### What changes were proposed in this pull request?
- Set `spark.sql.datetime.java8API.enabled` to `true` in `hiveResultString()`, and restore it back at the end of the call.
- Convert collected `java.time.Instant` & `java.time.LocalDate` to `java.sql.Timestamp` and `java.sql.Date` for correct formatting.
### Why are the changes needed?
Because of textual representation of timestamps/dates before 1582 year is incorrect:
```shell
$ export TZ="America/Los_Angeles"
$ ./bin/spark-sql -S
```
```sql
spark-sql> set spark.sql.session.timeZone=America/Los_Angeles;
spark.sql.session.timeZone America/Los_Angeles
spark-sql> SELECT DATE_TRUNC('MILLENNIUM', DATE '1970-03-20');
1001-01-01 00:07:02
```
It must be 1001-01-01 00:**00:00**.
### Does this PR introduce any user-facing change?
Yes. After the changes:
```shell
$ export TZ="America/Los_Angeles"
$ ./bin/spark-sql -S
```
```sql
spark-sql> set spark.sql.session.timeZone=America/Los_Angeles;
spark.sql.session.timeZone America/Los_Angeles
spark-sql> SELECT DATE_TRUNC('MILLENNIUM', DATE '1970-03-20');
1001-01-01 00:00:00
```
### How was this patch tested?
By running hive-thiftserver tests. In particular:
```

### What changes were proposed in this pull request?
No v2 command supports temp views and the `ResolveCatalogs`/`ResolveSessionCatalog` framework is designed with this assumption.
However, `ResolveSessionCatalog` needs to fallback to v1 commands, which do support temp views (e.g. CACHE TABLE). To work around it, we add a hack in `CatalogAndIdentifier`, which does not expand the given identifier with current namespace if the catalog is session catalog.
This works fine in most cases, as temp views should take precedence over tables during lookup. So if `CatalogAndIdentifier` returns a single name "t", the v1 commands can still resolve it to temp views correctly, or resolve it to table "default.t" if temp view doesn't exist.
However, if users write `spark_catalog.t`, it shouldn't be resolved to temp views as temp views don't belong to any catalog. `CatalogAndIdentifier` can't distinguish between `spark_catalog.t` and `t`, so the caller side may mistakenly resolve `spark_catalog.t` to a temp view.
This PR proposes to fix this issue by
1. remove the hack in `CatalogAndIdentifier`, and clearly document that this shouldn't be used to resolve temp views.
2. update `ResolveSessionCatalog` to explicitly look up temp views first before calling `CatalogAndIdentifier`, for v1 commands that support temp views.
### Why are the changes needed?
To avoid releasing a behavior that we should not support.
Removing the hack also fixes the problem we hit in https://github.com/apache/spark/pull/27532/files#diff-57b3d87be744b7d79a9beacf8e5e5eb2R937

### What changes were proposed in this pull request?
This PR scopes `SparkSession.active` to prevent problems with processing queries with possibly different spark sessions (and different configs). A new method, `withActive` is introduced on `SparkSession` that restores the previous spark session after the block of code is executed.
### Why are the changes needed?
`SparkSession.active` is a thread local variable that points to the current thread's spark session. It is important to note that the `SQLConf.get` method depends on `SparkSession.active`. In the current implementation it is possible that `SparkSession.active` points to a different session which causes various problems. Most of these problems arise because part of the query processing is done using the configurations of a different session. For example, when creating a data frame using a new session, i.e., `session.sql("...")`, part of the data frame is constructed using the currently active spark session, which can be a different session from the one used later for processing the query.
### Does this PR introduce any user-facing change?

### What changes were proposed in this pull request?
HiveTableScanExec does not prune partitions again after SessionCatalog.listPartitionsByFilter called.
### Why are the changes needed?
In HiveTableScanExec, it will push down to hive metastore for partition pruning if spark.sql.hive.metastorePartitionPruning is true, and then it will prune the returned partitions again using partition filters, because some predicates, eg. "b like 'xyz'", are not supported in hive metastore. But now this problem is already fixed in HiveExternalCatalog.listPartitionsByFilter, the HiveExternalCatalog.listPartitionsByFilter can return exactly what we want now. So it is not necessary any more to double prune in HiveTableScanExec.

## What changes were proposed in this pull request?
This patch adds a DDL command `SHOW CREATE TABLE AS SERDE`. It is used to generate Hive DDL for a Hive table.
For original `SHOW CREATE TABLE`, it now shows Spark DDL always. If given a Hive table, it tries to generate Spark DDL.
For Hive serde to data source conversion, this uses the existing mapping inside `HiveSerDe`. If can't find a mapping there, throws an analysis exception on unsupported serde configuration.
It is arguably that some Hive fileformat + row serde might be mapped to Spark data source, e.g., CSV. It is not included in this PR. To be conservative, it may not be supported.
For Hive serde properties, for now this doesn't save it to Spark DDL because it may not useful to keep Hive serde properties in Spark table.

Added test.

### What changes were proposed in this pull request?
This reverts commit b5cb9abdd5.
### Why are the changes needed?
The merged commit (#27243) was too risky for several reasons:
1. It doesn't fix a bug
2. It makes the resolution of the table that's going to be altered a child. We had avoided this on purpose as having an arbitrary rule change the child of AlterTable seemed risky. This change alone is a big -1 for me for this change.
3. While the code may look cleaner, I think this approach makes certain things harder, e.g. differentiating between the Hive based Alter table CHANGE COLUMN and ALTER COLUMN syntax. Resolving and normalizing columns for ALTER COLUMN also becomes a bit harder, as we now have to check every single AlterTable command instead of just a single ALTER TABLE ALTER COLUMN statement

### What changes were proposed in this pull request?
Add optimizer rule PruneHiveTablePartitions pruning hive table partitions based on filters on partition columns.
Doing so, the total size of pruned partitions may be small enough for broadcast join in JoinSelection strategy.
### Why are the changes needed?
In JoinSelection strategy, spark use the "plan.stats.sizeInBytes" to decide whether the plan is suitable for broadcast join.
Currently, "plan.stats.sizeInBytes" does not take "pruned partitions" into account, so it may miss some broadcast join and take sort-merge join instead, which will definitely impact join performance.
This PR aim at taking "pruned partitions" into account for hive table in "plan.stats.sizeInBytes" and then improve performance by using broadcast join if possible.

1. https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-DescribeTable/View/MaterializedView/Column
2. https://prestodb.io/docs/current/sql/describe.html
We should make it clear that DESCRIBE support both table and view, by renaming the command to `DescribeRelation`.
This PR also tunes the framework a little bit to support the case that a command accepts both table and view.

### What changes were proposed in this pull request?
In the PR, I propose to replace `.collect()`, `.count()` and `.foreach(_ => ())` in SQL benchmarks and use the `NoOp` datasource. I added an implicit class to `SqlBasedBenchmark` with the `.noop()` method. It can be used in benchmark like: `ds.noop()`. The last one is unfolded to `ds.write.format("noop").mode(Overwrite).save()`.
### Why are the changes needed?
To avoid additional overhead that `collect()` (and other actions) has. For example, `.collect()` has to convert values according to external types and pull data to the driver. This can hide actual performance regressions or improvements of benchmarked operations.

## What changes were proposed in this pull request?
Defines a new subclass of UDF: `UserDefinedAggregator`. Also allows `Aggregator` to be registered as a udf. Under the hood, the implementation is based on the internal `TypedImperativeAggregate` class that spark's predefined aggregators make use of. The effect is that custom user defined aggregators are now serialized only on partition boundaries instead of being serialized and deserialized at each input row.
The two new modes of using `Aggregator` are as follows:
```scala
val agg: Aggregator[IN, BUF, OUT] = // typed aggregator
val udaf1 = UserDefinedAggregator(agg)
val udaf2 = spark.udf.register("agg", agg)
```
## How was this patch tested?
Unit testing has been added that corresponds to the testing suites for `UserDefinedAggregateFunction`. Additionally, unit tests explicitly count the number of aggregator ser/de cycles to ensure that it is governed only by the number of data partitions.
To evaluate the performance impact, I did two comparisons.
The code and REPL results are recorded on [this gist](https://gist.github.com/erikerlandson/b0e106a4dbaf7f80b4f4f3a21f05f892)
To characterize its behavior I benchmarked both a relatively simple aggregator and then an aggregator with a complex structure (a t-digest).
### performance
The following compares the new `Aggregator` based aggregation against UDAF. In this scenario, the new aggregation is about 100x faster. The difference in performance impact depends on the complexity of the aggregator. For very simple aggregators (e.g. implementing 'sum', etc), the performance impact is more like 25-30%.

### What changes were proposed in this pull request?
Currently data columns are displayed in one line for show create table command, when the table has many columns (to make things even worse, columns may have long names or comments), the displayed result is really hard to read.
To improve readability, we print each column in a separate line. Note that other systems like Hive/MySQL also display in this way.
Also, for data columns, table properties and options, we put the right parenthesis to the end of the last column/property/option, instead of occupying a separate line.
### Why are the changes needed?
for better readability
### Does this PR introduce any user-facing change?
before the change:
```
spark-sql> show create table test_table;
CREATE TABLE `test_table` (`col1` INT COMMENT 'This is comment for column 1', `col2` STRING COMMENT 'This is comment for column 2', `col3` DOUBLE COMMENT 'This is comment for column 3')
USING parquet
OPTIONS (
`bar` '2',
`foo` '1'
)
TBLPROPERTIES (
'a' = 'x',
'b' = 'y'
)
```
after the change:
```
spark-sql> show create table test_table;
CREATE TABLE `test_table` (
`col1` INT COMMENT 'This is comment for column 1',

### What changes were proposed in this pull request?
In this pull request, we are going to support `SET OWNER` syntax for databases and namespaces,
```sql
ALTER (DATABASE|SCHEME|NAMESPACE) database_name SET OWNER [USER|ROLE|GROUP] user_or_role_group;
```
Before this commit 332e252a14, we didn't care much about ownerships for the catalog objects. In 332e252a14, we determined to use properties to store ownership staff, and temporarily used `alter database ... set dbproperties ...` to support switch ownership of a database. This PR aims to use the formal syntax to replace it.
In hive, `ownerName/Type` are fields of the database objects, also they can be normal properties.
```
create schema test1 with dbproperties('ownerName'='yaooqinn')
```
The create/alter database syntax will not change the owner to `yaooqinn` but store it in parameters. e.g.
```
+----------+----------+---------------------------------------------------------------+-------------+-------------+-----------------------+--+
| db_name | comment | location | owner_name | owner_type | parameters |
+----------+----------+---------------------------------------------------------------+-------------+-------------+-----------------------+--+
| test1 | | hdfs://quickstart.cloudera:8020/user/hive/warehouse/test1.db | anonymous | USER | {ownerName=yaooqinn} |
+----------+----------+---------------------------------------------------------------+-------------+-------------+-----------------------+--+
```
In this pull request, because we let the `ownerName` become reversed, so it will neither change the owner nor store in dbproperties, just be omitted silently.
## Why are the changes needed?
Formal syntax support for changing database ownership
### Does this PR introduce any user-facing change?
yes, add a new syntax

### What changes were proposed in this pull request?
Update CREATE VIEW command to store the current catalog and namespace instead of current database in view metadata. Also update analyzer to leverage the catalog and namespace in view metastore to resolve relations inside views.
Note that, this PR still keeps the way we resolve views, by recursively calling Analyzer. This is necessary because view text may contain CTE, window spec, etc. which needs rules outside of the main resolution batch (e.g. `CTESubstitution`)
### Why are the changes needed?
To resolve relations inside view correctly.
### Does this PR introduce any user-facing change?
Yes, fix a bug. Now tables referred by a view can be resolved correctly even if the current catalog/namespace has been updated.

### What changes were proposed in this pull request?
This patch is based on #23921 but revised to be simpler, as well as adds UT to test the behavior.
(This patch contains the commit from #23921 to retain credit.)
Spark loads new JARs for `ADD JAR` and `CREATE FUNCTION ... USING JAR` into jar classloader in shared state, and changes current thread's context classloader to jar classloader as many parts of remaining codes rely on current thread's context classloader.
This would work if the further queries will run in same thread and there's no change on context classloader for the thread, but once the context classloader of current thread is switched back by various reason, Spark fails to create instance of class for the function.
This bug mostly affects spark-shell, as spark-shell will roll back current thread's context classloader at every prompt. But it may also affects the case of job-server, where the queries may be running in multiple threads.
This patch fixes the issue via switching the context classloader to the classloader which loads the class. Hopefully FunctionBuilder created by `makeFunctionBuilder` has the information of Class as a part of closure, hence the Class itself can be provided regardless of current thread's context classloader.
### Why are the changes needed?
Without this patch, end users cannot execute Hive UDF using JAR twice in spark-shell.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
Currently if function lookup fails, spark will give it a second change by casting decimal type to double type. But for cases where decimal type doesn't exist, it's meaningless to lookup again and causes extra cost like unnecessary metastore access. We should throw exceptions directly in these cases.

