### What changes were proposed in this pull request?
Increase the number of calls to Hive external catalog in the test for `ALTER TABLE .. ADD PARTITION`.
### Why are the changes needed?
There is a logical conflict between https://github.com/apache/spark/pull/31101 and https://github.com/apache/spark/pull/31092. The first one fixes a caching issue and increases the number of calls to Hive external catalog.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
By running the modified test:
```

### What changes were proposed in this pull request?
Use `initialize(StructObjectInspector argOIs)` instead `initialize(ObjectInspector[] args)` in `HiveGenericUDTF`.
### Why are the changes needed?
In our case, we implement a Hive `GenericUDTF` and override `initialize(StructObjectInspector argOIs)`. Then it's ok to execute with Hive, but failed with Spark SQL. Here is the Spark SQL error msg:
```
No handler for UDF/UDAF/UDTF 'com.xxxx.xxxUDTF': java.lang.IllegalStateException:
Should not be called directly Please make sure your function overrides
`public StructObjectInspector initialize(ObjectInspector[] args)`.
```
The reason is Spark `HiveGenericUDTF` call `initialize(ObjectInspector[] argOIs)` to init a UDTF, but it's a Deprecated method.
```
public StructObjectInspector initialize(StructObjectInspector argOIs) throws UDFArgumentException {
List<? extends StructField> inputFields = argOIs.getAllStructFieldRefs();
ObjectInspector[] udtfInputOIs = new ObjectInspector[inputFields.size()];
for(int i = 0; i < inputFields.size(); ++i) {
udtfInputOIs[i] = ((StructField)inputFields.get(i)).getFieldObjectInspector();
}
return this.initialize(udtfInputOIs);
}
Deprecated
public StructObjectInspector initialize(ObjectInspector[] argOIs) throws UDFArgumentException {
throw new IllegalStateException("Should not be called directly");
}
```
We should use `initialize(StructObjectInspector argOIs)` to do this so that we can be compatible both of the two method. Same as Hive.
### Does this PR introduce _any_ user-facing change?
Yes, fix UDTF initialize method.
### How was this patch tested?

Signed-off-by: Dongjoon Hyun <dhyun@apple.com>
### What changes were proposed in this pull request?
1. Recognize `null` while parsing partition specs, and put `null` instead of `"null"` as partition values.
2. For V1 catalog: replace `null` by `__HIVE_DEFAULT_PARTITION__`.
3. For V2 catalogs: pass `null` AS IS, and let catalog implementations to decide how to handle `null`s as partition values in spec.
### Why are the changes needed?
Currently, `null` in partition specs is recognized as the `"null"` string which could lead to incorrect results, for example:
```sql
spark-sql> CREATE TABLE tbl5 (col1 INT, p1 STRING) USING PARQUET PARTITIONED BY (p1);
spark-sql> INSERT INTO TABLE tbl5 PARTITION (p1 = null) SELECT 0;
spark-sql> SELECT isnull(p1) FROM tbl5;
false
```
Even we inserted a row to the partition with the `null` value, **the resulted table doesn't contain `null`**.
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above works as expected:
```sql
spark-sql> SELECT isnull(p1) FROM tbl5;
true
```
### How was this patch tested?
1. By running the affected test suites `SQLQuerySuite`, `AlterTablePartitionV2SQLSuite` and `v1/ShowPartitionsSuite`.
2. Compiling by Scala 2.13:
```
$ ./dev/change-scala-version.sh 2.13

After hive-2.3 we will set COLUMN_NAME_DELIMITER to special char when col name cntains ','：
6f4c35c9e9/metastore/src/java/org/apache/hadoop/hive/metastore/MetaStoreUtils.java (L1180-L1188)6f4c35c9e9/metastore/src/java/org/apache/hadoop/hive/metastore/MetaStoreUtils.java (L1044-L1075)
And in script transform, we parse column name to avoid this problem
554600c2af/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/HiveScriptTransformationExec.scala (L257-L261)
So I think in `InsertIntoHiveDirComman`, we should do same thing too. And I have verified this method can make spark-2.4 work well.

### What changes were proposed in this pull request?
In the `saveAsTable()` and `insertInto()` methods of `DataFrameWriter`, recognize `spark_catalog` as the default session catalog in table names.
### Why are the changes needed?
1. To simplify writing of unified v1 and v2 tests
2. To improve Spark SQL user experience. `insertInto()` should have feature parity with the `INSERT INTO` sql command. Currently, `insertInto()` fails on a table from a namespace in `spark_catalog`:
```scala
scala> sql("CREATE NAMESPACE spark_catalog.ns")
scala> Seq(0).toDF().write.saveAsTable("spark_catalog.ns.tbl")
org.apache.spark.sql.AnalysisException: Couldn't find a catalog to handle the identifier spark_catalog.ns.tbl.
at org.apache.spark.sql.DataFrameWriter.saveAsTable(DataFrameWriter.scala:629)
... 47 elided
scala> Seq(0).toDF().write.insertInto("spark_catalog.ns.tbl")
org.apache.spark.sql.AnalysisException: Couldn't find a catalog to handle the identifier spark_catalog.ns.tbl.
at org.apache.spark.sql.DataFrameWriter.insertInto(DataFrameWriter.scala:498)
... 47 elided
```
but `INSERT INTO` succeed:
```sql
spark-sql> create table spark_catalog.ns.tbl (c int);
spark-sql> insert into spark_catalog.ns.tbl select 0;
spark-sql> select * from spark_catalog.ns.tbl;
0
```
### Does this PR introduce _any_ user-facing change?
Yes. After the changes for the example above:
```scala
scala> Seq(0).toDF().write.saveAsTable("spark_catalog.ns.tbl")
scala> Seq(1).toDF().write.insertInto("spark_catalog.ns.tbl")
scala> spark.table("spark_catalog.ns.tbl").show(false)

Some tests that are fixed in https://github.com/apache/spark/pull/30655 doesn't really require AQE off. Instead, they could use `AdaptiveSparkPlanHelper` to pass when AQE on. It's better to run tests with AQE on since we've turned it on by default.

### What changes were proposed in this pull request?
Throw `PartitionAlreadyExistsException` from `ALTER TABLE .. RENAME TO PARTITION` for a table from Hive V1 External Catalog in the case when the target partition already exists.
### Why are the changes needed?
1. To have the same behavior of V1 In-Memory and Hive External Catalog.
2. To not propagate internal Hive's exceptions to users.
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the partition renaming command throws `PartitionAlreadyExistsException` for tables from the Hive catalog.
### How was this patch tested?
Added new UT:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *HiveCatalogedDDLSuite"
```

### What changes were proposed in this pull request?
1. Move the `DROP TABLE` parsing tests to `DropTableParserSuite`
2. Place the v1 tests for `DROP TABLE` from `DDLSuite` and v2 tests from `DataSourceV2SQLSuite` to the common trait `DropTableSuiteBase`, so, the tests will run for V1, Hive V1 and V2 DS.
### Why are the changes needed?
- The unification will allow to run common `DROP TABLE` tests for both DSv1 and Hive DSv1, DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
By running new test suites:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *DropTableParserSuite"

### What changes were proposed in this pull request?
This PR proposes to migrate `ALTER TABLE ... RENAME TO PARTITION` to use `UnresolvedTable` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
Note that `ALTER TABLE ... RENAME TO PARTITION` is not supported for v2 tables.
### Why are the changes needed?
The PR makes the resolution consistent behavior consistent. For example,
```
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint, val string) USING csv PARTITIONED BY (id)")
sql("CREATE TEMPORARY VIEW t AS SELECT 2")
sql("USE spark_catalog.test")
sql("ALTER TABLE t PARTITION (id=1) RENAME TO PARTITION (id=2)") // works fine assuming id=1 exists.
```
, but after this PR:
```
sql("ALTER TABLE t PARTITION (id=1) RENAME TO PARTITION (id=2)")
org.apache.spark.sql.AnalysisException: t is a temp view. 'ALTER TABLE ... RENAME TO PARTITION' expects a table; line 1 pos 0
```
, which is the consistent behavior with other commands.
### Does this PR introduce _any_ user-facing change?
After this PR, `ALTER TABLE` in the above example is resolved to a temp view `t` first instead of `spark_catalog.test.t`.
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
`HiveDDLSuite` has many of the following patterns:
```scala
val e = intercept[AnalysisException] {
sql(sqlString)
}
assert(e.message.contains(exceptionMessage))
```
However, there already exists `assertAnalysisError` helper function which does exactly the same thing.

No, just refactoring the test code.

### What changes were proposed in this pull request?
As https://github.com/apache/spark/pull/29893#discussion_r545303780 mentioned:
> We need to set spark.conf.set("hive.exec.dynamic.partition.mode", "nonstrict") before executing this suite; otherwise, test("insert with column list - follow table output order + partitioned table") will fail.
The reason why it does not fail because some test cases [running before this suite] do not change the default value of hive.exec.dynamic.partition.mode back to strict. However, the order of test suite execution is not deterministic.

avoid flakiness in tests

### What changes were proposed in this pull request?
Hive metastore has a limitation for the table property length. To work around it, Spark split the schema json string into several parts when saving to hive metastore as table properties. We need to do the same for histogram column stats as it can go very big.
This PR refactors the table property splitting code, so that we can share it between the schema json string and histogram column stats.

