Kousuke Saruta c3ce9701b4 [SPARK-33533][SQL] Fix the regression bug that ConnectionProviders don't consider case-sensitivity for properties
### What changes were proposed in this pull request?

This PR fixes an issue that `BasicConnectionProvider` doesn't consider case-sensitivity for properties.
For example, the property `oracle.jdbc.mapDateToTimestamp` should be considered case-sensitivity but it is not considered.

### Why are the changes needed?

This is a bug introduced by #29024 .
Caused by this issue, `OracleIntegrationSuite` doesn't pass.

Jungtaek Lim (HeartSaVioR) edab094dda [SPARK-33224][SS][WEBUI] Add watermark gap information into SS UI page
### What changes were proposed in this pull request?

This PR proposes to add the watermark gap information in SS UI page. Please refer below screenshots to see what we'd like to show in UI.

![Screen Shot 2020-11-19 at 6 56 38 PM](https://user-images.githubusercontent.com/1317309/99669306-3532d080-2ab2-11eb-9a93-03d2c6a54948.png)

Please note that this PR doesn't plot the watermark value - knowing the gap between actual wall clock and watermark looks more useful than the absolute value.

### Why are the changes needed?

Watermark is the one of major metrics the end users need to track for stateful queries. Watermark defines "when" the output will be emitted for append mode, hence knowing how much gap between wall clock and watermark (input data) is very helpful to make expectation of the output.

### Does this PR introduce _any_ user-facing change?

Yes, SS UI query page will contain the watermark gap information.

### How was this patch tested?

Basic UT added. Manually tested with two queries:

> simple case

You'll see consistent watermark gap with (15 seconds + a) = 10 seconds are from delay in watermark definition, 5 seconds are trigger interval.

```
import org.apache.spark.sql.streaming.Trigger

spark.conf.set("spark.sql.shuffle.partitions", "10")

val query = spark
  .readStream
  .format("rate")
  .option("rowsPerSecond", 1000)
  .option("rampUpTime", "10s")
  .load()
  .selectExpr("timestamp", "mod(value, 100) as mod", "value")
  .withWatermark("timestamp", "10 seconds")
  .groupBy(window($"timestamp", "1 minute", "10 seconds"), $"mod")
  .agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value"))
  .writeStream
  .format("console")
  .trigger(Trigger.ProcessingTime("5 seconds"))
  .outputMode("append")
  .start()

query.awaitTermination()
```

![Screen Shot 2020-11-19 at 7 00 21 PM](https://user-images.githubusercontent.com/1317309/99669049-dbcaa180-2ab1-11eb-8789-10b35857dda0.png)

> complicated case

This randomizes the timestamp, hence producing random watermark gap. This won't be smaller than 15 seconds as I described earlier.

```
import org.apache.spark.sql.streaming.Trigger

spark.conf.set("spark.sql.shuffle.partitions", "10")

val query = spark
  .readStream
  .format("rate")
  .option("rowsPerSecond", 1000)
  .option("rampUpTime", "10s")
  .load()
  .selectExpr("*", "CAST(CAST(timestamp AS BIGINT) - CAST((RAND() * 100000) AS BIGINT) AS TIMESTAMP) AS tsMod")
  .selectExpr("tsMod", "mod(value, 100) as mod", "value")
  .withWatermark("tsMod", "10 seconds")
  .groupBy(window($"tsMod", "1 minute", "10 seconds"), $"mod")
  .agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value"))
  .writeStream
  .format("console")
  .trigger(Trigger.ProcessingTime("5 seconds"))
  .outputMode("append")
  .start()

query.awaitTermination()
```

Terry Kim b7f034d8dc [SPARK-33543][SQL] Migrate SHOW COLUMNS command to use UnresolvedTableOrView to resolve the identifier
### What changes were proposed in this pull request?

This PR proposes to migrate `SHOW COLUMNS` to use `UnresolvedTableOrView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

Note that `SHOW COLUMNS` is not yet supported for v2 tables.

### Why are the changes needed?

To use `UnresolvedTableOrView` for table/view resolution. Note that `ShowColumnsCommand` internally resolves to a temp view first, so there is no resolution behavior change with this PR.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Updated existing tests.

Wenchen Fan d1b4f06179 [SPARK-33494][SQL][AQE] Do not use local shuffle reader for repartition
### What changes were proposed in this pull request?