### What changes were proposed in this pull request?
When querying a partitioned table with format `org.apache.hive.hcatalog.data.JsonSerDe` and more than one task runs in each executor concurrently, the following exception is encountered:
`java.lang.ClassCastException: java.util.ArrayList cannot be cast to org.apache.hive.hcatalog.data.HCatRecord`
The exception occurs in `HadoopTableReader.fillObject`.
`org.apache.hive.hcatalog.data.JsonSerDe#initialize` populates a `cachedObjectInspector` field by calling `HCatRecordObjectInspectorFactory.getHCatRecordObjectInspector`, which is not thread-safe; this `cachedObjectInspector` is returned by `JsonSerDe#getObjectInspector`.
We protect against this Hive bug by synchronizing on an object when we need to call `initialize` on `org.apache.hadoop.hive.serde2.Deserializer` instances (which may be `JsonSerDe` instances). By doing so, the `ObjectInspector` for the `Deserializer` of the partitions of the JSON table and that of the table `SerDe` are the same cached `ObjectInspector` and `HadoopTableReader.fillObject` then works correctly. (If the `ObjectInspector`s are different, then a bug in `HCatRecordObjectInspector` causes an `ArrayList` to be created instead of an `HCatRecord`, resulting in the `ClassCastException` that is seen.)
### Why are the changes needed?
To avoid HIVE-15773 / HIVE-21752.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Tested manually on a cluster with a partitioned JSON table and running a query using more than one core per executor. Before this change, the ClassCastException happens consistently. With this change it does not happen.

### What changes were proposed in this pull request?
We could get the Partitions Statistics Info.But in some specail case, The Info like totalSize，rawDataSize，rowCount maybe empty. When we do some ddls like
`desc formatted partition` ,the NumberFormatException is showed as below:
```
spark-sql> desc formatted table1 partition(year='2019', month='10', day='17', hour='23');
19/10/19 00:02:40 ERROR SparkSQLDriver: Failed in [desc formatted table1 partition(year='2019', month='10', day='17', hour='23')]

at scala.math.BigInt$.apply(BigInt.scala:77)
at org.apache.spark.sql.hive.client.HiveClientImpl$$anonfun$31.apply(HiveClientImpl.scala:1056)
```
Although we can use 'Analyze table partition ' to update the totalSize,rawDataSize or rowCount, it's unresonable for normal SQL to throw NumberFormatException for Empty totalSize.We should fix the empty case when readHiveStats.
### Why are the changes needed?
This is a related to the robustness of the code and may lead to unexpected exception in some unpredictable situation.Here is the case:

### What changes were proposed in this pull request?
Before this PR, the method `checkAnswer` in Object `QueryTest` returns an optional string. It doesn't throw exceptions when errors happen.
The actual exceptions are thrown in the trait `QueryTest`.
However, there are some test suites(`StreamSuite`, `SessionStateSuite`, `BinaryFileFormatSuite`, etc.) that use the no-op method `QueryTest.checkAnswer` and expect it to fail test cases when the execution results don't match the expected answers.
After this PR:
1. the method `checkAnswer` in Object `QueryTest` will fail tests on errors or unexpected results.
2. add a new method `getErrorMessageInCheckAnswer`, which is exactly the same as the previous version of `checkAnswer`. There are some test suites use this one to customize the test failure message.
3. for the test suites that extend the trait `QueryTest`, we should use the method `checkAnswer` directly, instead of calling the method from Object `QueryTest`.
### Why are the changes needed?
We should fix these method calls to perform actual validations in test suites.

No.

### What changes were proposed in this pull request?
In this PR, we propose to use the value of `spark.sql.source.default` as the provider for `CREATE TABLE` syntax instead of `hive` in Spark 3.0.
And to help the migration, we introduce a legacy conf `spark.sql.legacy.respectHiveDefaultProvider.enabled` and set its default to `false`.
### Why are the changes needed?
1. Currently, `CREATE TABLE` syntax use hive provider to create table while `DataFrameWriter.saveAsTable` API using the value of `spark.sql.source.default` as a provider to create table. It would be better to make them consistent.
2. User may gets confused in some cases. For example:
```
CREATE TABLE t1 (c1 INT) USING PARQUET;
CREATE TABLE t2 (c1 INT);
```
In these two DDLs, use may think that `t2` should also use parquet as default provider since Spark always advertise parquet as the default format. However, it's hive in this case.
On the other hand, if we omit the USING clause in a CTAS statement, we do pick parquet by default if `spark.sql.hive.convertCATS=true`:
```
CREATE TABLE t3 USING PARQUET AS SELECT 1 AS VALUE;
CREATE TABLE t4 AS SELECT 1 AS VALUE;
```
And these two cases together can be really confusing.
3. Now, Spark SQL is very independent and popular. We do not need to be fully consistent with Hive's behavior.
### Does this PR introduce any user-facing change?
Yes, before this PR, using `CREATE TABLE` syntax will use hive provider. But now, it use the value of `spark.sql.source.default` as its provider.
### How was this patch tested?
Added tests in `DDLParserSuite` and `HiveDDlSuite`.

### What changes were proposed in this pull request?
Where it generates a deprecation warning in Scala 2.13, replace Symbol shorthand syntax `'foo` with an equivalent.
### Why are the changes needed?
Symbol syntax `'foo` is deprecated in Scala 2.13. The lines changed below otherwise generate about 440 warnings when building for 2.13.
The previous PR directly replaced many usages with `Symbol("foo")`. But it's also used to specify Columns via implicit conversion (`.select('foo)`) or even where simple Strings are used (`.as('foo)`), as it's kind of an abstraction for interned Strings.
While I find this syntax confusing and would like to deprecate it, here I just replaced it where it generates a build warning (not sure why all occurrences don't): `$"foo"` or just `"foo"`.

### What changes were proposed in this pull request?
In SPARK-29421 (#26097) , we can specify a different table provider for `CREATE TABLE LIKE` via `USING provider`.
Hive support `STORED AS` new file format syntax:

CREATE TABLE tbl(a int) STORED AS TEXTFILE;
CREATE TABLE tbl2 LIKE tbl STORED AS PARQUET;

For Hive compatibility, we should also support `STORED AS` in `CREATE TABLE LIKE`.

### What changes were proposed in this pull request?
This patch adds Hive provider into table metadata in `HiveExternalCatalog.alterTableStats`. When we call `HiveClient.alterTable`, `alterTable` will erase if it can not find hive provider in given table metadata.
Rename table also has this issue.
### Why are the changes needed?
Because running `ANALYZE TABLE` on a Hive table, if the table has bucketing info, will erase existing bucket info.
### Does this PR introduce any user-facing change?
Yes. After this PR, running `ANALYZE TABLE` on Hive table, won't erase existing bucketing info.

[HIVE-12063](https://issues.apache.org/jira/browse/HIVE-12063) improved pad decimal numbers with trailing zeros to the scale of the column. The following description is copied from the description of HIVE-12063.
> HIVE-7373 was to address the problems of trimming tailing zeros by Hive, which caused many problems including treating 0.0, 0.00 and so on as 0, which has different precision/scale. Please refer to HIVE-7373 description. However, HIVE-7373 was reverted by HIVE-8745 while the underlying problems remained. HIVE-11835 was resolved recently to address one of the problems, where 0.0, 0.00, and so on cannot be read into decimal(1,1).
However, HIVE-11835 didn't address the problem of showing as 0 in query result for any decimal values such as 0.0, 0.00, etc. This causes confusion as 0 and 0.0 have different precision/scale than 0.
The proposal here is to pad zeros for query result to the type's scale. This not only removes the confusion described above, but also aligns with many other DBs. Internal decimal number representation doesn't change, however.

### What changes were proposed in this pull request?
This PR aims to remove `hive-2.3` profile from `sql/hive` module.
### Why are the changes needed?
Currently, we need `-Phive-1.2` or `-Phive-2.3` additionally to build `hive` or `hive-thriftserver` module. Without specifying it, the build fails like the following. This PR will recover it.
```

```
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR aims the followings.
- Add two profiles, `hive-1.2` and `hive-2.3` (default)
- Validate if we keep the existing combination at least. (Hadoop-2.7 + Hive 1.2 / Hadoop-3.2 + Hive 2.3).
For now, we assumes that `hive-1.2` is explicitly used with `hadoop-2.7` and `hive-2.3` with `hadoop-3.2`. The followings are beyond the scope of this PR.
- SPARK-29988 Adjust Jenkins jobs for `hive-1.2/2.3` combination
- SPARK-29989 Update release-script for `hive-1.2/2.3` combination
- SPARK-29991 Support `hive-1.2/2.3` in PR Builder
### Why are the changes needed?
This will help to switch our dependencies to update the exposed dependencies.
### Does this PR introduce any user-facing change?
This is a dev-only change that the build profile combinations are changed.
- `-Phadoop-2.7` => `-Phadoop-2.7 -Phive-1.2`
- `-Phadoop-3.2` => `-Phadoop-3.2 -Phive-2.3`
### How was this patch tested?
Pass the Jenkins with the dependency check and tests to make it sure we don't change anything for now.
- [Jenkins (-Phadoop-2.7 -Phive-1.2)](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/114192/consoleFull)
- [Jenkins (-Phadoop-3.2 -Phive-2.3)](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/114192/consoleFull)
Also, from now, GitHub Action validates the following combinations.