To be able to analyze table when histogram data is big.

### What changes were proposed in this pull request?
Based on the discussion https://github.com/apache/spark/pull/30743#discussion_r543124594, this PR proposes to remove the command name in AnalysisException message when a relation is not resolved.
For some of the commands that use `UnresolvedTable`, `UnresolvedView`, and `UnresolvedTableOrView` to resolve an identifier, when the identifier cannot be resolved, the exception will be something like `Table or view not found for 'SHOW TBLPROPERTIES': badtable`. The command name (`SHOW TBLPROPERTIES` in this case) should be dropped to be consistent with other existing commands.
### Why are the changes needed?
To make the exception message consistent.
### Does this PR introduce _any_ user-facing change?
Yes, the exception message will be changed from
```
Table or view not found for 'SHOW TBLPROPERTIES': badtable
```
to
```
Table or view not found: badtable
```
for commands that use `UnresolvedTable`, `UnresolvedView`, and `UnresolvedTableOrView` to resolve an identifier.

### What changes were proposed in this pull request?
[SPARK-33546] stated the there are three inconsistency behaviors for CREATE TABLE LIKE.
1. CREATE TABLE LIKE does not validate the user-specified hive serde. e.g., STORED AS PARQUET can't be used with ROW FORMAT SERDE.
2. CREATE TABLE LIKE requires STORED AS and ROW FORMAT SERDE to be specified together, which is not necessary.
3. CREATE TABLE LIKE does not respect the default hive serde.
This PR fix No.1, and after investigate, No.2 and No.3 turn out not to be issue.
Within Hive.
CREATE TABLE abc ... ROW FORMAT SERDE 'xxx.xxx.SerdeClass' (Without Stored as) will have
following result. Using the user specific SerdeClass and fetch default input/output format from default textfile format.
```
SerDe Library: xxx.xxx.SerdeClass
InputFormat: org.apache.hadoop.mapred.TextInputFormat
OutputFormat: org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat
```
But for
CREATE TABLE dst LIKE src ROW FORMAT SERDE 'xxx.xxx.SerdeClass' (Without Stored as) will just ignore user specific SerdeClass and using (input, output, serdeClass) from src table.
It's better to just throw an exception on such ambiguous behavior, so No.2 is not an issue, but in the PR, we add some comments.
For No.3, in fact, CreateTableLikeCommand is using following logical to try to follow src table's storageFormat if current fileFormat.inputFormat is empty
```
val newStorage = if (fileFormat.inputFormat.isDefined) {
fileFormat
} else {
sourceTableDesc.storage.copy(locationUri = fileFormat.locationUri)
}
```
If we try to fill the new target table with HiveSerDe.getDefaultStorage if file format and row format is not explicity spefified, it will break the CREATE TABLE LIKE semantic.

### What changes were proposed in this pull request?
Modify the tests that add partitions with `LOCATION`, and where the number of nested folders in `LOCATION` doesn't match to the number of partitioned columns. In that case, `ALTER TABLE .. DROP PARTITION` tries to access (delete) folder out of the "base" path in `LOCATION`.
The problem belongs to Hive's MetaStore method `drop_partition_common`:
8696c82d07/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java (L4876)
which tries to delete empty partition sub-folders recursively starting from the most deeper partition sub-folder up to the base folder. In the case when the number of sub-folder is not equal to the number of partitioned columns `part_vals.size()`, the method will try to list and delete folders out of the base path.
### Why are the changes needed?

The issue can be reproduced by the following steps:
1. Create a base folder, for example: `/Users/maximgekk/tmp/part-location`
2. Create a sub-folder in the base folder and drop permissions for it:
```
$ mkdir /Users/maximgekk/tmp/part-location/aaa
$ chmod a-rwx chmod a-rwx /Users/maximgekk/tmp/part-location/aaa
$ ls -al /Users/maximgekk/tmp/part-location
total 0
drwxr-xr-x 3 maximgekk staff 96 Dec 13 18:42 .
drwxr-xr-x 33 maximgekk staff 1056 Dec 13 18:32 ..
d--------- 2 maximgekk staff 64 Dec 13 18:42 aaa
```
3. Create a table with a partition folder in the base folder:
```sql
spark-sql> create table tbl (id int) partitioned by (part0 int, part1 int);
spark-sql> alter table tbl add partition (part0=1,part1=2) location '/Users/maximgekk/tmp/part-location/tbl';
```
4. Try to drop this partition:
```
spark-sql> alter table tbl drop partition (part0=1,part1=2);
20/12/13 18:46:07 ERROR HiveClientImpl:
======================
Attempt to drop the partition specs in table 'tbl' database 'default':
Map(part0 -> 1, part1 -> 2)
In this attempt, the following partitions have been dropped successfully:
The remaining partitions have not been dropped:
[1, 2]
======================
Error in query: org.apache.hadoop.hive.ql.metadata.HiveException: Error accessing file:/Users/maximgekk/tmp/part-location/aaa;
org.apache.spark.sql.AnalysisException: org.apache.hadoop.hive.ql.metadata.HiveException: Error accessing file:/Users/maximgekk/tmp/part-location/aaa;
```
The command fails because it tries to access to the sub-folder `aaa` that is out of the partition path `/Users/maximgekk/tmp/part-location/tbl`.

### What changes were proposed in this pull request?
Throw `PartitionsAlreadyExistException` from `createPartitions()` in Hive external catalog when a partition exists. Currently, `HiveExternalCatalog.createPartitions()` throws `AlreadyExistsException` wrapped by `AnalysisException`.
In the PR, I propose to catch `AlreadyExistsException` in `HiveClientImpl` and replace it by `PartitionsAlreadyExistException`.
### Why are the changes needed?
The behaviour of Hive external catalog deviates from V1/V2 in-memory catalogs that throw `PartitionsAlreadyExistException`. To improve user experience with Spark SQL, it would be better to throw the same exception.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
This PR adds `allowTemp` flag to `UnresolvedView` so that `Analyzer` can check whether to resolve temp views or not.
This PR also migrates `ALTER VIEW ... SET/UNSET TBLPROPERTIES` to use `UnresolvedView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
### Why are the changes needed?
To use `UnresolvedView` for view resolution.
One benefit is that the exception message is better for `ALTER VIEW ... SET/UNSET TBLPROPERTIES`. Before, if a temp view is passed, you will just get `NoSuchTableException` with `Table or view 'tmpView' not found in database 'default'`. But with this PR, you will get more description exception message: `tmpView is a temp view. ALTER VIEW ... SET TBLPROPERTIES expects a permanent view`.
### Does this PR introduce _any_ user-facing change?
The exception message changes as describe above.
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
1. Move the `ALTER TABLE .. ADD PARTITION` parsing tests to `AlterTableAddPartitionParserSuite`
2. Place v1 tests for `ALTER TABLE .. ADD PARTITION` from `DDLSuite` and v2 tests from `AlterTablePartitionV2SQLSuite` to the common trait `AlterTableAddPartitionSuiteBase`, so, the tests will run for V1, Hive V1 and V2 DS.
### Why are the changes needed?
- The unification will allow to run common `ALTER TABLE .. ADD PARTITION` tests for both DSv1 and Hive DSv1, DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.

### What changes were proposed in this pull request?
For CRETE TABLE [AS SELECT] command, creates native Parquet table if neither USING nor STORE AS is specified and `spark.sql.legacy.createHiveTableByDefault` is false.
This is a retry after we unify the CREATE TABLE syntax. It partially reverts d2bec5e265
This PR allows `CREATE EXTERNAL TABLE` when `LOCATION` is present. This was not allowed for data source tables before, which is an unnecessary behavior different with hive tables.
### Why are the changes needed?
Changing from Hive text table to native Parquet table has many benefits:
1. be consistent with `DataFrameWriter.saveAsTable`.
2. better performance
3. better support for nested types (Hive text table doesn't work well with nested types, e.g. `insert into t values struct(null)` actually inserts a null value not `struct(null)` if `t` is a Hive text table, which leads to wrong result)
4. better interoperability as Parquet is a more popular open file format.
### Does this PR introduce _any_ user-facing change?
No by default. If the config is set, the behavior change is described below:
Behavior-wise, the change is very small as the native Parquet table is also Hive-compatible. All the Spark DDL commands that works for hive tables also works for native Parquet tables, with two exceptions: `ALTER TABLE SET [SERDE | SERDEPROPERTIES]` and `LOAD DATA`.
char/varchar behavior has been taken care by https://github.com/apache/spark/pull/30412, and there is no behavior difference between data source and hive tables.
One potential issue is `CREATE TABLE ... LOCATION ...` while users want to directly access the files later. It's more like a corner case and the legacy config should be good enough.
Another potential issue is users may use Spark to create the table and then use Hive to add partitions with different serde. This is not allowed for Spark native tables.
### How was this patch tested?
Re-enable the tests

