KafkaContinuousSinkSuite leaks a Kafka cluster because both KafkaSourceTest and KafkaContinuousSinkSuite create a Kafka cluster but `afterAll` only shuts down one cluster. This leaks a Kafka cluster and causes that some Kafka thread crash and kill JVM when SBT is trying to clean up tests.
This PR fixes the leak and also adds a shut down hook to detect Kafka cluster leak.
In additions, it also fixes `AdminClient` leak and cleans up cached producers (When a record is writtn using a producer, the producer will keep refreshing the topic and I don't find an API to clear it except closing the producer) to eliminate the following annoying logs:
```

## What changes were proposed in this pull request?
Increment the kinesis client, producer and transient AWS SDK versions to a more recent release.
This is to help with the move off bouncy castle of #21146 and #22081; the goal is that moving up to the new SDK will allow a JVM with unlimited JCE but without bouncy castle to work with Kinesis endpoints.
Why this specific set of artifacts? it syncs up with the 1.11.271 AWS SDK used by hadoop 3.0.3, hadoop-3.1. and hadoop 3.1.1; that's been stable for the uses there (s3, STS, dynamo).
## How was this patch tested?
Running all the external/kinesis-asl tests via maven with java 8.121 & unlimited JCE, without bouncy castle (#21146); default endpoint of us-west.2. Without this SDK update I was getting http cert validation errors, with it they went away.
# This PR is not ready without
* Jenkins test runs to see what it is happy with
* more testing: repeated runs, another endpoint
* looking at the new deprecation warnings and selectively addressing them (the AWS SDKs are pretty aggressive about deprecation, but sometimes they increase the complexity of the client code or block some codepaths off completely)

This PR solves [SPARK-22713](https://issues.apache.org/jira/browse/SPARK-22713) which describes a memory leak that occurs when and ExternalAppendOnlyMap is spilled during iteration (opposed to insertion).
(Please fill in changes proposed in this fix)
ExternalAppendOnlyMap's iterator supports spilling but it kept a reference to the internal map (via an internal iterator) after spilling, it seems that the original code was actually supposed to 'get rid' of this reference on the next iteration but according to the elaborate investigation described in the JIRA this didn't happen.
the fix was simply replacing the internal iterator immediately after spilling.
## How was this patch tested?
I've introduced a new test to test suite ExternalAppendOnlyMapSuite, this test asserts that neither the external map itself nor its iterator hold any reference to the internal map after a spill.
These approach required some access relaxation of some members variables and nested classes of ExternalAppendOnlyMap, this members are now package provate and annotated with VisibleForTesting.

The PR removes a restriction for element types of array type which exists in `from_json` for the root type. Currently, the function can handle only arrays of structs. Even array of primitive types is disallowed. The PR allows arrays of any types currently supported by JSON datasource. Here is an example of an array of a primitive type:
```
scala> import org.apache.spark.sql.functions._
scala> val df = Seq("[1, 2, 3]").toDF("a")
scala> val schema = new ArrayType(IntegerType, false)
scala> val arr = df.select(from_json($"a", schema))
scala> arr.printSchema
root
|-- jsontostructs(a): array (nullable = true)
| |-- element: integer (containsNull = true)
```
and result of converting of the json string to the `ArrayType`:
```
scala> arr.show
+----------------+
|jsontostructs(a)|
+----------------+
| [1, 2, 3]|
+----------------+
```

## What changes were proposed in this pull request?
Fixing typos is sometimes very hard. It's not so easy to visually review them. Recently, I discovered a very useful tool for it, [misspell](https://github.com/client9/misspell).
This pull request fixes minor typos detected by [misspell](https://github.com/client9/misspell) except for the false positives. If you would like me to work on other files as well, let me know.

Closes#22070 from seratch/fix-typo.
Authored-by: Kazuhiro Sera <seratch@gmail.com>
Signed-off-by: Sean Owen <srowen@gmail.com>
## What changes were proposed in this pull request?
This PR add python support for barrier execution mode, thus enable launch a job containing barrier stage(s) from PySpark.
We just forked the existing `RDDBarrier` and `RDD.barrier()` in Python api.
## How was this patch tested?
Manually tested:
```
>>> rdd = sc.parallelize([1, 2, 3, 4])
>>> def f(iterator): yield sum(iterator)
...
>>> rdd.barrier().mapPartitions(f).isBarrier() == True
True
```
Unit tests will be added in a follow-up PR that implements BarrierTaskContext on python side.

## What changes were proposed in this pull request?
"distribute by" on multiple columns (wrap in brackets) may lead to codegen issue.
Simple way to reproduce:
```scala
val df = spark.range(1000)
val columns = (0 until 400).map{ i => s"id as id$i" }
val distributeExprs = (0 until 100).map(c => s"id$c").mkString(",")
df.selectExpr(columns : _*).createTempView("test")
spark.sql(s"select * from test distribute by ($distributeExprs)").count()
```
## How was this patch tested?
Add UT.
