This PR adds a debugging log for YARN-specific credential providers which is loaded by service loader mechanism.
It took me a while to debug if it's actually loaded or not. I had to explicitly set the deprecated configuration and check if that's actually being loaded.
The change scope is manually tested. Logs are like:
```
Using the following builtin delegation token providers: hadoopfs, hive, hbase.
Using the following YARN-specific credential providers: yarn-test.
```

This change takes into account all non-pending tasks when calculating
the number of tasks to be shown. This also means that when the stage
is pending, the task table (or, in fact, most of the data in the stage
page) will not be rendered.
I also fixed the label when the known number of tasks is larger than
the recorded number of tasks (it was inverted).

When two `In` operators are created with the same list of values, but different order, we are considering them as semantically different. This is wrong, since they have the same semantic meaning.
The PR adds a canonicalization rule which orders the literals in the `In` operator so the semantic equality works properly.

In client side before context initialization specifically, .py file doesn't work in client side before context initialization when the application is a Python file. See below:
```
$ cat /home/spark/tmp.py
def testtest():
return 1
```
This works:
```
$ cat app.py
import pyspark
pyspark.sql.SparkSession.builder.getOrCreate()
import tmp
print("************************%s" % tmp.testtest())
$ ./bin/spark-submit --master yarn --deploy-mode client --py-files /home/spark/tmp.py app.py
...
************************1
```
but this doesn't:
```
$ cat app.py
import pyspark
import tmp
pyspark.sql.SparkSession.builder.getOrCreate()
print("************************%s" % tmp.testtest())
$ ./bin/spark-submit --master yarn --deploy-mode client --py-files /home/spark/tmp.py app.py
Traceback (most recent call last):
File "/home/spark/spark/app.py", line 2, in <module>
import tmp
ImportError: No module named tmp
```
### How did it happen?
In client mode specifically, the paths are being added into PythonRunner as are:
628c7b5179/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala (L430)628c7b5179/core/src/main/scala/org/apache/spark/deploy/PythonRunner.scala (L49-L88)
The problem here is, .py file shouldn't be added as are since `PYTHONPATH` expects a directory or an archive like zip or egg.
### How does this PR fix?
We shouldn't simply just add its parent directory because other files in the parent directory could also be added into the `PYTHONPATH` in client mode before context initialization.
Therefore, we copy .py files into a temp directory for .py files and add it to `PYTHONPATH`.
## How was this patch tested?
Unit tests are added and manually tested in both standalond and yarn client modes with submit.

## What changes were proposed in this pull request?
This pr fixed an issue when having multiple distinct aggregations having the same argument set, e.g.,
```
scala>: paste
val df = sql(
s"""SELECT corr(DISTINCT x, y), corr(DISTINCT y, x), count(*)
| FROM (VALUES (1, 1), (2, 2), (2, 2)) t(x, y)
""".stripMargin)
java.lang.RuntimeException
You hit a query analyzer bug. Please report your query to Spark user mailing list.
```
The root cause is that `RewriteDistinctAggregates` can't detect multiple distinct aggregations if they have the same argument set. This pr modified code so that `RewriteDistinctAggregates` could count the number of aggregate expressions with `isDistinct=true`.

Make sure that `StopIteration`s raised in users' code do not silently interrupt processing by spark, but are raised as exceptions to the users. The users' functions are wrapped in `safe_iter` (in `shuffle.py`), which re-raises `StopIteration`s as `RuntimeError`s
## How was this patch tested?
Unit tests, making sure that the exceptions are indeed raised. I am not sure how to check whether a `Py4JJavaError` contains my exception, so I simply looked for the exception message in the java exception's `toString`. Can you propose a better way?

For some Spark applications, though they're a java program, they require not only jar dependencies, but also python dependencies. One example is Livy remote SparkContext application, this application is actually an embedded REPL for Scala/Python/R, it will not only load in jar dependencies, but also python and R deps, so we should specify not only "--jars", but also "--py-files".
Currently for a Spark application, --py-files can only be worked for a pyspark application, so it will not be worked in the above case. So here propose to remove such restriction.
Also we tested that "spark.submit.pyFiles" only supports quite limited scenario (client mode with local deps), so here also expand the usage of "spark.submit.pyFiles" to be alternative of --py-files.

## What changes were proposed in this pull request?
When we create a `RelationalGroupedDataset` or a `KeyValueGroupedDataset` we set its child to the `logicalPlan` of the `DataFrame` we need to aggregate. Since the `logicalPlan` is already analyzed, we should not analyze it again. But this happens when the new plan of the aggregate is analyzed.
The current behavior in most of the cases is likely to produce no harm, but in other cases re-analyzing an analyzed plan can change it, since the analysis is not idempotent. This can cause issues like the one described in the JIRA (missing to find a cached plan).
The PR adds an `AnalysisBarrier` to the `logicalPlan` which is used as child of `RelationalGroupedDataset` or a `KeyValueGroupedDataset`.

