"DataFrameCallbackSuite.execute callback functions when a DataFrame action failed" sets the log level to "fatal" but doesn't recover it. Hence, tests running after it won't output any logs except fatal logs.
This PR uses `testQuietly` instead to avoid changing the log level.

[SPARK-19617](https://issues.apache.org/jira/browse/SPARK-19617) changed `HDFSMetadataLog` to enable interrupts when using the local file system. However, now we hit [HADOOP-12074](https://issues.apache.org/jira/browse/HADOOP-12074): `Shell.runCommand` converts `InterruptedException` to `new IOException(ie.toString())` before Hadoop 2.8. This is the Hadoop patch to fix HADOOP-1207: 95c73d49b1
This PR adds new logic to handle the following cases related to `InterruptedException`.
- Check if the message of IOException starts with `java.lang.InterruptedException`. If so, treat it as `InterruptedException`. This is for pre-Hadoop 2.8.
- Treat `InterruptedIOException` as `InterruptedException`. This is for Hadoop 2.8+ and other places that may throw `InterruptedIOException` when the thread is interrupted.

This is a follow-up pr of #16308 and #16750.
This pr enables timezone support in partition values.
We should use `timeZone` option introduced at #16750 to parse/format partition values of the `TimestampType`.
For example, if you have timestamp `"2016-01-01 00:00:00"` in `GMT` which will be used for partition values, the values written by the default timezone option, which is `"GMT"` because the session local timezone is `"GMT"` here, are:
```scala
scala> spark.conf.set("spark.sql.session.timeZone", "GMT")
scala> val df = Seq((1, new java.sql.Timestamp(1451606400000L))).toDF("i", "ts")
df: org.apache.spark.sql.DataFrame = [i: int, ts: timestamp]
scala> df.show()
+---+-------------------+
| i| ts|
+---+-------------------+
| 1|2016-01-01 00:00:00|
+---+-------------------+
scala> df.write.partitionBy("ts").save("/path/to/gmtpartition")
```
```sh
$ ls /path/to/gmtpartition/
_SUCCESS ts=2016-01-01 00%3A00%3A00
```
whereas setting the option to `"PST"`, they are:
```scala
scala> df.write.option("timeZone", "PST").partitionBy("ts").save("/path/to/pstpartition")
```
```sh
$ ls /path/to/pstpartition/
_SUCCESS ts=2015-12-31 16%3A00%3A00
```
We can properly read the partition values if the session local timezone and the timezone of the partition values are the same:
```scala
scala> spark.read.load("/path/to/gmtpartition").show()
+---+-------------------+
| i| ts|
+---+-------------------+
| 1|2016-01-01 00:00:00|
+---+-------------------+
```
And even if the timezones are different, we can properly read the values with setting corrent timezone option:
```scala
// wrong result
scala> spark.read.load("/path/to/pstpartition").show()
+---+-------------------+
| i| ts|
+---+-------------------+
| 1|2015-12-31 16:00:00|
+---+-------------------+
// correct result
scala> spark.read.option("timeZone", "PST").load("/path/to/pstpartition").show()
+---+-------------------+
| i| ts|
+---+-------------------+
| 1|2016-01-01 00:00:00|
+---+-------------------+

When we resolve inline tables in analyzer, we will evaluate the expressions of inline tables.
When it evaluates a `TimeZoneAwareExpression` expression, an error will happen because the `TimeZoneAwareExpression` is not associated with timezone yet.
So we need to resolve these `TimeZoneAwareExpression`s with time zone when resolving inline tables.

```
while hive table is ok ,so we should fix it for datasource table.
The reason is that the SaveMode check is put in `InsertIntoHadoopFsRelationCommand` , and the SaveMode check actually use `path`, this is fine when we use `DataFrameWriter.save()`, because this situation of SaveMode act on `path`.
While when we use `CreateDataSourceAsSelectCommand`, the situation of SaveMode act on table, and
we have already do SaveMode check in `CreateDataSourceAsSelectCommand` for table , so we should not do SaveMode check in the following logic in `InsertIntoHadoopFsRelationCommand` for path, this is redundant and wrong logic for `CreateDataSourceAsSelectCommand`
After this PR, the following DDL will succeed, when the location has been created we will append it or overwrite it.
```

## What changes were proposed in this pull request?
Right now file source always uses `InMemoryFileIndex` to scan files from a given path.
But when reading the outputs from another streaming query, the file source should use `MetadataFileIndex` to list files from the sink log. This patch adds this support.
## `MetadataFileIndex` or `InMemoryFileIndex`
```scala
spark
.readStream
.format(...)
.load("/some/path") // for a non-glob path:
// - use `MetadataFileIndex` when `/some/path/_spark_meta` exists
// - fall back to `InMemoryFileIndex` otherwise
```
```scala
spark
.readStream
.format(...)
.load("/some/path/*/*") // for a glob path: always use `InMemoryFileIndex`

