### What changes were proposed in this pull request?
This PR proposes to match the test with branch-2.4. See https://github.com/apache/spark/pull/25593#discussion_r318109047
Seems using `SparkSession.builder` with Spark conf possibly affects other tests.
### Why are the changes needed?
To match with branch-2.4 and to make easier to backport.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Test was fixed.

### What changes were proposed in this pull request?
Introduce ANSI store assignment policy for table insertion.
With ANSI policy, Spark performs the type coercion of table insertion as per ANSI SQL.
### Why are the changes needed?
In Spark version 2.4 and earlier, when inserting into a table, Spark will cast the data type of input query to the data type of target table by coercion. This can be super confusing, e.g. users make a mistake and write string values to an int column.
In data source V2, by default, only upcasting is allowed when inserting data into a table. E.g. int -> long and int -> string are allowed, while decimal -> double or long -> int are not allowed. The rules of UpCast was originally created for Dataset type coercion. They are quite strict and different from the behavior of all existing popular DBMS. This is breaking change. It is possible that existing queries are broken after 3.0 releases.
Following ANSI SQL standard makes Spark consistent with the table insertion behaviors of popular DBMS like PostgreSQL/Oracle/Mysql.
### Does this PR introduce any user-facing change?
A new optional mode for table insertion.
### How was this patch tested?

### What changes were proposed in this pull request?
Make `spark.sql.crossJoin.enabled` default value true
### Why are the changes needed?
For implicit cross join, we can set up a watchdog to cancel it if running for a long time.
When "spark.sql.crossJoin.enabled" is false, because `CheckCartesianProducts` is implemented in logical plan stage, it may generate some mismatching error which may confuse end user:
* it's done in logical phase, so we may fail queries that can be executed via broadcast join, which is very fast.
* if we move the check to the physical phase, then a query may success at the beginning, and begin to fail when the table size gets larger (other people insert data to the table). This can be quite confusing.
* the CROSS JOIN syntax doesn't work well if join reorder happens.
* some non-equi-join will generate plan using cartesian product, but `CheckCartesianProducts` do not detect it and raise error.
So that in order to address this in simpler way, we can turn off showing this cross-join error by default.
For reference, I list some cases raising mismatching error here:
Providing:
```
spark.range(2).createOrReplaceTempView("sm1") // can be broadcast
spark.range(50000000).createOrReplaceTempView("bg1") // cannot be broadcast
spark.range(60000000).createOrReplaceTempView("bg2") // cannot be broadcast
```
1) Some join could be convert to broadcast nested loop join, but CheckCartesianProducts raise error. e.g.
```
select sm1.id, bg1.id from bg1 join sm1 where sm1.id < bg1.id
```
2) Some join will run by CartesianJoin but CheckCartesianProducts DO NOT raise error. e.g.
```
select bg1.id, bg2.id from bg1 join bg2 where bg1.id < bg2.id
```

## What changes were proposed in this pull request?
Currently we have 2 configs to specify which v2 sources should fallback to v1 code path. One config for read path, and one config for write path.
However, I found it's awkward to work with these 2 configs:
1. for `CREATE TABLE USING format`, should this be read path or write path?
2. for `V2SessionCatalog.loadTable`, we need to return `UnresolvedTable` if it's a DS v1 or we need to fallback to v1 code path. However, at that time, we don't know if the returned table will be used for read or write.
We don't have any new features or perf improvement in file source v2. The fallback API is just a safeguard if we have bugs in v2 implementations. There are not many benefits to support falling back to v1 for read and write path separately.
This PR proposes to merge these 2 configs into one.

### What changes were proposed in this pull request?
During graceful shutdown of ``StreamingContext`` ``graph.stop()`` is invoked right after stopping of ``timer`` which generates new job. Thus it's possible that the latest jobs generated by timer are still in the middle of generation but invocation of ``graph.stop()`` closes some objects required to job generation, e.g. consumer for Kafka, and generation fails. That also leads to fully waiting of ``spark.streaming.gracefulStopTimeout`` which is equal to 10 batch intervals by default. Stopping of the graph should be performed later, after ``haveAllBatchesBeenProcessed`` is completed.
### How was this patch tested?
Added test to existing test suite.

