python/pyspark/rdd.py

+        Hash-partitions the resulting RDD into the given number of partitions.

+        >>> x = sc.parallelize([("a", 1), ("b", 4)])
+        >>> y = sc.parallelize([("a", 2)])


Exercise both None possibilities; e.g. y = sc.parallelize([("a", 2), ("c", 1)])

That is just a comment. I can update to include that case ... is that what you had in mind?

Yeah, at least the comment should reflect both cases, but it's more than just a comment.

Looks good and complete. It'll take some simple changes (ClassManifest -> ClassTag, relocation of PairDStreamFunctions.scala, Java API now using Guava Optional instead of Scala Option, and maybe one or two others) to make it ready for 1.1.0 (too late for 1.0.0), but that's all straightforward. I don't see any prior fullOuterJoin contribution effort, and Matei resisted the suggestion that the current joins be trimmed out of the standard Spark API, so it's likely this PR (modified for 1.1.x) could be merged into Apache Spark.

There's also this: SPARK-546

re: SPARK-546 - that seems to identify two separate issues:

full outer join
cogrouping more than two RDD's at a time (to optimize for equi-joins for

2 views). The current CoGroup'ing scheme in spark does not support
multiple RDD's/tables and I'm not sure the DAG scheduler will handle
collapsing the shuffle dependencies to perform a co-partitioning for
multiple RDD's.

I think we can say we partially address this issue but this issue needs to
be refined or broken into multiple tickets.

Agreed. That's also a two year-old JIRA issue, so the best strategy to follow for the second part is likely different from what Reynold was thinking anyway.

jhartlaub · 2014-04-08T17:45:40Z

looks good to me

vnivargi · 2014-04-08T18:11:56Z

updated for doctest

markhamstra · 2014-04-08T18:48:17Z

@vachanw That SparkListenerSuite failure is a known flaky test that has been reworked in more recent releases of Spark. We should probably just ignore failures in at least the "local metrics" test.

adding full outer join support

When debugging Spark Streaming applications it is necessary to monitor certain metrics that are not shown in the Spark application UI. For example, what is average processing time of batches? What is the scheduling delay? Is the system able to process as fast as it is receiving data? How many records I am receiving through my receivers? While the StreamingListener interface introduced in the 0.9 provided some of this information, it could only be accessed programmatically. A UI that shows information specific to the streaming applications is necessary for easier debugging. This PR introduces such a UI. It shows various statistics related to the streaming application. Here is a screenshot of the UI running on my local machine. http://i.imgur.com/1ooDGhm.png This UI is integrated into the Spark UI running at 4040.

This patch allows the FaultToleranceTest to work in newer versions of Docker. See https://spark-project.atlassian.net/browse/SPARK-1136 for more details. Besides changing the Docker and FaultToleranceTest internals, this patch also changes the behavior of Master to accept new Workers which share an address with a Worker that we are currently trying to recover. This can only happen when the Worker itself was restarted and got the same IP address/port at the same time as a Master recovery occurs. Finally, this adds a good bit of ASCII art to the test to make failures, successes, and actions more apparent. This is very much needed.

