Support 4 kinds of filters:
- LessThan
- LessThanOrEqual
- GreatThan
- GreatThanOrEqual
Support filters applied on 2 columns:
- modificationTime
- length
Note:
In order to support datasource filter push-down, I flatten schema to be:
```
val schema = StructType(
StructField("path", StringType, false) ::
StructField("modificationTime", TimestampType, false) ::
StructField("length", LongType, false) ::
StructField("content", BinaryType, true) :: Nil)
```

Because a review is resolved during analysis when we create a dataset, the content of the view is determined when the dataset is created, not when it is evaluated. Now the explain result of a dataset is not correctly consistent with the collected result of it, because we use pre-analyzed logical plan of the dataset in explain command. The explain command will analyzed the logical plan passed in. So if a view is changed after the dataset was created, the plans shown by explain command aren't the same with the plan of the dataset.
```scala
scala> spark.range(10).createOrReplaceTempView("test")
scala> spark.range(5).createOrReplaceTempView("test2")
scala> spark.sql("select * from test").createOrReplaceTempView("tmp001")
scala> val df = spark.sql("select * from tmp001")
scala> spark.sql("select * from test2").createOrReplaceTempView("tmp001")

We have disabled a test related to storage in the History server suite after SPARK-13845. But, after SPARK-22050, we can store the information about block updated events to eventLog, if we enable "spark.eventLog.logBlockUpdates.enabled=true".

In file source V1, if some file is deleted manually, reading the DataFrame/Table will throws an exception with suggestion message
```
It is possible the underlying files have been updated. You can explicitly invalidate the cache in Spark by running 'REFRESH TABLE tableName' command in SQL or by recreating the Dataset/DataFrame involved.

After refreshing the table/DataFrame, the reads should return correct results.

A previous change moved the removal of empty window expressions to the RemoveNoopOperations rule, which comes after the CollapseWindow rule. Therefore, by the time we get to CollapseWindow, we aren't guaranteed that empty windows have been removed. This change checks that the window expressions are not empty, and only collapses the windows if both windows are non-empty.

This patch modifies SparkBuild so that the largest / slowest test suites (or collections of suites) can run in their own forked JVMs, allowing them to be run in parallel with each other. This opt-in / whitelisting approach allows us to increase parallelism without having to fix a long-tail of flakiness / brittleness issues in tests which aren't performance bottlenecks.
See comments in SparkBuild.scala for information on the details, including a summary of why we sometimes opt to run entire groups of tests in a single forked JVM .

## What changes were proposed in this pull request?
https://github.com/apache/spark/pull/24332 introduced an unnecessary `import` statement and two slight issues in the codegen templates in `Cast` for `Date` <-> `Timestamp`.
This PR removes the unused import statement and fixes the slight codegen issue.
The issue in those two codegen templates is this pattern:
```scala
val zid = JavaCode.global(
ctx.addReferenceObj("zoneId", zoneId, "java.time.ZoneId"),
zoneId.getClass)
```
`zoneId` can refer to an instance of a non-public class, e.g. `java.time.ZoneRegion`, and while this code correctly puts in the 3rd argument to `ctx.addReferenceObj()`, it's still passing `zoneId.getClass` to `JavaCode.global()` which is not desirable, but doesn't cause any immediate bugs in this particular case, because `zid` is used in an expression immediately afterwards.
If this `zid` ever needs to spill to any explicitly typed variables, e.g. a local variable, and if the spill handling uses the `javaType` on this `GlobalVariable`, it'd generate code that looks like:
```java
java.time.ZoneRegion value1 = ((java.time.ZoneId) references[2] /* literal */);
```
which would then be a real bug:
- a non-accessible type `java.time.ZoneRegion` is referenced in the generated code, and
- `ZoneId` -> `ZoneRegion` requires an explicit downcast.
## How was this patch tested?
Existing tests. This PR does not change behavior, and the original PR won't cause any real behavior bug to begin with.

Our customer has a very complicated job. Sometimes it successes and sometimes it fails with
```
Caused by: org.apache.spark.SparkException: Job aborted due to stage failure: ShuffleMapStage 4 has failed the maximum allowable number of times: 4.
Most recent failure reason: org.apache.spark.shuffle.FetchFailedException
```
However, with the patch https://github.com/apache/spark/pull/23871 , the job hangs forever.
When I investigated it, I found that `DAGScheduler` and `TaskSchedulerImpl` define stage completion differently. `DAGScheduler` thinks a stage is completed if all its partitions are marked as completed ([result stage](https://github.com/apache/spark/blob/v2.4.1/core/src/main/scala/org/apache/spark/scheduler/DAGScheduler.scala#L1362-L1368) and [shuffle stage](https://github.com/apache/spark/blob/v2.4.1/core/src/main/scala/org/apache/spark/scheduler/DAGScheduler.scala#L1400)). `TaskSchedulerImpl` thinks a stage's task set is completed when all tasks finish (see the [code](https://github.com/apache/spark/blob/v2.4.1/core/src/main/scala/org/apache/spark/scheduler/TaskSetManager.scala#L779-L784)).
Ideally this two definition should be consistent, but #23871 breaks it. In our customer's Spark log, I found that, a stage's task set completes, but the stage never completes. More specifically, `DAGScheduler` submits a task set for stage 4.1 with 1000 tasks, but the `TaskSetManager` skips to run the first 100 tasks. Later on, `TaskSetManager` finishes 900 tasks and marks the task set as completed. However, `DAGScheduler` doesn't agree with it and hangs forever, waiting for more task completion events of stage 4.1.
With hindsight, I think `TaskSchedulerIImpl.stageIdToFinishedPartitions` is fragile. We need to pay more effort to make sure this is consistent with `DAGScheduler`'s knowledge. When `DAGScheduler` marks some partitions from finished to unfinished, `TaskSchedulerIImpl.stageIdToFinishedPartitions` should be updated as well.
This PR reverts #23871, let's think of a more robust idea later.