### What changes were proposed in this pull request?
This PR adds the char/varchar type which is kind of a variant of string type:
1. Char type is fixed-length string. When comparing char type values, we need to pad the shorter one to the longer length.
2. Varchar type is string with a length limitation.
To implement the char/varchar semantic, this PR:
1. Do string length check when writing to char/varchar type columns.
2. Do string padding when reading char type columns. We don't do it at the writing side to save storage space.
3. Do string padding when comparing char type column with string literal or another char type column. (string literal is fixed length so should be treated as char type as well)
To simplify the implementation, this PR doesn't propagate char/varchar type info through functions/operators(e.g. `substring`). That said, a column can only be char/varchar type if it's a table column, not a derived column like `SELECT substring(col)`.
To be safe, this PR doesn't add char/varchar type to the query engine(expression input check, internal row framework, codegen framework, etc.). We will replace char/varchar type by string type with metadata (`Attribute.metadata` or `StructField.metadata`) that includes the original type string before it goes into the query engine. That said, the existing code will not see char/varchar type but only string type.
char/varchar type may come from several places:
1. v1 table from hive catalog.
2. v2 table from v2 catalog.
3. user-specified schema in `spark.read.schema` and `spark.readStream.schema`
4. `Column.cast`
5. schema string in places like `from_json`, pandas UDF, etc. These places use SQL parser which replaces char/varchar with string already, even before this PR.
This PR covers all the above cases, implements the length check and padding feature by looking at string type with special metadata.
### Why are the changes needed?
char and varchar are standard SQL types. varchar is widely used in other databases instead of string type.
### Does this PR introduce _any_ user-facing change?
For hive tables: now the table insertion fails if the value exceeds char/varchar length. Previously we truncate the value silently.
For other tables:
1. now char type is allowed.
2. now we have length check when inserting to varchar columns. Previously we write the value as it is.

### What changes were proposed in this pull request?
This PR proposes to support `CHACHE/UNCACHE TABLE` commands for v2 tables.
In addtion, this PR proposes to migrate `CACHE/UNCACHE TABLE` to use `UnresolvedTableOrView` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
### Why are the changes needed?
To support `CACHE/UNCACHE TABLE` commands for v2 tables.
Note that `CACHE/UNCACHE TABLE` for v1 tables/views go through `SparkSession.table` to resolve identifier, which resolves temp views first, so there is no change in the behavior by moving to the new framework.
### Does this PR introduce _any_ user-facing change?
Yes. Now the user can run `CACHE/UNCACHE TABLE` commands on v2 tables.
### How was this patch tested?

#### JIRA expectations
```
INSERT currently does not support named column lists.
INSERT INTO <table> (col1, col2,…) VALUES( 'val1', 'val2', … )
Note, we assume the column list contains all the column names. Issue an exception if the list is not complete. The column order could be different from the column order defined in the table definition.
```
#### implemetations
In this PR, we add a column list as an optional part to the `INSERT OVERWRITE/INTO` statements:
```
/**
* {{{
* INSERT OVERWRITE TABLE tableIdentifier [partitionSpec [IF NOT EXISTS]]? [identifierList] ...
* INSERT INTO [TABLE] tableIdentifier [partitionSpec] [identifierList] ...
* }}}

The column list represents all expected columns with an explicit order that you want to insert to the target table. **Particularly**, we assume the column list contains all the column names in the current implementation, it will fail when the list is incomplete.
In **Analyzer**, we add a code path to resolve the column list in the `ResolveOutputRelation` rule before it is transformed to v1 or v2 command. It will fail here if the list has any field that not belongs to the target table.
Then, for v2 command, e.g. `AppendData`, we use the resolved column list and output of the target table to resolve the output of the source query `ResolveOutputRelation` rule. If the list has duplicated columns, we fail. If the list is not empty but the list size does not match the target table, we fail. If no other exceptions occur, we use the column list to map the output of the source query to the output of the target table. The column list will be set to Nil and it will not hit the rule again after it is resolved.
for v1 command, those all happen in the `PreprocessTableInsertion` rule

### What changes were proposed in this pull request?
This PR proposes to improve the exception messages while `UnresolvedTableOrView` is handled based on this suggestion: https://github.com/apache/spark/pull/30321#discussion_r521127001.
Currently, when an identifier is resolved to a temp view when a table/permanent view is expected, the following exception message is displayed (e.g., for `SHOW CREATE TABLE`):
```
t is a temp view not table or permanent view.
```
After this PR, the message will be:
```
t is a temp view. 'SHOW CREATE TABLE' expects a table or permanent view.
```
Also, if an identifier is not resolved, the following exception message is currently used:
```
Table or view not found: t
```
After this PR, the message will be:
```
Table or permanent view not found for 'SHOW CREATE TABLE': t
```
or
```
Table or view not found for 'ANALYZE TABLE ... FOR COLUMNS ...': t
```
### Why are the changes needed?
To improve the exception message.
### Does this PR introduce _any_ user-facing change?
Yes, the exception message will be changed as described above.

### What changes were proposed in this pull request?
* Unify the create table syntax in the parser by merging Hive and DataSource clauses
* Add `SerdeInfo` and `external` boolean to statement plans and update AstBuilder to produce them
* Add conversion from create statement plan to v1 create plans in ResolveSessionCatalog
* Support new statement clauses in ResolveCatalogs conversion to v2 create plans
* Remove SparkSqlParser rules for Hive syntax
* Add "option." namespace to distinguish SERDEPROPERTIES and OPTIONS in table properties
### Why are the changes needed?
* Current behavior is confusing.
* A way to pass the Hive create options to DSv2 is needed for a Hive source.
### Does this PR introduce any user-facing change?
Not by default, but v2 sources will be able to handle STORED AS and other Hive clauses.
### How was this patch tested?
Existing tests validate there are no behavior changes.
Update unit tests for using a statement plan for Hive create syntax:
* Move create tests from spark-sql DDLParserSuite into PlanResolutionSuite
* Add parser tests to spark-catalyst DDLParserSuite

### What changes were proposed in this pull request?
Remove SQL configuration spark.sql.legacy.allowCastNumericToTimestamp
### Why are the changes needed?
In the current master branch, there is a new configuration `spark.sql.legacy.allowCastNumericToTimestamp` which controls whether to cast Numeric types to Timestamp or not. The default value is true.
After https://github.com/apache/spark/pull/30260, the type conversion between Timestamp type and Numeric type is disallowed in ANSI mode. So, we don't need to a separate configuration `spark.sql.legacy.allowCastNumericToTimestamp` for disallowing the conversion. Users just need to set `spark.sql.ansi.enabled` for the behavior.
As the configuration is not in any released yet, we should remove the configuration to make things simpler.
### Does this PR introduce _any_ user-facing change?
No, since the configuration is not released yet.

### What changes were proposed in this pull request?
This PR aims the followings.
1. Upgrade from Scala 2.13.3 to 2.13.4 for Apache Spark 3.1
2. Fix exhaustivity issues in both Scala 2.12/2.13 (Scala 2.13.4 requires this for compilation.)
3. Enforce the improved exhaustive check by using the existing Scala 2.13 GitHub Action compilation job.
### Why are the changes needed?
Scala 2.13.4 is a maintenance release for 2.13 line and improves JDK 15 support.
- https://github.com/scala/scala/releases/tag/v2.13.4
Also, it improves exhaustivity check.
- https://github.com/scala/scala/pull/9140 (Check exhaustivity of pattern matches with "if" guards and custom extractors)
- https://github.com/scala/scala/pull/9147 (Check all bindings exhaustively, e.g. tuples components)
### Does this PR introduce _any_ user-facing change?
Yep. Although it's a maintenance version change, it's a Scala version change.
### How was this patch tested?
Pass the CIs and do the manual testing.
- Scala 2.12 CI jobs(GitHub Action/Jenkins UT/Jenkins K8s IT) to check the validity of code change.
- Scala 2.13 Compilation job to check the compilation

### What changes were proposed in this pull request?
We [rewrite](5197c5d2e7/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveShim.scala (L722-L724)) `In`/`InSet` predicate to `or` expressions when pruning Hive partitions. That will cause Hive metastore stack over flow if there are a lot of values.
This pr rewrite `InSet` predicate to `GreaterThanOrEqual` min value and `LessThanOrEqual ` max value when pruning Hive partitions to avoid Hive metastore stack overflow.
From our experience, `spark.sql.hive.metastorePartitionPruningInSetThreshold` should be less than 10000.

### What changes were proposed in this pull request?
This removes the `sharesHadoopClasses` flag from `IsolatedClientLoader` in Hive module.
### Why are the changes needed?
Currently, when initializing `IsolatedClientLoader`, users can set the `sharesHadoopClasses` flag to decide whether the `HiveClient` created should share Hadoop classes with Spark itself or not. In the latter case, the client will only load Hadoop classes from the Hive dependencies.
There are two reasons to remove this:
1. this feature is currently used in two cases: 1) unit tests, 2) when the Hadoop version defined in Maven can not be found when `spark.sql.hive.metastore.jars` is equal to "maven", which could be very rare.
2. when `sharesHadoopClasses` is false, Spark doesn't really only use Hadoop classes from Hive jars: we also download `hadoop-client` jar and put all the sub-module jars (e.g., `hadoop-common`, `hadoop-hdfs`) together with the Hive jars, and the Hadoop version used by `hadoop-client` is the same version used by Spark itself. As result, we're mixing two versions of Hadoop jars in the classpath, which could potentially cause issues, especially considering that the default Hadoop version is already 3.2.0 while most Hive versions supported by the `IsolatedClientLoader` is still using Hadoop 2.x or even lower.
### Does this PR introduce _any_ user-facing change?
This affects Spark users in one scenario: when `spark.sql.hive.metastore.jars` is set to `maven` AND the Hadoop version specified in pom file cannot be downloaded, currently the behavior is to switch to _not_ share Hadoop classes, but with the PR it will share Hadoop classes with Spark.

### What changes were proposed in this pull request?
This PR proposes to migrate `LOAD DATA` to use `UnresolvedTable` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
Note that `LOAD DATA` is not supported for v2 tables.
### Why are the changes needed?
The changes allow consistent resolution behavior when resolving the table identifier. For example, the following is the current behavior:
```scala
sql("CREATE TEMPORARY VIEW t AS SELECT 1")
sql("CREATE DATABASE db")
sql("CREATE TABLE t (key INT, value STRING) USING hive")
sql("USE db")
sql("LOAD DATA LOCAL INPATH 'examples/src/main/resources/kv1.txt' INTO TABLE t") // Succeeds
```
With this change, `LOAD DATA` above fails with the following:
```
org.apache.spark.sql.AnalysisException: t is a temp view not table.; line 1 pos 0
at org.apache.spark.sql.catalyst.analysis.package$AnalysisErrorAt.failAnalysis(package.scala:42)
at org.apache.spark.sql.catalyst.analysis.Analyzer$ResolveTempViews$$anonfun$apply$7.$anonfun$applyOrElse$39(Analyzer.scala:865)
at scala.Option.foreach(Option.scala:407)
```
, which is expected since temporary view is resolved first and `LOAD DATA` doesn't support a temporary view.
### Does this PR introduce _any_ user-facing change?
After this PR, `LOAD DATA ... t` is resolved to a temp view `t` instead of table `db.t` in the above scenario.
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
This PR changes `HiveExternalCatalogVersionsSuite` to, by default, use a standard temporary directory to store the Spark binaries that it localizes. It additionally adds a new System property, `spark.test.cache-dir`, which can be used to define a static location into which the Spark binary will be localized to allow for sharing between test executions. If the System property is used, the downloaded binaries won't be deleted after the test runs.
### Why are the changes needed?
In SPARK-22356 (PR #19579), the `sparkTestingDir` used by `HiveExternalCatalogVersionsSuite` became hard-coded to enable re-use of the downloaded Spark tarball between test executions:
```
// For local test, you can set `sparkTestingDir` to a static value like `/tmp/test-spark`, to
// avoid downloading Spark of different versions in each run.
private val sparkTestingDir = new File("/tmp/test-spark")
```
However this doesn't work, since it gets deleted every time:
```
override def afterAll(): Unit = {
try {
Utils.deleteRecursively(wareHousePath)
Utils.deleteRecursively(tmpDataDir)
Utils.deleteRecursively(sparkTestingDir)
} finally {
super.afterAll()
}
}
```
It's bad that we're hard-coding to a `/tmp` directory, as in some cases this is not the proper place to store temporary files. We're not currently making any good use of it.
### Does this PR introduce _any_ user-facing change?
Developer-facing changes only, as this is in a test.