This pull request adds support to Spark for working with structured data using a simple SQL dialect, HiveQL and a Scala Query DSL. *This is being contributed as a new __alpha component__ to Spark and does not modify Spark core or other components.* The code is broken into three primary components: - Catalyst (sql/catalyst) - An implementation-agnostic framework for manipulating trees of relational operators and expressions. - Execution (sql/core) - A query planner / execution engine for translating Catalyst’s logical query plans into Spark RDDs. This component also includes a new public interface, SqlContext, that allows users to execute SQL or structured scala queries against existing RDDs and Parquet files. - Hive Metastore Support (sql/hive) - An extension of SqlContext called HiveContext that allows users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allows users to run queries that include Hive UDFs, UDAFs, and UDTFs. A more complete design of this new component can be found in [the associated JIRA](https://spark-project.atlassian.net/browse/SPARK-1251). [An updated version of the Spark documentation, including API Docs for all three sub-components,](http://people.apache.org/~pwendell/catalyst-docs/sql-programming-guide.html) is also available for review. With this PR comes support for inferring the schema of existing RDDs that contain case classes. Using this information, developers can now express structured queries that are automatically compiled into RDD operations. ```scala // Define the schema using a case class. case class Person(name: String, age: Int) val people: RDD[Person] = sc.textFile("people.txt").map(_.split(",")).map(p => Person(p(0), p(1).toInt)) // The following is the same as 'SELECT name FROM people WHERE age >= 10 && age <= 19' val teenagers = people.where('age >= 10).where('age <= 19).select('name).toRdd ``` RDDs can also be registered as Tables, allowing SQL queries to be written over them. ```scala people.registerAsTable("people") val teenagers = sql("SELECT name FROM people WHERE age >= 10 && age <= 19") ``` The results of queries are themselves RDDs and support standard RDD operations: ```scala teenagers.map(t => "Name: " + t(0)).collect().foreach(println) ``` Finally, with the optional Hive support, users can read and write data located in existing Apache Hive deployments using HiveQL. ```scala sql("CREATE TABLE IF NOT EXISTS src (key INT, value STRING)") sql("LOAD DATA LOCAL INPATH 'src/main/resources/kv1.txt' INTO TABLE src") // Queries are expressed in HiveQL sql("SELECT key, value FROM src").collect().foreach(println) ``` ## Relationship to Shark Unlike Shark, Spark SQL does not act as a drop in replacement for Hive or the HiveServer. Instead this new feature is intended to make it easier for Spark developers to run queries over structured data, using either SQL or the query DSL. After this sub-project graduates from Alpha status it will likely become a new optimizer/backend for the Shark project.

@etrain and I came with a PR for arbitrarily deep decision trees at the cost of multiple passes over the data at deep tree levels. To summarize: 1) We take a parameter that indicates the amount of memory users want to reserve for computation on each worker (and 2x that at the driver). 2) Using that information, we calculate two things - the maximum depth to which we train as usual (which is, implicitly, the maximum number of nodes we want to train in parallel), and the size of the groups we should use in the case where we exceed this depth. cc: @atalwalkar, @hirakendu, @mengxr Author: Manish Amde <manish9ue@gmail.com> Author: manishamde <manish9ue@gmail.com> Author: Evan Sparks <sparks@cs.berkeley.edu> Closes apache#475 from manishamde/deep_tree and squashes the following commits: 968ca9d [Manish Amde] merged master 7fc9545 [Manish Amde] added docs ce004a1 [Manish Amde] minor formatting b27ad2c [Manish Amde] formatting 426bb28 [Manish Amde] programming guide blurb 8053fed [Manish Amde] more formatting 5eca9e4 [Manish Amde] grammar 4731cda [Manish Amde] formatting 5e82202 [Manish Amde] added documentation, fixed off by 1 error in max level calculation cbd9f14 [Manish Amde] modified scala.math to math dad9652 [Manish Amde] removed unused imports e0426ee [Manish Amde] renamed parameter 718506b [Manish Amde] added unit test 1517155 [Manish Amde] updated documentation 9dbdabe [Manish Amde] merge from master 719d009 [Manish Amde] updating user documentation fecf89a [manishamde] Merge pull request alteryx#6 from etrain/deep_tree 0287772 [Evan Sparks] Fixing scalastyle issue. 2f1e093 [Manish Amde] minor: added doc for maxMemory parameter 2f6072c [manishamde] Merge pull request alteryx#5 from etrain/deep_tree abc5a23 [Evan Sparks] Parameterizing max memory. 50b143a [Manish Amde] adding support for very deep trees

When debugging Spark Streaming applications it is necessary to monitor certain metrics that are not shown in the Spark application UI. For example, what is average processing time of batches? What is the scheduling delay? Is the system able to process as fast as it is receiving data? How many records I am receiving through my receivers? While the StreamingListener interface introduced in the 0.9 provided some of this information, it could only be accessed programmatically. A UI that shows information specific to the streaming applications is necessary for easier debugging. This PR introduces such a UI. It shows various statistics related to the streaming application. Here is a screenshot of the UI running on my local machine. http://i.imgur.com/1ooDGhm.png This UI is integrated into the Spark UI running at 4040.