The RBackend and RBackendHandler create new conf objects that don't pick up conf values from the existing SparkSession and therefore always use the default conf values instead of values specified by the user.
In this fix we check to see if the spark env already exists, and get the conf from there. We fall back to creating a new conf. This follows the pattern used in other places including this: 3725b1324f/core/src/main/scala/org/apache/spark/api/r/BaseRRunner.scala (L261)

## What changes were proposed in this pull request?
SPARK-27199 introduced the use of `ZoneId` instead of `TimeZone` in a few date/time expressions.
There were 3 occurrences of `ctx.addReferenceObj("zoneId", zoneId)` in that PR, which had a bug because while the `java.time.ZoneId` base type is public, the actual concrete implementation classes are not public, so using the 2-arg version of `CodegenContext.addReferenceObj` would incorrectly generate code that reference non-public types (`java.time.ZoneRegion`, to be specific). The 3-arg version should be used, with the class name of the referenced object explicitly specified to the public base type.
One of such occurrences was caught in testing in the main PR of SPARK-27199 (https://github.com/apache/spark/pull/24141), for `DateFormatClass`. But the other 2 occurrences slipped through because there were no test cases that covered them.
Example of this bug in the current Apache Spark master, in a Spark Shell:
```

java.lang.IllegalAccessError: tried to access class java.time.ZoneRegion from class org.apache.spark.sql.catalyst.expressions.GeneratedClass$GeneratedIteratorForCodegenStage1
```
This PR fixes the codegen issues and adds the corresponding unit tests.
## How was this patch tested?
Enhanced tests in `DateExpressionsSuite` for `to_unix_timestamp` and `from_unixtime`.

## What changes were proposed in this pull request?
`Krb5LoginModule` supports debug parameter which is not yet supported from Spark side. This configuration makes it easier to debug authentication issues against Kafka.
In this PR `Krb5LoginModule` debug flag controlled by either `sun.security.krb5.debug` or `com.ibm.security.krb5.Krb5Debug`.
Additionally found some hardcoded values like `ssl.truststore.location`, etc... which could be error prone if Kafka changes it so in such cases Kafka define used.
## How was this patch tested?
Existing + additional unit tests + on cluster.

While using vi or vim to edit the test files the .swp or .swo files are created and attempt to run the test suite in the presence of these files causes errors like below :
```

~~This minor pr adds these temp files in the ignore list.~~
While computing the list of test files to process, only consider files with `.sql` extension. This makes sure the unwanted temp files created from various editors are ignored from processing.

## What changes were proposed in this pull request?
Fix build warnings -- see some details below.
But mostly, remove use of postfix syntax where it causes warnings without the `scala.language.postfixOps` import. This is mostly in expressions like "120000 milliseconds". Which, I'd like to simplify to things like "2.minutes" anyway.

## What changes were proposed in this pull request?
This PR extends the existing BROADCAST join hint (for both broadcast-hash join and broadcast-nested-loop join) by implementing other join strategy hints corresponding to the rest of Spark's existing join strategies: shuffle-hash, sort-merge, cartesian-product. The hint names: SHUFFLE_MERGE, SHUFFLE_HASH, SHUFFLE_REPLICATE_NL are partly different from the code names in order to make them clearer to users and reflect the actual algorithms better.
The hinted strategy will be used for the join with which it is associated if it is applicable/doable.
Conflict resolving rules in case of multiple hints:
1. Conflicts within either side of the join: take the first strategy hint specified in the query, or the top hint node in Dataset. For example, in "select /*+ merge(t1) */ /*+ broadcast(t1) */ k1, v2 from t1 join t2 on t1.k1 = t2.k2", take "merge(t1)"; in ```df1.hint("merge").hint("shuffle_hash").join(df2)```, take "shuffle_hash". This is a general hint conflict resolving strategy, not specific to join strategy hint.
2. Conflicts between two sides of the join:
a) In case of different strategy hints, hints are prioritized as ```BROADCAST``` over ```SHUFFLE_MERGE``` over ```SHUFFLE_HASH``` over ```SHUFFLE_REPLICATE_NL```.
b) In case of same strategy hints but conflicts in build side, choose the build side based on join type and size.
## How was this patch tested?
Added new UTs.

## What changes were proposed in this pull request?
System shall update the table stats automatically if user set spark.sql.statistics.size.autoUpdate.enabled as true, currently this property is not having any significance even if it is enabled or disabled. This feature is similar to Hives auto-gather feature where statistics are automatically computed by default if this feature is enabled.
Reference:
https://cwiki.apache.org/confluence/display/Hive/StatsDev
As part of fix , autoSizeUpdateEnabled validation is been done initially so that system will calculate the table size for the user automatically and record it in metastore as per user expectation.
## How was this patch tested?
UT is written and manually verified in cluster.
Tested with unit tests + some internal tests on real cluster.

I propose to disable (comment) result checking in `SorterSuite`.`java.lang.ArrayIndexOutOfBoundsException in TimSort` because:
1. The check is optional, and correctness of TimSort is checked by another tests. Purpose of the test is to check that TimSort doesn't fail with `ArrayIndexOutOfBoundsException`.
2. Significantly drops execution time of the test.
Here are timing of running the test locally:
```
Sort: 1.4 seconds
Result checking: 15.6 seconds
```
