directly so its `dataset_id` doesn't change. Besides, this PR also removes related metadata (`DATASET_ID_KEY`, `COL_POS_KEY`) when an `Alias` tries to construct its own metadata. Because the `Alias` is no longer a reference column after converting to an `Attribute`. To achieve that, we add a new field, `deniedMetadataKeys`, to indicate the metadata that needs to be removed. ### Why are the changes needed? For the query below, it returns the wrong result while it should throws ambiguous self join exception instead: ```scala val emp1 = Seq[TestData]( TestData(1, "sales"), TestData(2, "personnel"), TestData(3, "develop"), TestData(4, "IT")).toDS() val emp2 = Seq[TestData]( TestData(1, "sales"), TestData(2, "personnel"), TestData(3, "develop")).toDS() val emp3 = emp1.join(emp2, emp1("key") === emp2("key")).select(emp1("*")) emp1.join(emp3, emp1.col("key") === emp3.col("key"), "left_outer") .select(emp1.col("*"), emp3.col("key").as("e2")).show() // wrong result +---+---------+---+ |key| value| e2| +---+---------+---+ | 1| sales| 1| | 2|personnel| 2| | 3| develop| 3| | 4| IT| 4| +---+---------+---+ ``` This PR fixes the wrong behaviour. ### Does this PR introduce _any_ user-facing change? Yes, users hit the exception instead of the wrong result after this PR. ### How was this patch tested? Added a new unit test. Closes #30488 from Ngone51/fix-self-join.

[SPARK-30098][SQL] Add a configuration to use default datasource as p…
…rovider for CREATE TABLE command ### What changes were proposed in this pull request? For CRETE TABLE [AS SELECT] command, creates native Parquet table if neither USING nor STORE AS is specified and `spark.sql.legacy.createHiveTableByDefault` is false. This is a retry after we unify the CREATE TABLE syntax. It partially reverts d2bec5e This PR allows `CREATE EXTERNAL TABLE` when `LOCATION` is present. This was not allowed for data source tables before, which is an unnecessary behavior different with hive tables. ### Why are the changes needed? Changing from Hive text table to native Parquet table has many benefits: 1. be consistent with `DataFrameWriter.saveAsTable`. 2. better performance 3. better support for nested types (Hive text table doesn't work well with nested types, e.g. `insert into t values struct(null)` actually inserts a null value not `struct(null)` if `t` is a Hive text table, which leads to wrong result) 4. better interoperability as Parquet is a more popular open file format. ### Does this PR introduce _any_ user-facing change? No by default. If the config is set, the behavior change is described below: Behavior-wise, the change is very small as the native Parquet table is also Hive-compatible. All the Spark DDL commands that works for hive tables also works for native Parquet tables, with two exceptions: `ALTER TABLE SET [SERDE | SERDEPROPERTIES]` and `LOAD DATA`. char/varchar behavior has been taken care by #30412, and there is no behavior difference between data source and hive tables. One potential issue is `CREATE TABLE ... LOCATION ...` while users want to directly access the files later. It's more like a corner case and the legacy config should be good enough. Another potential issue is users may use Spark to create the table and then use Hive to add partitions with different serde. This is not allowed for Spark native tables. ### How was this patch tested? Re-enable the tests Closes #30554 from cloud-fan/create-table.

[SPARK-33623][SQL] Add canDeleteWhere to SupportsDelete
### What changes were proposed in this pull request? This PR provides us with a way to check if a data source is going to reject the delete via `deleteWhere` at planning time. ### Why are the changes needed? The only way to support delete statements right now is to implement ``SupportsDelete``. According to its Javadoc, that interface is meant for cases when we can delete data without much effort (e.g. like deleting a complete partition in a Hive table). This PR actually provides us with a way to check if a data source is going to reject the delete via `deleteWhere` at planning time instead of just getting an exception during execution. In the future, we can use this functionality to decide whether Spark should rewrite this delete and execute a distributed query or it can just pass a set of filters. Consider an example of a partitioned Hive table. If we have a delete predicate like `part_col = '2020'`, we can just drop the matching partition to satisfy this delete. In this case, the data source should return `true` from `canDeleteWhere` and use the filters it accepts in `deleteWhere` to drop the partition. I consider this as a delete without significant effort. At the same time, if we have a delete predicate like `id = 10`, Hive tables would not be able to execute this delete using a metadata only operation without rewriting files. In that case, the data source should return `false` from `canDeleteWhere` and we should use a more sophisticated row-level API to find out which records should be removed (the API is yet to be discussed, but we need this PR as a basis). If we decide to support subqueries and all delete use cases by simply extending the existing API, this will mean all data sources will have to implement a lot of Spark logic to determine which records changed. I don't think we want to go that way as the Spark logic to determine which records should be deleted is independent of the underlying data source. So the assumption is that Spark will execute a plan to find which records must be deleted for data sources that return `false` from `canDeleteWhere`. ### Does this PR introduce _any_ user-facing change? Yes but it is backward compatible. ### How was this patch tested? This PR comes with a new test. Closes #30562 from aokolnychyi/spark-33623.

