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).

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`.

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):
```

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**:

The build has a lot of deprecation warnings. Some are new in Scala 2.12 and Java 11. We've fixed some, but I wanted to take a pass at fixing lots of easy miscellaneous ones here.
They're too numerous and small to list here; see the pull request. Some highlights:
- `BeanInfo` is deprecated in 2.12, and BeanInfo classes are pretty ancient in Java. Instead, case classes can explicitly declare getters
- Eta expansion of zero-arg methods; foo() becomes () => foo() in many cases
- Floating-point Range is inexact and deprecated, like 0.0 to 100.0 by 1.0
- finalize() is finally deprecated (just needs to be suppressed)
- StageInfo.attempId was deprecated and easiest to remove here
I'm not now going to touch some chunks of deprecation warnings:
- Parquet deprecations
- Hive deprecations (particularly serde2 classes)
- Deprecations in generated code (mostly Thriftserver CLI)
- ProcessingTime deprecations (we may need to revive this class as internal)
- many MLlib deprecations because they concern methods that may be removed anyway
- a few Kinesis deprecations I couldn't figure out
- Mesos get/setRole, which I don't know well
- Kafka/ZK deprecations (e.g. poll())
- Kinesis
- a few other ones that will probably resolve by deleting a deprecated method

## What changes were proposed in this pull request?
Due to implementation limitation, currently Spark can't compare or do equality check between map types. As a result, map values can't appear in EQUAL or comparison expressions, can't be grouping key, etc.
The more important thing is, map loop up needs to do equality check of the map key, and thus can't support map as map key when looking up values from a map. Thus it's not useful to have map as map key.
This PR proposes to stop users from creating maps using map type as key. The list of expressions that are updated: `CreateMap`, `MapFromArrays`, `MapFromEntries`, `MapConcat`, `TransformKeys`. I manually checked all the places that create `MapType`, and came up with this list.
Note that, maps with map type key still exist, via reading from parquet files, converting from scala/java map, etc. This PR is not to completely forbid map as map key, but to avoid creating it by Spark itself.
Motivation: when I was trying to fix the duplicate key problem, I found it's impossible to do it with map type map key. I think it's reasonable to avoid map type map key for builtin functions.

Following [SPARK-26024](https://issues.apache.org/jira/browse/SPARK-26024), I noticed the number of elements in each partition after repartitioning using `df.repartitionByRange` can vary for the same setup:
```scala
// Shuffle numbers from 0 to 1000, and make a DataFrame
val df = Random.shuffle(0.to(1000)).toDF("val")
// Repartition it using 3 partitions
// Sum up number of elements in each partition, and collect it.
// And do it several times
for (i <- 0 to 9) {
var counts = df.repartitionByRange(3, col("val"))
.mapPartitions{part => Iterator(part.size)}
.collect()
println(counts.toList)
}
// -> the number of elements in each partition varies
```
This is expected as for performance reasons this method uses sampling to estimate the ranges (with default size of 100). Hence, the output may not be consistent, since sampling can return different values. But documentation was not mentioning it at all, leading to misunderstanding.

This restores scaladoc artifact generation, which got dropped with the Scala 2.12 update. The change looks large, but is almost all due to needing to make the InterfaceStability annotations top-level classes (i.e. `InterfaceStability.Stable` -> `Stable`), unfortunately.

Our `GBTClassifier` supports only `variance` impurity. But unfortunately, its `impurity` param by default contains the value `gini`: it is not even modifiable by the user and it differs from the actual impurity used, which is `variance`. This issue does not limit to a wrong value returned for it if the user queries by `getImpurity`, but it also affect the load of a saved model, as its `impurityStats` are created as `gini` (since this is the value stored for the model impurity) which leads to wrong `featureImportances` in model loaded from saved ones.
The PR changes the `impurity` param used to one which allows only the value `variance`.

The test failure is because `assertErrorAndClosed` misses one possible error message: `java.nio.channels.ClosedChannelException`. This happens when the second `uploadStream` is called after the channel has been closed. This can be reproduced by adding `Thread.sleep(1000)` below this line: 03306a6df3/common/network-common/src/test/java/org/apache/spark/network/RpcIntegrationSuite.java (L217)
This PR fixes the above issue and also improves the test failure messages of `assertErrorAndClosed`.

This PR breaks down the large mllib/tests.py file that contains all Python MLlib unit tests into several smaller test files to be easier to read and maintain.
The tests are broken down as follows:
```
pyspark
├── __init__.py
...
├── mllib
│ ├── __init__.py
...
│ ├── tests
│ │ ├── __init__.py
│ │ ├── test_algorithms.py
│ │ ├── test_feature.py
│ │ ├── test_linalg.py
│ │ ├── test_stat.py
│ │ ├── test_streaming_algorithms.py
│ │ └── test_util.py
...
├── testing
...
│ ├── mllibutils.py
...
```
## How was this patch tested?
Ran tests manually by module to ensure test count was the same, and ran `python/run-tests --modules=pyspark-mllib` to verify all passing with Python 2.7 and Python 3.6. Also installed scipy to include optional tests in test_linalg.

Don't propagate SPARK_CONF_DIR to the driver in mesos cluster mode.
## How was this patch tested?
I built the 2.3.2 tag with this patch added and deployed a test job to a mesos cluster to confirm that the incorrect SPARK_CONF_DIR was no longer passed from the submit command.

This is a follow-up of #20393.
We should read the conf `"spark.sql.sort.enableRadixSort"` from `SQLConf` instead of `SparkConf`, i.e., use `SQLConf.get.enableRadixSort` instead of `SparkEnv.get.conf.get(SQLConf.RADIX_SORT_ENABLED)`, otherwise the config is never read.

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.

Due to existing module dependency, I can not import spark-core in mllib-local's testsuits, so I do not add testsuite in `org.apache.spark.ml.stat.distribution.MultivariateGaussianSuite`.
And I notice that class `ClusterStats` in `ClusteringEvaluator` is registered in a different way, should it be modified to keep in line with others in ML? srowen

It's good to have annotations available at runtime, so that tools like MiMa can detect them and deal with then specially. e.g. we don't want to track compatibility for unstable classes.
This PR makes `InterfaceStability` annotations to be retained at runtime, to be consistent with `Experimental` and `DeveloperApi`

In SPARK-24865 `AnalysisBarrier` was removed and in order to improve resolution speed, the `analyzed` flag was (re-)introduced in order to process only plans which are not yet analyzed. This should not be the case when performing attribute deduplication as in that case we need to transform also the plans which were already analyzed, otherwise we can miss to rewrite some attributes leading to invalid plans.

This PR proposes to bump up the minimum versions of R from 3.1 to 3.4.
R version. 3.1.x is too old. It's released 4.5 years ago. R 3.4.0 is released 1.5 years ago. Considering the timing for Spark 3.0, deprecating lower versions, bumping up R to 3.4 might be reasonable option.
It should be good to deprecate and drop < R 3.4 support.
