Fixes --packages flag for the stand-alone case in cluster mode. Adds to the driver classpath the jars that are resolved via ivy along with any other jars passed to `spark.jars`. Jars not resolved by ivy are downloaded explicitly to a tmp folder on the driver node. Similar code is available in SparkSubmit so we refactored part of it to use it at the DriverWrapper class which is responsible for launching driver in standalone cluster mode.
Note: In stand-alone mode `spark.jars` contains the user jar so it can be fetched later on at the executor side.

[SPARK-21595](https://issues.apache.org/jira/browse/SPARK-21595) reported that there is excessive spilling to disk due to default spill threshold for `ExternalAppendOnlyUnsafeRowArray` being quite small for WINDOW operator. Old behaviour of WINDOW operator (pre https://github.com/apache/spark/pull/16909) would hold data in an array for first 4096 records post which it would switch to `UnsafeExternalSorter` and start spilling to disk after reaching `spark.shuffle.spill.numElementsForceSpillThreshold` (or earlier if there was paucity of memory due to excessive consumers).
Currently the (switch from in-memory to `UnsafeExternalSorter`) and (`UnsafeExternalSorter` spilling to disk) for `ExternalAppendOnlyUnsafeRowArray` is controlled by a single threshold. This PR aims to separate that to have more granular control.

Add an option to the JDBC data source to initialize the environment of the remote database session
## What changes were proposed in this pull request?
This proposes an option to the JDBC datasource, tentatively called " sessionInitStatement" to implement the functionality of session initialization present for example in the Sqoop connector for Oracle (see https://sqoop.apache.org/docs/1.4.6/SqoopUserGuide.html#_oraoop_oracle_session_initialization_statements ) . After each database session is opened to the remote DB, and before starting to read data, this option executes a custom SQL statement (or a PL/SQL block in the case of Oracle).

When train RF model, there are many warning messages like this:
> WARN RandomForest: Tree learning is using approximately 268492800 bytes per iteration, which exceeds requested limit maxMemoryUsage=268435456. This allows splitting 2622 nodes in this iteration.
This warning message is unnecessary and the data is not accurate.
Actually, if all the nodes cannot split in one iteration, it will show this warning. For most of the case, all the nodes cannot split just in one iteration, so for most of the case, it will show this warning for each iteration.

## What changes were proposed in this pull request?
This patch introduces an internal interface for tracking metrics and/or statistics on data on the fly, as it is being written to disk during a `FileFormatWriter` job and partially reimplements SPARK-20703 in terms of it.
The interface basically consists of 3 traits:
- `WriteTaskStats`: just a tag for classes that represent statistics collected during a `WriteTask`
The only constraint it adds is that the class should be `Serializable`, as instances of it will be collected on the driver from all executors at the end of the `WriteJob`.
- `WriteTaskStatsTracker`: a trait for classes that can actually compute statistics based on tuples that are processed by a given `WriteTask` and eventually produce a `WriteTaskStats` instance.
- `WriteJobStatsTracker`: a trait for classes that act as containers of `Serializable` state that's necessary for instantiating `WriteTaskStatsTracker` on executors and finally process the resulting collection of `WriteTaskStats`, once they're gathered back on the driver.
Potential future use of this interface is e.g. CBO stats maintenance during `INSERT INTO table ... ` operations.

## What changes were proposed in this pull request?
Currently `df.na.replace("*", Map[String, String]("NULL" -> null))` will produce exception.
This PR enables passing null/None as value in the replacement map in DataFrame.replace().
Note that the replacement map keys and values should still be the same type, while the values can have a mix of null/None and that type.
This PR enables following operations for example:
`df.na.replace("*", Map[String, String]("NULL" -> null))`(scala)
`df.na.replace("*", Map[Any, Any](60 -> null, 70 -> 80))`(scala)
`df.na.replace('Alice', None)`(python)
`df.na.replace([10, 20])`(python, replacing with None is by default)
One use case could be: I want to replace all the empty strings with null/None because they were incorrectly generated and then drop all null/None data
`df.na.replace("*", Map("" -> null)).na.drop()`(scala)
`df.replace(u'', None).dropna()`(python)

This pr updated `lz4-java` to the latest (v1.4.0) and removed custom `LZ4BlockInputStream`. We currently use custom `LZ4BlockInputStream` to read concatenated byte stream in shuffle. But, this functionality has been implemented in the latest lz4-java (https://github.com/lz4/lz4-java/pull/105). So, we might update the latest to remove the custom `LZ4BlockInputStream`.
Major diffs between the latest release and v1.3.0 in the master are as follows (62f7547abb...6d4693f562);
- fixed NPE in XXHashFactory similarly
- Don't place resources in default package to support shading
- Fixes ByteBuffer methods failing to apply arrayOffset() for array-backed
- Try to load lz4-java from java.library.path, then fallback to bundled
- Add ppc64le binary
- Add s390x JNI binding
- Add basic LZ4 Frame v1.5.0 support
- enable aarch64 support for lz4-java
- Allow unsafeInstance() for ppc64le archiecture
- Add unsafeInstance support for AArch64
- Support 64-bit JNI build on Solaris
- Avoid over-allocating a buffer
- Allow EndMark to be incompressible for LZ4FrameInputStream.