This is to refactor Predicate code; it mainly removed `newPredicate` from `SparkPlan`.
Modifications are listed below;
- Move `Predicate` from `o.a.s.sqlcatalyst.expressions.codegen.GeneratePredicate.scala` to `o.a.s.sqlcatalyst.expressions.predicates.scala`
- To resolve the name conflict, rename `o.a.s.sqlcatalyst.expressions.codegen.Predicate` to `o.a.s.sqlcatalyst.expressions.BasePredicate`
- Extend `CodeGeneratorWithInterpretedFallback ` for `BasePredicate`

````
Most of cases occurred in reading a table which created by an old Spark version.
After recreated the table, the issue will be gone.
After deep dive, the root cause is this external table is a non-partitioned table but the `LOCATION` set to a partitioned path {{/tablename/dt=yyyymmdd}}. The partitionSpec is inferred.
### Why are the changes needed?
Above error message is very confused. We need more details about assert failure information.
This issue caused by `PartitioningAwareFileIndex#inferPartitioning()`. For non-HiveMetastore Spark, it's useful. But for Hive table, it shouldn't infer partition if Hive tell us it's a non partitioned table. (new added)

### What changes were proposed in this pull request?
This PR aims to add `io.netty.tryReflectionSetAccessible=true` to the testing configuration for JDK11 because this is an officially documented requirement of Apache Arrow.
Apache Arrow community documented this requirement at `0.15.0` ([ARROW-6206](https://github.com/apache/arrow/pull/5078)).
> #### For java 9 or later, should set "-Dio.netty.tryReflectionSetAccessible=true".
> This fixes `java.lang.UnsupportedOperationException: sun.misc.Unsafe or java.nio.DirectByteBuffer.(long, int) not available`. thrown by netty.
### Why are the changes needed?
After ARROW-3191, Arrow Java library requires the property `io.netty.tryReflectionSetAccessible` to be set to true for JDK >= 9. After https://github.com/apache/spark/pull/26133, JDK11 Jenkins job seem to fail.

### What changes were proposed in this pull request?
Hive support STORED AS new file format syntax:

We add a similar syntax for Spark. Here we separate to two features:
1. specify a different table provider in CREATE TABLE LIKE
2. Hive compatibility
In this PR, we address the first one:
- [ ] Using `USING provider` to specify a different table provider in CREATE TABLE LIKE.
- [ ] Using `STORED AS file_format` in CREATE TABLE LIKE to address Hive compatibility.

Use CREATE TABLE tb1 LIKE tb2 command to create an empty table tb1 based on the definition of table tb2. The most user case is to create tb1 with the same schema of tb2. But an inconvenient case here is this command also copies the FileFormat from tb2, it cannot change the input/output format and serde. Add the ability of changing file format is useful for some scenarios like upgrading a table from a low performance file format to a high performance one (parquet, orc).
### Does this PR introduce any user-facing change?
Add a new syntax based on current CTL:
```sql
CREATE TABLE tbl2 LIKE tbl [USING parquet];
```

### Why are the changes needed?
It's important to make all the commands have the same table resolution behavior, to avoid confusing end-users. e.g.

### What changes were proposed in this pull request?
`CatalogTable` to `HiveTable` will change the table's ownership. How to reproduce:
```scala
import org.apache.spark.sql.catalyst.TableIdentifier
import org.apache.spark.sql.catalyst.catalog.{CatalogStorageFormat, CatalogTable, CatalogTableType}
import org.apache.spark.sql.types.{LongType, StructType}
val identifier = TableIdentifier("spark_29498", None)
val owner = "SPARK-29498"
val newTable = CatalogTable(
identifier,
tableType = CatalogTableType.EXTERNAL,
storage = CatalogStorageFormat(
locationUri = None,
inputFormat = None,
outputFormat = None,
serde = None,
compressed = false,
properties = Map.empty),
owner = owner,
schema = new StructType().add("i", LongType, false),
provider = Some("hive"))
spark.sessionState.catalog.createTable(newTable, false)
// The owner is not SPARK-29498
println(spark.sessionState.catalog.getTableMetadata(identifier).owner)
```
This PR makes it set the `HiveTable`'s owner to `CatalogTable`'s owner if it's owner is not empty when converting `CatalogTable` to `HiveTable`.

### What changes were proposed in this pull request?
This patch proposes to delete old Hive external partition directory even the partition does not exist in Hive, when insert overwrite Hive external table partition.
### Why are the changes needed?
When insert overwrite to a Hive external table partition, if the partition does not exist, Hive will not check if the external partition directory exists or not before copying files. So if users drop the partition, and then do insert overwrite to the same partition, the partition will have both old and new data.
For example:
```scala
withSQLConf(HiveUtils.CONVERT_METASTORE_PARQUET.key -> "false") {
// test is an external Hive table.
sql("INSERT OVERWRITE TABLE test PARTITION(name='n1') SELECT 1")
sql("ALTER TABLE test DROP PARTITION(name='n1')")
sql("INSERT OVERWRITE TABLE test PARTITION(name='n1') SELECT 2")
sql("SELECT id FROM test WHERE name = 'n1' ORDER BY id") // Got both 1 and 2.
}
```
### Does this PR introduce any user-facing change?
Yes. This fix a correctness issue when users drop partition on a Hive external table partition and then insert overwrite it.

### What changes were proposed in this pull request?
When inserting a value into a column with the different data type, Spark performs type coercion. Currently, we support 3 policies for the store assignment rules: ANSI, legacy and strict, which can be set via the option "spark.sql.storeAssignmentPolicy":
1. ANSI: Spark performs the type coercion as per ANSI SQL. In practice, the behavior is mostly the same as PostgreSQL. It disallows certain unreasonable type conversions such as converting `string` to `int` and `double` to `boolean`. It will throw a runtime exception if the value is out-of-range(overflow).
2. Legacy: Spark allows the type coercion as long as it is a valid `Cast`, which is very loose. E.g., converting either `string` to `int` or `double` to `boolean` is allowed. It is the current behavior in Spark 2.x for compatibility with Hive. When inserting an out-of-range value to a integral field, the low-order bits of the value is inserted(the same as Java/Scala numeric type casting). For example, if 257 is inserted to a field of Byte type, the result is 1.
3. Strict: Spark doesn't allow any possible precision loss or data truncation in store assignment, e.g., converting either `double` to `int` or `decimal` to `double` is allowed. The rules are originally for Dataset encoder. As far as I know, no mainstream DBMS is using this policy by default.
Currently, the V1 data source uses "Legacy" policy by default, while V2 uses "Strict". This proposal is to use "ANSI" policy by default for both V1 and V2 in Spark 3.0.
### Why are the changes needed?
Following the ANSI SQL standard is most reasonable among the 3 policies.
### Does this PR introduce any user-facing change?
Yes.
The default store assignment policy is ANSI for both V1 and V2 data sources.

move the statement logical plans that were created for v2 commands to a new file `statements.scala`, under the same package of `v2Commands.scala`.
This PR also includes some minor cleanups:
1. remove `private[sql]` from `ParsedStatement` as it's in the private package.
2. remove unnecessary override of `output` and `children`.
3. add missing classdoc.
### Why are the changes needed?
Similar to https://github.com/apache/spark/pull/26111 , this is to better organize the logical plans of data source v2.
It's a bit weird to put the statements in the package `org.apache.spark.sql.catalyst.plans.logical.sql` as `sql` is not a good sub-package name in Spark SQL.

### What changes were proposed in this pull request?
Currently we deal with different `ParsedStatement` in many places and write duplicated catalog/table lookup logic. In general the lookup logic is
1. try look up the catalog by name. If no such catalog, and default catalog is not set, convert `ParsedStatement` to v1 command like `ShowDatabasesCommand`. Otherwise, convert `ParsedStatement` to v2 command like `ShowNamespaces`.
2. try look up the table by name. If no such table, fail. If the table is a `V1Table`, convert `ParsedStatement` to v1 command like `CreateTable`. Otherwise, convert `ParsedStatement` to v2 command like `CreateV2Table`.
However, since the code is duplicated we don't apply this lookup logic consistently. For example, we forget to consider the v2 session catalog in several places.
This PR centralizes the catalog/table lookup logic by 3 rules.
1. `ResolveCatalogs` (in catalyst). This rule resolves v2 catalog from the multipart identifier in SQL statements, and convert the statement to v2 command if the resolved catalog is not session catalog. If the command needs to resolve the table (e.g. ALTER TABLE), put an `UnresolvedV2Table` in the command.
2. `ResolveTables` (in catalyst). It resolves `UnresolvedV2Table` to `DataSourceV2Relation`.
3. `ResolveSessionCatalog` (in sql/core). This rule is only effective if the resolved catalog is session catalog. For commands that don't need to resolve the table, this rule converts the statement to v1 command directly. Otherwise, it converts the statement to v1 command if the resolved table is v1 table, and convert to v2 command if the resolved table is v2 table. Hopefully we can remove this rule eventually when v1 fallback is not needed anymore.
### Why are the changes needed?
Reduce duplicated code and make the catalog/table lookup logic consistent.

There wasn't any test for HashAggregateExec specifically testing this, but randomized test in ObjectHashAggregateSuite could encounter this and that's why ObjectHashAggregateSuite is flaky.
### Why are the changes needed?
Without the fix, generated code from HashAggregateExec may fail compilation.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Added new UT. Without the fix, newly added UT fails.

### What changes were proposed in this pull request?
This pr is to propagate all the SQL configurations to executors in `SQLQueryTestSuite`. When the propagation enabled in the tests, a potential bug below becomes apparent;
```
CREATE TABLE num_data (id int, val decimal(38,10)) USING parquet;
....
select sum(udf(CAST(null AS Decimal(38,0)))) from range(1,4): QueryOutput(select sum(udf(CAST(null AS Decimal(38,0)))) from range(1,4),struct<>,java.lang.IllegalArgumentException
[info] requirement failed: MutableProjection cannot use UnsafeRow for output data types: decimal(38,0)) (SQLQueryTestSuite.scala:380)
```
The root culprit is that `InterpretedMutableProjection` has incorrect validation in the interpreter mode: `validExprs.forall { case (e, _) => UnsafeRow.isFixedLength(e.dataType) }`. This validation should be the same with the condition (`isMutable`) in `HashAggregate.supportsAggregate`: https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/HashAggregateExec.scala#L1126

### What changes were proposed in this pull request?
Refactored SQL-related benchmark and made them depend on `SqlBasedBenchmark`. In particular, creation of Spark session are moved into `override def getSparkSession: SparkSession`.

Issue 2 mentioned in JIRA Spark SQL "desc formatted tablename" is not showing the header # col_name,data_type,comment , seems to be the header has been removed knowingly as part of SPARK-20954.
Issue 3:
Corrected the Last Access time, the value shall display 'UNKNOWN' as currently system wont support the last access time evaluation, since hive was setting Last access time as '0' in metastore even though spark CatalogTable last access time value set as -1. this will make the validation logic of LasAccessTime where spark sets 'UNKNOWN' value if last access time value set as -1 (means not evaluated).

### What changes were proposed in this pull request?
This patch proposes to add new tests to test the username of HiveClient to prevent changing the semantic unintentionally. The owner of Hive table has been changed back-and-forth, principal -> username -> principal, and looks like the change is not intentional. (Please refer [SPARK-28996](https://issues.apache.org/jira/browse/SPARK-28996) for more details.) This patch intends to prevent this.
This patch also renames previous HiveClientSuite(s) to HivePartitionFilteringSuite(s) as it was commented as TODO, as well as previous tests are too narrowed to test only partition filtering.

### What changes were proposed in this pull request?
Remove `InsertIntoTable` and replace it's usage by `InsertIntoStatement`
### Why are the changes needed?
`InsertIntoTable` and `InsertIntoStatement` are almost identical (except some namings). It doesn't make sense to keep 2 identical plans. After the removal of `InsertIntoTable`, the analysis process becomes:
1. parser creates `InsertIntoStatement`
2. v2 rule `ResolveInsertInto` converts `InsertIntoStatement` to v2 commands.
3. v1 rules like `DataSourceAnalysis` and `HiveAnalysis` convert `InsertIntoStatement` to v1 commands.

### What changes were proposed in this pull request?
- Remove SQLContext.createExternalTable and Catalog.createExternalTable, deprecated in favor of createTable since 2.2.0, plus tests of deprecated methods
- Remove HiveContext, deprecated in 2.0.0, in favor of `SparkSession.builder.enableHiveSupport`
- Remove deprecated KinesisUtils.createStream methods, plus tests of deprecated methods, deprecate in 2.2.0
- Remove deprecated MLlib (not Spark ML) linear method support, mostly utility constructors and 'train' methods, and associated docs. This includes methods in LinearRegression, LogisticRegression, Lasso, RidgeRegression. These have been deprecated since 2.0.0
- Remove deprecated Pyspark MLlib linear method support, including LogisticRegressionWithSGD, LinearRegressionWithSGD, LassoWithSGD
- Remove 'runs' argument in KMeans.train() method, which has been a no-op since 2.0.0
- Remove deprecated ChiSqSelector isSorted protected method
- Remove deprecated 'yarn-cluster' and 'yarn-client' master argument in favor of 'yarn' and deploy mode 'cluster', etc
Notes:
- I was not able to remove deprecated DataFrameReader.json(RDD) in favor of DataFrameReader.json(Dataset); the former was deprecated in 2.2.0, but, it is still needed to support Pyspark's .json() method, which can't use a Dataset.
- Looks like SQLContext.createExternalTable was not actually deprecated in Pyspark, but, almost certainly was meant to be? Catalog.createExternalTable was.
- I afterwards noted that the toDegrees, toRadians functions were almost removed fully in SPARK-25908, but Felix suggested keeping just the R version as they hadn't been technically deprecated. I'd like to revisit that. Do we really want the inconsistency? I'm not against reverting it again, but then that implies leaving SQLContext.createExternalTable just in Pyspark too, which seems weird.
- I *kept* LogisticRegressionWithSGD, LinearRegressionWithSGD, LassoWithSGD, RidgeRegressionWithSGD in Pyspark, though deprecated, as it is hard to remove them (still used by StreamingLogisticRegressionWithSGD?) and they are not fully removed in Scala. Maybe should not have been deprecated.
### Why are the changes needed?
Deprecated items are easiest to remove in a major release, so we should do so as much as possible for Spark 3. This does not target items deprecated 'recently' as of Spark 2.3, which is still 18 months old.
### Does this PR introduce any user-facing change?
Yes, in that deprecated items are removed from some public APIs.

## What changes were proposed in this pull request?
The `V2SessionCatalog` has 2 functionalities:
1. work as an adapter: provide v2 APIs and translate calls to the `SessionCatalog`.
2. allow users to extend it, so that they can add hooks to apply custom logic before calling methods of the builtin catalog (session catalog).
To leverage the second functionality, users must extend `V2SessionCatalog` which is an internal class. There is no doc to explain this usage.
This PR does 2 things:
1. refine the document of the config `spark.sql.catalog.session`.
2. add a public abstract class `CatalogExtension` for users to write implementations.
TODOs for followup PRs:
1. discuss if we should allow users to completely overwrite the v2 session catalog with a new one.
2. discuss to change the name of session catalog, so that it's less likely to conflict with existing namespace names.

### What changes were proposed in this pull request?
merge the `V2WriteSupportCheck` and `V2StreamingScanSupportCheck` to one rule: `TableCapabilityCheck`.

It's a little confusing to have 2 rules to check DS v2 table capability, while one rule says it checks write and another rule says it checks streaming scan. We can clearly tell it from the rule names that the batch scan check is missing.
It's better to have a centralized place for this check, with a name that clearly says it checks table capability.

### What changes were proposed in this pull request?
The Experimental and Evolving annotations are both (like Unstable) used to express that a an API may change. However there are many things in the code that have been marked that way since even Spark 1.x. Per the dev thread, anything introduced at or before Spark 2.3.0 is pretty much 'stable' in that it would not change without a deprecation cycle. Therefore I'd like to remove most of these annotations. And, remove the `:: Experimental ::` scaladoc tag too. And likewise for Python, R.
The changes below can be summarized as:
- Generally, anything introduced at or before Spark 2.3.0 has been unmarked as neither Evolving nor Experimental
- Obviously experimental items like DSv2, Barrier mode, ExperimentalMethods are untouched
- I _did_ unmark a few MLlib classes introduced in 2.4, as I am quite confident they're not going to change (e.g. KolmogorovSmirnovTest, PowerIterationClustering)
It's a big change to review, so I'd suggest scanning the list of _files_ changed to see if any area seems like it should remain partly experimental and examine those.
### Why are the changes needed?
Many of these annotations are incorrect; the APIs are de facto stable. Leaving them also makes legitimate usages of the annotations less meaningful.

No.

## What changes were proposed in this pull request?
Currently we have 2 configs to specify which v2 sources should fallback to v1 code path. One config for read path, and one config for write path.
However, I found it's awkward to work with these 2 configs:
1. for `CREATE TABLE USING format`, should this be read path or write path?
2. for `V2SessionCatalog.loadTable`, we need to return `UnresolvedTable` if it's a DS v1 or we need to fallback to v1 code path. However, at that time, we don't know if the returned table will be used for read or write.
We don't have any new features or perf improvement in file source v2. The fallback API is just a safeguard if we have bugs in v2 implementations. There are not many benefits to support falling back to v1 for read and write path separately.
This PR proposes to merge these 2 configs into one.

Sometimes when you explain a query, you will get stuck for a while. What's worse, you will get stuck again if you explain again.
This is caused by `FileSourceScanExec`:
1. In its `toString`, it needs to report the number of partitions it reads. This needs to query the hive metastore.
2. In its `outputOrdering`, it needs to get all the files. This needs to query the hive metastore.
This PR fixes by:
1. `toString` do not need to report the number of partitions it reads. We should report it via SQL metrics.
2. The `outputOrdering` is not very useful. We can only apply it if a) all the bucket columns are read. b) there is only one file in each bucket. This condition is really hard to meet, and even if we meet, sorting an already sorted file is pretty fast and avoiding the sort is not that useful. I think it's worth to give up this optimization so that explain don't need to get stuck.

This patch tries to keep consistency whenever UTF-8 charset is needed, as using `StandardCharsets.UTF_8` instead of using "UTF-8". If the String type is needed, `StandardCharsets.UTF_8.name()` is used.
This change also brings the benefit of getting rid of `UnsupportedEncodingException`, as we're providing `Charset` instead of `String` whenever possible.
This also changes some private Catalyst helper methods to operate on encodings as `Charset` objects rather than strings.

This is an alternative solution of https://github.com/apache/spark/pull/24442 . It fails the query if ambiguous self join is detected, instead of trying to disambiguate it. The problem is that, it's hard to come up with a reasonable rule to disambiguate, the rule proposed by #24442 is mostly a heuristic.
### background of the self-join problem:
This is a long-standing bug and I've seen many people complaining about it in JIRA/dev list.
A typical example:
```
val df1 = …
val df2 = df1.filter(...)
df1.join(df2, df1("a") > df2("a")) // returns empty result
```
The root cause is, `Dataset.apply` is so powerful that users think it returns a column reference which can point to the column of the Dataset at anywhere. This is not true in many cases. `Dataset.apply` returns an `AttributeReference` . Different Datasets may share the same `AttributeReference`. In the example above, `df2` adds a Filter operator above the logical plan of `df1`, and the Filter operator reserves the output `AttributeReference` of its child. This means, `df1("a")` is exactly the same as `df2("a")`, and `df1("a") > df2("a")` always evaluates to false.
### The rule to detect ambiguous column reference caused by self join:
We can reuse the infra in #24442 :
1. each Dataset has a globally unique id.
2. the `AttributeReference` returned by `Dataset.apply` carries the ID and column position(e.g. 3rd column of the Dataset) via metadata.
3. the logical plan of a `Dataset` carries the ID via `TreeNodeTag`
When self-join happens, the analyzer asks the right side plan of join to re-generate output attributes with new exprIds. Based on it, a simple rule to detect ambiguous self join is:
1. find all column references (i.e. `AttributeReference`s with Dataset ID and col position) in the root node of a query plan.
2. for each column reference, traverse the query plan tree, find a sub-plan that carries Dataset ID and the ID is the same as the one in the column reference.
3. get the corresponding output attribute of the sub-plan by the col position in the column reference.
4. if the corresponding output attribute has a different exprID than the column reference, then it means this sub-plan is on the right side of a self-join and has regenerated its output attributes. This is an ambiguous self join because the column reference points to a table being self-joined.

In case of CatalogFileIndex datasource table, sizeInBytes is always coming as default size in bytes, which is 8.0EB (Even when the user give fallBackToHdfsForStatsEnabled=true) . So, the datasource table which has CatalogFileIndex, always prefer SortMergeJoin, instead of BroadcastJoin, even though the size is below broadcast join threshold.
In this PR, In case of CatalogFileIndex table, if we enable "fallBackToHdfsForStatsEnabled=true", then the computeStatistics get the sizeInBytes from the hdfs and we get the actual size of the table. Hence, during join operation, when the table size is below broadcast threshold, it will prefer broadCastHashJoin instead of SortMergeJoin.

In #24068, IvanVergiliev fixes the issue that OrcFilters.createBuilder has exponential complexity in the height of the filter tree due to the way the check-and-build pattern is implemented.
Comparing to the approach in #24068, I propose a simple solution for the issue:
1. separate the logic of building a convertible filter tree and the actual SearchArgument builder, since the two procedures are different and their return types are different. Thus the new introduced class `ActionType`,`TrimUnconvertibleFilters` and `BuildSearchArgument` in #24068 can be dropped. The code is more readable.
2. For most of the leaf nodes, the convertible result is always Some(node), we can abstract it like this PR.
3. The code is actually small changes on the previous code. See https://github.com/apache/spark/pull/24783
## How was this patch tested?
Run the benchmark provided in #24068:
```
val schema = StructType.fromDDL("col INT")
(20 to 30).foreach { width =>
val whereFilter = (1 to width).map(i => EqualTo("col", i)).reduceLeft(Or)
val start = System.currentTimeMillis()
OrcFilters.createFilter(schema, Seq(whereFilter))
println(s"With $width filters, conversion takes ${System.currentTimeMillis() - start} ms")
}
```
Result:
```
With 20 filters, conversion takes 6 ms
With 21 filters, conversion takes 0 ms
With 22 filters, conversion takes 0 ms
With 23 filters, conversion takes 0 ms
With 24 filters, conversion takes 0 ms
With 25 filters, conversion takes 0 ms