This PR proposes the support for multiple lines for CSV by resembling the multiline supports in JSON datasource (in case of JSON, per file).
So, this PR introduces `wholeFile` option which makes the format not splittable and reads each whole file. Since Univocity parser can produces each row from a stream, it should be capable of parsing very large documents when the internal rows are fix in the memory.

## What changes were proposed in this pull request?
HDFSBackedStateStoreProvider fails to rename files on HDFS but not on the local filesystem. According to the [implementation notes](https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/filesystem/filesystem.html) of `rename()`, the behavior of the local filesystem and HDFS varies:
> Destination exists and is a file
> Renaming a file atop an existing file is specified as failing, raising an exception.
> - Local FileSystem : the rename succeeds; the destination file is replaced by the source file.
> - HDFS : The rename fails, no exception is raised. Instead the method call simply returns false.
This patch ensures that `rename()` isn't called if the destination file already exists. It's still semantically correct because Structured Streaming requires that rerunning a batch should generate the same output.

If we refresh a InMemoryFileIndex with a FileStatusCache, it will first use the FileStatusCache to re-generate the cachedLeafFiles etc, then call FileStatusCache.invalidateAll.

```
override def refresh(): Unit = {
refresh0()
fileStatusCache.invalidateAll()

val files = listLeafFiles(rootPaths)

currently if multiple streaming queries listeners exists, when a QueryTerminatedEvent is triggered, only one of the listeners will be invoked while the rest of the listeners will ignore the event.
this is caused since the the streaming queries listeners bus holds a set of running queries ids and when a termination event is triggered, after the first listeners is handling the event, the terminated query id is being removed from the set.
in this PR, the query id will be removed from the set only after all the listeners handles the event

After adding the tests for subquery, we now have multiple level of directories under "sql-tests/inputs". Some times on Mac while using Finder application it creates the meta data files called ".DS_Store". When these files are present at different levels in directory hierarchy, we get duplicate test exception while running the tests as we just use the file name as the test case name. In this PR, we use the relative file path from the base directory along with the test file as the test name. Also after this change, we can have the same test file name under different directory like exists/basic.sql , in/basic.sql. Here is the truncated output of the test run after the change.

Spark executes SQL commands eagerly. It does this by creating an RDD which contains the command's results. The downside to this is that any action on this RDD triggers a Spark job which is expensive and is unnecessary.
This PR fixes this by avoiding the materialization of an `RDD` for `Command`s; it just materializes the result and puts them in a `LocalRelation`.
Added a regression test to `SQLQuerySuite`.

Currently we can only check the estimated stats in logical plans by debugging. We need to provide an easier and more efficient way for developers/users.
In this pr, we add EXPLAIN COST command to show stats in the optimized logical plan.
E.g.
```
spark-sql> EXPLAIN COST select count(1) from store_returns;
...
== Optimized Logical Plan ==
Aggregate [count(1) AS count(1)#24L], Statistics(sizeInBytes=16.0 B, rowCount=1, isBroadcastable=false)
+- Project, Statistics(sizeInBytes=4.3 GB, rowCount=5.76E+8, isBroadcastable=false)
+- Relation[sr_returned_date_sk#3,sr_return_time_sk#4,sr_item_sk#5,sr_customer_sk#6,sr_cdemo_sk#7,sr_hdemo_sk#8,sr_addr_sk#9,sr_store_sk#10,sr_reason_sk#11,sr_ticket_number#12,sr_return_quantity#13,sr_return_amt#14,sr_return_tax#15,sr_return_amt_inc_tax#16,sr_fee#17,sr_return_ship_cost#18,sr_refunded_cash#19,sr_reversed_charge#20,sr_store_credit#21,sr_net_loss#22] parquet, Statistics(sizeInBytes=28.6 GB, rowCount=5.76E+8, isBroadcastable=false)