This PR updates `ShuffleExchangeExec` to carry more information about how much we can change the partitioning. For `repartition(col)`, we should preserve the user-specified partitioning and don't apply the AQE local shuffle reader.

### Why are the changes needed?

Similar to `repartition(number, col)`, we should respect the user-specified partitioning.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

Terry Kim fdd6c73b3c [SPARK-33514][SQL] Migrate TRUNCATE TABLE command to use UnresolvedTable to resolve the identifier
### What changes were proposed in this pull request?

This PR proposes to migrate `TRUNCATE TABLE` to use `UnresolvedTable` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

Note that `TRUNCATE TABLE` works only with v1 tables, and not supported for v2 tables.

### Why are the changes needed?

The changes allow consistent resolution behavior when resolving the table identifier. For example, the following is the current behavior:
```scala
sql("CREATE TEMPORARY VIEW t AS SELECT 1")
sql("CREATE DATABASE db")
sql("CREATE TABLE t using csv AS SELECT 1")
sql("USE db")
sql("TRUNCATE TABLE t") // Succeeds
```
With this PR, `TRUNCATE TABLE` above fails with the following:
```
org.apache.spark.sql.AnalysisException: t is a temp view not table.; line 1 pos 0
    at org.apache.spark.sql.catalyst.analysis.package$AnalysisErrorAt.failAnalysis(package.scala:42)
    at org.apache.spark.sql.catalyst.analysis.Analyzer$ResolveTempViews$$anonfun$apply$7.$anonfun$applyOrElse$42(Analyzer.scala:866)

```
, which is expected since temporary view is resolved first and `TRUNCATE TABLE` doesn't support a temporary view.

### Does this PR introduce _any_ user-facing change?

After this PR, `TRUNCATE TABLE` is resolved to a temp view `t` instead of table `db.t` in the above scenario.

### How was this patch tested?

Updated existing tests.

Max Gekk a6555ee596 [SPARK-33521][SQL] Universal type conversion in resolving V2 partition specs
### What changes were proposed in this pull request?
In the PR, I propose to changes the resolver of partition specs used in V2 `ALTER TABLE .. ADD/DROP PARTITION` (at the moment), and re-use `CAST` in conversion partition values to desired types according to the partition schema.

### Why are the changes needed?
Currently, the resolver of V2 partition specs supports just a few types: 23e9920b39/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/ResolvePartitionSpec.scala (L72), and fails on other types like date/timestamp.

### Does this PR introduce _any_ user-facing change?

[SPARK-33513][BUILD] Upgrade to Scala 2.13.4 to improve exhaustivity
### What changes were proposed in this pull request?

This PR aims the followings.
1. Upgrade from Scala 2.13.3 to 2.13.4 for Apache Spark 3.1
2. Fix exhaustivity issues in both Scala 2.12/2.13 (Scala 2.13.4 requires this for compilation.)
3. Enforce the improved exhaustive check by using the existing Scala 2.13 GitHub Action compilation job.

### Why are the changes needed?

Scala 2.13.4 is a maintenance release for 2.13 line and improves JDK 15 support.
- https://github.com/scala/scala/releases/tag/v2.13.4

Also, it improves exhaustivity check.

- https://github.com/scala/scala/pull/9147 (Check all bindings exhaustively, e.g. tuples components)

### Does this PR introduce _any_ user-facing change?

Yep. Although it's a maintenance version change, it's a Scala version change.

### How was this patch tested?

Pass the CIs and do the manual testing.
- Scala 2.12 CI jobs(GitHub Action/Jenkins UT/Jenkins K8s IT) to check the validity of code change.
- Scala 2.13 Compilation job to check the compilation

### What changes were proposed in this pull request?
https://github.com/apache/spark/pull/30178 provided `OptimizeWindowFunctions` used to transfer `first` to `nth_value`.
If the window frame is `UNBOUNDED PRECEDING AND CURRENT ROW` or `UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING`, `nth_value` has better performance than `first`.
But the `OptimizeWindowFunctions` need to exclude other window frame.

### Why are the changes needed?
 Improve `OptimizeWindowFunctions` to avoid transfer `first` to `nth_value` if the specified window frame isn't `UNBOUNDED PRECEDING AND CURRENT ROW` or `UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING`.

