Total tasks in the aggregated table and the tasks table are not matching some times in the WEBUI.
We need to force update the executor summary of the particular executorId, when ever last task of that executor has reached. Currently it force update based on last task on the stage end. So, for some particular executorId task might miss at the stage end.
Tests to reproduce:
```
bin/spark-shell --master yarn --conf spark.executor.instances=3
sc.parallelize(1 to 10000, 10).map{ x => throw new RuntimeException("Bad executor")}.collect()
```

Closes#23038 from shahidki31/SPARK-25451.

Support column sort, pagination and search for Stage Page using jQuery DataTable and REST API. Before this commit, the Stage page generated a hard-coded HTML table that could not support search. Supporting search and sort (over all applications rather than the 20 entries in the current page) in any case will greatly improve the user experience.
Created the stagespage-template.html for displaying application information in datables. Added REST api endpoint and javascript code to fetch data from the endpoint and display it on the data table.
Because of the above change, certain functionalities in the page had to be modified to support the addition of datatables. For example, the toggle checkbox 'Select All' previously would add the checked fields as columns in the Task table and as rows in the Summary Metrics table, but after the change, only columns are added in the Task Table as it got tricky to add rows dynamically in the datatables.
## How was this patch tested?
I have attached the screenshots of the Stage Page UI before and after the fix.

## What changes were proposed in this pull request?
SparkSQL doesn't support to encode `Option[Product]` as a top-level row now, because in SparkSQL entire top-level row can't be null.
However for use cases like Aggregator, it is reasonable to use `Option[Product]` as buffer and output column types. Due to above limitation, we don't do it for now.
This patch proposes to encode `Option[Product]` at top-level as single struct column. So we can work around the issue that entire top-level row can't be null.
To summarize encoding of `Product` and `Option[Product]`.
For `Product`, 1. at root level, the schema is all fields are flatten it into multiple columns. The `Product ` can't be null, otherwise it throws an exception.
```scala
val df = Seq((1 -> "a"), (2 -> "b")).toDF()
df.printSchema()
root
|-- _1: integer (nullable = false)
|-- _2: string (nullable = true)
```
2. At non-root level, `Product` is a struct type column.
```scala
val df = Seq((1, (1 -> "a")), (2, (2 -> "b")), (3, null)).toDF()
df.printSchema()
root
|-- _1: integer (nullable = false)
|-- _2: struct (nullable = true)
| |-- _1: integer (nullable = false)
| |-- _2: string (nullable = true)
```
For `Option[Product]`, 1. it was not supported at root level. After this change, it is a struct type column.
```scala
val df = Seq(Some(1 -> "a"), Some(2 -> "b"), None).toDF()
df.printSchema
root
|-- value: struct (nullable = true)
| |-- _1: integer (nullable = false)
| |-- _2: string (nullable = true)
```
2. At non-root level, it is also a struct type column.
```scala
val df = Seq((1, Some(1 -> "a")), (2, Some(2 -> "b")), (3, None)).toDF()
df.printSchema
root
|-- _1: integer (nullable = false)
|-- _2: struct (nullable = true)
| |-- _1: integer (nullable = false)
| |-- _2: string (nullable = true)
```
3. For use case like Aggregator, it was not supported too. After this change, we support to use `Option[Product]` as buffer/output column type.
```scala
val df = Seq(
OptionBooleanIntData("bob", Some((true, 1))),
OptionBooleanIntData("bob", Some((false, 2))),
OptionBooleanIntData("bob", None)).toDF()
val group = df
.groupBy("name")
.agg(OptionBooleanIntAggregator("isGood").toColumn.alias("isGood"))
group.printSchema
root
|-- name: string (nullable = true)
|-- isGood: struct (nullable = true)
| |-- _1: boolean (nullable = false)
| |-- _2: integer (nullable = false)
```
The buffer and output type of `OptionBooleanIntAggregator` is both `Option[(Boolean, Int)`.

This patch defines an internal Spark interface for reporting shuffle metrics and uses that in shuffle reader. Before this patch, shuffle metrics is tied to a specific implementation (using a thread local temporary data structure and accumulators). After this patch, callers that define their own shuffle RDDs can create a custom metrics implementation.
With this patch, we would be able to create a better metrics for the SQL layer, e.g. reporting shuffle metrics in the SQL UI, for each exchange operator.
Note that I'm separating read side and write side implementations, as they are very different, to simplify code review. Write side change is at https://github.com/apache/spark/pull/23106

This is a followup of #23099 . After upgrading to Kafka 2.1.0, maven test fails due to Zookeeper test dependency while sbt test succeeds.

The root cause is that the embedded Kafka server is using [Zookeepr 3.4.7 API](https://zookeeper.apache.org/doc/r3.4.7/api/org/apache/zookeeper/AsyncCallback.MultiCallback.html
) while Apache Spark provides Zookeeper 3.4.6. This PR adds a test dependency.

## What changes were proposed in this pull request?
An input without valid JSON tokens on the root level will be treated as a bad record, and handled according to `mode`. Previously such input was converted to `null`. After the changes, the input is converted to a row with `null`s in the `PERMISSIVE` mode according the schema. This allows to remove a code in the `from_json` function which can produce `null` as result rows.
## How was this patch tested?
It was tested by existing test suites. Some of them I have to modify (`JsonSuite` for example) because previously bad input was just silently ignored. For now such input is handled according to specified `mode`.

bin/docker-image-tool.sh tries to build all docker images (JVM, PySpark
and SparkR) by default. But not all spark distributions are built with
SparkR and hence this script will fail on such distros.
With this change, we make building alternate language binding docker images (PySpark and SparkR) optional. User has to specify dockerfile for those language bindings using -p and -R flags accordingly, to build the binding docker images.
## How was this patch tested?
Tested following scenarios.
*bin/docker-image-tool.sh -r <repo> -t <tag> build* --> Builds only JVM docker image (default behavior)
*bin/docker-image-tool.sh -r <repo> -t <tag> -p kubernetes/dockerfiles/spark/bindings/python/Dockerfile build* --> Builds both JVM and PySpark docker images
*bin/docker-image-tool.sh -r <repo> -t <tag> -p kubernetes/dockerfiles/spark/bindings/python/Dockerfile -R kubernetes/dockerfiles/spark/bindings/R/Dockerfile build* --> Builds JVM, PySpark and SparkR docker images.