In [SPARK-15959](https://issues.apache.org/jira/browse/SPARK-15959), we bring back the `hive.metastore.warehouse.dir` , while in the logic, when use the value of `spark.sql.warehouse.dir` to overwrite `hive.metastore.warehouse.dir` , it set it to `sparkContext.conf` which does not overwrite the value is hadoopConf, I think it should put in `sparkContext.hadoopConfiguration` and overwrite the original value of hadoopConf

This pr added a logic to put malformed tokens into a new field when parsing CSV data in case of permissive modes. In the current master, if the CSV parser hits these malformed ones, it throws an exception below (and then a job fails);
```

In case that users load large CSV-formatted data, the job failure makes users get some confused. So, this fix set NULL for original columns and put malformed tokens in a new field.

## What changes were proposed in this pull request?
This PR adds a special streaming deduplication operator to support `dropDuplicates` with `aggregation` and watermark. It reuses the `dropDuplicates` API but creates new logical plan `Deduplication` and new physical plan `DeduplicationExec`.
The following cases are supported:
- one or multiple `dropDuplicates()` without aggregation (with or without watermark)
- `dropDuplicates` before aggregation
Not supported cases:
- `dropDuplicates` after aggregation
Breaking changes:
- `dropDuplicates` without aggregation doesn't work with `complete` or `update` mode.

## What changes were proposed in this pull request?
SPARK-15615 proposes replacing the sqlContext.read.json(rdd) with a dataset equivalent.
SPARK-15463 adds a CSV API for reading from Dataset[String] so this keeps the API consistent.
I am deprecating the existing RDD based APIs.
## How was this patch tested?
There are existing tests. I left most tests to use the existing APIs as they delegate to the new json API.

Currently, if `NumPartitions` is not set in RepartitionByExpression, we will set it using `spark.sql.shuffle.partitions` during Planner. However, this is not following the general resolution process. This PR is to set it in `Parser` and then `Optimizer` can use the value for plan optimization.

## What changes were proposed in this pull request?
To ease debugging, most of Spark SQL internals have public level visibility. Two of the most important internal states, sharedState and sessionState, however, are package private. It would make more sense to open these up as well with clear documentation that they are internal.
In addition, users currently have way to set active/default SparkSession, but no way to actually get them back. We should open those up as well.

## What changes were proposed in this pull request?
In `FileFormatWriter`, we will sort the input rows by partition columns and bucket id and sort columns, if we want to write data out partitioned or bucketed.
However, if the data is already sorted, we will sort it again, which is unnecssary.
This PR removes the sorting logic in `FileFormatWriter` and use `SortExec` instead. We will not add `SortExec` if the data is already sorted.
## How was this patch tested?
I did a micro benchmark manually
```
val df = spark.range(10000000).select($"id", $"id" % 10 as "part").sort("part")
spark.time(df.write.partitionBy("part").parquet("/tmp/test"))
```
The result was about 6.4 seconds before this PR, and is 5.7 seconds afterwards.

`askSync` is already added in `RpcEndpointRef` (see SPARK-19347 and https://github.com/apache/spark/pull/16690#issuecomment-276850068) and `askWithRetry` is marked as deprecated.
As mentioned SPARK-18113(https://github.com/apache/spark/pull/16503#event-927953218):
>askWithRetry is basically an unneeded API, and a leftover from the akka days that doesn't make sense anymore. It's prone to cause deadlocks (exactly because it's blocking), it imposes restrictions on the caller (e.g. idempotency) and other things that people generally don't pay that much attention to when using it.
Since `askWithRetry` is just used inside spark and not in user logic. It might make sense to replace all of them with `askSync`.

## What changes were proposed in this pull request?
The streaming thread in StreamExecution uses the following ways to check if it should exit:
- Catch an InterruptException.
- `StreamExecution.state` is TERMINATED.
When starting and stopping a query quickly, the above two checks may both fail:
- Hit [HADOOP-14084](https://issues.apache.org/jira/browse/HADOOP-14084) and swallow InterruptException
- StreamExecution.stop is called before `state` becomes `ACTIVE`. Then [runBatches](dcc2d540a5/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/StreamExecution.scala (L252)) changes the state from `TERMINATED` to `ACTIVE`.
If the above cases both happen, the query will hang forever.
This PR changes `state` to `AtomicReference` and uses`compareAndSet` to make sure we only change the state from `INITIALIZING` to `ACTIVE`. It also removes the `runUninterruptibly` hack from ``HDFSMetadata`, because HADOOP-14084 won't cause any problem after we fix the race condition.