### Does this PR introduce _any_ user-facing change?
'No'.

Max Gekk 23e9920b39 [SPARK-33511][SQL] Respect case sensitivity while resolving V2 partition specs
### What changes were proposed in this pull request?
1. Pre-process partition specs in `ResolvePartitionSpec`, and convert partition names according to the partition schema and the SQL config `spark.sql.caseSensitive`. In the PR, I propose to invoke `normalizePartitionSpec` for that. The function is used in DSv1 commands, so, the behavior will be similar to DSv1.
2. Move `normalizePartitionSpec()` from `sql/core/.../datasources/PartitioningUtils` to `sql/catalyst/.../util/PartitioningUtils` to use it in Catalyst's rule `ResolvePartitionSpec`

### Why are the changes needed?
DSv1 commands like `ALTER TABLE .. ADD PARTITION` and `ALTER TABLE .. DROP PARTITION` respect the SQL config `spark.sql.caseSensitive` while resolving partition specs. For example:
```sql
spark-sql> CREATE TABLE tbl1 (id bigint, data string) USING parquet PARTITIONED BY (id);
spark-sql> ALTER TABLE tbl1 ADD PARTITION (ID=1);
spark-sql> SHOW PARTITIONS tbl1;
id=1
```
The same command fails on V2 Table catalog with error:
```
AnalysisException: Partition key ID not exists
```

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, partition spec resolution works as for DSv1 (without the exception showed above).

### How was this patch tested?
By running `AlterTablePartitionV2SQLSuite`.

Terry Kim 60f3a730e4 [SPARK-33515][SQL] Improve exception messages while handling UnresolvedTable
### What changes were proposed in this pull request?

This PR proposes to improve the exception messages while `UnresolvedTable` is handled based on this suggestion: https://github.com/apache/spark/pull/30321#discussion_r521127001.

Currently, when an identifier is resolved to a view when a table is expected, the following exception message is displayed (e.g., for `COMMENT ON TABLE`):
```
v is a temp view not table.
```
After this PR, the message will be:
```
v is a temp view. 'COMMENT ON TABLE' expects a table.
```

Also, if an identifier is not resolved, the following exception message is currently used:
```
Table not found: t
```
After this PR, the message will be:
```
Table not found for 'COMMENT ON TABLE': t
```

### Why are the changes needed?

To improve the exception message.

### Does this PR introduce _any_ user-facing change?

Yes, the exception message will be changed as described above.

### How was this patch tested?

I think we need to consider the big picture. Trash directory is an important concept. If we decide to introduce it, we should consider all the code paths of Spark SQL that could delete the data, instead of Truncate only. We also need to consider what is the current behavior if the underlying file system does not provide the API `Trash.moveToAppropriateTrash`. Is the exception good? How about the performance when users are using the object store instead of HDFS? Will it impact the GDPR compliance?

In sum, I think we should not merge the PR https://github.com/apache/spark/pull/29552 without the design doc and implementation plan. That is why I reverted it before the code freeze of Spark 3.1

Liang-Chi Hsieh aa78c05edc [SPARK-33427][SQL][FOLLOWUP] Put key and value into IdentityHashMap sequantially
### What changes were proposed in this pull request?

This follow-up fixes an issue when inserting key/value pairs into `IdentityHashMap` in `SubExprEvaluationRuntime`.

### Why are the changes needed?

The last commits to #30341 follows review comment to use `IdentityHashMap`. Because we leverage `IdentityHashMap` to compare keys in reference, we should not convert expression pairs to Scala map before inserting. Scala map compares keys by equality so we will loss keys with different references.

CC Highman d338af3101 [SPARK-31962][SQL] Provide modifiedAfter and modifiedBefore options when filtering from a batch-based file data source
### What changes were proposed in this pull request?

Two new options, _modifiiedBefore_  and _modifiedAfter_, is provided expecting a value in 'YYYY-MM-DDTHH:mm:ss' format.  _PartioningAwareFileIndex_ considers these options during the process of checking for files, just before considering applied _PathFilters_ such as `pathGlobFilter.`  In order to filter file results, a new PathFilter class was derived for this purpose.  General house-keeping around classes extending PathFilter was performed for neatness.  It became apparent support was needed to handle multiple potential path filters.  Logic was introduced for this purpose and the associated tests written.

### Why are the changes needed?

When loading files from a data source, there can often times be thousands of file within a respective file path.  In many cases I've seen, we want to start loading from a folder path and ideally be able to begin loading files having modification dates past a certain point.  This would mean out of thousands of potential files, only the ones with modification dates greater than the specified timestamp would be considered.  This saves a ton of time automatically and reduces significant complexity managing this in code.

