I happened to meet this case few times before:
```

```
I typed the fix version wrongly (there's comma in `3.0,0`) and it ended the loop in the merge script. Not a big deal but it bugged me few times. Finally I met this today again, and decided to fix.
This PR proposes to recover from wrongly set fix versions.
## How was this patch tested?
I manually copied and pasted the specific codes and tested separately in both Python 2 and Python 3.
**Positive cases:**
```

['3.0.0']
```
```
Enter comma-separated fix version(s) [3.0.0,2.4.2]: # multiple default versions
['3.0.0', '2.4.2']
```
```
Enter comma-separated fix version(s) [3.0.0]: 2.4.1 # valid version
['2.4.1']
```
```
Enter comma-separated fix version(s) [3.0.0]: 3.0.0,2.4.2 # multiple valid versions
['3.0.0', '2.4.2']
```

## What changes were proposed in this pull request?
Currently in the grammar file the rule `query` is responsible to parse both select and insert statements. As a result, we need to have more semantic checks in the code to guard against in-valid insert constructs in a query. Couple of examples are in the `visitCreateView` and `visitAlterView` functions. One other issue is that, we don't catch the `invalid insert constructs` in all the places until checkAnalysis (the errors we raise can be confusing as well). Here are couple of examples :
```SQL
select * from (insert into bar values (2));
```
```
Error in query: unresolved operator 'Project [*];
'Project [*]
+- SubqueryAlias `__auto_generated_subquery_name`
+- InsertIntoHiveTable `default`.`bar`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, false, false, [c1]
+- Project [cast(col1#18 as int) AS c1#20]
+- LocalRelation [col1#18]
```
```SQL
select * from foo where c1 in (insert into bar values (2))
```
```
Error in query: cannot resolve '(default.foo.`c1` IN (listquery()))' due to data type mismatch:
The number of columns in the left hand side of an IN subquery does not match the
number of columns in the output of subquery.
#columns in left hand side: 1.
#columns in right hand side: 0.
Left side columns:
[default.foo.`c1`].
Right side columns:
[].;;
'Project [*]
+- 'Filter c1#6 IN (list#5 [])
: +- InsertIntoHiveTable `default`.`bar`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, false, false, [c1]
: +- Project [cast(col1#7 as int) AS c1#9]
: +- LocalRelation [col1#7]
+- SubqueryAlias `default`.`foo`
+- HiveTableRelation `default`.`foo`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [c1#6]
```
For both the cases above, we should reject the syntax at parser level.
In this PR, we create two top-level parser rules to parse `SELECT` and `INSERT` respectively.
I will create a small PR to allow CTEs in DESCRIBE QUERY after this PR is in.

This PR proposes to add an assert on `ScalarSubquery`'s `dataType` because there's a possibility that `dataType` can be called alone before throwing analysis exception.
This was found while working on [SPARK-27088](https://issues.apache.org/jira/browse/SPARK-27088). This change calls `treeString` for logging purpose, and the specific test "scalar subquery with no column" under `AnalysisErrorSuite` was being failed with:
```
Caused by: sbt.ForkMain$ForkError: java.util.NoSuchElementException: next on empty iterator
...
at scala.collection.mutable.ArrayOps$ofRef.head(ArrayOps.scala:198)

...
```
The reason is that `treeString` for logging happened to call `dataType` on `ScalarSubquery` but one test has empty column plan. So, it happened to throw `NoSuchElementException` before checking analysis.
## How was this patch tested?
Manually tested.