…VsRest Reader/Writer support Python backend estimator/evaluator ### What changes were proposed in this pull request? make CrossValidator/TrainValidateSplit/OneVsRest Reader/Writer support Python backend estimator/model ### Why are the changes needed? Currently, pyspark support third-party library to define python backend estimator/evaluator, i.e., estimator that inherit `Estimator` instead of `JavaEstimator`, and only can be used in pyspark. CrossValidator and TrainValidateSplit support tuning these python backend estimator, but cannot support saving/load, becase CrossValidator and TrainValidateSplit writer implementation is use JavaMLWriter, which require to convert nested estimator and evaluator into java instance. OneVsRest saving/load now only support java backend classifier due to similar issue. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Unit test.

[SPARK-33650][SQL] Fix the error from ALTER TABLE .. ADD/DROP PARTITI…
…ON for non-supported partition management table ### What changes were proposed in this pull request? In the PR, I propose to change the order of post-analysis checks for the `ALTER TABLE .. ADD/DROP PARTITION` command, and perform the general check (does the table support partition management at all) before specific checks. ### Why are the changes needed? The error message for the table which doesn't support partition management can mislead users: ```java PartitionSpecs are not resolved;; 'AlterTableAddPartition [UnresolvedPartitionSpec(Map(id -> 1),None)], false +- ResolvedTable org.apache.spark.sql.connector.InMemoryTableCatalog2fd64b11, ns1.ns2.tbl, org.apache.spark.sql.connector.InMemoryTable5d3ff859 ``` because it says nothing about the root cause of the issue. ### Does this PR introduce _any_ user-facing change? Yes. After the change, the error message will be: ``` Table ns1.ns2.tbl can not alter partitions ``` ### How was this patch tested? By running the affected test suite `AlterTablePartitionV2SQLSuite`.

[SPARK-27237][SS] Introduce State schema validation among query restart
## What changes were proposed in this pull request? Please refer the description of [SPARK-27237](https://issues.apache.org/jira/browse/SPARK-27237) to see rationalization of this patch. This patch proposes to introduce state schema validation, via storing key schema and value schema to `schema` file (for the first time) and verify new key schema and value schema for state are compatible with existing one. To be clear for definition of "compatible", state schema is "compatible" when number of fields are same and data type for each field is same - Spark has been allowing rename of field. This patch will prevent query run which has incompatible state schema, which would reduce the chance to get indeterministic behavior (actually renaming of field is also the smell of semantically incompatible, but end users could just modify its name so we can't say) as well as providing more informative error message. ## How was this patch tested? Added UTs. Closes #24173 from HeartSaVioR/SPARK-27237.