There is a race condition of closing Arrow VectorSchemaRoot and Allocator in the writer thread of ArrowPythonRunner.
The race results in memory leak exception when closing the allocator. This patch removes the closing routine from the TaskCompletionListener and make the writer thread responsible for cleaning up the Arrow memory.
This issue be reproduced by this test:
```
def test_memory_leak(self):
from pyspark.sql.functions import pandas_udf, col, PandasUDFType, array, lit, explode
# Have all data in a single executor thread so it can trigger the race condition easier
with self.sql_conf({'spark.sql.shuffle.partitions': 1}):
df = self.spark.range(0, 1000)
df = df.withColumn('id', array([lit(i) for i in range(0, 300)])) \
.withColumn('id', explode(col('id'))) \
.withColumn('v', array([lit(i) for i in range(0, 1000)]))
pandas_udf(df.schema, PandasUDFType.GROUPED_MAP)
def foo(pdf):
xxx
return pdf
result = df.groupby('id').apply(foo)
with QuietTest(self.sc):
with self.assertRaises(py4j.protocol.Py4JJavaError) as context:
result.count()
self.assertTrue('Memory leaked' not in str(context.exception))
```
Note: Because of the race condition, the test case cannot reproduce the issue reliably so it's not added to test cases.
## How was this patch tested?
Because of the race condition, the bug cannot be unit test easily. So far it has only happens on large amount of data. This is currently tested manually.

uniVocity parser allows to specify only required column names or indexes for [parsing](https://www.univocity.com/pages/parsers-tutorial) like:
```
// Here we select only the columns by their indexes.
// The parser just skips the values in other columns
parserSettings.selectIndexes(4, 0, 1);
CsvParser parser = new CsvParser(parserSettings);
```
In this PR, I propose to extract indexes from required schema and pass them into the CSV parser. Benchmarks show the following improvements in parsing of 1000 columns:
```
Select 100 columns out of 1000: x1.76
Select 1 column out of 1000: x2
```
**Note**: Comparing to current implementation, the changes can return different result for malformed rows in the `DROPMALFORMED` and `FAILFAST` modes if only subset of all columns is requested. To have previous behavior, set `spark.sql.csv.parser.columnPruning.enabled` to `false`.
## How was this patch tested?

ORC 1.4.4 includes [nine fixes](https://issues.apache.org/jira/issues/?filter=12342568&jql=project%20%3D%20ORC%20AND%20resolution%20%3D%20Fixed%20AND%20fixVersion%20%3D%201.4.4). One of the issues is about `Timestamp` bug (ORC-306) which occurs when `native` ORC vectorized reader reads ORC column vector's sub-vector `times` and `nanos`. ORC-306 fixes this according to the [original definition](https://github.com/apache/hive/blob/master/storage-api/src/java/org/apache/hadoop/hive/ql/exec/vector/TimestampColumnVector.java#L45-L46) and this PR includes the updated interpretation on ORC column vectors. Note that `hive` ORC reader and ORC MR reader is not affected.
```scala
scala> spark.version
res0: String = 2.3.0
scala> spark.sql("set spark.sql.orc.impl=native")
scala> Seq(java.sql.Timestamp.valueOf("1900-05-05 12:34:56.000789")).toDF().write.orc("/tmp/orc")
scala> spark.read.orc("/tmp/orc").show(false)

LongToUnsafeRowMap has a mistake when growing its page array: it blindly grows to `oldSize * 2`, while the new record may be larger than `oldSize * 2`. Then we may have a malformed UnsafeRow when querying this map, whose actual data is smaller than its declared size, and the data is corrupted.

### Fixes `ClassCastException` in the `array_position` function - [SPARK-24350](https://issues.apache.org/jira/browse/SPARK-24350)
When calling `array_position` function with a wrong type of the 1st argument an `AnalysisException` should be thrown instead of `ClassCastException`
Example:
```sql
select array_position('foo', 'bar')
```
```
java.lang.ClassCastException: org.apache.spark.sql.types.StringType$ cannot be cast to org.apache.spark.sql.types.ArrayType

## What changes were proposed in this pull request?
Add a specific stop method for ContinuousExecution. The previous StreamExecution.stop() method had a race condition as applied to continuous processing: if the cancellation was round-tripped to the driver too quickly, the generic SparkException it caused would be reported as the query death cause. We earlier decided that SparkException should not be added to the StreamExecution.isInterruptionException() whitelist, so we need to ensure this never happens instead.
## How was this patch tested?
Existing tests. I could consistently reproduce the previous flakiness by putting Thread.sleep(1000) between the first job cancellation and thread interruption in StreamExecution.stop().

`CachedKafkaConsumer` in the project streaming-kafka-0-10 is designed to maintain a pool of KafkaConsumers that can be reused. However, it was built with the assumption there will be only one thread trying to read the same Kafka TopicPartition at the same time. This assumption is not true all the time and this can inadvertently lead to ConcurrentModificationException.
Here is a better way to design this. The consumer pool should be smart enough to avoid concurrent use of a cached consumer. If there is another request for the same TopicPartition as a currently in-use consumer, the pool should automatically return a fresh consumer.
- There are effectively two kinds of consumer that may be generated
- Cached consumer - this should be returned to the pool at task end
- Non-cached consumer - this should be closed at task end
- A trait called `KafkaDataConsumer` is introduced to hide this difference from the users of the consumer so that the client code does not have to reason about whether to stop and release. They simply call `val consumer = KafkaDataConsumer.acquire` and then `consumer.release`.
- If there is request for a consumer that is in-use, then a new consumer is generated.
- If there is request for a consumer which is a task reattempt, then already existing cached consumer will be invalidated and a new consumer is generated. This could fix potential issues if the source of the reattempt is a malfunctioning consumer.
- In addition, I renamed the `CachedKafkaConsumer` class to `KafkaDataConsumer` because is a misnomer given that what it returns may or may not be cached.
## How was this patch tested?
A new stress test that verifies it is safe to concurrently get consumers for the same TopicPartition from the consumer pool.