@etrain and I came with a PR for arbitrarily deep decision trees at the cost of multiple passes over the data at deep tree levels. To summarize: 1) We take a parameter that indicates the amount of memory users want to reserve for computation on each worker (and 2x that at the driver). 2) Using that information, we calculate two things - the maximum depth to which we train as usual (which is, implicitly, the maximum number of nodes we want to train in parallel), and the size of the groups we should use in the case where we exceed this depth. cc: @atalwalkar, @hirakendu, @mengxr Author: Manish Amde <manish9ue@gmail.com> Author: manishamde <manish9ue@gmail.com> Author: Evan Sparks <sparks@cs.berkeley.edu> Closes apache#475 from manishamde/deep_tree and squashes the following commits: 968ca9d [Manish Amde] merged master 7fc9545 [Manish Amde] added docs ce004a1 [Manish Amde] minor formatting b27ad2c [Manish Amde] formatting 426bb28 [Manish Amde] programming guide blurb 8053fed [Manish Amde] more formatting 5eca9e4 [Manish Amde] grammar 4731cda [Manish Amde] formatting 5e82202 [Manish Amde] added documentation, fixed off by 1 error in max level calculation cbd9f14 [Manish Amde] modified scala.math to math dad9652 [Manish Amde] removed unused imports e0426ee [Manish Amde] renamed parameter 718506b [Manish Amde] added unit test 1517155 [Manish Amde] updated documentation 9dbdabe [Manish Amde] merge from master 719d009 [Manish Amde] updating user documentation fecf89a [manishamde] Merge pull request alteryx#6 from etrain/deep_tree 0287772 [Evan Sparks] Fixing scalastyle issue. 2f1e093 [Manish Amde] minor: added doc for maxMemory parameter 2f6072c [manishamde] Merge pull request alteryx#5 from etrain/deep_tree abc5a23 [Evan Sparks] Parameterizing max memory. 50b143a [Manish Amde] adding support for very deep trees (cherry picked from commit f269b01) Signed-off-by: Patrick Wendell <pwendell@gmail.com>