```
In this PR, we gather all valid config to the cloned conf of `sharedState` during being constructed, well, actually only `spark.sql.warehouse.dir` is missing. Then we use this conf as defaults for `RESET` Command.
`SparkSession.clearActiveSession/clearDefaultSession` will make the shared state invisible and unsharable. They will be internal only soon (confirmed with Wenchen), so cases with them called will not be a problem.
### Why are the changes needed?
bugfix for programming API to call RESET while users creating SparkContext first and config SparkSession later.
### Does this PR introduce _any_ user-facing change?
yes, before this change when you use programming API and call RESET, all configs will be reset to SparkContext.conf, now they go to SparkSession.sharedState.conf

### What changes were proposed in this pull request?
1. Replace the metadata key `org.apache.spark.int96NoRebase` by `org.apache.spark.legacyINT96`.
2. Change the condition when new key should be saved to parquet metadata: it should be saved when the SQL config `spark.sql.legacy.parquet.int96RebaseModeInWrite` is set to `LEGACY`.
3. Change handling the metadata key in read:
- If there is no the key in parquet metadata, take the rebase mode from the SQL config: `spark.sql.legacy.parquet.int96RebaseModeInRead`
- If parquet files were saved by Spark < 3.1.0, use the `LEGACY` rebasing mode for INT96 type.
- For files written by Spark >= 3.1.0, if the `org.apache.spark.legacyINT96` presents in metadata, perform rebasing otherwise don't.
### Why are the changes needed?
- To not increase parquet size by default when `spark.sql.legacy.parquet.int96RebaseModeInWrite` is `EXCEPTION` after https://github.com/apache/spark/pull/30121.
- To have the implementation similar to `org.apache.spark.legacyDateTime`
- To minimise impact on other subsystems that are based on file sizes like gathering statistics.

Support `spark.sql.hive.metastore.jars` use HDFS location.
When user need to use path to set hive metastore jars, you should set
`spark.sql.hive.metasstore.jars=path` and set real path in `spark.sql.hive.metastore.jars.path`
since we use `File.pathSeperator` to split path, but `FIle.pathSeparator` is `:` in unix, it will split hdfs location `hdfs://nameservice/xx`. So add new config `spark.sql.hive.metastore.jars.path` to set comma separated paths.
To keep both two way supported

### What changes were proposed in this pull request?
This switches Spark to use shaded Hadoop clients, namely hadoop-client-api and hadoop-client-runtime, for Hadoop 3.x. For Hadoop 2.7, we'll still use the same modules such as hadoop-client.
In order to still keep default Hadoop profile to be hadoop-3.2, this defines the following Maven properties:
```
hadoop-client-api.artifact
hadoop-client-runtime.artifact
hadoop-client-minicluster.artifact
```
which default to:
```
hadoop-client-api
hadoop-client-runtime
hadoop-client-minicluster
```
but all switch to `hadoop-client` when the Hadoop profile is hadoop-2.7. A side affect from this is we'll import the same dependency multiple times. For this I have to disable Maven enforcer `banDuplicatePomDependencyVersions`.
Besides above, there are the following changes:
- explicitly add a few dependencies which are imported via transitive dependencies from Hadoop jars, but are removed from the shaded client jars.
- removed the use of `ProxyUriUtils.getPath` from `ApplicationMaster` which is a server-side/private API.
- modified `IsolatedClientLoader` to exclude `hadoop-auth` jars when Hadoop version is 3.x. This change should only matter when we're not sharing Hadoop classes with Spark (which is _mostly_ used in tests).
### Why are the changes needed?
This serves two purposes:
- to unblock Spark from upgrading to Hadoop 3.2.2/3.3.0+. Latest Hadoop versions have upgraded to use Guava 27+ and in order to adopt the latest Hadoop versions in Spark, we'll need to resolve the Guava conflicts. This takes the approach by switching to shaded client jars provided by Hadoop.
- avoid pulling 3rd party dependencies from Hadoop and avoid potential future conflicts.
### Does this PR introduce _any_ user-facing change?
When people use Spark with `hadoop-provided` option, they should make sure class path contains `hadoop-client-api` and `hadoop-client-runtime` jars. In addition, they may need to make sure these jars appear before other Hadoop jars in the order. Otherwise, classes may be loaded from the other non-shaded Hadoop jars and cause potential conflicts.