### Does this PR introduce _any_ user-facing change?

This PR introduces an option that can be used with batch-based Spark file data sources.  A documentation update was made to reflect an example and usage of the new data source option.

**Example Usages**
_Load all CSV files modified after date:_
`spark.read.format("csv").option("modifiedAfter","2020-06-15T05:00:00").load()`

_Load all CSV files modified before date:_
`spark.read.format("csv").option("modifiedBefore","2020-06-15T05:00:00").load()`

_Load all CSV files modified between two dates:_
`spark.read.format("csv").option("modifiedAfter","2019-01-15T05:00:00").option("modifiedBefore","2020-06-15T05:00:00").load()
`

### How was this patch tested?

### What changes were proposed in this pull request?
1. Add a hook method to `addPartitionKey()` of `InMemoryTable` which is called per every row.
2. Override `addPartitionKey()` in `InMemoryPartitionTable`, and add partition key every time when new row is inserted to the table.

### Why are the changes needed?
To be able to write unified tests for datasources V1 and V2. Currently, INSERT INTO a V1 table creates partitions but the same doesn't work for the custom catalog `InMemoryPartitionTableCatalog` used in DSv2 tests.

### Does this PR introduce _any_ user-facing change?

Jungtaek Lim (HeartSaVioR) 67c6ed9068 [SPARK-33223][SS][FOLLOWUP] Clarify the meaning of "number of rows dropped by watermark" in SS UI page
### What changes were proposed in this pull request?

This PR fixes the representation to clarify the meaning of "number of rows dropped by watermark" in SS UI page.

### Why are the changes needed?

`Aggregated Number Of State Rows Dropped By Watermark` says that the dropped rows are from the state, whereas they're not. We say "evicted from the state" for the case, which is "normal" to emit outputs and reduce memory usage of the state.

The metric actually represents the number of "input" rows dropped by watermark, and the meaning of "input" is relative to the "stateful operator". That's a bit confusing as we normally think "input" as "input from source" whereas it's not.

### Does this PR introduce _any_ user-facing change?

Yes, UI element & tooltip change.

### How was this patch tested?

Only text change in UI, so we know how thing will be changed intuitively.

anchovYu de0f50abf4 [SPARK-32670][SQL] Group exception messages in Catalyst Analyzer in one file
### What changes were proposed in this pull request?

Group all messages of `AnalysisExcpetions` created and thrown directly in org.apache.spark.sql.catalyst.analysis.Analyzer in one file.
* Create a new object: `org.apache.spark.sql.CatalystErrors` with many exception-creating functions.
* When the `Analyzer` wants to create and throw a new `AnalysisException`, call functions of `CatalystErrors`

### Why are the changes needed?

This is the sample PR that groups exception messages together in several files. It will largely help with standardization of error messages and its maintenance.

### Does this PR introduce _any_ user-facing change?

No. Error messages remain unchanged.

### How was this patch tested?

No new tests - pass all original tests to make sure it doesn't break any existing behavior.

### Naming of exception functions

All function names ended with `Error`.
* For specific errors like `groupingIDMismatch` and `groupingColInvalid`, directly use them as name, just like `groupingIDMismatchError` and `groupingColInvalidError`.
* For generic errors like `dataTypeMismatch`,
  * if confident with the context, prefix and condition can be added, like `pivotValDataTypeMismatchError`
  * if not sure about the context, add a `For` suffix of the specific component that this exception is related to, like `dataTypeMismatchForDeserializerError`

[SPARK-33492][SQL] DSv2: Append/Overwrite/ReplaceTable should invalidate cache
### What changes were proposed in this pull request?

This adds changes in the following places:
- logic to also refresh caches referencing the target table in v2 `AppendDataExec`, `OverwriteByExpressionExec`, `OverwritePartitionsDynamicExec`, as well as their v1 fallbacks `AppendDataExecV1` and `OverwriteByExpressionExecV1`.
- logic to invalidate caches referencing the target table in v2 `ReplaceTableAsSelectExec` and its atomic version `AtomicReplaceTableAsSelectExec`. These are only supported in v2 at the moment though.

In addition to the above, in order to test the v1 write fallback behavior, I extended `InMemoryTableWithV1Fallback` to also support batch reads.

### Why are the changes needed?

Currently in DataSource v2 we don't refresh or invalidate caches referencing the target table when the table content is changed by operations such as append, overwrite, or replace table. This is different from DataSource v1, and could potentially cause data correctness issue if the staled caches are queried later.