Streaming iterable

The ability to perform multiclass classification is a big advantage for using decision trees and was a highly requested feature for mllib. This pull request adds multiclass classification support to the MLlib decision tree. It also adds sample weights support using WeightedLabeledPoint class for handling unbalanced datasets during classification. It will also support algorithms such as AdaBoost which requires instances to be weighted. It handles the special case where the categorical variables cannot be ordered for multiclass classification and thus the optimizations used for speeding up binary classification cannot be directly used for multiclass classification with categorical variables. More specifically, for m categories in a categorical feature, it analyses all the ```2^(m-1) - 1``` categorical splits provided that #splits are less than the maxBins provided in the input. This condition will not be met for features with large number of categories -- using decision trees is not recommended for such datasets in general since the categorical features are favored over continuous features. Moreover, the user can use a combination of tricks (increasing bin size of the tree algorithms, use binary encoding for categorical features or use one-vs-all classification strategy) to avoid these constraints. The new code is accompanied by unit tests and has also been tested on the iris and covtype datasets. cc: mengxr, etrain, hirakendu, atalwalkar, srowen Author: Manish Amde <manish9ue@gmail.com> Author: manishamde <manish9ue@gmail.com> Author: Evan Sparks <sparks@cs.berkeley.edu> Closes apache#886 from manishamde/multiclass and squashes the following commits: 26f8acc [Manish Amde] another attempt at fixing mima c5b2d04 [Manish Amde] more MIMA fixes 1ce7212 [Manish Amde] change problem filter for mima 10fdd82 [Manish Amde] fixing MIMA excludes e1c970d [Manish Amde] merged master abf2901 [Manish Amde] adding classes to MimaExcludes.scala 45e767a [Manish Amde] adding developer api annotation for overriden methods c8428c4 [Manish Amde] fixing weird multiline bug afced16 [Manish Amde] removed label weights support 2d85a48 [Manish Amde] minor: fixed scalastyle issues reprise 4e85f2c [Manish Amde] minor: fixed scalastyle issues b2ae41f [Manish Amde] minor: scalastyle e4c1321 [Manish Amde] using while loop for regression histograms d75ac32 [Manish Amde] removed WeightedLabeledPoint from this PR 0fecd38 [Manish Amde] minor: add newline to EOF 2061cf5 [Manish Amde] merged from master 06b1690 [Manish Amde] fixed off-by-one error in bin to split conversion 9cc3e31 [Manish Amde] added implicit conversion import 5c1b2ca [Manish Amde] doc for PointConverter class 485eaae [Manish Amde] implicit conversion from LabeledPoint to WeightedLabeledPoint 3d7f911 [Manish Amde] updated doc 8e44ab8 [Manish Amde] updated doc adc7315 [Manish Amde] support ordered categorical splits for multiclass classification e3e8843 [Manish Amde] minor code formatting 23d4268 [Manish Amde] minor: another minor code style 34ee7b9 [Manish Amde] minor: code style 237762d [Manish Amde] renaming functions 12e6d0a [Manish Amde] minor: removing line in doc 9a90c93 [Manish Amde] Merge branch 'master' into multiclass 1892a2c [Manish Amde] tests and use multiclass binaggregate length when atleast one categorical feature is present f5f6b83 [Manish Amde] multiclass for continous variables 8cfd3b6 [Manish Amde] working for categorical multiclass classification 828ff16 [Manish Amde] added categorical variable test bce835f [Manish Amde] code cleanup 7e5f08c [Manish Amde] minor doc 1dd2735 [Manish Amde] bin search logic for multiclass f16a9bb [Manish Amde] fixing while loop d811425 [Manish Amde] multiclass bin aggregate logic ab5cb21 [Manish Amde] multiclass logic d8e4a11 [Manish Amde] sample weights ed5a2df [Manish Amde] fixed classification requirements d012be7 [Manish Amde] fixed while loop 18d2835 [Manish Amde] changing default values for num classes 6b912dc [Manish Amde] added numclasses to tree runner, predict logic for multiclass, add multiclass option to train 75f2bfc [Manish Amde] minor code style fix e547151 [Manish Amde] minor modifications 34549d0 [Manish Amde] fixing error during merge 098e8c5 [Manish Amde] merged master e006f9d [Manish Amde] changing variable names 5c78e1a [Manish Amde] added multiclass support 6c7af22 [Manish Amde] prepared for multiclass without breaking binary classification 46e06ee [Manish Amde] minor mods 3f85a17 [Manish Amde] tests for multiclass classification 4d5f70c [Manish Amde] added multiclass support for find splits bins 46f909c [Manish Amde] todo for multiclass support 455bea9 [Manish Amde] fixed tests 14aea48 [Manish Amde] changing instance format to weighted labeled point a1a6e09 [Manish Amde] added weighted point class 968ca9d [Manish Amde] merged master 7fc9545 [Manish Amde] added docs ce004a1 [Manish Amde] minor formatting b27ad2c [Manish Amde] formatting 426bb28 [Manish Amde] programming guide blurb 8053fed [Manish Amde] more formatting 5eca9e4 [Manish Amde] grammar 4731cda [Manish Amde] formatting 5e82202 [Manish Amde] added documentation, fixed off by 1 error in max level calculation cbd9f14 [Manish Amde] modified scala.math to math dad9652 [Manish Amde] removed unused imports e0426ee [Manish Amde] renamed parameter 718506b [Manish Amde] added unit test 1517155 [Manish Amde] updated documentation 9dbdabe [Manish Amde] merge from master 719d009 [Manish Amde] updating user documentation fecf89a [manishamde] Merge pull request alteryx#6 from etrain/deep_tree 0287772 [Evan Sparks] Fixing scalastyle issue. 2f1e093 [Manish Amde] minor: added doc for maxMemory parameter 2f6072c [manishamde] Merge pull request alteryx#5 from etrain/deep_tree abc5a23 [Evan Sparks] Parameterizing max memory. 50b143a [Manish Amde] adding support for very deep trees