2. Update the SQL migration guide.
### Why are the changes needed?
Current default value `LEGACY` may lead to shifting timestamps in read or in write. We should leave the decision about rebasing to users.
### Does this PR introduce _any_ user-facing change?
Yes

### What changes were proposed in this pull request?
Currently, actual non-dynamic partition pruning is executed in the optimizer phase (PruneFileSourcePartitions) if an input relation has a catalog file index. The current code assumes the same partition filters are generated again in FileSourceStrategy and passed into FileSourceScanExec. FileSourceScanExec uses the partition filters when listing files, but these non-dynamic partition filters do nothing because unnecessary partitions are already pruned in advance, so the filters are mainly used for explain output in this case. If a WHERE clause has DNF-ed predicates, FileSourceStrategy cannot extract the same filters with PruneFileSourcePartitions and then PartitionFilters is not shown in explain output.
This patch proposes to extract partition filters in FileSourceStrategy and HiveStrategy with `extractPredicatesWithinOutputSet` added in https://github.com/apache/spark/pull/29101/files#diff-6be42cfa3c62a7536b1eb1d6447c073c again, then It will show the partially pushed down partition filter in explain().
### Why are the changes needed?
without the patch, the explained plan is inconsistent with what is actually executed
<b>without the change </b> the explained plan of `"SELECT * FROM t WHERE p = '1' OR (p = '2' AND i = 1)"` for datasource and hive tables are like the following respectively (missing pushed down partition filters)
```

### What changes were proposed in this pull request?
As [SPARK-13860](https://issues.apache.org/jira/browse/SPARK-13860) stated, TPCDS Query 39 returns wrong results using SparkSQL. The root cause is that when stddev_samp is applied to a single element set, with TPCDS answer, it return null; as in SparkSQL, it return Double.NaN which caused the wrong result.
Add an extra legacy config to fallback into the NaN logical, and return null by default to align with TPCDS standard.
### Why are the changes needed?
SQL correctness issue.
### Does this PR introduce any user-facing change?
Yes. See sql-migration-guide
In Spark 3.1, statistical aggregation function includes `std`, `stddev`, `stddev_samp`, `variance`, `var_samp`, `skewness`, `kurtosis`, `covar_samp`, `corr` will return `NULL` instead of `Double.NaN` when `DivideByZero` occurs during expression evaluation, for example, when `stddev_samp` applied on a single element set. In Spark version 3.0 and earlier, it will return `Double.NaN` in such case. To restore the behavior before Spark 3.1, you can set `spark.sql.legacy.statisticalAggregate` to `true`.
### How was this patch tested?
Updated DataFrameAggregateSuite/DataFrameWindowFunctionsSuite to test both default and legacy behavior.
Adjust DataFrameWindowFunctionsSuite/SQLQueryTestSuite and some R case to update to the default return null behavior.

This PR proposes to migrate `DESCRIBE tbl colname` to use `UnresolvedTableOrView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
### Why are the changes needed?
The current behavior is not consistent between v1 and v2 commands when resolving a temp view.
In v2, the `t` in the following example is resolved to a table:
```scala
sql("CREATE TABLE testcat.ns.t (id bigint) USING foo")
sql("CREATE TEMPORARY VIEW t AS SELECT 2 as i")
sql("USE testcat.ns")
sql("DESCRIBE t i") // 't' is resolved to testcat.ns.t
Describing columns is not supported for v2 tables.;
org.apache.spark.sql.AnalysisException: Describing columns is not supported for v2 tables.;
```
whereas in v1, the `t` is resolved to a temp view:
```scala
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint) USING csv")
sql("CREATE TEMPORARY VIEW t AS SELECT 2 as i")
sql("USE spark_catalog.test")
sql("DESCRIBE t i").show // 't' is resolved to a temp view
+---------+----------+
|info_name|info_value|
+---------+----------+
| col_name| i|
|data_type| int|
| comment| NULL|
+---------+----------+
```
### Does this PR introduce _any_ user-facing change?
After this PR, `DESCRIBE t i` is resolved to a temp view `t` instead of `testcat.ns.t`.
### How was this patch tested?
Added a new test

### What changes were proposed in this pull request?
When we create a UDAF function use class extended `UserDefinedAggregeteFunction`, when we call the function, in support hive mode, in HiveSessionCatalog, it will call super.makeFunctionExpression,
but it will catch error such as the function need 2 parameter and we only give 1, throw exception only show
```
No handler for UDF/UDAF/UDTF xxxxxxxx
```
This is confused for develop , we should show error thrown by super method too,
For this pr's UT :
Before change, throw Exception like
```
No handler for UDF/UDAF/UDTF 'org.apache.spark.sql.hive.execution.LongProductSum'; line 1 pos 7
```
After this pr, throw exception
```
Spark UDAF Error: Invalid number of arguments for function longProductSum. Expected: 2; Found: 1;
Hive UDF/UDAF/UDTF Error: No handler for UDF/UDAF/UDTF 'org.apache.spark.sql.hive.execution.LongProductSum'; line 1 pos 7
```
### Why are the changes needed?
Show more detail error message when define UDAF
### Does this PR introduce _any_ user-facing change?
People will see more detail error message when use spark sql's UDAF in hive support Mode

### What changes were proposed in this pull request?
As of today,
- SPARK-30034 Apache Spark 3.0.0 switched its default Hive execution engine from Hive 1.2 to Hive 2.3. This removes the direct dependency to the forked Hive 1.2.1 in maven repository.
- SPARK-32981 Apache Spark 3.1.0(`master` branch) removed Hive 1.2 related artifacts from Apache Spark binary distributions.
This PR(SPARK-20202) aims to remove the following usage of unofficial Apache Hive fork completely from Apache Spark master for Apache Spark 3.1.0.
```
<hive.group>org.spark-project.hive</hive.group>
<hive.version>1.2.1.spark2</hive.version>
```
For the forked Hive 1.2.1.spark2 users, Apache Spark 2.4(LTS) and 3.0 (~ 2021.12) will provide it.
### Why are the changes needed?
- First, Apache Spark community should not use the unofficial forked release of another Apache project.
- Second, Apache Hive 1.2.1 was released at 2015-06-26 and the forked Hive `1.2.1.spark2` exposed many unfixable bugs in Apache because the forked `1.2.1.spark2` is not maintained at all. Apache Hive 2.3.0 was released at 2017-07-19 and it has been used with less number of bugs compared with `1.2.1.spark2`. Many bugs still exist in `hive-1.2` profile and new Apache Spark unit tests are added with `HiveUtils.isHive23` condition so far.
### Does this PR introduce _any_ user-facing change?
No. This is a dev-only change. PRBuilder will not accept `[test-hive1.2]` on master and `branch-3.1`.
### How was this patch tested?
1. SBT/Hadoop 3.2/Hive 2.3 (https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/129366)
2. SBT/Hadoop 2.7/Hive 2.3 (https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/129382)

### What changes were proposed in this pull request?
This PR is to add support to decide bucketed table scan dynamically based on actual query plan. Currently bucketing is enabled by default (`spark.sql.sources.bucketing.enabled`=true), so for all bucketed tables in the query plan, we will use bucket table scan (all input files per the bucket will be read by same task). This has the drawback that if the bucket table scan is not benefitting at all (no join/groupby/etc in the query), we don't need to use bucket table scan as it would restrict the # of tasks to be # of buckets and might hurt parallelism.
The feature is to add a physical plan rule right after `EnsureRequirements`:
The rule goes through plan nodes. For all operators which has "interesting partition" (i.e., require `ClusteredDistribution` or `HashClusteredDistribution`), check if the sub-plan for operator has `Exchange` and bucketed table scan (and only allow certain operators in plan (i.e. `Scan/Filter/Project/Sort/PartialAgg/etc`.), see details in `DisableUnnecessaryBucketedScan.disableBucketWithInterestingPartition`). If yes, disable the bucketed table scan in the sub-plan. In addition, disabling bucketed table scan if there's operator with interesting partition along the sub-plan.
Why the algorithm works is that if there's a shuffle between the bucketed table scan and operator with interesting partition, then bucketed table scan partitioning will be destroyed by the shuffle operator in the middle, and we don't need bucketed table scan for sure.
The idea of "interesting partition" is inspired from "interesting order" in "Access Path Selection in a Relational Database Management System"(http://www.inf.ed.ac.uk/teaching/courses/adbs/AccessPath.pdf), after discussion with cloud-fan .
### Why are the changes needed?
To avoid unnecessary bucketed scan in the query, and this is prerequisite for https://github.com/apache/spark/pull/29625 (decide bucketed sorted scan dynamically will be added later in that PR).
### Does this PR introduce _any_ user-facing change?
A new config `spark.sql.sources.bucketing.autoBucketedScan.enabled` is introduced which set to false by default (the rule is disabled by default as it can regress cached bucketed table query, see discussion in https://github.com/apache/spark/pull/29804#issuecomment-701151447). User can opt-in/opt-out by enabling/disabling the config, as we found in prod, some users rely on assumption of # of tasks == # of buckets when reading bucket table to precisely control # of tasks. This is a bad assumption but it does happen on our side, so leave a config here to allow them opt-out for the feature.
### How was this patch tested?
Added unit tests in `DisableUnnecessaryBucketedScanSuite.scala`

### What changes were proposed in this pull request?
This pr aims to add a new `table` API in DataStreamReader, which is similar to the table API in DataFrameReader.
### Why are the changes needed?
Users can directly use this API to get a Streaming DataFrame on a table. Below is a simple example:
Application 1 for initializing and starting the streaming job:
```
val path = "/home/yuanjian.li/runtime/to_be_deleted"
val tblName = "my_table"
// Write some data to `my_table`
spark.range(3).write.format("parquet").option("path", path).saveAsTable(tblName)
// Read the table as a streaming source, write result to destination directory
val table = spark.readStream.table(tblName)
table.writeStream.format("parquet").option("checkpointLocation", "/home/yuanjian.li/runtime/to_be_deleted_ck").start("/home/yuanjian.li/runtime/to_be_deleted_2")
```
Application 2 for appending new data:
```
// Append new data into the path
spark.range(5).write.format("parquet").option("path", "/home/yuanjian.li/runtime/to_be_deleted").mode("append").save()
```
Check result:
```
// The desitination directory should contains all written data
spark.read.parquet("/home/yuanjian.li/runtime/to_be_deleted_2").show()
```
### Does this PR introduce _any_ user-facing change?
Yes, a new API added.

### What changes were proposed in this pull request?
In current mode, when explain a SQL plan with HiveTableRelation, it will show so many info about HiveTableRelation's prunedPartition, this make plan hard to read, this pr make this information simpler.
Before:
For UT
```
test("Make HiveTableScanExec message simple") {
withSQLConf("hive.exec.dynamic.partition.mode" -> "nonstrict") {
withTable("df") {
spark.range(30)
.select(col("id"), col("id").as("k"))
.write
.partitionBy("k")
.format("hive")
.mode("overwrite")
.saveAsTable("df")
val df = sql("SELECT df.id, df.k FROM df WHERE df.k < 2")
df.explain(true)
}
}
}
```
After this pr will show
```
== Parsed Logical Plan ==
'Project ['df.id, 'df.k]
+- 'Filter ('df.k < 2)
+- 'UnresolvedRelation [df], []
== Analyzed Logical Plan ==
id: bigint, k: bigint
Project [id#11L, k#12L]
+- Filter (k#12L < cast(2 as bigint))
+- SubqueryAlias spark_catalog.default.df
+- HiveTableRelation [`default`.`df`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, Data Cols: [id#11L], Partition Cols: [k#12L]]
== Optimized Logical Plan ==
Filter (isnotnull(k#12L) AND (k#12L < 2))
+- HiveTableRelation [`default`.`df`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, Data Cols: [id#11L], Partition Cols: [k#12L], Pruned Partitions: [(k=0), (k=1)]]
== Physical Plan ==
Scan hive default.df [id#11L, k#12L], HiveTableRelation [`default`.`df`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, Data Cols: [id#11L], Partition Cols: [k#12L], Pruned Partitions: [(k=0), (k=1)]], [isnotnull(k#12L), (k#12L < 2)]
```
In my pr, I will construct `HiveTableRelation`'s `simpleString` method to avoid show too much unnecessary info in explain plan. compared to what we had before，I decrease the detail metadata of each partition and only retain the partSpec to show each partition was pruned. Since for detail information, we always don't see this in Plan but to use DESC EXTENDED statement.

### What changes were proposed in this pull request?
This PR refactors the way we propagate the options from the `SparkSession.Builder` to the` SessionState`. This currently done via a mutable map inside the SparkSession. These setting settings are then applied **after** the Session. This is a bit confusing when you expect something to be set when constructing the `SessionState`. This PR passes the options as a constructor parameter to the `SessionStateBuilder` and this will set the options when the configuration is created.
### Why are the changes needed?
It makes it easier to reason about the configurations set in a SessionState than before. We recently had an incident where someone was using `SparkSessionExtensions` to create a planner rule that relied on a conf to be set. While this is in itself probably incorrect usage, it still illustrated this somewhat funky behavior.

I noticed that the code generation of `SafeProjection` failed in the existing test (https://issues.apache.org/jira/browse/SPARK-32828) but it passed because `FALLBACK` was set at `CODEGEN_FACTORY_MODE` (by default) in `SharedSparkSession`.

### What changes were proposed in this pull request?
Change `CreateFunctionCommand` code that add class check before create function.
### Why are the changes needed?
We have different behavior between create permanent function and temporary function when function class is invaild. e.g.,
```
create function f as 'test.non.exists.udf';
-- Time taken: 0.104 seconds
create temporary function f as 'test.non.exists.udf'
-- Error in query: Can not load class 'test.non.exists.udf' when registering the function 'f', please make sure it is on the classpath;
```
And Hive also fails both of them.
### Does this PR introduce _any_ user-facing change?
Yes, user will get exception when create a invalid udf.
### How was this patch tested?
New test.

### Why are the changes needed?
Currently, `DataFrameReader.table` ignores the specified options. The options specified like the following are lost.
```
val df = spark.read
.option("partitionColumn", "id")
.option("lowerBound", "0")
.option("upperBound", "3")
.option("numPartitions", "2")