When we use upper case partition name in Hive table, like:
```
CREATE TABLE src (KEY STRING, VALUE STRING) PARTITIONED BY (DS STRING)
```
Then, `insert into table` query doesn't work
```
INSERT INTO TABLE src PARTITION(ds) SELECT 'k' key, 'v' value, '1' ds
// or
INSERT INTO TABLE src PARTITION(DS) SELECT 'k' KEY, 'v' VALUE, '1' DS
```
```
[info] org.apache.spark.sql.AnalysisException:
org.apache.hadoop.hive.ql.metadata.Table.ValidationFailureSemanticException: Partition spec {ds=, DS=1} contains non-partition columns;
```
As Hive metastore is not case preserving and keeps partition columns with lower cased names, we lowercase column names in partition spec before passing to Hive client. But we write upper case column names in partition paths.
However, when calling `loadDynamicPartitions` to do `insert into table` for dynamic partition, Hive calculates full path spec for partition paths. So it calculates a partition spec like `{ds=, DS=1}` in above case and fails partition column validation. This patch is proposed to fix the issue by lowercasing the column names in written partition paths for Hive partitioned table.
This fix touchs `saveAsHiveFile` method, which is used in `InsertIntoHiveDirCommand` and `InsertIntoHiveTable` commands. Among them, only `InsertIntoHiveTable` passes `partitionAttributes` parameter. So I think this change only affects `InsertIntoHiveTable` command.

## What changes were proposed in this pull request?
`OrcFilters.createBuilder` has exponential complexity in the height of the filter tree due to the way the check-and-build pattern is implemented. We've hit this in production by passing a `Column` filter to Spark directly, with a job taking multiple hours for a simple set of ~30 filters. This PR changes the checking logic so that the conversion has linear complexity in the size of the tree instead of exponential in its height.
Right now, due to the way ORC `SearchArgument` works, the code is forced to do two separate phases when converting a given Spark filter to an ORC filter:
1. Check if the filter is convertible.
2. Only if the check in 1. succeeds, perform the actual conversion into the resulting ORC filter.
However, there's one detail which is the culprit in the exponential complexity: phases 1. and 2. are both done using the exact same method. The resulting exponential complexity is easiest to see in the `NOT` case - consider the following code:
```
val f1 = col("id") === lit(5)
val f2 = !f1
val f3 = !f2
val f4 = !f3
val f5 = !f4
```
Now, when we run `createBuilder` on `f5`, we get the following behaviour:
1. call `createBuilder(f4)` to check if the child `f4` is convertible
2. call `createBuilder(f4)` to actually convert it
This seems fine when looking at a single level, but what actually ends up happening is:
- `createBuilder(f3)` will then recursively be called 4 times - 2 times in step 1., and two times in step 2.
- `createBuilder(f2)` will be called 8 times - 4 times in each top-level step, 2 times in each sub-step.
- `createBuilder(f1)` will be called 16 times.
As a result, having a tree of height > 30 leads to billions of calls to `createBuilder`, heap allocations, and so on and can take multiple hours.
The way this PR solves this problem is by separating the `check` and `convert` functionalities into separate functions. This way, the call to `createBuilder` on `f5` above would look like this:
1. call `isConvertible(f4)` to check if the child `f4` is convertible - amortized constant complexity
2. call `createBuilder(f4)` to actually convert it - linear complexity in the size of the subtree.
This way, we get an overall complexity that's linear in the size of the filter tree, allowing us to convert tree with 10s of thousands of nodes in milliseconds.
The reason this split (`check` and `build`) is possible is that the checking never actually depends on the actual building of the filter. The `check` part of `createBuilder` depends mainly on:
- `isSearchableType` for leaf nodes, and
- `check`-ing the child filters for composite nodes like NOT, AND and OR.
Situations like the `SearchArgumentBuilder` throwing an exception while building the resulting ORC filter are not handled right now - they just get thrown out of the class, and this change preserves this behaviour.
This PR extracts this part of the code to a separate class which allows the conversion to make very efficient checks to confirm that a given child is convertible before actually converting it.
Results:
Before:
- converting a skewed tree with a height of ~35 took about 6-7 hours.
- converting a skewed tree with hundreds or thousands of nodes would be completely impossible.
Now:
- filtering against a skewed tree with a height of 1500 in the benchmark suite finishes in less than 10 seconds.