In the PR, I propose:
- new SQL config `spark.sql.debug.maxToStringFields` to control maximum number fields up to which `truncatedString` cuts its input sequences.
- Moving `truncatedString` out of `core` to `sql/catalyst` because it is used only in the `sql/catalyst` packages for restricting number of fields converted to strings from `TreeNode` and expressions of`StructType`.
## How was this patch tested?
Added a test to `QueryExecutionSuite` to check that `spark.sql.debug.maxToStringFields` impacts to behavior of `truncatedString`.

## What changes were proposed in this pull request?
This change fixes a particular scenario where default spark SQL can't encode (thrift) types that are generated by twitter scrooge. These types are a trait that extends `scala.ProductX` with a constructor defined only in a companion object, rather than a actual case class. The actual case class used is child class, but that type is almost never referred to in code. The type has no corresponding constructor symbol and causes an exception. For all other purposes, these classes act just like case classes, so it is unfortunate that spark SQL can't serialize them nicely as it can actual case classes. For an full example of a scrooge codegen class, see https://gist.github.com/anonymous/ba13d4b612396ca72725eaa989900314.
This change catches the case where the type has no constructor but does have an `apply` method on the type's companion object. This allows for thrift types to be serialized/deserialized with implicit encoders the same way as normal case classes. This fix had to be done in three places where the constructor is assumed to be an actual constructor:
1) In serializing, determining the schema for the dataframe relies on inspecting its constructor (`ScalaReflection.constructParams`). Here we fall back to using the companion constructor arguments.
2) In deserializing or evaluating, in the java codegen ( `NewInstance.doGenCode`), the type couldn't be constructed with the new keyword. If there is no constructor, we change the constructor call to try the companion constructor.
3) In deserializing or evaluating, without codegen, the constructor is directly invoked (`NewInstance.constructor`). This was fixed with scala reflection to get the actual companion apply method.
The return type of `findConstructor` was changed because the companion apply method constructor can't be represented as a `java.lang.reflect.Constructor`.
There might be situations in which this approach would also fail in a new way, but it does at a minimum work for the specific scrooge example and will not impact cases that were already succeeding prior to this change
Note: this fix does not enable using scrooge thrift enums, additional work for this is necessary. With this patch, it seems like you could patch `com.twitter.scrooge.ThriftEnum` to extend `_root_.scala.Product1[Int]` with `def _1 = value` to get spark's implicit encoders to handle enums, but I've yet to use this method myself.
Note: I previously opened a PR for this issue, but only was able to fix case 1) there: https://github.com/apache/spark/pull/18766
## How was this patch tested?
I've fixed all 3 cases and added two tests that use a case class that is similar to scrooge generated one. The test in ScalaReflectionSuite checks 1), and the additional asserting in ObjectExpressionsSuite checks 2) and 3).

## 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.

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).

$ printf 'A%.0s' {1..9500} >> cookie
# HTTP GET with huge header fails with 431
$ curl -H cookie http://458apiros-MBP.lan:18080/
<h1>Bad Message 431</h1><pre>reason: Request Header Fields Too Large</pre>
# The log contains the error

When I try to run scripts (e.g. `start-master.sh`/`start-history-server.sh ` in latest master, I got such error:
```
Presence of build for multiple Scala versions detected.
Either clean one of them or, export SPARK_SCALA_VERSION in spark-env.sh.
```
The error message is quite confusing. Without reading `load-spark-env.sh`, I didn't know which directory to remove, or where to find and edit the `spark-evn.sh`.
This PR is to make the error message more clear. Also change the script for less maintenance when we add or drop Scala versions in the future.
As now with https://github.com/apache/spark/pull/22967, we can revise the error message as following(in my local setup):
```
Presence of build for multiple Scala versions detected (/Users/gengliangwang/IdeaProjects/spark/assembly/target/scala-2.12 and /Users/gengliangwang/IdeaProjects/spark/assembly/target/scala-2.11).
Remove one of them or, export SPARK_SCALA_VERSION=2.12 in /Users/gengliangwang/IdeaProjects/spark/conf/spark-env.sh.

## What changes were proposed in this pull request?
Extend the `ReplaceNullWithFalse` optimizer rule introduced in SPARK-25860 (https://github.com/apache/spark/pull/22857) to also support optimizing predicates in higher-order functions of `ArrayExists`, `ArrayFilter`, `MapFilter`.
Also rename the rule to `ReplaceNullWithFalseInPredicate` to better reflect its intent.
Example:
```sql
select filter(a, e -> if(e is null, null, true)) as b from (
select array(null, 1, null, 3) as a)
```
The optimized logical plan:
**Before**:
```
== Optimized Logical Plan ==
Project [filter([null,1,null,3], lambdafunction(if (isnull(lambda e#13)) null else true, lambda e#13, false)) AS b#9]
+- OneRowRelation
```
**After**:
```
== Optimized Logical Plan ==
Project [filter([null,1,null,3], lambdafunction(if (isnull(lambda e#13)) false else true, lambda e#13, false)) AS b#9]
+- OneRowRelation
```