[SPARK-33615][K8S] Make 'spark.archives' working in Kubernates

It works without a problem in standalone cluster but there seems a bug in Kubernates. It fails to fetch the file on the driver side as below: ``` 20/12/03 13:33:53 INFO SparkContext: Added JAR file:/tmp/spark-75004286-c83a-4369-b624-14c5d2d2a748/spark-examples_2.12-3.1.0-SNAPSHOT.jar at spark://spark-test-app-48ae737628cee6f8-driver-svc.spark-integration-test.svc:7078/jars/spark-examples_2.12-3.1.0-SNAPSHOT.jar with timestamp 1607002432558 20/12/03 13:33:53 INFO SparkContext: Added archive file:///tmp/tmp4542734800151332666.txt.tar.gz#test_tar_gz at spark://spark-test-app-48ae737628cee6f8-driver-svc.spark-integration-test.svc:7078/files/tmp4542734800151332666.txt.tar.gz with timestamp 1607002432558 20/12/03 13:33:53 INFO TransportClientFactory: Successfully created connection to spark-test-app-48ae737628cee6f8-driver-svc.spark-integration-test.svc/172.17.0.4:7078 after 83 ms (47 ms spent in bootstraps) 20/12/03 13:33:53 INFO Utils: Fetching spark://spark-test-app-48ae737628cee6f8-driver-svc.spark-integration-test.svc:7078/files/tmp4542734800151332666.txt.tar.gz to /tmp/spark-66573e24-27a3-427c-99f4-36f06d9e9cd5/fetchFileTemp2665785666227461849.tmp 20/12/03 13:33:53 ERROR SparkContext: Error initializing SparkContext. java.lang.RuntimeException: Stream '/files/tmp4542734800151332666.txt.tar.gz' was not found. at org.apache.spark.network.client.TransportResponseHandler.handle(TransportResponseHandler.java:242) at org.apache.spark.network.server.TransportChannelHandler.channelRead0(TransportChannelHandler.java:142) at org.apache.spark.network.server.TransportChannelHandler.channelRead0(TransportChannelHandler.java:53) ``` This is because `spark.archives` was not actually added on the driver side correctly. The changes here fix it by adding and resolving URIs correctly. ### Why are the changes needed? `spark.archives` feature can be leveraged for many things such as Conda support.

[SPARK-33651][SQL] Allow CREATE EXTERNAL TABLE with LOCATION for data…
… source tables ### What changes were proposed in this pull request? This PR removes the restriction and allows CREATE EXTERNAL TABLE with LOCATION for data source tables. It also moves the check from the analyzer rule `ResolveSessionCatalog` to `SessionCatalog`, so that v2 session catalog can overwrite it. ### Why are the changes needed? It's an unnecessary behavior difference that Hive serde table can be created with `CREATE EXTERNAL TABLE` if LOCATION is present, while data source table doesn't allow `CREATE EXTERNAL TABLE` at all. ### Does this PR introduce _any_ user-facing change? Yes, now `CREATE EXTERNAL TABLE ... USING ... LOCATION ...` is allowed. ### How was this patch tested? new tests Closes #30595 from cloud-fan/minor.

… is picked from the provided ### What changes were proposed in this pull request? Fix flaky test "Verify logging configuration is picked from the provided SPARK_CONF_DIR/log4j.properties." The test is flaking, with multiple flaked instances - the reason for the failure has been similar to: ``` The code passed to eventually never returned normally. Attempted 109 times over 3.0079882413999997 minutes. Last failure message: Failure executing: GET at: https://192.168.39.167:8443/api/v1/namespaces/b37fc72a991b49baa68a2eaaa1516463/pods/spark-pi-97a9bc76308e7fe3-exec-1/log?pretty=false.

So, in order to mitigate this situation, one way is to turn on the flag "spark.kubernetes.executor.deleteOnTermination" ### Why are the changes needed? Fixes a flaky test. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Existing tests. May be a few runs of jenkins integration test, may reveal if the problem is resolved or not. Closes #30616 from ScrapCodes/SPARK-33668/fix-flaky-k8s-integration-test.

[SPARK-33652][SQL] DSv2: DeleteFrom should refresh cache
### What changes were proposed in this pull request? This changes `DeleteFromTableExec` to also refresh caches referencing the original table, by passing the `refreshCache` callback to the class. Note that in order to construct the callback, I have to change `DataSourceV2ScanRelation` to contain a `DataSourceV2Relation` instead of a `Table`. ### Why are the changes needed? Currently DSv2 delete from table doesn't refresh caches. This could lead to correctness issue if the staled cache is queried later. ### Does this PR introduce _any_ user-facing change? Yes. Now delete from table in v2 also refreshes cache. ### How was this patch tested? Added a test case. Closes #30597 from sunchao/SPARK-33652.