### Does this PR introduce _any_ user-facing change?

Yes. Now When a data source v2 is cached (either directly or indirectly), all the relevant caches will be refreshed or invalidated if the table is replaced.

### How was this patch tested?

Added unit tests for the new code path.

### What changes were proposed in this pull request?
Spark already support `LIKE ALL` syntax, but it will throw `StackOverflowError` if there are many elements(more than 14378 elements). We should implement built-in function for LIKE ALL to fix this issue.

Why the stack overflow can happen in the current approach ?
The current approach uses reduceLeft to connect each `Like(e, p)`, this will lead the the call depth of the thread is too large, causing `StackOverflowError` problems.

This PR support built-in function for `LIKE ALL` and avoid this issue.

### What changes were proposed in this pull request?

Change `CombineLimits` name to `EliminateLimits` and add check if `Limit` child max row <= limit.

### Why are the changes needed?

In Add-hoc scene, we always add limit for the query if user have no special limit value, but not all limit is nesessary.

A general negative example is
```
select count(*) from t limit 100000;
```

It will be great if we can eliminate limit at Spark side.

Also, we make a benchmark for this case
```
runBenchmark("Sort and Limit") {
  val N = 100000
  val benchmark = new Benchmark("benchmark sort and limit", N)

  benchmark.addCase("TakeOrderedAndProject", 3) { _ =>
    spark.range(N).toDF("c").repartition(200).sort("c").take(200000)
  }

  benchmark.addCase("Sort And Limit", 3) { _ =>
    withSQLConf("spark.sql.execution.topKSortFallbackThreshold" -> "-1") {
      spark.range(N).toDF("c").repartition(200).sort("c").take(200000)
    }
  }

  benchmark.addCase("Sort", 3) { _ =>
    spark.range(N).toDF("c").repartition(200).sort("c").collect()
  }
  benchmark.run()
}
```

and the result is
```

### What changes were proposed in this pull request?

This PR switched the order for the rule `RemoveRedundantSorts` and `EnsureRequirements` so that `EnsureRequirements` will be invoked before `RemoveRedundantSorts` to avoid IllegalArgumentException when instantiating PartitioningCollection.

### Why are the changes needed?
`RemoveRedundantSorts` rule uses SparkPlan's `outputPartitioning` to check whether a sort node is redundant. Currently, it is added before `EnsureRequirements`. Since `PartitioningCollection` requires left and right partitioning to have the same number of partitions, which is not necessarily true before applying `EnsureRequirements`, the rule can fail with the following exception:
```
IllegalArgumentException: requirement failed: PartitioningCollection requires all of its partitionings have the same numPartitions.

In this plan, the marked sort node could have been avoided as the data is already sorted on "t2.id" by the lower SortMergeJoin.

Gengliang Wang 9a4c79073b [SPARK-33354][SQL] New explicit cast syntax rules in ANSI mode
### What changes were proposed in this pull request?

In section 6.13 of the ANSI SQL standard, there are syntax rules for valid combinations of the source and target data types.
![image](https://user-images.githubusercontent.com/1097932/98212874-17356f80-1ef9-11eb-8f2b-385f32db404a.png)

Comparing the ANSI CAST syntax rules with the current default behavior of Spark:
![image](https://user-images.githubusercontent.com/1097932/98789831-b7870a80-23b7-11eb-9b5f-469a42e0ee4a.png)

To make Spark's ANSI mode more ANSI SQL Compatible,I propose to disallow the following casting in ANSI mode:
```
TimeStamp <=> Boolean
Date <=> Boolean
Numeric <=> Timestamp
Numeric <=> Date
Numeric <=> Binary
String <=> Array
String <=> Map
String <=> Struct
```
The following castings are considered invalid in ANSI SQL standard, but they are quite straight forward. Let's Allow them for now
```
Numeric <=> Boolean
String <=> Binary
```
### Why are the changes needed?

Better ANSI SQL compliance

### Does this PR introduce _any_ user-facing change?

Yes, the following castings will not be allowed in ANSI mode:
```
TimeStamp <=> Boolean
Date <=> Boolean
Numeric <=> Timestamp
Numeric <=> Date
Numeric <=> Binary
String <=> Array
String <=> Map
String <=> Struct
```

### How was this patch tested?

Ryan Blue 1df69f7e32 [SPARK-31255][SQL] Add SupportsMetadataColumns to DSv2
### What changes were proposed in this pull request?