SELECT INTERVAL '23:59:59.155' HOUR TO SECOND
```
Although we can add a new function for this pattern, we had better extend the existing code to handle a missing day case. So, the following is also supported.
```sql
SELECT INTERVAL '23:59:59.155' DAY TO SECOND
SELECT INTERVAL '1 23:59:59.155' HOUR TO SECOND
```
Currently Vertica/Teradata/Postgresql/SQL Server have fully support of below interval functions.
- interval ... year to month
- interval ... day to hour
- interval ... day to minute
- interval ... day to second
- interval ... hour to minute
- interval ... hour to second
- interval ... minute to second

## What changes were proposed in this pull request?
The new Spark ThriftServer SparkGetTablesOperation implemented in https://github.com/apache/spark/pull/22794 does a catalog.getTableMetadata request for every table. This can get very slow for large schemas (~50ms per table with an external Hive metastore).
Hive ThriftServer GetTablesOperation uses HiveMetastoreClient.getTableObjectsByName to get table information in bulk, but we don't expose that through our APIs that go through Hive -> HiveClientImpl (HiveClient) -> HiveExternalCatalog (ExternalCatalog) -> SessionCatalog.
If we added and exposed getTableObjectsByName through our catalog APIs, we could resolve that performance problem in SparkGetTablesOperation.

Hive 3.1.1's `CommandProcessor` have 2 changes:

We can disable `hive.query.reexecution.enabled` to workaround this change.
2. [HIVE-18238](http://issues.apache.org/jira/browse/HIVE-18238)(Hive 3.0.0) changed the `Driver.close()` function return type. We can workaround it by ` driver.getClass.getMethod("close").invoke(driver)`
So Hive 3.1 metastore could support `HiveClientImpl.runHive` after this pr.

## What changes were proposed in this pull request?
When turning a Dataset to another Dataset, Spark will up cast the fields in the original Dataset to the type of corresponding fields in the target DataSet.
However, the current upcast behavior is a little weird, we don't allow up casting from string to numeric, but allow non-numeric types as the target, like boolean, date, etc.
As a result, `Seq("str").toDS.as[Int]` fails, but `Seq("str").toDS.as[Boolean]` works and throw NPE during execution.
The motivation of the up cast is to prevent things like runtime NPE, it's more reasonable to make up cast stricter.
This PR does 2 things:
1. rename `Cast.canSafeCast` to `Cast.canUpcast`, and support complex typres
2. remove `Cast.mayTruncate` and replace it with `!Cast.canUpcast`
Note that, the up cast change also affects persistent view resolution. But since we don't support changing column types of an existing table, there is no behavior change here.

If we refresh a cached table, the table cache will be first uncached and then recache (lazily). Currently, the logic is embedded in CatalogImpl.refreshTable method.
The current implementation does not preserve the cache name and storage level. As a result, cache name and cache level could be changed after a REFERSH. IMHO, it is not what a user would expect.
I would like to fix this behavior by first save the cache name and storage level for recaching the table.
Two unit tests are added to make sure cache name is unchanged upon table refresh. Before applying this patch, the test created for qualified case would fail.

If we set `hive.exec.stagingdir=.test-staging\tmp`,
But the staging directory is still `.hive-staging` on Windows OS.
Reasons for failure:
Test code:
```
val path = new Path("C:\\test\\hivetable")
println("path.toString: " + path.toString)
println("path.toUri.getPath: " + path.toUri.getPath)
```
Output:
```
path.toString: C:/test/hivetable
path.toUri.getPath: /C:/test/hivetable
```
We can see that `path.toUri.getPath` has one more separator than `path.toString`, and the separator is ' / ', not ' \ '
So `stagingPathName.stripPrefix(inputPathName).stripPrefix(File.separator).startsWith(".")` will return false

## What changes were proposed in this pull request?
Currently, in `ParquetFilters` and `OrcFilters`, if the child predicate of `Or` operator can't be entirely pushed down, the predicates will be thrown away.
In fact, the conjunctive predicates under `Or` operators can be partially pushed down.
For example, says `a` and `b` are convertible, while `c` can't be pushed down, the predicate
`a or (b and c)`
can be converted as
`(a or b) and (a or c)`
We can still push down `(a or b)`.
We can't push down disjunctive predicates only when one of its children is not partially convertible.
This PR also improve the filter pushing down logic in `DataSourceV2Strategy`. With partial filter push down in `Or` operator, the result of `pushedFilters()` might not exist in the mapping `translatedFilterToExpr`. To fix it, this PR changes the mapping `translatedFilterToExpr` as leaf filter expression to `sources.filter`, and later on rebuild the whole expression with the mapping.

This is a followup of https://github.com/apache/spark/pull/24144 . #24144 missed one case: when hash aggregate fallback to sort aggregate, the life cycle of UDAF is: INIT -> UPDATE -> MERGE -> FINISH.
However, not all Hive UDAF can support it. 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)). The buffer for UPDATE may not support MERGE.
This PR updates the Hive UDAF adapter in Spark to support INIT -> UPDATE -> MERGE -> FINISH, by turning it to INIT -> UPDATE -> FINISH + IINIT -> MERGE -> FINISH.

I want to get rid of as much use of `scala.language.existentials` as possible for 3.0. It's a complicated language feature that generates warnings unless this value is imported. It might even be on the way out of Scala: https://contributors.scala-lang.org/t/proposal-to-remove-existential-types-from-the-language/2785
For Spark, it comes up mostly where the code plays fast and loose with generic types, not the advanced situations you'll often see referenced where this feature is explained. For example, it comes up in cases where a function returns something like `(String, Class[_])`. Scala doesn't like matching this to any other instance of `(String, Class[_])` because doing so requires inferring the existence of some type that satisfies both. Seems obvious if the generic type is a wildcard, but, not technically something Scala likes to let you get away with.
This is a large PR, and it only gets rid of _most_ instances of `scala.language.existentials`. The change should be all compile-time and shouldn't affect APIs or logic.
Many of the changes simply touch up sloppiness about generic types, making the known correct value explicit in the code.
Some fixes involve being more explicit about the existence of generic types in methods. For instance, `def foo(arg: Class[_])` seems innocent enough but should really be declared `def foo[T](arg: Class[T])` to let Scala select and fix a single type when evaluating calls to `foo`.
For kind of surprising reasons, this comes up in places where code evaluates a tuple of things that involve a generic type, but is OK if the two parts of the tuple are evaluated separately.
One key change was altering `Utils.classForName(...): Class[_]` to the more correct `Utils.classForName[T](...): Class[T]`. This caused a number of small but positive changes to callers that otherwise had to cast the result.
In several tests, `Dataset[_]` was used where `DataFrame` seems to be the clear intent.
Finally, in a few cases in MLlib, the return type `this.type` was used where there are no subclasses of the class that uses it. This really isn't needed and causes issues for Scala reasoning about the return type. These are just changed to be concrete classes as return types.
After this change, we have only a few classes that still import `scala.language.existentials` (because modifying them would require extensive rewrites to fix) and no build warnings.

In the rule `PreprocessTableCreation`, if an existing table is appended with a different provider, the action will fail.
Currently, there are two implementations for file sources and creating a table with file source V2 will always fall back to V1 FileFormat. We should consider the following cases as valid:
1. Appending a table with file source V2 provider using the v1 file format
2. Appending a table with v1 file format provider using file source V2 format

In the first PR for file source V2, there was a rule for falling back Orc V2 table to OrcFileFormat: https://github.com/apache/spark/pull/23383/files#diff-57e8244b6964e4f84345357a188421d5R34
As we are migrating more file sources to data source V2, we should make the rule more generic. This PR proposes to:
1. Rename the rule `FallbackOrcDataSourceV2 ` to `FallBackFileSourceV2`.The name is more generic. And we use "fall back" as verb, while "fallback" is noun.
2. Rename the method `fallBackFileFormat` in `FileDataSourceV2` to `fallbackFileFormat`. Here we should use "fallback" as noun.
3. Add new method `fallbackFileFormat` in `FileTable`. This is for falling back to V1 in rule `FallbackOrcDataSourceV2 `.

## What changes were proposed in this pull request?
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 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.
For more information, see the [mailing list thread](https://lists.apache.org/thread.html/54f4e1929ceb9a2b0cac7cb058000feb8de5d6c667b2e0950804c613%3Cdev.spark.apache.org%3E).

Currently, users meet job abortions while creating a table using the Hive serde "STORED AS" with invalid column names. We had better prevent this by raising **AnalysisException** with a guide to use aliases instead like Paquet data source tables.
thus making compatible with error message shown while creating Parquet/ORC native table.

```java
public class SqlDemo {
public static void main(final String[] args) throws Exception {
SparkConf conf = new SparkConf().setAppName("spark-sql-demo");
JavaSparkContext sc = new JavaSparkContext(conf);
SparkSession ss = SparkSession.builder().enableHiveSupport().getOrCreate();
ss.sql("show databases").show();
}
}
```
Before https://issues.apache.org/jira/browse/SPARK-20946, the demo above point to the right hive metastore if the hive-site.xml is present. But now it can only point to the default in-memory one.
Catalog is now as a variable shared across SparkSessions, it is instantiated with SparkContext's conf. After https://issues.apache.org/jira/browse/SPARK-20946, Session level configs are not pass to SparkContext's conf anymore, so the enableHiveSupport API takes no affect on the catalog instance.
You can set spark.sql.catalogImplementation=hive application wide to solve the problem, or never create a sc before you call SparkSession.builder().enableHiveSupport().getOrCreate()
Here we respect the SparkSession level configuration at the first time to generate catalog within SharedState
## How was this patch tested?
1. add ut
2. manually
```scala
test("enableHiveSupport has right to determine the catalog while using an existing sc") {
val conf = new SparkConf().setMaster("local").setAppName("SharedState Test")
val sc = SparkContext.getOrCreate(conf)
val ss = SparkSession.builder().enableHiveSupport().getOrCreate()
assert(ss.sharedState.externalCatalog.unwrapped.isInstanceOf[HiveExternalCatalog],
"The catalog should be hive ")
val ss2 = SparkSession.builder().getOrCreate()
assert(ss2.sharedState.externalCatalog.unwrapped.isInstanceOf[HiveExternalCatalog],
"The catalog should be shared across sessions")
}
```
Without this fix, the above test will fail.
You can apply it to `org.apache.spark.sql.hive.HiveSharedStateSuite`,
and run,
```sbt
./build/sbt -Phadoop-2.7 -Phive "hive/testOnly org.apache.spark.sql.hive.HiveSharedStateSuite"
```
to verify.

Run Spark-Sql job use transform features(`ScriptTransformationExec`) with config `spark.speculation = true`, sometimes job fails and we found many Executor Dead through `Executor Tab`, through analysis log and code we found :
`ScriptTransformationExec` start a new thread(`ScriptTransformationWriterThread`), the new thread is very likely to throw `TaskKilledException`(from iter.map.foreach part) when speculation is on, this exception will captured by `SparkUncaughtExceptionHandler` which registered during Executor start, `SparkUncaughtExceptionHandler` will call `System.exit (SparkExitCode.UNCAUGHT_EXCEPTION)` to shutdown `Executor`, this is unexpected.
We should not kill the executor just because `ScriptTransformationWriterThread` fails. log the error(not only `TaskKilledException`) instead of throwing it is enough, Exception already pass to `ScriptTransformationExec` and handle by `TaskRunner`.
## How was this patch tested?
Register `TestUncaughtExceptionHandler` to test case in `ScriptTransformationSuite`, then assert there is no Uncaught Exception handled.
Before this patch "script transformation should not swallow errors from upstream operators (no serde)" and "script transformation should not swallow errors from upstream operators (with serde)" throwing `IllegalArgumentException` and handle by `TestUncaughtExceptionHandler` .

When we read a hive table and create RDDs in `TableReader`, it'll throw exception `java.lang.ClassCastException: org.apache.hadoop.mapreduce.lib.input.TextInputFormat cannot be cast to org.apache.hadoop.mapred.InputFormat` if the input format class of the table is from mapreduce package.

When reading from empty tables, the optimization `OptimizeMetadataOnlyQuery` may return wrong results:
```
sql("CREATE TABLE t (col1 INT, p1 INT) USING PARQUET PARTITIONED BY (p1)")
sql("INSERT INTO TABLE t PARTITION (p1 = 5) SELECT ID FROM range(1, 1)")
sql("SELECT MAX(p1) FROM t")
```
The result is supposed to be `null`. However, with the optimization the result is `5`.
The rule is originally ported from https://issues.apache.org/jira/browse/HIVE-1003 in #13494. In Hive, the rule is disabled by default in a later release(https://issues.apache.org/jira/browse/HIVE-15397), due to the same problem.
It is hard to completely avoid the correctness issue. Because data sources like Parquet can be metadata-only. Spark can't tell whether it is empty or not without actually reading it. This PR disable the optimization by default.

## What changes were proposed in this pull request?
The explain output of the Hive CTAS command, regardless of whether it's actually writing via Hive's SerDe or converted into using Spark's data source, would always show that it's using `InsertIntoHiveTable` because it's hardcoded.
e.g.
```
Execute OptimizedCreateHiveTableAsSelectCommand [Database:default, TableName: foo, InsertIntoHiveTable]
```
This CTAS is converted into using Spark's data source, but it still says `InsertIntoHiveTable` in the explain output.
It's better to show the actual class name of the writing command used. For the example above, it'd be:
```
Execute OptimizedCreateHiveTableAsSelectCommand [Database:default, TableName: foo, InsertIntoHadoopFsRelationCommand]
```

- Scan ColumnarBatch

In https://github.com/apache/spark/pull/23043 , we introduced a behavior change: Spark users are not able to distinguish 0.0 and -0.0 anymore.
This PR proposes an alternative fix to the original bug, to retain the difference between 0.0 and -0.0 inside Spark.
The idea is, we can rewrite the window partition key, join key and grouping key during logical phase, to normalize the special floating numbers. Thus only operators care about special floating numbers need to pay the perf overhead, and end users can distinguish -0.0.

## What changes were proposed in this pull request?
Currently Spark table maintains Hive catalog storage format, so that Hive client can read it. In `HiveSerDe.scala`, Spark uses a mapping from its data source to HiveSerde. The mapping is old, we need to update with latest canonical name of Parquet and Orc FileFormat.
Otherwise the following queries will result in wrong Serde value in Hive table(default value `org.apache.hadoop.mapred.SequenceFileInputFormat`), and Hive client will fail to read the output table:
```
df.write.format("org.apache.spark.sql.execution.datasources.parquet.ParquetFileFormat").saveAsTable(..)
```
```
df.write.format("org.apache.spark.sql.execution.datasources.orc.OrcFileFormat").saveAsTable(..)