## What changes were proposed in this pull request?
The shuffle writer API introduced in SPARK-28209 has a flaw that leads to a memory usage regression - we ended up tracking the partition lengths in two places. Here, we modify the API slightly to avoid redundant tracking. The implementation of the shuffle writer plugin is now responsible for tracking the lengths of partitions, and propagating this back up to the higher shuffle writer as part of the commitAllPartitions API.

In my application spark streaming is restarted programmatically by stopping StreamingContext without stopping of SparkContext and creating/starting a new one. I use it for automatic detection of Kafka topic/partition changes and automatic failover in case of non fatal exceptions.
However i notice that after multiple restarts driver fails with OOM. During investigation of heap dump i figured out that StreamingContext object isn't cleared by GC after stopping.

There are several places which holds reference to it :
1. StreamingTab registers StreamingJobProgressListener which holds reference to Streaming Context directly to LiveListenerBus shared queue via ssc.sc.addSparkListener(listener) method invocation. However this listener isn't unregistered at stop method.
2. json handlers (/streaming/json and /streaming/batch/json) aren't unregistered in SparkUI, while they hold reference to StreamingJobProgressListener. Basically the same issue affects all the pages, i assume that renderJsonHandler should be added to pageToHandlers cache on attachPage method invocation in order to unregistered it as well on detachPage.
3. SparkUi holds reference to StreamingJobProgressListener in the corresponding local variable which isn't cleared after stopping of StreamingContext.
## How was this patch tested?
Added tests to existing test suites.
After i applied these changes via reflection in my app OOM on driver side gone.