This adds support for metadata columns to DataSourceV2. If a source implements `SupportsMetadataColumns` it must also implement `SupportsPushDownRequiredColumns` to support projecting those columns.

The analyzer is updated to resolve metadata columns from `LogicalPlan.metadataOutput`, and this adds a rule that will add metadata columns to the output of `DataSourceV2Relation` if one is used.

### Why are the changes needed?

This is the solution discussed for exposing additional data in the Kafka source. It is also needed for a generic `MERGE INTO` plan.

### Does this PR introduce any user-facing change?

Yes. Users can project additional columns from sources that implement the new API. This also updates `DescribeTableExec` to show metadata columns.

Liang-Chi Hsieh 928348408e [SPARK-33427][SQL] Add subexpression elimination for interpreted expression evaluation
### What changes were proposed in this pull request?

This patch proposes to add subexpression elimination for interpreted expression evaluation. Interpreted expression evaluation is used when codegen was not able to work, for example complex schema.

### Why are the changes needed?

Currently we only do subexpression elimination for codegen. For some reasons, we may need to run interpreted expression evaluation. For example, codegen fails to compile and fallbacks to interpreted mode, or complex input/output schema of expressions. It is commonly seen for complex schema from expressions that is possibly caused by the query optimizer too, e.g. SPARK-32945.

We should also support subexpression elimination for interpreted evaluation. That could reduce performance difference when Spark fallbacks from codegen to interpreted expression evaluation, and improve Spark usability.

Yuming Wang 09bb9bedcd [SPARK-33416][SQL] Avoid Hive metastore stack overflow when InSet predicate have many values
### What changes were proposed in this pull request?

We [rewrite](5197c5d2e7/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveShim.scala (L722-L724)) `In`/`InSet` predicate to `or` expressions when pruning Hive partitions. That will cause Hive metastore stack over flow if there are a lot of values.

This pr rewrite `InSet` predicate to `GreaterThanOrEqual` min value and `LessThanOrEqual ` max value when pruning Hive partitions to avoid Hive metastore stack overflow.

From our experience, `spark.sql.hive.metastorePartitionPruningInSetThreshold` should be less than 10000.

### Why are the changes needed?

Avoid Hive metastore stack overflow when `InSet` predicate have many values.
Especially DPP, it may generate many values.

### Does this PR introduce _any_ user-facing change?

No.

This PR proposes to simplify the exception messages from Python UDFS.

Currently, the exception message from Python UDFs is as below:

```python

```

```python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    print(self._jdf.showString(n, 20, vertical))

    return f(*args, **kwargs)

ZeroDivisionError: division by zero
```

Actually, almost all cases, users only care about `ZeroDivisionError: division by zero`. We don't really have to show the internal stuff in 99% cases.

This PR adds a configuration `spark.sql.execution.pyspark.udf.simplifiedException.enabled` (disabled by default) that hides the internal tracebacks related to Python worker, (de)serialization, etc.

```python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/.../python/pyspark/sql/dataframe.py", line 427, in show
    print(self._jdf.showString(n, 20, vertical))
  File "/.../python/lib/py4j-0.10.9-src.zip/py4j/java_gateway.py", line 1305, in __call__
  File "/.../python/pyspark/sql/utils.py", line 127, in deco
    raise_from(converted)
  File "<string>", line 3, in raise_from
pyspark.sql.utils.PythonException:
  An exception was thrown from Python worker in the executor:
Traceback (most recent call last):
  File "<stdin>", line 1, in <lambda>
ZeroDivisionError: division by zero
```

The trackback will be shown from the point when any non-PySpark file is seen in the traceback.

### Why are the changes needed?

Without this configuration. such internal tracebacks are exposed to users directly especially for shall or notebook users in PySpark. 99% cases people don't care about the internal Python worker, (de)serialization and related tracebacks. It just makes the exception more difficult to read. For example, one statement of `x/0` above shows a very long traceback and most of them are unnecessary.

This configuration enables the ability to show simplified tracebacks which users will likely be most interested in.

### Does this PR introduce _any_ user-facing change?

By default, no. It adds one configuration that simplifies the exception message. See the example above.

### How was this patch tested?

Manually tested:

```bash
$ pyspark --conf spark.sql.execution.pyspark.udf.simplifiedException.enabled=true
```
```python
from pyspark.sql.functions import udf; spark.sparkContext.setLogLevel("FATAL"); spark.range(10).select(udf(lambda x: x/0)("id")).collect()
```

and unittests were also added.