In Spark 2.3.0 and previous versions, Hive CTAS command will convert to use data source to write data into the table when the table is convertible. This behavior is controlled by the configs like HiveUtils.CONVERT_METASTORE_ORC and HiveUtils.CONVERT_METASTORE_PARQUET.
In 2.3.1, we drop this optimization by mistake in the PR [SPARK-22977](https://github.com/apache/spark/pull/20521/files#r217254430). Since that Hive CTAS command only uses Hive Serde to write data.

This is a Hadoop issue that fails to parse some java.version. It has been fixed from Hadoop-2.7.4(see [HADOOP-14586](https://issues.apache.org/jira/browse/HADOOP-14586)).
Note, Hadoop-2.7.5 or upper have another problem with Spark ([SPARK-25330](https://issues.apache.org/jira/browse/SPARK-25330)). So upgrading to 2.7.4 would be fine for now.

This restores scaladoc artifact generation, which got dropped with the Scala 2.12 update. The change looks large, but is almost all due to needing to make the InterfaceStability annotations top-level classes (i.e. `InterfaceStability.Stable` -> `Stable`), unfortunately. A few inner class references had to be qualified too.
Lots of scaladoc warnings now reappear. We can choose to disable generation by default and enable for releases, later.

Currently, Spark writes Spark version number into Hive Table properties with `spark.sql.create.version`.
```
parameters:{
spark.sql.sources.schema.part.0={
"type":"struct",
"fields":[{"name":"a","type":"integer","nullable":true,"metadata":{}}]
},
transient_lastDdlTime=1541142761,
spark.sql.sources.schema.numParts=1,
spark.sql.create.version=2.4.0
}
```
This PR aims to write Spark versions to ORC/Parquet file metadata with `org.apache.spark.sql.create.version` because we used `org.apache.` prefix in Parquet metadata already. It's different from Hive Table property key `spark.sql.create.version`, but it seems that we cannot change Hive Table property for backward compatibility.
After this PR, ORC and Parquet file generated by Spark will have the following metadata.
**ORC (`native` and `hive` implmentation)**
```
$ orc-tools meta /tmp/o
File Version: 0.12 with ...
...
User Metadata:
org.apache.spark.sql.create.version=3.0.0

**PARQUET**

Without this PR some UDAFs like `GenericUDAFPercentileApprox` can throw an exception because expecting a constant parameter (object inspector) as a particular argument.
The exception is thrown because `toPrettySQL` call in `ResolveAliases` analyzer rule transforms a `Literal` parameter to a `PrettyAttribute` which is then transformed to an `ObjectInspector` instead of a `ConstantObjectInspector`.
The exception comes from `getEvaluator` method of `GenericUDAFPercentileApprox` that actually shouldn't be called during `toPrettySQL` transformation. The reason why it is called are the non lazy fields in `HiveUDAFFunction`.
This PR makes all fields of `HiveUDAFFunction` lazy.

According to the SQL standard, when a query contains `HAVING`, it indicates an aggregate operator. For more details please refer to https://blog.jooq.org/2014/12/04/do-you-really-understand-sqls-group-by-and-having-clauses/
However, in Spark SQL parser, we treat HAVING as a normal filter when there is no GROUP BY, which breaks SQL semantic and lead to wrong result. This PR fixes the parser.

This PR can correctly cause assertion failure when incorrect nullable of DataType in the result is generated by a target function to be tested.
Let us think the following example. In the future, a developer would write incorrect code that returns unexpected result. We have to correctly cause fail in this test since `valueContainsNull=false` while `expr` includes `null`. However, without this PR, this test passes. This PR can correctly cause fail.
```
test("test TARGETFUNCTON") {
val expr = TARGETMAPFUNCTON()
// expr = UnsafeMap(3 -> 6, 7 -> null)
// expr.dataType = (IntegerType, IntegerType, false)
expected = Map(3 -> 6, 7 -> null)
checkEvaluation(expr, expected)
```
In [`checkEvaluationWithUnsafeProjection`](https://github.com/apache/spark/blob/master/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/ExpressionEvalHelper.scala#L208-L235), the results are compared using `UnsafeRow`. When the given `expected` is [converted](https://github.com/apache/spark/blob/master/sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/ExpressionEvalHelper.scala#L226-L227)) to `UnsafeRow` using the `DataType` of `expr`.
```
val expectedRow = UnsafeProjection.create(Array(expression.dataType, expression.dataType)).apply(lit)
```
In summary, `expr` is `[0,1800000038,5000000038,18,2,0,700000003,2,0,6,18,2,0,700000003,2,0,6]` with and w/o this PR. `expected` is converted to
* w/o this PR, `[0,1800000038,5000000038,18,2,0,700000003,2,0,6,18,2,0,700000003,2,0,6]`
* with this PR, `[0,1800000038,5000000038,18,2,0,700000003,2,2,6,18,2,0,700000003,2,2,6]`
As a result, w/o this PR, the test unexpectedly passes.
This is because, w/o this PR, based on given `dataType`, generated code of projection for `expected` avoids to set nullbit.
```
// tmpInput_2 is expected
/* 155 */ for (int index_1 = 0; index_1 < numElements_1; index_1++) {
/* 156 */ mutableStateArray_1[1].write(index_1, tmpInput_2.getInt(index_1));
/* 157 */ }
```
With this PR, generated code of projection for `expected` always checks whether nullbit should be set by `isNullAt`
```
// tmpInput_2 is expected
/* 161 */ for (int index_1 = 0; index_1 < numElements_1; index_1++) {
/* 162 */
/* 163 */ if (tmpInput_2.isNullAt(index_1)) {
/* 164 */ mutableStateArray_1[1].setNull4Bytes(index_1);
/* 165 */ } else {
/* 166 */ mutableStateArray_1[1].write(index_1, tmpInput_2.getInt(index_1));
/* 167 */ }
/* 168 */
/* 169 */ }

Before ORC 1.5.3, `orc.dictionary.key.threshold` and `hive.exec.orc.dictionary.key.size.threshold` are applied for all columns. This has been a big huddle to enable dictionary encoding. From ORC 1.5.3, `orc.column.encoding.direct` is added to enforce direct encoding selectively in a column-wise manner. This PR aims to add that feature by upgrading ORC from 1.5.2 to 1.5.3.
The followings are the patches in ORC 1.5.3 and this feature is the only one related to Spark directly.
```

This PR adds a rule to force `.toLowerCase(Locale.ROOT)` or `toUpperCase(Locale.ROOT)`.
It produces an error as below:
```
[error] Are you sure that you want to use toUpperCase or toLowerCase without the root locale? In most cases, you
[error] should use toUpperCase(Locale.ROOT) or toLowerCase(Locale.ROOT) instead.
[error] If you must use toUpperCase or toLowerCase without the root locale, wrap the code block with
[error] // scalastyle:off caselocale
[error] .toUpperCase
[error] .toLowerCase
[error] // scalastyle:on caselocale
```
This PR excludes the cases above for SQL code path for external calls like table name, column name and etc.
For test suites, or when it's clear there's no locale problem like Turkish locale problem, it uses `Locale.ROOT`.
One minor problem is, `UTF8String` has both methods, `toLowerCase` and `toUpperCase`, and the new rule detects them as well. They are ignored.

This PR aims to prevent test slowdowns at `HiveExternalCatalogVersionsSuite` by using the latest Apache Spark 2.3.2 link because the Apache mirrors will remove the old Spark 2.3.1 binaries eventually. `HiveExternalCatalogVersionsSuite` will not fail because [SPARK-24813](https://issues.apache.org/jira/browse/SPARK-24813) implements a fallback logic. However, it will cause many trials and fallbacks in all builds over `branch-2.3/branch-2.4/master`. We had better fix this issue.

**Description from the JIRA :**
Currently, to collect the statistics of all the columns, users need to specify the names of all the columns when calling the command "ANALYZE TABLE ... FOR COLUMNS...". This is not user friendly. Instead, we can introduce the following SQL command to achieve it without specifying the column names.
```
ANALYZE TABLE [db_name.]tablename COMPUTE STATISTICS FOR ALL COLUMNS;

Currently, Spark has 7 `withTempPath` and 6 `withSQLConf` functions. This PR aims to remove duplicated and inconsistent code and reduce them to the following meaningful implementations.
**withTempPath**

**withSQLConf**
- `SQLHelper.withSQLConf`: The one which was used in `PlanTest`.
- `ExecutorSideSQLConfSuite.withSQLConf`: The one which doesn't throw `AnalysisException` on StaticConf changes.
- `SQLTestUtils.withSQLConf`: The one which overrides intentionally to change the active session.

Currently there are two classes with the same naming BenchmarkBase:
1. `org.apache.spark.util.BenchmarkBase`
2. `org.apache.spark.sql.execution.benchmark.BenchmarkBase`
This is very confusing. And the benchmark object `org.apache.spark.sql.execution.benchmark.FilterPushdownBenchmark` is using the one in `org.apache.spark.util.BenchmarkBase`, while there is another class `BenchmarkBase` in the same package of it...
Here I propose:
1. the package `org.apache.spark.util.BenchmarkBase` should be in test package of core module. Move it to package `org.apache.spark.benchmark` .
2. Move `org.apache.spark.util.Benchmark` to test package of core module. Move it to package `org.apache.spark.benchmark` .
3. Rename the class `org.apache.spark.sql.execution.benchmark.BenchmarkBase` as `BenchmarkWithCodegen`

## What changes were proposed in this pull request?
Before Apache Spark 2.3, table properties were ignored when writing data to a hive table(created with STORED AS PARQUET/ORC syntax), because the compression configurations were not passed to the FileFormatWriter in hadoopConf. Then it was fixed in #20087. But actually for CTAS with USING PARQUET/ORC syntax, table properties were ignored too when convertMastore, so the test case for CTAS not supported.
Now it has been fixed in #20522 , the test case should be enabled too.

`HiveExternalCatalogVersionsSuite` Scala-2.12 test has been failing due to class path issue. It is marked as `ABORTED` because it fails at `beforeAll` during data population stage.
- https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-master-test-maven-hadoop-2.7-ubuntu-scala-2.12/
```
org.apache.spark.sql.hive.HiveExternalCatalogVersionsSuite *** ABORTED ***
Exception encountered when invoking run on a nested suite - spark-submit returned with exit code 1.
```
The root cause of the failure is that `runSparkSubmit` mixes 2.4.0-SNAPSHOT classes and old Spark (2.1.3/2.2.2/2.3.1) together during `spark-submit`. This PR aims to provide `non-test` mode execution mode to `runSparkSubmit` by removing the followings.
- SPARK_TESTING
- SPARK_SQL_TESTING
- SPARK_PREPEND_CLASSES
- SPARK_DIST_CLASSPATH
Previously, in the class path, new Spark classes are behind the old Spark classes. So, new ones are unseen. However, Spark 2.4.0 reveals this bug due to the recent data source class changes.
## How was this patch tested?
Manual test. After merging, it will be tested via Jenkins.

Let's see the follow example:
```
val location = "/tmp/t"
val df = spark.range(10).toDF("id")
df.write.format("parquet").saveAsTable("tbl")
spark.sql("CREATE VIEW view1 AS SELECT id FROM tbl")
spark.sql(s"CREATE TABLE tbl2(ID long) USING parquet location $location")
spark.sql("INSERT OVERWRITE TABLE tbl2 SELECT ID FROM view1")
println(spark.read.parquet(location).schema)
spark.table("tbl2").show()
```
The output column name in schema will be `id` instead of `ID`, thus the last query shows nothing from `tbl2`.
By enabling the debug message we can see that the output naming is changed from `ID` to `id`, and then the `outputColumns` in `InsertIntoHadoopFsRelationCommand` is changed in `RemoveRedundantAliases`.
**To guarantee correctness**, we should change the output columns from `Seq[Attribute]` to `Seq[String]` to avoid its names being replaced by optimizer.
I will fix project elimination related rules in https://github.com/apache/spark/pull/22311 after this one.