[SPARK-33256][PYTHON][DOCS] Clarify PySpark follows NumPy documentati…
…on style ### What changes were proposed in this pull request? This PR adds few lines about docstring style to document that PySpark follows [NumPy documentation style](https://numpydoc.readthedocs.io/en/latest/format.html). We all completed the migration to NumPy documentation style at SPARK-32085. Ideally we should have a page like https://pandas.pydata.org/docs/development/contributing_docstring.html but I would like to leave it as a future work. ### Why are the changes needed? To tell developers that PySpark now follows NumPy documentation style. ### Does this PR introduce _any_ user-facing change? No, it's a change in unreleased branches yet. ### How was this patch tested? Manually tested via `make clean html` under `python/docs`: ![Screen Shot 2020-12-06 at 1 34 50 PM](https://user-images.githubusercontent.com/6477701/101271623-d5ce0380-37c7-11eb-93ac-da73caa50c37.png) Closes #30622 from HyukjinKwon/SPARK-33256.

[SPARK-33667][SQL] Respect the
spark.sql.caseSensitive
config while…… resolving partition spec in v1 `SHOW PARTITIONS` ### What changes were proposed in this pull request? Preprocess the partition spec passed to the V1 SHOW PARTITIONS implementation `ShowPartitionsCommand`, and normalize the passed spec according to the partition columns w.r.t the case sensitivity flag **spark.sql.caseSensitive**. ### Why are the changes needed? V1 SHOW PARTITIONS is case sensitive in fact, and doesn't respect the SQL config **spark.sql.caseSensitive** which is false by default, for instance: ```sql spark-sql> CREATE TABLE tbl1 (price int, qty int, year int, month int) > USING parquet > PARTITIONED BY (year, month); spark-sql> INSERT INTO tbl1 PARTITION(year = 2015, month = 1) SELECT 1, 1; spark-sql> SHOW PARTITIONS tbl1 PARTITION(YEAR = 2015, Month = 1); Error in query: Non-partitioning column(s) [YEAR, Month] are specified for SHOW PARTITIONS; ``` The `SHOW PARTITIONS` command must show the partition `year = 2015, month = 1` specified by `YEAR = 2015, Month = 1`. ### Does this PR introduce _any_ user-facing change? Yes. After the changes, the command above works as expected: ```sql spark-sql> SHOW PARTITIONS tbl1 PARTITION(YEAR = 2015, Month = 1); year=2015/month=1 ``` ### How was this patch tested? By running the affected test suites: - `v1/ShowPartitionsSuite` - `v2/ShowPartitionsSuite` Closes #30615 from MaxGekk/show-partitions-case-sensitivity-test.

[SPARK-33674][TEST] Show Slowpoke notifications in SBT tests
### What changes were proposed in this pull request? This PR is to show Slowpoke notifications in the log when running tests using SBT. For example, the test case "zero sized blocks" in ExternalShuffleServiceSuite enters the infinite loop. After this change, the log file will have a notification message every 5 minute when the test case running longer than two minutes. Below is an example message. ``` [info] ExternalShuffleServiceSuite: [info] - groupByKey without compression (101 milliseconds) [info] - shuffle non-zero block size (3 seconds, 186 milliseconds) [info] - shuffle serializer (3 seconds, 189 milliseconds) [info] *** Test still running after 2 minute, 1 seconds: suite name: ExternalShuffleServiceSuite, test name: zero sized blocks. [info] *** Test still running after 7 minute, 1 seconds: suite name: ExternalShuffleServiceSuite, test name: zero sized blocks. [info] *** Test still running after 12 minutes, 1 seconds: suite name: ExternalShuffleServiceSuite, test name: zero sized blocks. [info] *** Test still running after 17 minutes, 1 seconds: suite name: ExternalShuffleServiceSuite, test name: zero sized blocks. ``` ### Why are the changes needed? When the tests/code has bug and enters the infinite loop, it is hard to tell which test cases hit some issues from the log, especially when we are running the tests in parallel. It would be nice to show the Slowpoke notifications. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Manual testing in my local dev environment. Closes #30621 from gatorsmile/addSlowpoke. Authored-by: Xiao Li <gatorsmile@gmail.com> Signed-off-by: Yuming Wang <yumwang@ebay.com>