## What changes were proposed in this pull request?
This PR aims at improving the way physical plans are explained in spark.
Currently, the explain output for physical plan may look very cluttered and each operator's
string representation can be very wide and wraps around in the display making it little
hard to follow. This especially happens when explaining a query 1) Operating on wide tables
2) Has complex expressions etc.
This PR attempts to split the output into two sections. In the header section, we display
the basic operator tree with a number associated with each operator. In this section, we strictly
control what we output for each operator. In the footer section, each operator is verbosely
displayed. Based on the feedback from Maryann, the uncorrelated subqueries (SubqueryExecs) are not included in the main plan. They are printed separately after the main plan and can be
correlated by the originating expression id from its parent plan.
To illustrate, here is a simple plan displayed in old vs new way.

```
EXPLAIN SELECT key, Max(val) FROM explain_temp1 WHERE key > 0 GROUP BY key HAVING max(val) > 0

Resolves [SPARK-28778: Shuffle jobs fail due to incorrect advertised address when running in a virtual network on Mesos](https://issues.apache.org/jira/browse/SPARK-28778).
This patch fixes a bug which occurs when shuffle jobs are launched by Mesos in a virtual network. Mesos scheduler sets executor `--hostname` parameter to `0.0.0.0` in the case when `spark.mesos.network.name` is provided. This makes executors use `0.0.0.0` as their advertised address and, in the presence of shuffle, executors fail to fetch shuffle blocks from each other using `0.0.0.0` as the origin. When a virtual network is used the hostname or IP address is not known upfront and assigned to a container at its start time so the executor process needs to advertise the correct dynamically assigned address to be reachable by other executors.
Changes:
- added a fallback to `Utils.localHostName()` in Spark Executors when `--hostname` is not provided
- removed setting executor address to `0.0.0.0` from Mesos scheduler
- refactored the code related to building executor command in Mesos scheduler
- added network configuration support to Docker containerizer
- added unit tests
### Why are the changes needed?
The bug described above prevents Mesos users from running any jobs which involve shuffle due to the inability of executors to fetch shuffle blocks because of incorrect advertised address when virtual network is used.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
- added unit test to `MesosCoarseGrainedSchedulerBackendSuite` which verifies the absence of `--hostname` parameter when `spark.mesos.network.name` is provided and its presence otherwise
- added unit test to `MesosSchedulerBackendUtilSuite` which verifies that `MesosSchedulerBackendUtil.buildContainerInfo` sets network-related properties for Docker containerizer
- unit tests from this repo launched with profiles: `./build/mvn test -Pmesos -Pnetlib-lgpl -Psparkr -Phive -Phive-thriftserver`, build log attached: [mvn.test.log](https://github.com/apache/spark/files/3516891/mvn.test.log)
- integration tests from [DCOS Spark repo](https://github.com/mesosphere/spark-build), more specifically - [test_spark_cni.py](https://github.com/mesosphere/spark-build/blob/master/tests/test_spark_cni.py) which runs a specific [shuffle job](https://github.com/mesosphere/spark-build/blob/master/tests/jobs/scala/src/main/scala/ShuffleApp.scala) and verifies its successful completion, Mesos task network configuration, and IP addresses for both Mesos and Docker containerizers

To follow ANSI SQL, we should support a configurable mode that throws exceptions when casting to integers causes overflow.
The behavior is similar to https://issues.apache.org/jira/browse/SPARK-26218, which throws exceptions on arithmetical operation overflow.
To unify it, the configuration is renamed from "spark.sql.arithmeticOperations.failOnOverFlow" to "spark.sql.failOnIntegerOverFlow"

### What changes were proposed in this pull request?
This PR fixes the leak of crc files from CheckpointFileManager when FileContextBasedCheckpointFileManager is being used.
Spark hits the Hadoop bug, [HADOOP-16255](https://issues.apache.org/jira/browse/HADOOP-16255) which seems to be a long-standing issue.
This is there're two `renameInternal` methods:
```
public void renameInternal(Path src, Path dst)
public void renameInternal(final Path src, final Path dst, boolean overwrite)
```
which should be overridden to handle all cases but ChecksumFs only overrides method with 2 params, so when latter is called FilterFs.renameInternal(...) is called instead, and it will do rename with RawLocalFs as underlying filesystem.
The bug is related to FileContext, so FileSystemBasedCheckpointFileManager is not affected.
[SPARK-17475](https://issues.apache.org/jira/browse/SPARK-17475) took a workaround for this bug, but [SPARK-23966](https://issues.apache.org/jira/browse/SPARK-23966) seemed to bring regression.
This PR deletes crc file as "best-effort" when renaming, as failing to delete crc file is not that critical to fail the task.
### Why are the changes needed?
This PR prevents crc files not being cleaned up even purging batches. Too many files in same directory often hurts performance, as well as each crc file occupies more space than its own size so possible to occupy nontrivial amount of space when batches go up to 100000+.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Some unit tests are modified to check leakage of crc files.

## What changes were proposed in this pull request?
After all the discussions in the dev list: http://apache-spark-developers-list.1001551.n3.nabble.com/Discuss-Follow-ANSI-SQL-on-table-insertion-td27531.html#a27562.
Here I propose that we can make the store assignment rules in the analyzer configurable, and the behavior of V1 and V2 should be consistent.
When inserting a value into a column with a different data type, Spark will perform type coercion. After this PR, we support 2 policies for the type coercion rules:
legacy and strict.
1. With legacy policy, Spark allows casting any value to any data type. The legacy policy is the only behavior in Spark 2.x and it is compatible with Hive.
2. With strict policy, Spark doesn't allow any possible precision loss or data truncation in type coercion, e.g. `int` and `long`, `float` -> `double` are not allowed.
Eventually, the "legacy" mode will be removed, so it is disallowed in data source V2.
To ensure backward compatibility with existing queries, the default store assignment policy for data source V1 is "legacy".

### What changes were proposed in this pull request?
Spark uses Netty 4 directly, but also includes Netty 3 only because transitive dependencies do. The dependencies (Hadoop HDFS, Zookeeper, Avro) don't seem to need this dependency as used in Spark. I think we can forcibly remove it to slim down the dependencies.
Previous attempts were blocked by its usage in Flume, but that dependency has gone away.
https://github.com/apache/spark/pull/15436
### Why are the changes needed?
Mostly to reduce the transitive dependency size and complexity a little bit and avoid triggering spurious security alerts on Netty 3.x usage.
