This PR lets stage color change with it's status. The main idea is to make css style class name match the corresponding stage status.

How was this patch tested?

Manually tested locally.

// active/complete stage

* [SPARK-25837][CORE] Fix potential slowdown in AppStatusListener when cleaning up stages

## What changes were proposed in this pull request?

* Update `AppStatusListener` `cleanupStages` method to remove tasks for those stages in a single pass instead of 1 for each stage.
* This fixes an issue where the cleanupStages method would get backed up, causing a backup in the executor in ElementTrackingStore, resulting in stages and jobs not getting cleaned up properly.

Tasks seem most susceptible to this as there are a lot of them, however a similar issue could arise in other locations the `KVStore` `view` method is used. A broader fix might involve updates to `KVStoreView` and `InMemoryView` as it appears this interface and implementation can lead to multiple and inefficient traversals of the stored data.

## How was this patch tested?

This is my original work and I license the work to the project under the project’s open source license.

* [SPARK-26011][SPARK-SUBMIT] Yarn mode pyspark app without python main resource does not honor "spark.jars.packages"

SparkSubmit determines pyspark app by the suffix of primary resource but Livy
uses "spark-internal" as the primary resource when calling spark-submit,
therefore args.isPython is set to false in SparkSubmit.scala.

In Yarn mode, SparkSubmit module is responsible for resolving maven coordinates
and adding them to "spark.submit.pyFiles" so that python's system path can be set correctly.

The fix is to resolve maven coordinates not only when args.isPython is true,
but also when primary resource is spark-internal.

Tested the patch with Livy submitting pyspark app, spark-submit, pyspark with or without packages config.

* [MINOR][SQL] Fix typo in CTAS plan database string

## What changes were proposed in this pull request?

Since [Spark 1.6.0](apache@56d7da1#diff-6f38a103058a6e233b7ad80718452387R96), there was a redundant '}' character in CTAS string plan's database argument string; `default}`. This PR aims to fix it.

**BEFORE**
```scala
scala> sc.version
res1: String = 1.6.0

scala> sql("create table t as select 1").explain
== Physical Plan ==
ExecutedCommand CreateTableAsSelect [Database:default}, TableName: t, InsertIntoHiveTable]
+- Project [1 AS _c0#3]
   +- OneRowRelation$
```

**AFTER**
```scala
scala> sql("create table t as select 1").explain

+- *(1) Project [1 AS 1#4]

* [SPARK-26084][SQL] Fixes unresolved AggregateExpression.references exception

## What changes were proposed in this pull request?

This PR fixes an exception in `AggregateExpression.references` called on unresolved expressions. It implements the solution proposed in [SPARK-26084](https://issues.apache.org/jira/browse/SPARK-26084), a minor refactoring that removes the unnecessary dependence on `AttributeSet.toSeq`, which requires expression IDs and, therefore, can only execute successfully for resolved expressions.

The refactored implementation is both simpler and faster, eliminating the conversion of a `Set` to a
`Seq` and back to `Set`.

## How was this patch tested?

Added a new test based on the failing case in [SPARK-26084](https://issues.apache.org/jira/browse/SPARK-26084).

* [SPARK-26109][WEBUI] Duration in the task summary metrics table and the task table are different

## What changes were proposed in this pull request?
Task summary table displays the summary of the task table in the stage page. However, the 'Duration' metrics of 'task summary' table and 'task table' are not matching. The reason is because, in the 'task summary' we display 'executorRunTime' as the duration, and in the 'task table' the actual duration of the task. Except duration metrics, all other metrics are properly displaying in the task summary.

In Spark2.2, used to show 'executorRunTime' as duration in the 'taskTable'. That is why, in summary metrics also the 'exeuctorRunTime' shows as the duration. So, we need to show 'executorRunTime' as the duration in the tasks table to follow the same behaviour as the previous versions of spark.

* [SPARK-26233][SQL][BACKPORT-2.3] CheckOverflow when encoding a decimal value

## What changes were proposed in this pull request?

When we encode a Decimal from external source we don't check for overflow. That method is useful not only in order to enforce that we can represent the correct value in the specified range, but it also changes the underlying data to the right precision/scale. Since in our code generation we assume that a decimal has exactly the same precision and scale of its data type, missing to enforce it can lead to corrupted output/results when there are subsequent transformations.

* [SPARK-26352][SQL] join reorder should not change the order of output attributes

## What changes were proposed in this pull request?

The optimizer rule `org.apache.spark.sql.catalyst.optimizer.ReorderJoin` performs join reordering on inner joins. This was introduced from SPARK-12032 (apache#10073) in 2015-12.

After it had reordered the joins, though, it didn't check whether or not the output attribute order is still the same as before. Thus, it's possible to have a mismatch between the reordered output attributes order vs the schema that a DataFrame thinks it has.
The same problem exists in the CBO version of join reordering (`CostBasedJoinReorder`) too.

This can be demonstrated with the example:
```scala
spark.sql("create table table_a (x int, y int) using parquet")
spark.sql("create table table_b (i int, j int) using parquet")
spark.sql("create table table_c (a int, b int) using parquet")
val df = spark.sql("""
  with df1 as (select * from table_a cross join table_b)
  select * from df1 join table_c on a = x and b = i
""")
```
here's what the DataFrame thinks:
```
scala> df.printSchema
root
 |-- x: integer (nullable = true)
 |-- y: integer (nullable = true)
 |-- i: integer (nullable = true)
 |-- j: integer (nullable = true)
 |-- a: integer (nullable = true)
 |-- b: integer (nullable = true)
```
here's what the optimized plan thinks, after join reordering:
```
scala> df.queryExecution.optimizedPlan.output.foreach(a => println(s"|-- ${a.name}: ${a.dataType.typeName}"))
|-- x: integer
|-- y: integer
|-- a: integer
|-- b: integer
|-- i: integer
|-- j: integer
```

If we exclude the `ReorderJoin` rule (using Spark 2.4's optimizer rule exclusion feature), it's back to normal:
```
scala> spark.conf.set("spark.sql.optimizer.excludedRules", "org.apache.spark.sql.catalyst.optimizer.ReorderJoin")