**Problem statement**
load data command with hdfs file paths consists of wild card strings like * are not working
eg:
"load data inpath 'hdfs://hacluster/user/ext* into table t1"
throws Analysis exception while executing this query
**Analysis -**
Currently fs.exists() API which is used for path validation in load command API cannot resolve the path with wild card pattern, To mitigate this problem i am using globStatus() API another api which can resolve the paths with hdfs supported wildcards like *,? etc(inline with hive wildcard support).
**Improvement identified as part of this issue -**
Currently system wont support wildcard character to be used for folder level path in a local file system. This PR has handled this scenario, the same globStatus API will unify the validation logic of local and non local file systems, this will ensure the behavior consistency between the hdfs and local file path in load command.
with this improvement user will be able to use a wildcard character in folder level path of a local file system in load command inline with hive behaviour, in older versions user can use wildcards only in file path of the local file system if they use in folder path system use to give an error by mentioning that not supported.
eg: load data local inpath '/localfilesystem/folder* into table t1
## How was this patch tested?
a) Manually tested by executing test-cases in HDFS yarn cluster. Reports is been attached in below section.
b) Existing test-case can verify the impact and functionality for local file path scenarios
c) A test-case is been added for verifying the functionality when wild card is been used in folder level path of a local file system
## Test Results
Note: all ip's were updated to localhost for security reasons.

## What changes were proposed in this pull request?
[SPARK-25126] (https://issues.apache.org/jira/browse/SPARK-25126)
reports loading a large number of orc files consumes a lot of memory
in both 2.0 and 2.3. The issue is caused by creating a Reader for every
orc file in order to infer the schema.
In OrFileOperator.ReadSchema, a Reader is created for every file
although only the first valid one is used. This uses significant
amount of memory when there `paths` have a lot of files. In 2.3
a different code path (OrcUtils.readSchema) is used for inferring
schema for orc files. This commit changes both functions to create
Reader lazily.

## What changes were proposed in this pull request?
This pr proposed to show RDD/relation names in RDD/Hive table scan nodes.
This change made these names show up in the webUI and explain results.
For example;
```
scala> sql("CREATE TABLE t(c1 int) USING hive")
scala> sql("INSERT INTO t VALUES(1)")
scala> spark.table("t").explain()
== Physical Plan ==
Scan hive default.t [c1#8], HiveTableRelation `default`.`t`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, [c1#8]
^^^^^^^^^^^

## 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.

## What changes were proposed in this pull request?
A logical `Limit` is performed physically by two operations `LocalLimit` and `GlobalLimit`.
Most of time, we gather all data into a single partition in order to run `GlobalLimit`. If we use a very big limit number, shuffling data causes performance issue also reduces parallelism.
We can avoid shuffling into single partition if we don't care data ordering. This patch implements this idea by doing a map stage during global limit. It collects the info of row numbers at each partition. For each partition, we locally retrieves limited data without any shuffling to finish this global limit.
For example, we have three partitions with rows (100, 100, 50) respectively. In global limit of 100 rows, we may take (34, 33, 33) rows for each partition locally. After global limit we still have three partitions.
If the data partition has certain ordering, we can't distribute required rows evenly to each partitions because it could change data ordering. But we still can avoid shuffling.
## How was this patch tested?

## What changes were proposed in this pull request?
The design details is attached to the JIRA issue [here](https://drive.google.com/file/d/1zKm3aNZ3DpsqIuoMvRsf0kkDkXsAasxH/view)
High level overview of the changes are:
- Enhance the qualifier to be more than one string
- Add support to store the qualifier. Enhance the lookupRelation to keep the qualifier appropriately.
- Enhance the table matching column resolution algorithm to account for qualifier being more than a string.
- Enhance the table matching algorithm in UnresolvedStar.expand
- Ensure that we continue to support select t1.i1 from db1.t1
## How was this patch tested?
- New tests are added.
- Several test scenarios were added in a separate [test pr 17067](https://github.com/apache/spark/pull/17067). The tests that were not supported earlier are marked with TODO markers and those are now supported with the code changes here.
- Existing unit tests ( hive, catalyst and sql) were run successfully.

## What changes were proposed in this pull request?
This PR addresses issues 2,3 in this [document](https://docs.google.com/document/d/1fbkjEL878witxVQpOCbjlvOvadHtVjYXeB-2mgzDTvk).
* We modified the closure cleaner to identify closures that are implemented via the LambdaMetaFactory mechanism (serializedLambdas) (issue2).
* We also fix the issue due to scala/bug#11016. There are two options for solving the Unit issue, either add () at the end of the closure or use the trick described in the doc. Otherwise overloading resolution does not work (we are not going to eliminate either of the methods) here. Compiler tries to adapt to Unit and makes these two methods candidates for overloading, when there is polymorphic overloading there is no ambiguity (that is the workaround implemented). This does not look that good but it serves its purpose as we need to support two different uses for method: `addTaskCompletionListener`. One that passes a TaskCompletionListener and one that passes a closure that is wrapped with a TaskCompletionListener later on (issue3).
Note: regarding issue 1 in the doc the plan is:
> Do Nothing. Don’t try to fix this as this is only a problem for Java users who would want to use 2.11 binaries. In that case they can cast to MapFunction to be able to utilize lambdas. In Spark 3.0.0 the API should be simplified so that this issue is removed.

## What changes were proposed in this pull request?
When we do an average, the result is computed dividing the sum of the values by their count. In the case the result is a DecimalType, the way we are casting/managing the precision and scale is not really optimized and it is not coherent with what we do normally.
In particular, a problem can happen when the `Divide` operand returns a result which contains a precision and scale different by the ones which are expected as output of the `Divide` operand. In the case reported in the JIRA, for instance, the result of the `Divide` operand is a `Decimal(38, 36)`, while the output data type for `Divide` is 38, 22. This is not an issue when the `Divide` is followed by a `CheckOverflow` or a `Cast` to the right data type, as these operations return a decimal with the defined precision and scale. Despite in the `Average` operator we do have a `Cast`, this may be bypassed if the result of `Divide` is the same type which it is casted to, hence the issue reported in the JIRA may arise.
The PR proposes to use the normal rules/handling of the arithmetic operators with Decimal data type, so we both reuse the existing code (having a single logic for operations between decimals) and we fix this problem as the result is always guarded by `CheckOverflow`.

## What changes were proposed in this pull request?
AnalysisBarrier was introduced in SPARK-20392 to improve analysis speed (don't re-analyze nodes that have already been analyzed).
Before AnalysisBarrier, we already had some infrastructure in place, with analysis specific functions (resolveOperators and resolveExpressions). These functions do not recursively traverse down subplans that are already analyzed (with a mutable boolean flag _analyzed). The issue with the old system was that developers started using transformDown, which does a top-down traversal of the plan tree, because there was not top-down resolution function, and as a result analyzer performance became pretty bad.
In order to fix the issue in SPARK-20392, AnalysisBarrier was introduced as a special node and for this special node, transform/transformUp/transformDown don't traverse down. However, the introduction of this special node caused a lot more troubles than it solves. This implicit node breaks assumptions and code in a few places, and it's hard to know when analysis barrier would exist, and when it wouldn't. Just a simple search of AnalysisBarrier in PR discussions demonstrates it is a source of bugs and additional complexity.
Instead, this pull request removes AnalysisBarrier and reverts back to the old approach. We added infrastructure in tests that fail explicitly if transform methods are used in the analyzer.

Added a test suite AnalysisHelperSuite for testing the resolve* methods and transform* methods.

In the PR, I propose to extend the `StructType`/`StructField` classes by new method `toDDL` which converts a value of the `StructType`/`StructField` type to a string formatted in DDL style. The resulted string can be used in a table creation.
The `toDDL` method of `StructField` is reused in `SHOW CREATE TABLE`. In this way the PR fixes the bug of unquoted names of nested fields.

## What changes were proposed in this pull request?
We get a NPE when we have a filter on a partition column of the form `col in (x, null)`. This is due to the filter converter in HiveShim not handling `null`s correctly. This patch fixes this bug while still pushing down as much of the partition pruning predicates as possible, by filtering out `null`s from any `in` predicate. Since Hive only supports very simple partition pruning filters, this change should preserve correctness.

## What changes were proposed in this pull request?
With https://github.com/apache/spark/pull/21389, data source schema is validated on driver side before launching read/write tasks.
However,
1. Putting all the validations together in `DataSourceUtils` is tricky and hard to maintain. On second thought after review, I find that the `OrcFileFormat` in hive package is not matched, so that its validation wrong.
2. `DataSourceUtils.verifyWriteSchema` and `DataSourceUtils.verifyReadSchema` is not supposed to be called in every file format. We can move them to some upper entry.
So, I propose we can add a new method `validateDataType` in FileFormat. File format implementation can override the method to specify its supported/non-supported data types.
Although we should focus on data source V2 API, `FileFormat` should remain workable for some time. Adding this new method should be helpful.

Sql below will get all partitions from metastore, which put much burden on metastore;
```
CREATE TABLE `partition_test`(`col` int) PARTITIONED BY (`pt` byte)
SELECT * FROM partition_test WHERE CAST(pt AS INT)=1
```
The reason is that the the analyzed attribute `dt` is wrapped in `Cast` and `HiveShim` fails to generate a proper partition filter.
This pr proposes to take `Cast` into consideration when generate partition filter.

Although [SPARK-22654](https://issues.apache.org/jira/browse/SPARK-22654) made `HiveExternalCatalogVersionsSuite` download from Apache mirrors three times, it has been flaky because it didn't verify the downloaded file. Some Apache mirrors terminate the downloading abnormally, the *corrupted* file shows the following errors.
```

```
This has been reported weirdly in two ways. For example, the above case is reported as Case 2 `no failures`.
- Case 1. [Test Result (1 failure / +1)](https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-master-test-sbt-hadoop-2.7/4389/)

This PR aims to make `HiveExternalCatalogVersionsSuite` more robust by verifying the downloaded `tgz` file by extracting and checking the existence of `bin/spark-submit`. If it turns out that the file is empty or corrupted, `HiveExternalCatalogVersionsSuite` will do retry logic like the download failure.

In this case, the partition pruning happens before the planning phase of scalar subquery expressions.
For scalar subquery expressions, the planning occurs late in the cycle (after the physical planning) in "PlanSubqueries" just before execution. Currently we try to execute the scalar subquery expression as part of partition pruning and fail as it implements Unevaluable.
The fix attempts to ignore the Subquery expressions from partition pruning computation. Another option can be to somehow plan the subqueries before the partition pruning. Since this may not be a commonly occuring expression, i am opting for a simpler fix.

## What changes were proposed in this pull request?
This pr fixed code so that `cache` could prevent any jobs from being triggered.
For example, in the current master, an operation below triggers a actual job;
```
val df = spark.range(10000000000L)
.filter('id > 1000)
.orderBy('id.desc)
.cache()
```
This triggers a job while the cache should be lazy. The problem is that, when creating `InMemoryRelation`, we build the RDD, which calls `SparkPlan.execute` and may trigger jobs, like sampling job for range partitioner, or broadcast job.
This pr removed the code to build a cached `RDD` in the constructor of `InMemoryRelation` and added `CachedRDDBuilder` to lazily build the `RDD` in `InMemoryRelation`. Then, the first call of `CachedRDDBuilder.cachedColumnBuffers` triggers a job to materialize the cache in `InMemoryTableScanExec` .

## What changes were proposed in this pull request?
This updates the OptimizeMetadataOnlyQuery rule to use filter expressions when listing partitions, if there are filter nodes in the logical plan. This avoids listing all partitions for large tables on the driver.
This also fixes a minor bug where the partitions returned from fsRelation cannot be serialized without hitting a stack level too deep error. This is caused by serializing a stream to executors, where the stream is a recursive structure. If the stream is too long, the serialization stack reaches the maximum level of depth. The fix is to create a LocalRelation using an Array instead of the incoming Seq.

In current code, it will scanning all partition paths when spark.sql.hive.verifyPartitionPath=true.
e.g. table like below:
```
CREATE TABLE `test`(
`id` int,
`age` int,
`name` string)
PARTITIONED BY (
`A` string,
`B` string)
load data local inpath '/tmp/data0' into table test partition(A='00', B='00')
load data local inpath '/tmp/data1' into table test partition(A='01', B='01')
load data local inpath '/tmp/data2' into table test partition(A='10', B='10')
load data local inpath '/tmp/data3' into table test partition(A='11', B='11')
```
If I query with SQL – "select * from test where A='00' and B='01' ", current code will scan all partition paths including '/data/A=00/B=00', '/data/A=00/B=00', '/data/A=01/B=01', '/data/A=10/B=10', '/data/A=11/B=11'. It costs much time and memory cost.
This pr proposes to avoid iterating all partition paths. Add a config `spark.files.ignoreMissingFiles` and ignore the `file not found` when `getPartitions/compute`(for hive table scan). This is much like the logic brought by
`spark.sql.files.ignoreMissingFiles`(which is for datasource scan).

TableReader would get disproportionately slower as the number of columns in the query increased.

## What changes were proposed in this pull request?
Currently `PartitioningAwareFileIndex` accepts an optional parameter `userPartitionSchema`. If provided, it will combine the inferred partition schema with the parameter.
However,
1. to get `userPartitionSchema`, we need to combine inferred partition schema with `userSpecifiedSchema`
2. to get the inferred partition schema, we have to create a temporary file index.
Only after that, a final version of `PartitioningAwareFileIndex` can be created.
This can be improved by passing `userSpecifiedSchema` to `PartitioningAwareFileIndex`.
With the improvement, we can reduce redundant code and avoid parsing the file partition twice.

Currently, the active spark session is set inconsistently (e.g., in createDataFrame, prior to query execution). Many places in spark also incorrectly query active session when they should be calling activeSession.getOrElse(defaultSession) and so might get None even if a Spark session exists.
The semantics here can be cleaned up if we also set the active session when the default session is set.

isSharedClass returns if some classes can/should be shared or not. It checks if the classes names have some keywords or start with some names. Following the logic, it can occur unintended behaviors when a custom package has `slf4j` inside the package or class name. As I guess, the first intention seems to figure out the class containing `org.slf4j`. It would be better to change the comparison logic to `name.startsWith("org.slf4j")`

This patch should pass all of the current tests and keep all of the current behaviors. In my case, I'm using ProtobufDeserializer to get a table schema from hive tables. Thus some Protobuf packages and names have `slf4j` inside. Without this patch, it cannot be resolved because of ClassCastException from different classloaders.

A few places in `spark-sql` were using `sc.hadoopConfiguration` directly. They should be using `sessionState.newHadoopConf()` to blend in configs that were set through `SQLConf`.
Also, for better UX, for these configs blended in from `SQLConf`, we should consider removing the `spark.hadoop` prefix, so that the settings are recognized whether or not they were specified by the user.

Tested that AlterTableRecoverPartitions now correctly recognizes settings that are passed in to the FileSystem through SQLConf.

## What changes were proposed in this pull request?
Refactor ColumnStat to be more flexible.
* Split `ColumnStat` and `CatalogColumnStat` just like `CatalogStatistics` is split from `Statistics`. This detaches how the statistics are stored from how they are processed in the query plan. `CatalogColumnStat` keeps `min` and `max` as `String`, making it not depend on dataType information.
* For `CatalogColumnStat`, parse column names from property names in the metastore (`KEY_VERSION` property), not from metastore schema. This means that `CatalogColumnStat`s can be created for columns even if the schema itself is not stored in the metastore.
* Make all fields optional. `min`, `max` and `histogram` for columns were optional already. Having them all optional is more consistent, and gives flexibility to e.g. drop some of the fields through transformations if they are difficult / impossible to calculate.
The added flexibility will make it possible to have alternative implementations for stats, and separates stats collection from stats and estimation processing in plans.
## How was this patch tested?
Refactored existing tests to work with refactored `ColumnStat` and `CatalogColumnStat`.
New tests added in `StatisticsSuite` checking that backwards / forwards compatibility is not broken.

## What changes were proposed in this pull request?
This is a regression in Spark 2.3.
In Spark 2.2, we have a fragile UI support for SQL data writing commands. We only track the input query plan of `FileFormatWriter` and display its metrics. This is not ideal because we don't know who triggered the writing(can be table insertion, CTAS, etc.), but it's still useful to see the metrics of the input query.
In Spark 2.3, we introduced a new mechanism: `DataWritigCommand`, to fix the UI issue entirely. Now these writing commands have real children, and we don't need to hack into the `FileFormatWriter` for the UI. This also helps with `explain`, now `explain` can show the physical plan of the input query, while in 2.2 the physical writing plan is simply `ExecutedCommandExec` and it has no child.
However there is a regression in CTAS. CTAS commands don't extend `DataWritigCommand`, and we don't have the UI hack in `FileFormatWriter` anymore, so the UI for CTAS is just an empty node. See https://issues.apache.org/jira/browse/SPARK-22977 for more information about this UI issue.
To fix it, we should apply the `DataWritigCommand` mechanism to CTAS commands.
TODO: In the future, we should refactor this part and create some physical layer code pieces for data writing, and reuse them in different writing commands. We should have different logical nodes for different operators, even some of them share some same logic, e.g. CTAS, CREATE TABLE, INSERT TABLE. Internally we can share the same physical logic.

The two configs are not in the default `ObjectStore` properties, so any run hive commands after these two lines will set the `propsChanged` flag in the `ObjectStore.setConf` and then cause thread leaks.
I don't think the two lines are very useful. They can be removed safely.

## What changes were proposed in this pull request?
This PR proposes modifying the match statement that gets the columns of a row in HiveThriftServer. There was previously no case for `UserDefinedType`, so querying a table that contained them would throw a match error. The changes catch that case and return the string representation.
## How was this patch tested?
While I would have liked to add a unit test, I couldn't easily incorporate UDTs into the ``HiveThriftServer2Suites`` pipeline. With some guidance I would be happy to push a commit with tests.
Instead I did a manual test by loading a `DataFrame` with Point UDT in a spark shell with a HiveThriftServer. Then in beeline, connecting to the server and querying that table.
Here is the result before the change
```
0: jdbc:hive2://localhost:10000> select * from chicago;
Error: scala.MatchError: org.apache.spark.sql.PointUDT2d980dc3 (of class org.apache.spark.sql.PointUDT) (state=,code=0)
```
And after the change:
```
0: jdbc:hive2://localhost:10000> select * from chicago;