Currently, each application and each worker creates their own proxy servlet. Each proxy servlet is backed by its own HTTP client and a relatively large number of selector threads. This is excessive but was fixed (to an extent) by https://github.com/apache/spark/pull/18437.
However, a single HTTP client (backed by a single selector thread) should be enough to handle all proxy requests. This PR creates a single proxy servlet no matter how many applications and workers there are.

The executor tab on Spark UI page shows task as completed when an executor process that is running that task is killed using the kill command.

When I was investigating a flaky test, I realized that many places don't check the return value of `HDFSMetadataLog.get(batchId: Long): Option[T]`. When a batch is supposed to be there, the caller just ignores None rather than throwing an error. If some bug causes a query doesn't generate a batch metadata file, this behavior will hide it and allow the query continuing to run and finally delete metadata logs and make it hard to debug.
This PR ensures that places calling HDFSMetadataLog.get always check the return value.

This PR proposes to use https://rversions.r-pkg.org/r-release-win instead of https://rversions.r-pkg.org/r-release to check R's version for Windows correctly.
We met a syncing problem with Windows release (see #15709) before. To cut this short, it was ...
- 3.3.2 release was released but not for Windows for few hours.
- `https://rversions.r-pkg.org/r-release` returns the latest as 3.3.2 and the download link for 3.3.1 becomes `windows/base/old` by our script
- 3.3.2 release for WIndows yet
- 3.3.1 is still not in `windows/base/old` but `windows/base` as the latest
- Failed to download with `windows/base/old` link and builds were broken
I believe this problem is not only what we met. Please see 01ce943929 and also this `r-release-win` API came out between 3.3.1 and 3.3.2 (assuming to deal with this issue), please see `https://github.com/metacran/rversions.app/issues/2`.
Using this API will prevent the problem although it looks quite rare assuming from the commit logs in https://github.com/metacran/rversions.app/commits/master. After 3.3.2, both `r-release-win` and `r-release` are being updated together.

If we create a type alias for a type workable with Dataset, the type alias doesn't work with Dataset.
A reproducible case looks like:
object C {

}
Seq(1).toDS().map(_ => ("", C.tupleTypeAlias))
It throws an exception like:
type T1 is not a class
scala.ScalaReflectionException: type T1 is not a class

Adds a sandbox link per driver in the dispatcher ui with minimal changes after a bug was fixed here:
https://issues.apache.org/jira/browse/MESOS-4992
The sandbox uri has the following format:
http://<proxy_uri>/#/slaves/\<agent-id\>/ frameworks/ \<scheduler-id\>/executors/\<driver-id\>/browse
For dc/os the proxy uri is <dc/os uri>/mesos. For the dc/os deployment scenario and to make things easier I introduced a new config property named `spark.mesos.proxy.baseURL` which should be passed to the dispatcher when launched using --conf. If no such configuration is detected then no sandbox uri is depicted, and there is an empty column with a header (this can be changed so nothing is shown).
Within dc/os the base url must be a property for the dispatcher that we should add in the future here:
9e7c909c3b/repo/packages/S/spark/26/config.json
It is not easy to detect in different environments what is that uri so user should pass it.
## How was this patch tested?
Tested with the mesos test suite here: https://github.com/typesafehub/mesos-spark-integration-tests.
Attached image shows the ui modification where the sandbox header is added.

Because when `revertPartialWritesAndClose` be called, we decrease the written records in `ShuffleWriteMetrics` . However, we decreased the written records to zero, this should be wrong, we should only decreased the number reords after the last `commitAndGet` called.

In SQLContext.get(key,null) for a key that is not defined in the conf, and doesn't have a default value defined, throws a NPE. Int happens only when conf has a value converter
Added null check on defaultValue inside SQLConf.getConfString to avoid calling entry.valueConverter(defaultValue)

## What changes were proposed in this pull request?
This PR proposes to separate `extended` into `examples` and `arguments` internally so that both can be separately documented and add `since` and `note` for additional information.
For `since`, it looks users sometimes get confused by, up to my knowledge, missing version information. For example, see https://www.mail-archive.com/userspark.apache.org/msg64798.html
For few good examples to check the built documentation, please see both:
`from_json` - https://spark-test.github.io/sparksqldoc/#from_json
`like` - https://spark-test.github.io/sparksqldoc/#like
For `DESCRIBE FUNCTION`, `note` and `since` are added as below:
```
> DESCRIBE FUNCTION EXTENDED rlike;
...
Extended Usage:
Arguments:
...
Examples:
...
Note:
Use LIKE to match with simple string pattern
```
```
> DESCRIBE FUNCTION EXTENDED to_json;
...
Examples:
...
Since: 2.2.0
```
For the complete documentation, see https://spark-test.github.io/sparksqldoc/
## How was this patch tested?
Manual tests and existing tests. Please see https://spark-test.github.io/sparksqldoc
Jenkins tests are needed to double check