- Test TEXTFILE together with the PARQUET and ORC file formats in `HiveSerDeReadWriteSuite`

### Why are the changes needed?
- To improve test coverage, and test other row SerDe - `org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe`.
- The removed test is not needed anymore because the bug reported in SPARK-32594 is triggered by the TEXTFILE file format too.

### What changes were proposed in this pull request?
Fix `DaysWritable` by overriding parent's method `def get(doesTimeMatter: Boolean): Date` from `DateWritable` instead of `Date get()` because the former one uses the first one. The bug occurs because `HiveOutputWriter.write()` call `def get(doesTimeMatter: Boolean): Date` transitively with default implementation from the parent class `DateWritable` which doesn't respect date rebases and uses not initialized `daysSinceEpoch` (0 which `1970-01-01`).
### Why are the changes needed?
The changes fix the bug:
```sql
spark-sql> CREATE TABLE table1 (d date);
spark-sql> INSERT INTO table1 VALUES (date '2020-08-11');
spark-sql> SELECT * FROM table1;
1970-01-01
```
The expected result of the last SQL statement must be **2020-08-11** but got **1970-01-01**.
### Does this PR introduce _any_ user-facing change?
Yes. After the fix, `INSERT` work correctly:
```sql
spark-sql> SELECT * FROM table1;
2020-08-11
```

Signed-off-by: Wenchen Fan <wenchen@databricks.com>
### What changes were proposed in this pull request?
Get table names directly from a sequence of Hive tables in `HiveClientImpl.listTablesByType()` by skipping conversions Hive tables to Catalog tables.
### Why are the changes needed?
A Hive metastore can be shared across many clients. A client can create tables using a SerDe which is not available on other clients, for instance `ROW FORMAT SERDE "com.ibm.spss.hive.serde2.xml.XmlSerDe"`. In the current implementation, other clients get the following exception while getting views:
```
java.lang.RuntimeException: MetaException(message:java.lang.ClassNotFoundException Class com.ibm.spss.hive.serde2.xml.XmlSerDe not found)
```
when `com.ibm.spss.hive.serde2.xml.XmlSerDe` is not available.
### Does this PR introduce _any_ user-facing change?
Yes. For example, `SHOW VIEWS` returns a list of views instead of throwing an exception.
### How was this patch tested?
- By existing test suites like:
```
$ build/sbt -Phive-2.3 "test:testOnly org.apache.spark.sql.hive.client.VersionsSuite"
```
- And manually:
1. Build Spark with Hive 1.2: `./build/sbt package -Phive-1.2 -Phive -Dhadoop.version=2.8.5`
2. Run spark-shell with a custom Hive SerDe, for instance download [json-serde-1.3.8-jar-with-dependencies.jar](https://github.com/cdamak/Twitter-Hive/blob/master/json-serde-1.3.8-jar-with-dependencies.jar) from https://github.com/cdamak/Twitter-Hive:
```
$ ./bin/spark-shell --jars ../Downloads/json-serde-1.3.8-jar-with-dependencies.jar
```
3. Create a Hive table using this SerDe:
```scala
scala> :paste
// Entering paste mode (ctrl-D to finish)
sql(s"""
|CREATE TABLE json_table2(page_id INT NOT NULL)
|ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'
|""".stripMargin)
// Exiting paste mode, now interpreting.
res0: org.apache.spark.sql.DataFrame = []
scala> sql("SHOW TABLES").show
+--------+-----------+-----------+
|database| tableName|isTemporary|
+--------+-----------+-----------+
| default|json_table2| false|
+--------+-----------+-----------+
scala> sql("SHOW VIEWS").show
+---------+--------+-----------+
|namespace|viewName|isTemporary|
+---------+--------+-----------+
+---------+--------+-----------+
```
4. Quit from the current `spark-shell` and run it without jars:
```
$ ./bin/spark-shell
```
5. Show views. Without the fix, it throws the exception:
```scala
scala> sql("SHOW VIEWS").show
20/08/06 10:53:36 ERROR log: error in initSerDe: java.lang.ClassNotFoundException Class org.openx.data.jsonserde.JsonSerDe not found

```
After the fix:
```scala
scala> sql("SHOW VIEWS").show
+---------+--------+-----------+
|namespace|viewName|isTemporary|
+---------+--------+-----------+
+---------+--------+-----------+
```