I'm fine with cleaning up any remaining PEP 8 violations as part of this pull request. * I did not understand why the RAT and scalastyle reports are saved to text files. I did the same for the PEP 8 check, but only so that the console output style can match those for the RAT and scalastyle checks.

This pull requests integrates SparkR, an R frontend for Spark. The SparkR package contains both RDD and DataFrame APIs in R and is integrated with Spark's submission scripts to work on different cluster managers. Some integration points that would be great to get feedback on: 1. Build procedure: SparkR requires R to be installed on the machine to be built. Right now we have a new Maven profile `-PsparkR` that can be used to enable SparkR builds 2. YARN cluster mode: The R package that is built needs to be present on the driver and all the worker nodes during execution. The R package location is currently set using SPARK_HOME, but this might not work on YARN cluster mode. The SparkR package represents the work of many contributors and attached below is a list of people along with areas they worked on edwardt (edwart) - Documentation improvements Felix Cheung (felixcheung) - Documentation improvements Hossein Falaki (falaki) - Documentation improvements Chris Freeman (cafreeman) - DataFrame API, Programming Guide Todd Gao (7c00) - R worker Internals Ryan Hafen (hafen) - SparkR Internals Qian Huang (hqzizania) - RDD API Hao Lin (hlin09) - RDD API, Closure cleaner Evert Lammerts (evertlammerts) - DataFrame API Davies Liu (davies) - DataFrame API, R worker internals, Merging with Spark Yi Lu (lythesia) - RDD API, Worker internals Matt Massie (massie) - Jenkins build Harihar Nahak (hnahak87) - SparkR examples Oscar Olmedo (oscaroboto) - Spark configuration Antonio Piccolboni (piccolbo) - SparkR examples, Namespace bug fixes Dan Putler (dputler) - Dataframe API, SparkR Install Guide Ashutosh Raina (ashutoshraina) - Build improvements Josh Rosen (joshrosen) - Travis CI build Sun Rui (sun-rui)- RDD API, JVM Backend, Shuffle improvements Shivaram Venkataraman (shivaram) - RDD API, JVM Backend, Worker Internals Zongheng Yang (concretevitamin) - RDD API, Pipelined RDDs, Examples and EC2 guide Author: Shivaram Venkataraman <shivaram@cs.berkeley.edu> Author: Shivaram Venkataraman <shivaram.venkataraman@gmail.com> Author: Zongheng Yang <zongheng.y@gmail.com> Author: cafreeman <cfreeman@alteryx.com> Author: Shivaram Venkataraman <shivaram@eecs.berkeley.edu> Author: Davies Liu <davies@databricks.com> Author: Davies Liu <davies.liu@gmail.com> Author: hlin09 <hlin09pu@gmail.com> Author: Sun Rui <rui.sun@intel.com> Author: lythesia <iranaikimi@gmail.com> Author: oscaroboto <oscarjr@gmail.com> Author: Antonio Piccolboni <antonio@piccolboni.info> Author: root <edward> Author: edwardt <edwardt.tril@gmail.com> Author: hqzizania <qian.huang@intel.com> Author: dputler <dan.putler@gmail.com> Author: Todd Gao <todd.gao.2013@gmail.com> Author: Chris Freeman <cfreeman@alteryx.com> Author: Felix Cheung <fcheung@AVVOMAC-119.local> Author: Hossein <hossein@databricks.com> Author: Evert Lammerts <evert@apache.org> Author: Felix Cheung <fcheung@avvomac-119.t-mobile.com> Author: felixcheung <felixcheung_m@hotmail.com> Author: Ryan Hafen <rhafen@gmail.com> Author: Ashutosh Raina <ashutoshraina@users.noreply.github.com> Author: Oscar Olmedo <oscarjr@gmail.com> Author: Josh Rosen <rosenville@gmail.com> Author: Yi Lu <iranaikimi@gmail.com> Author: Harihar Nahak <hnahak87@users.noreply.github.com> Closes #5096 from shivaram/R and squashes the following commits: da64742 [Davies Liu] fix Date serialization 59266d1 [Davies Liu] check exclusive of primary-py-file and primary-r-file 55808e4 [Davies Liu] fix tests 5581c75 [Davies Liu] update author of SparkR f731b48 [Shivaram Venkataraman] Only run SparkR tests if R is installed 64eda24 [Shivaram Venkataraman] Merge branch 'R' of https://github.com/amplab-extras/spark into R d7c3f22 [Shivaram Venkataraman] Address code review comments Changes include 1.