As per https://docs.oracle.com/javase/8/docs/api/java/lang/ClassLoader.html
``Class loaders that support concurrent loading of classes are known as parallel capable class loaders and are required to register themselves at their class initialization time by invoking the ClassLoader.registerAsParallelCapable method. Note that the ClassLoader class is registered as parallel capable by default. However, its subclasses still need to register themselves if they are parallel capable. ``
i.e we can have finer class loading locks by registering classloaders as parallel capable. (Refer to deadlock due to macro lock https://issues.apache.org/jira/browse/SPARK-26961).
All the classloaders we have are wrapper of URLClassLoader which by itself is parallel capable.
But this cannot be achieved by scala code due to static registration Refer https://github.com/scala/bug/issues/11429

Currently, if we want to configure `spark.sql.files.maxPartitionBytes` to 256 megabytes, we must set `spark.sql.files.maxPartitionBytes=268435456`, which is very unfriendly to users.
And if we set it like this:`spark.sql.files.maxPartitionBytes=256M`, we will encounter this exception:
```

Now that we support returning pandas DataFrame for struct type in Scalar Pandas UDF.
If we chain another Pandas UDF after the Scalar Pandas UDF returning pandas DataFrame, the argument of the chained UDF will be pandas DataFrame, but currently we don't support pandas DataFrame as an argument of Scalar Pandas UDF. That means there is an inconsistency between the chained UDF and the single UDF.
We should support taking pandas DataFrame for struct type argument in Scalar Pandas UDF to be consistent.
Currently pyarrow >=0.11 is supported.

When a timeout happens we don't know what's the state of the remote end,
so there is no point in doing anything else since it will most probably
fail anyway.
The change also demotes the log message printed when falling back to
SASL, since a warning is too noisy for when the fallback is really
needed (e.g. old shuffle service, or shuffle service with new auth
disabled).

Hive UDAF knows the aggregation mode when creating the aggregation buffer, so that it can create different buffers for different inputs: the original data or the aggregation buffer. Please see an example in the [sketches library](7f9e76e9e0/src/main/java/com/yahoo/sketches/hive/cpc/DataToSketchUDAF.java (L107)).
However, the Hive UDAF adapter in Spark always creates the buffer with partial1 mode, which can only deal with one input: the original data. This PR fixes it.
All credits go to pgandhi999 , who investigate the problem and study the Hive UDAF behaviors, and write the tests.

## What changes were proposed in this pull request?
This patch fixes the issue that ClientEndpoint in standalone cluster doesn't recognize about driver options which are passed to SparkConf instead of system properties. When `Client` is executed via cli they should be provided as system properties, but with `spark-submit` they can be provided as SparkConf. (SpartSubmit will call `ClientApp.start` with SparkConf which would contain these options.)
## How was this patch tested?

1) setup standalone cluster (launch master and worker via `./sbin/start-all.sh`)
2) submit one of example app with standalone cluster mode

This moves parsing `CREATE TABLE ... USING` statements into catalyst. Catalyst produces logical plans with the parsed information and those plans are converted to v1 `DataSource` plans in `DataSourceAnalysis`.
This prepares for adding v2 create plans that should receive the information parsed from SQL without being translated to v1 plans first.
This also makes it possible to parse in catalyst instead of breaking the parser across the abstract `AstBuilder` in catalyst and `SparkSqlParser` in core.

## How was this patch tested?
Added UT.
Closes#24154 from HeartSaVioR/SPARK-27210.

## What changes were proposed in this pull request?
This PR adds support for casting
* `ByteType`
* `ShortType`
* `IntegerType`
* `LongType`
to `BinaryType`.
## How was this patch tested?
We added unit tests for casting instances of the above types. For validation, we used Javas `DataOutputStream` to compare the resulting byte array with the result of `Cast`.
We state that the contribution is our original work and that we license the work to the project under the project’s open source license.
cloud-fan we'd appreciate a review if you find the time, thx

## What changes were proposed in this pull request?
In the PR, I propose to avoid the `TimeZone` to `ZoneId` conversion in `DateTimeUtils.stringToTimestamp` by changing signature of the method, and require a parameter of `ZoneId` type. This will allow to avoid unnecessary conversion (`TimeZone` -> `String` -> `ZoneId`) per each row.
Also the PR avoids creation of `ZoneId` instances from `ZoneOffset` because `ZoneOffset` is a sub-class, and the conversion is unnecessary too.

This pr extended `ANALYZE` commands to analyze column stats for cached table.
In common use cases, users read catalog table data, join/aggregate them, and then cache the result for following reuse. Since we are only allowed to analyze column statistics in catalog tables via ANALYZE commands, the current optimization depends on non-existing or inaccurate column statistics of cached data. So, it would be great if we could analyze cached data as follows;
```scala
scala> def printColumnStats(tableName: String) = {
| spark.table(tableName).queryExecution.optimizedPlan.stats.attributeStats.foreach {
| case (k, v) => println(s"[$k]: $v")
| }
| }
scala> sql("SET spark.sql.cbo.enabled=true")
scala> sql("SET spark.sql.statistics.histogram.enabled=true")
scala> spark.range(1000).selectExpr("id % 33 AS c0", "rand() AS c1", "0 AS c2").write.saveAsTable("t")
scala> sql("ANALYZE TABLE t COMPUTE STATISTICS FOR COLUMNS c0, c1, c2")
scala> spark.table("t").groupBy("c0").agg(count("c1").as("v1"), sum("c2").as("v2")).createTempView("temp")
// Prints column statistics in catalog table `t`
scala> printColumnStats("t")
[c0#7073L]: ColumnStat(Some(33),Some(0),Some(32),Some(0),Some(8),Some(8),Some(Histogram(3.937007874015748,[Lorg.apache.spark.sql.catalyst.plans.logical.HistogramBin;9f7c1c)),2)