### What changes were proposed in this pull request?
This PR proposes to migrate the following function related commands to use `UnresolvedFunc` to resolve function identifier:
- DROP FUNCTION
- DESCRIBE FUNCTION
- SHOW FUNCTIONS
`DropFunctionStatement`, `DescribeFunctionStatement` and `ShowFunctionsStatement` logical plans are replaced with `DropFunction`, `DescribeFunction` and `ShowFunctions` logical plans respectively, and each contains `UnresolvedFunc` as its child so that it can be resolved in `Analyzer`.
### Why are the changes needed?
Migrating to the new resolution framework, which resolves `UnresolvedFunc` in `Analyzer`.
### Does this PR introduce _any_ user-facing change?
The message of exception thrown when a catalog is resolved to v2 has been merged to:
`function is only supported in v1 catalog`
Previously, it printed out the command used. E.g.,:
`CREATE FUNCTION is only supported in v1 catalog`
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
This PR aims to use `command -v` in non-Window operating systems instead of executing the given command.
### Why are the changes needed?
1. `command` is POSIX-compatible
- **POSIX.1-2017**: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/command.html
2. `command` is faster and safer than the direct execution
- `command` doesn't invoke another process.
```scala
scala> sys.process.Process("ls").run().exitValue()
LICENSE
NOTICE
bin
doc
lib
man
res1: Int = 0
```
3. The existing way behaves inconsistently.
- `rm` cannot be checked.
**AS-IS**
```scala
scala> sys.process.Process("rm").run().exitValue()
usage: rm [-f | -i] [-dPRrvW] file ...
unlink file
res0: Int = 64
```
**TO-BE**
```
Welcome to Scala 2.13.3 (OpenJDK 64-Bit Server VM, Java 1.8.0_262).
Type in expressions for evaluation. Or try :help.
scala> sys.process.Process(Seq("sh", "-c", s"command -v ls")).run().exitValue()
/bin/ls
val res1: Int = 0
```
4. The existing logic is already broken in Scala 2.13 environment because it hangs like the following.
```scala
$ bin/scala

### What changes were proposed in this pull request?
In https://github.com/apache/spark/pull/28733 and #28805, CNF conversion is used to push down disjunctive predicates through join and partitions pruning.
It's a good improvement, however, converting all the predicates in CNF can lead to a very long result, even with grouping functions over expressions. For example, for the following predicate
```
(p0 = '1' AND p1 = '1') OR (p0 = '2' AND p1 = '2') OR (p0 = '3' AND p1 = '3') OR (p0 = '4' AND p1 = '4') OR (p0 = '5' AND p1 = '5') OR (p0 = '6' AND p1 = '6') OR (p0 = '7' AND p1 = '7') OR (p0 = '8' AND p1 = '8') OR (p0 = '9' AND p1 = '9') OR (p0 = '10' AND p1 = '10') OR (p0 = '11' AND p1 = '11') OR (p0 = '12' AND p1 = '12') OR (p0 = '13' AND p1 = '13') OR (p0 = '14' AND p1 = '14') OR (p0 = '15' AND p1 = '15') OR (p0 = '16' AND p1 = '16') OR (p0 = '17' AND p1 = '17') OR (p0 = '18' AND p1 = '18') OR (p0 = '19' AND p1 = '19') OR (p0 = '20' AND p1 = '20')
```
will be converted into a long query(130K characters) in Hive metastore, and there will be error:
```
javax.jdo.JDOException: Exception thrown when executing query : SELECT DISTINCT 'org.apache.hadoop.hive.metastore.model.MPartition' AS NUCLEUS_TYPE,A0.CREATE_TIME,A0.LAST_ACCESS_TIME,A0.PART_NAME,A0.PART_ID,A0.PART_NAME AS NUCORDER0 FROM PARTITIONS A0 LEFT OUTER JOIN TBLS B0 ON A0.TBL_ID = B0.TBL_ID LEFT OUTER JOIN DBS C0 ON B0.DB_ID = C0.DB_ID WHERE B0.TBL_NAME = ? AND C0."NAME" = ? AND ((((((A0.PART_NAME LIKE '%/p1=1' ESCAPE '\' ) OR (A0.PART_NAME LIKE '%/p1=2' ESCAPE '\' )) OR (A0.PART_NAME LIKE '%/p1=3' ESCAPE '\' )) OR ((A0.PART_NAME LIKE '%/p1=4' ESCAPE '\' ) O ...
```
Essentially, we just need to traverse predicate and extract the convertible sub-predicates like what we did in https://github.com/apache/spark/pull/24598. There is no need to maintain the CNF result set.
### Why are the changes needed?
A better implementation for pushing down disjunctive and complex predicates. The pushed down predicates is always equal or shorter than the CNF result.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?

Spark sql commands are failing on selecting the orc tables
Steps to reproduce
Example 1 -
Prerequisite - This is the location(/Users/test/tpcds_scale5data/date_dim) for orc data which is generated by the hive.
```
val table = """CREATE TABLE `date_dim` (
`d_date_sk` INT,
`d_date_id` STRING,
`d_date` TIMESTAMP,
`d_month_seq` INT,
`d_week_seq` INT,

`d_year` INT,
`d_dow` INT,
`d_moy` INT,
`d_dom` INT,
`d_qoy` INT,
`d_fy_year` INT,
`d_fy_quarter_seq` INT,

spark.sql(table).collect
val u = """select date_dim.d_date_id from date_dim limit 5"""
spark.sql(u).collect
```
Example 2
```
val table = """CREATE TABLE `test_orc_data` (
`_col1` INT,
`_col2` STRING,
`_col3` INT)

spark.sql(table).collect
spark.sql("insert into test_orc_data values(13, '155', 2020)").collect
val df = """select _col2 from test_orc_data limit 5"""

### What changes were proposed in this pull request?
Same as https://github.com/apache/spark/pull/29078 and https://github.com/apache/spark/pull/28971 . This makes the rest of the default modules (i.e. those you get without specifying `-Pyarn` etc) compile under Scala 2.13. It does not close the JIRA, as a result. this also of course does not demonstrate that tests pass yet in 2.13.
Note, this does not fix the `repl` module; that's separate.
### Why are the changes needed?
Eventually, we need to support a Scala 2.13 build, perhaps in Spark 3.1.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Existing tests. (2.13 was not tested; this is about getting it to compile without breaking 2.12)

### What changes were proposed in this pull request?
This PR will remove references to these "blacklist" and "whitelist" terms besides the blacklisting feature as a whole, which can be handled in a separate JIRA/PR.
This touches quite a few files, but the changes are straightforward (variable/method/etc. name changes) and most quite self-contained.
### Why are the changes needed?
As per discussion on the Spark dev list, it will be beneficial to remove references to problematic language that can alienate potential community members. One such reference is "blacklist" and "whitelist". While it seems to me that there is some valid debate as to whether these terms have racist origins, the cultural connotations are inescapable in today's world.
### Does this PR introduce _any_ user-facing change?
In the test file `HiveQueryFileTest`, a developer has the ability to specify the system property `spark.hive.whitelist` to specify a list of Hive query files that should be tested. This system property has been renamed to `spark.hive.includelist`. The old property has been kept for compatibility, but will log a warning if used. I am open to feedback from others on whether keeping a deprecated property here is unnecessary given that this is just for developers running tests.
### How was this patch tested?
Existing tests should be suitable since no behavior changes are expected as a result of this PR.

### What changes were proposed in this pull request?
This PR aims to drop Python 2.7, 3.4 and 3.5.
Roughly speaking, it removes all the widely known Python 2 compatibility workarounds such as `sys.version` comparison, `__future__`. Also, it removes the Python 2 dedicated codes such as `ArrayConstructor` in Spark.
### Why are the changes needed?
1. Unsupport EOL Python versions
2. Reduce maintenance overhead and remove a bit of legacy codes and hacks for Python 2.
3. PyPy2 has a critical bug that causes a flaky test, SPARK-28358 given my testing and investigation.
4. Users can use Python type hints with Pandas UDFs without thinking about Python version
5. Users can leverage one latest cloudpickle, https://github.com/apache/spark/pull/28950. With Python 3.8+ it can also leverage C pickle.
### Does this PR introduce _any_ user-facing change?
Yes, users cannot use Python 2.7, 3.4 and 3.5 in the upcoming Spark version.
### How was this patch tested?
Manually tested and also tested in Jenkins.

### What changes were proposed in this pull request?
This change replaces the world slave with alternatives matching the context.
### Why are the changes needed?
There is no need to call things slave, we might as well use better clearer names.
### Does this PR introduce _any_ user-facing change?
Yes, the ouput JSON does change. To allow backwards compatibility this is an additive change.
The shell scripts for starting & stopping workers are renamed, and for backwards compatibility old scripts are added to call through to the new ones while printing a deprecation message to stderr.

### What changes were proposed in this pull request?
* Renamed hive transform scrip class `hive/execution/ScriptTransformationExec` to `hive/execution/HiveScriptTransformationExec` (don't rename file)
* Extract class `BaseScriptTransformationExec ` about common code used across `SparkScriptTransformationExec(next pr add this)` and `HiveScriptTransformationExec`
* Extract class `BaseScriptTransformationWriterThread` of writing data thread across `SparkScriptTransformationWriterThread(added next for support transform in sql/core )` and `HiveScriptTransformationWriterThread` ,
* `HiveScriptTransformationWriterThread` additionally supports Hive serde format
* Rename current `Script` strategies in hive module to `HiveScript`, in next pr will add `SparkScript` strategies for support transform in sql/core.
Todo List;
- Support transform in sql/core base on `BaseScriptTransformationExec`, which would run script operator in SQL mode (without Hive).
The output of script would be read as a string and column values are extracted by using a delimiter (default : tab character)
- For Hive, by default only serde's must be used, and without hive we can run without serde
- Cleanup past hacks that are observed (and people suggest / report)， such as
- [Solve string value error about Date/Timestamp in ScriptTransform](https://issues.apache.org/jira/browse/SPARK-31947)
- [support use transform with aggregation](https://issues.apache.org/jira/browse/SPARK-28227)
- [support array/map as transform's input](https://issues.apache.org/jira/browse/SPARK-22435)
- Use code-gen projection to serialize rows to output stream()
### Why are the changes needed?
Support run transform in SQL mode without hive
### Does this PR introduce any user-facing change?