scala> val df = spark.sql("with df1 as (select * from table_a cross join table_b) select * from df1 join table_c on a = x and b = i")
df: org.apache.spark.sql.DataFrame = [x: int, y: int ... 4 more fields]

scala> df.queryExecution.optimizedPlan.output.foreach(a => println(s"|-- ${a.name}: ${a.dataType.typeName}"))
|-- x: integer
|-- y: integer
|-- i: integer
|-- j: integer
|-- a: integer
|-- b: integer
```

Note that this output attribute ordering problem leads to data corruption, and can manifest itself in various symptoms:
* Silently corrupting data, if the reordered columns happen to either have matching types or have sufficiently-compatible types (e.g. all fixed length primitive types are considered as "sufficiently compatible" in an `UnsafeRow`), then only the resulting data is going to be wrong but it might not trigger any alarms immediately. Or
* Weird Java-level exceptions like `java.lang.NegativeArraySizeException`, or even SIGSEGVs.

## How was this patch tested?

Added new unit test in `JoinReorderSuite` and new end-to-end test in `JoinSuite`.
Also made `JoinReorderSuite` and `StarJoinReorderSuite` assert more strongly on maintaining output attribute order.

* [SPARK-26422][R] Support to disable Hive support in SparkR even for Hadoop versions unsupported by Hive fork

## What changes were proposed in this pull request?

Currently,  even if I explicitly disable Hive support in SparkR session as below:

```r
sparkSession <- sparkR.session("local[4]", "SparkR", Sys.getenv("SPARK_HOME"),
                               enableHiveSupport = FALSE)
```

produces when the Hadoop version is not supported by our Hive fork:

```
java.lang.reflect.InvocationTargetException
...

	at org.apache.spark.sql.api.r.SQLUtils.getOrCreateSparkSession(SQLUtils.scala)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
```

The root cause is that:

```
SparkSession.hiveClassesArePresent
```

check if the class is loadable or not to check if that's in classpath but `org.apache.hadoop.hive.conf.HiveConf` has a check for Hadoop version as static logic which is executed right away. This throws an `IllegalArgumentException` and that's not caught:

https://github.com/apache/spark/blob/36edbac1c8337a4719f90e4abd58d38738b2e1fb/sql/core/src/main/scala/org/apache/spark/sql/SparkSession.scala#L1113-L1121

So, currently, if users have a Hive built-in Spark with unsupported Hadoop version by our fork (namely 3+), there's no way to use SparkR even though it could work.

This PR just propose to change the order of bool comparison so that we can don't execute `SparkSession.hiveClassesArePresent` when:

  1. `enableHiveSupport` is explicitly disabled
  2. `spark.sql.catalogImplementation` is `in-memory`

so that we **only** check `SparkSession.hiveClassesArePresent` when Hive support is explicitly enabled by short circuiting.

## How was this patch tested?

It's difficult to write a test since we don't run tests against Hadoop 3 yet. See apache#21588. Manually tested.

* [SPARK-26366][SQL][BACKPORT-2.3] ReplaceExceptWithFilter should consider NULL as False

## What changes were proposed in this pull request?

In `ReplaceExceptWithFilter` we do not consider properly the case in which the condition returns NULL. Indeed, in that case, since negating NULL still returns NULL, so it is not true the assumption that negating the condition returns all the rows which didn't satisfy it, rows returning NULL may not be returned. This happens when constraints inferred by `InferFiltersFromConstraints` are not enough, as it happens with `OR` conditions.

The rule had also problems with non-deterministic conditions: in such a scenario, this rule would change the probability of the output.

The PR fixes these problem by:
 - returning False for the condition when it is Null (in this way we do return all the rows which didn't satisfy it);
 - avoiding any transformation when the condition is non-deterministic.

* [SPARK-26019][PYSPARK] Allow insecure py4j gateways

Spark always creates secure py4j connections between java and python,
but it also allows users to pass in their own connection.  This restores
the ability for users to pass in an _insecure_ connection, though it
forces them to set the env variable 'PYSPARK_ALLOW_INSECURE_GATEWAY=1', and still
issues a warning.

Added test cases verifying the failure without the extra configuration,
and verifying things still work with an insecure configuration (in
particular, accumulators, as those were broken with an insecure py4j
gateway before).

For the tests, I added ways to create insecure gateways, but I tried to put in protections to make sure that wouldn't get used incorrectly.

Closes apache#23337 from squito/SPARK-26019.

When there is a self-join as result of a IN subquery, the join condition may be invalid, resulting in trivially true predicates and return wrong results.

This PR lets stage color change with it's status. The main idea is to make css style class name match the corresponding stage status.

Manually tested locally.