## What changes were proposed in this pull request?
This change is a cleanup and consolidation of 3 areas related to Pandas UDFs:
1) `ArrowStreamPandasSerializer` now inherits from `ArrowStreamSerializer` and uses the base class `dump_stream`, `load_stream` to create Arrow reader/writer and send Arrow record batches. `ArrowStreamPandasSerializer` makes the conversions to/from Pandas and converts to Arrow record batch iterators. This change removed duplicated creation of Arrow readers/writers.
2) `createDataFrame` with Arrow now uses `ArrowStreamPandasSerializer` instead of doing its own conversions from Pandas to Arrow and sending record batches through `ArrowStreamSerializer`.
3) Grouped Map UDFs now reuse existing logic in `ArrowStreamPandasSerializer` to send Pandas DataFrame results as a `StructType` instead of separating each column from the DataFrame. This makes the code a little more consistent with the Python worker, but does require that the returned StructType column is flattened out in `FlatMapGroupsInPandasExec` in Scala.

Currently aliases are not handled in the Aggregate Estimation due to which stats are not getting propagated. This causes CBO join-reordering to not give optimal join plans. ProjectEstimation is already taking care of aliases, we need same logic for AggregateEstimation as well to properly propagate stats when CBO is enabled.

## What changes were proposed in this pull request?
When passing in a user schema to create a DataFrame, there might be mismatched nullability between the user schema and the the actual data. All related public interfaces now perform catalyst conversion using the user provided schema, which catches such mismatches to avoid runtime errors later on. However, there're private methods which allow this conversion to be skipped, so we need to remove these private methods which may lead to confusion and potential issues.
## How was this patch tested?
Passed existing tests. No new tests were added since this PR removed the private interfaces that would potentially cause null problems and other interfaces are covered already by existing tests.

[SPARK-26977](https://issues.apache.org/jira/browse/SPARK-26977) introduced very strange bug which spark-shell is no longer able to load classes which are provided via `--packages`. TBH I don't know about the details why it is broken, but looks like initializing `object class` brings the weirdness (maybe due to static initialization done twice?).
This patch removes the logic to leave warning log when main class is scala.App, to not deal with such complexity for just leaving warning message.
## How was this patch tested?
Manual test: suppose we run spark-shell with `--packages` option like below:
```
./bin/spark-shell --verbose --master "local[*]" --packages org.apache.spark:spark-sql-kafka-0-10_2.11:2.4.0
```
Before this patch, importing class in transitive dependency fails:
```
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