[SPARK-33675][INFRA] Add GitHub Action job to publish snapshot
### What changes were proposed in this pull request? This PR aims to add `GitHub Action` job to publish daily snapshot for **master** branch. - https://repository.apache.org/content/groups/snapshots/org/apache/spark/spark-core_2.12/3.2.0-SNAPSHOT/ For the other branches, I'll make adjusted backports. - For `branch-3.1`, we can specify the checkout `ref` to `branch-3.1`. - For `branch-2.4` and `branch-3.0`, we can publish at every commit since the traffic is low. - #30630 (branch-3.0) - #30629 (branch-2.4 LTS) ### Why are the changes needed? After this series of jobs, this will reduce our maintenance burden permanently from AmpLab Jenkins by removing the following completely. https://amplab.cs.berkeley.edu/jenkins/view/Spark%20Packaging/ For now, AmpLab Jenkins doesn't have a job for `branch-3.1`. We can do it by ourselves by `GitHub Action`. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The snapshot publishing is tested here at PR trigger. Since this PR adds a scheduled job, we cannot test in this PR. - https://github.com/dongjoon-hyun/spark/runs/1505792859 Apache Infra team finished the setup here. - https://issues.apache.org/jira/browse/INFRA-21167 Closes #30623 from dongjoon-hyun/SPARK-33675.

Invoke the check `DDLUtils.verifyPartitionProviderIsHive()` from V1 implementation of `SHOW TABLE EXTENDED` when partition specs are specified. This PR is some kind of follow up #16373 and #15515. ### Why are the changes needed? To output an user friendly error with recommendation like **" ... partition metadata is not stored in the Hive metastore. To import this information into the metastore, run `msck repair table tableName` "** instead of silently output an empty result. ### Does this PR introduce _any_ user-facing change? Yes. ### How was this patch tested? By running the affected test suites, in particular: ``` $ build/sbt -Phive-2.3 -Phive-thriftserver "hive/test:testOnly *PartitionProviderCompatibilitySuite" ``` Closes #30618 from MaxGekk/show-table-extended-verifyPartitionProviderIsHive.

[SPARK-33693][SQL] deprecate spark.sql.hive.convertCTAS
### What changes were proposed in this pull request? This is a followup of #30554 . Now we have a new config for converting CREATE TABLE, we don't need the old config that only works for CTAS. ### Why are the changes needed? It's confusing for having two config while one can cover another completely. ### Does this PR introduce _any_ user-facing change? no, it's deprecating not removing. ### How was this patch tested?

[SPARK-33480][SQL][FOLLOWUP] do not expose user data in error message
### What changes were proposed in this pull request? This is a followup of #30412. This PR updates the error message of char/varchar table insertion length check, to not expose user data. ### Why are the changes needed? This is risky to expose user data in the error message, especially the string data, as it may contain sensitive data. ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? updated tests Closes #30653 from cloud-fan/minor2.

[SPARK-33621][SQL] Add a way to inject data source rewrite rules
### What changes were proposed in this pull request? This PR adds a way to inject data source rewrite rules. ### Why are the changes needed? Right now `SparkSessionExtensions` allow us to inject optimization rules but they are added to operator optimization batch. There are cases when users need to run rules after the operator optimization batch (e.g. cases when a rule relies on the fact that expressions have been optimized). Currently, this is not possible. ### Does this PR introduce _any_ user-facing change? Yes. ### How was this patch tested? This PR comes with a new test. Closes #30577 from aokolnychyi/spark-33621-v3.

[SPARK-33664][SQL] Migrate ALTER TABLE ... RENAME TO to use Unresolve…
…dTableOrView to resolve identifier ### What changes were proposed in this pull request? This PR proposes to migrate `ALTER [TABLE|ViEW] ... RENAME TO` to use `UnresolvedTableOrView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing). ### Why are the changes needed? To use `UnresolvedTableOrView` for table/view resolution. Note that `AlterTableRenameCommand` internally resolves to a temp view first, so there is no resolution behavior change with this PR. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Updated existing tests. Closes #30610 from imback82/rename_v2. Authored-by: Terry Kim <yuminkim@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com>

…ework ### What changes were proposed in this pull request? 1. Remove old statement `ShowTableStatement` 2. Introduce new command `ShowTableExtended` for `SHOW TABLE EXTENDED`. This PR is the first step of new V2 implementation of `SHOW TABLE EXTENDED`, see SPARK-33393. ### Why are the changes needed? This is a part of effort to make the relation lookup behavior consistent: SPARK-29900. ### Does this PR introduce _any_ user-facing change? The changes should not affect V1 tables. For V2, Spark outputs the error: ``` SHOW TABLE EXTENDED is not supported for v2 tables. ``` ### How was this patch tested? By running `SHOW TABLE EXTENDED` tests: ``` $ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *ShowTablesSuite" ``` Closes #30645 from MaxGekk/show-table-extended-statement.