This PR move codegen implementation of expressions into Expression class itself, make it easy to manage. It introduces two APIs in Expression: ``` def gen(ctx: CodeGenContext): GeneratedExpressionCode def genCode(ctx: CodeGenContext, ev: GeneratedExpressionCode): Code ``` gen(ctx) will call genSource(ctx, ev) to generate Java source code for the current expression. A expression needs to override genSource(). Here are the types: ``` type Term String type Code String /** * Java source for evaluating an [[Expression]] given a [[Row]] of input. */ case class GeneratedExpressionCode(var code: Code, nullTerm: Term, primitiveTerm: Term, objectTerm: Term) /** * A context for codegen, which is used to bookkeeping the expressions those are not supported * by codegen, then they are evaluated directly. The unsupported expression is appended at the * end of `references`, the position of it is kept in the code, used to access and evaluate it. */ class CodeGenContext { /** * Holding all the expressions those do not support codegen, will be evaluated directly. */ val references: Seq[Expression] = new mutable.ArrayBuffer[Expression]() } ``` This is basically apache#6660, but fixed style violation and compilation failure.

## What changes were proposed in this pull request? Implements `eval()` method for expression `AssertNotNull` so that we can convert local projection on LocalRelation to another LocalRelation. ### Before change: ``` scala> import org.apache.spark.sql.catalyst.dsl.expressions._ scala> import org.apache.spark.sql.catalyst.expressions.objects.AssertNotNull scala> import org.apache.spark.sql.Column scala> case class A(a: Int) scala> Seq((A(1),2)).toDS().select(new Column(AssertNotNull("_1".attr, Nil))).explain java.lang.UnsupportedOperationException: Only code-generated evaluation is supported. at org.apache.spark.sql.catalyst.expressions.objects.AssertNotNull.eval(objects.scala:850) ... ``` ### After the change: ``` scala> Seq((A(1),2)).toDS().select(new Column(AssertNotNull("_1".attr, Nil))).explain(true) == Parsed Logical Plan == 'Project [assertnotnull('_1) AS assertnotnull(_1)alteryx#5] +- LocalRelation [_1#2, _2#3] == Analyzed Logical Plan == assertnotnull(_1): struct<a:int> Project [assertnotnull(_1#2) AS assertnotnull(_1)alteryx#5] +- LocalRelation [_1#2, _2#3] == Optimized Logical Plan == LocalRelation [assertnotnull(_1)alteryx#5] == Physical Plan == LocalTableScan [assertnotnull(_1)alteryx#5] ``` ## How was this patch tested?