## What changes were proposed in this pull request?
hive tests have been failing when they are run locally (Mac Os) after a recent change in the trunk. After running the tests for some time, the test fails with OOM with Error: unable to create new native thread.
I noticed the thread count goes all the way up to 2000+ after which we start getting these OOM errors. Most of the threads seem to be related to the connection pool in hive metastore (BoneCP-xxxxx-xxxx ). This behaviour change is happening after we made the following change to HiveClientImpl.reset()
``` SQL
def reset(): Unit = withHiveState {
try {
// code
} finally {
runSqlHive("USE default") ===> this is causing the issue
}
```
I am proposing to temporarily back-out part of a fix made to address SPARK-23000 to resolve this issue while we work-out the exact reason for this sudden increase in thread counts.
## How was this patch tested?
Ran hive/test multiple times in different machines.

## What changes were proposed in this pull request?
It is a common pattern to apply multiple transforms to a `Dataset` (using `Dataset.withColumn` for example. This is currently quite expensive because we run `CheckAnalysis` on the full plan and create an encoder for each intermediate `Dataset`.
This PR extends the usage of the `AnalysisBarrier` to include `CheckAnalysis`. By doing this we hide the already analyzed plan from `CheckAnalysis` because barrier is a `LeafNode`. The `AnalysisBarrier` is in the `FinishAnalysis` phase of the optimizer.
We also make binding the `Dataset` encoder lazy. The bound encoder is only needed when we materialize the dataset.
## How was this patch tested?
Existing test should cover this.

**Proposal**
Add a per-query ID to the codegen stages as represented by `WholeStageCodegenExec` operators. This ID will be used in
- the explain output of the physical plan, and in
- the generated class name.
Specifically, this ID will be stable within a query, counting up from 1 in depth-first post-order for all the `WholeStageCodegenExec` inserted into a plan.
The ID value 0 is reserved for "free-floating" `WholeStageCodegenExec` objects, which may have been created for one-off purposes, e.g. for fallback handling of codegen stages that failed to codegen the whole stage and wishes to codegen a subset of the children operators (as seen in `org.apache.spark.sql.execution.FileSourceScanExec#doExecute`).
Example: for the following query:
```scala
scala> spark.conf.set("spark.sql.autoBroadcastJoinThreshold", 1)
scala> val df1 = spark.range(10).select('id as 'x, 'id + 1 as 'y).orderBy('x).select('x + 1 as 'z, 'y)
df1: org.apache.spark.sql.DataFrame = [z: bigint, y: bigint]
scala> val df2 = spark.range(5)
df2: org.apache.spark.sql.Dataset[Long] = [id: bigint]
scala> val query = df1.join(df2, 'z === 'id)
query: org.apache.spark.sql.DataFrame = [z: bigint, y: bigint ... 1 more field]
```
The explain output before the change is:
```scala
scala> query.explain
== Physical Plan ==
*SortMergeJoin [z#9L], [id#13L], Inner
:- *Sort [z#9L ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(z#9L, 200)
: +- *Project [(x#3L + 1) AS z#9L, y#4L]
: +- *Sort [x#3L ASC NULLS FIRST], true, 0
: +- Exchange rangepartitioning(x#3L ASC NULLS FIRST, 200)
: +- *Project [id#0L AS x#3L, (id#0L + 1) AS y#4L]
: +- *Range (0, 10, step=1, splits=8)
+- *Sort [id#13L ASC NULLS FIRST], false, 0
+- Exchange hashpartitioning(id#13L, 200)
+- *Range (0, 5, step=1, splits=8)
```
Note how codegen'd operators are annotated with a prefix `"*"`. See how the `SortMergeJoin` operator and its direct children `Sort` operators are adjacent and all annotated with the `"*"`, so it's hard to tell they're actually in separate codegen stages.
and after this change it'll be:
```scala
scala> query.explain
== Physical Plan ==
*(6) SortMergeJoin [z#9L], [id#13L], Inner
:- *(3) Sort [z#9L ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(z#9L, 200)
: +- *(2) Project [(x#3L + 1) AS z#9L, y#4L]
: +- *(2) Sort [x#3L ASC NULLS FIRST], true, 0
: +- Exchange rangepartitioning(x#3L ASC NULLS FIRST, 200)
: +- *(1) Project [id#0L AS x#3L, (id#0L + 1) AS y#4L]
: +- *(1) Range (0, 10, step=1, splits=8)
+- *(5) Sort [id#13L ASC NULLS FIRST], false, 0
+- Exchange hashpartitioning(id#13L, 200)
+- *(4) Range (0, 5, step=1, splits=8)
```
Note that the annotated prefix becomes `"*(id) "`. See how the `SortMergeJoin` operator and its direct children `Sort` operators have different codegen stage IDs.
It'll also show up in the name of the generated class, as a suffix in the format of `GeneratedClass$GeneratedIterator$id`.
For example, note how `GeneratedClass$GeneratedIteratorForCodegenStage3` and `GeneratedClass$GeneratedIteratorForCodegenStage6` in the following stack trace corresponds to the IDs shown in the explain output above:

**Rationale**
Right now, the codegen from Spark SQL lacks the means to differentiate between a couple of things:
1. It's hard to tell which physical operators are in the same WholeStageCodegen stage. Note that this "stage" is a separate notion from Spark's RDD execution stages; this one is only to delineate codegen units.
There can be adjacent physical operators that are both codegen'd but are in separate codegen stages. Some of this is due to hacky implementation details, such as the case with `SortMergeJoin` and its `Sort` inputs -- they're hard coded to be split into separate stages although both are codegen'd.
When printing out the explain output of the physical plan, you'd only see the codegen'd physical operators annotated with a preceding star (`'*'`) but would have no way to figure out if they're in the same stage.
2. Performance/error diagnosis
The generated code has class/method names that are hard to differentiate between queries or even between codegen stages within the same query. If we use a Java-level profiler to collect profiles, or if we encounter a Java-level exception with a stack trace in it, it's really hard to tell which part of a query it's at.
By introducing a per-query codegen stage ID, we'd at least be able to know which codegen stage (and in turn, which group of physical operators) was a profile tick or an exception happened.
The reason why this proposal uses a per-query ID is because it's stable within a query, so that multiple runs of the same query will see the same resulting IDs. This both benefits understandability for users, and also it plays well with the codegen cache in Spark SQL which uses the generated source code as the key.
The downside to using per-query IDs as opposed to a per-session or globally incrementing ID is of course we can't tell apart different query runs with this ID alone. But for now I believe this is a good enough tradeoff.
## How was this patch tested?
Existing tests. This PR does not involve any runtime behavior changes other than some name changes.
The SQL query test suites that compares explain outputs have been updates to ignore the newly added `codegenStageId`.

Closes#20224 from rednaxelafx/wsc-codegenstageid.
Because the call to the constructor of HiveClientImpl crosses class loader
boundaries, different versions of the same class (Configuration in this
case) were loaded, and that caused a runtime error when instantiating the
client. By using a safer type in the signature of the constructor, it's
possible to avoid the problem.
I considered removing 'sharesHadoopClasses', but it may still be desired
(even though there are 0 users of it since it was not working). When Spark
starts to support Hadoop 3, it may be necessary to use that option to
load clients for older Hive metastore versions that don't know about
Hadoop 3.
Tested with added unit test.