### What changes were proposed in this pull request?
This PR aims to run the Spark tests in Github Actions.
To briefly explain the main idea:
- Reuse `dev/run-tests.py` with SBT build
- Reuse the modules in `dev/sparktestsupport/modules.py` to test each module
- Pass the modules to test into `dev/run-tests.py` directly via `TEST_ONLY_MODULES` environment variable. For example, `pyspark-sql,core,sql,hive`.
- `dev/run-tests.py` _does not_ take the dependent modules into account but solely the specified modules to test.
Another thing to note might be `SlowHiveTest` annotation. Running the tests in Hive modules takes too much so the slow tests are extracted and it runs as a separate job. It was extracted from the actual elapsed time in Jenkins:
So, Hive tests are separated into to jobs. One is slow test cases, and the other one is the other test cases.
_Note that_ the current GitHub Actions build virtually copies what the default PR builder on Jenkins does (without other profiles such as JDK 11, Hadoop 2, etc.). The only exception is Kinesis https://github.com/apache/spark/pull/29057/files#diff-04eb107ee163a50b61281ca08f4e4c7bR23
### Why are the changes needed?
Last week and onwards, the Jenkins machines became very unstable for many reasons:
- Apparently, the machines became extremely slow. Almost all tests can't pass.
- One machine (worker 4) started to have the corrupt `.m2` which fails the build.
- Documentation build fails time to time for an unknown reason in Jenkins machine specifically. This is disabled for now at https://github.com/apache/spark/pull/29017.
- Almost all PRs are basically blocked by this instability currently.
The advantages of using Github Actions:
- To avoid depending on few persons who can access to the cluster.
- To reduce the elapsed time in the build - we could split the tests (e.g., SQL, ML, CORE), and run them in parallel so the total build time will significantly reduce.
- To control the environment more flexibly.
- Other contributors can test and propose to fix Github Actions configurations so we can distribute this build management cost.
Note that:
- The current build in Jenkins takes _more than 7 hours_. With Github actions it takes _less than 2 hours_
- We can now control the environments especially for Python easily.
- The test and build look more stable than the Jenkins'.
### Does this PR introduce _any_ user-facing change?
No, dev-only change.

### What changes were proposed in this pull request?
Force to initialize Hadoop VersionInfo in HiveExternalCatalog to make sure Hive can get the Hadoop version when using the isolated classloader.
### Why are the changes needed?
This is a regression in Spark 3.0.0 because we switched the default Hive execution version from 1.2.1 to 2.3.7.
Spark allows the user to set `spark.sql.hive.metastore.jars` to specify jars to access Hive Metastore. These jars are loaded by the isolated classloader. Because we also share Hadoop classes with the isolated classloader, the user doesn't need to add Hadoop jars to `spark.sql.hive.metastore.jars`, which means when we are using the isolated classloader, hadoop-common jar is not available in this case. If Hadoop VersionInfo is not initialized before we switch to the isolated classloader, and we try to initialize it using the isolated classloader (the current thread context classloader), it will fail and report `Unknown` which causes Hive to throw the following exception:

Technically, This is indeed an issue of Hadoop VersionInfo which has been fixed: https://issues.apache.org/jira/browse/HADOOP-14067. But since we are still supporting old Hadoop versions, we should fix it.
Why this issue starts to happen in Spark 3.0.0?
In Spark 2.4.x, we use Hive 1.2.1 by default. It will trigger `VersionInfo` initialization in the static codes of `Hive` class. This will happen when we load `HiveClientImpl` class because `HiveClientImpl.clent` method refers to `Hive` class. At this moment, the thread context classloader is not using the isolcated classloader, so it can access hadoop-common jar on the classpath and initialize it correctly.
In Spark 3.0.0, we use Hive 2.3.7. The static codes of `Hive` class are not accessing `VersionInfo` because of the change in https://issues.apache.org/jira/browse/HIVE-11657. Instead, accessing `VersionInfo` happens when creating a `Hive` object (See the above stack trace). This happens here https://github.com/apache/spark/blob/v3.0.0/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L260. But we switch to the isolated classloader before calling `HiveClientImpl.client` (See https://github.com/apache/spark/blob/v3.0.0/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L283). This is exactly what I mentioned above: `If Hadoop VersionInfo is not initialized before we switch to the isolated classloader, and we try to initialize it using the isolated classloader (the current thread context classloader), it will fail`
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
The new regression test added in this PR.
Note that the new UT doesn't fail with the default profiles (-Phadoop-3.2) because it's already fixed at Hadoop 3.1. Please use the following to verify this.

### What changes were proposed in this pull request?
This PR proposes to partially reverts the simple string in `NullType` at https://github.com/apache/spark/pull/28833: `NullType.simpleString` back from `unknown` to `null`.
### Why are the changes needed?
- Technically speaking, it's orthogonal with the issue itself, SPARK-20680.
- It needs some more discussion, see https://github.com/apache/spark/pull/28833#issuecomment-655277714
### Does this PR introduce _any_ user-facing change?
It reverts back the user-facing changes at https://github.com/apache/spark/pull/28833.
The simple string of `NullType` is back to `null`.
### How was this patch tested?
I just logically reverted. Jenkins should test it out.

### What changes were proposed in this pull request?
When somebody changed the type of partition's field, spark will throw ClassCastException. For example, we have a table like this:
```
drop table if exists cast_exception_test;
create table cast_exception_test(c1 int, c2 string) partitioned by (dt string) stored as orc;
insert into table cast_exception_test partition(dt='2020-04-08') values('1', 'jeff_1');
```
If you change the field's type in hive, query the old partition, spark will throw ClassCastException, but hive will not:
```
-- change the field's type using hive
alter table cast_exception_test change column c1 c1 string;
-- hive correct, but spark throws ClassCastException
select * from cast_exception_test where dt='2020-04-08';
```
### Why are the changes needed?
When the table has many fields, we don's known which field has been changed. If we print out log about this exception, it will very helpful for us to troubleshoot.
### Does this PR introduce _any_ user-facing change?
When the ClassCastException is caused by changed field's type, you can search which field has problem in exexutor logs:
```
20/04/09 17:22:05 ERROR hive.HadoopTableReader: Exception thrown in field <c1>
```
### How was this patch tested?
First, prepare the test data, the table is partitioned and stored as orc:
```
drop table if exists cast_exception_test;
create table cast_exception_test(c1 int, c2 string) partitioned by (dt string) stored as orc;
insert into table cast_exception_test partition(dt='2020-04-08') values('1', 'jeff_1');
```
Then, change the field's type in hive.
```
alter table cast_exception_test change column c1 c1 string;
```
Now the metadata of the table has been modified, but the partition's metadata which is stored in orc file or hive metastore's mysql is still old. So, query command throws ClassCastException in spark, because spark use table's metadata which is different from orc file's metadata. But hive use partition's metadata which is the same as orc file's metadata.
If you query the old partition, spark will thrown ClassCastException, but hive will not:
```
select * from cast_exception_test where dt='2020-04-08';
```

Context: The fix for SPARK-27296 introduced by #25024 allows `Aggregator` objects to appear in queries. This works fine for aggregators with atomic input types, e.g. `Aggregator[Double, _, _]`.
However it can cause a null pointer exception if the input type is `Array[_]`. This was historically considered an ignorable case for serialization of `UnresolvedMapObjects`, but the new ScalaAggregator class causes these expressions to be serialized over to executors because the resolve-and-bind is being deferred.
### What changes were proposed in this pull request?
A new rule `ResolveEncodersInScalaAgg` that performs the resolution of the expressions contained in the encoders so that properly resolved expressions are serialized over to executors.
### Why are the changes needed?
Applying an aggregator of the form `Aggregator[Array[_], _, _]` using `functions.udaf()` currently causes a null pointer error in Catalyst.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
A unit test has been added that does aggregation with array types for input, buffer, and output. I have done additional testing with my own custom aggregators in the spark REPL.

z void
In Spark2.0.x, the behaviour to read this view is normal:
>spark-sql> describe bad;
x int NULL
z void NULL

But in lastest Spark version, it failed with SparkException: Cannot recognize hive type string: void

This is a followup of https://github.com/apache/spark/pull/28760 to fix the remaining issues:

2. should consider data source options when inferring schema for file source
3. should consider data source options when getting the qualified path in file source v2.

We didn't catch these issues in https://github.com/apache/spark/pull/28760, because the test case is to check error when initializing the file system. If we initialize the file system multiple times during a simple read/write action, the test case actually only test the first time.

### What changes were proposed in this pull request?
Spark can't push down scan predicate condition of **Or**:
Such as if I have a table `default.test`, it's partition col is `dt`,
If we use query :
```
select * from default.test
where dt=20190625 or (dt = 20190626 and id in (1,2,3) )
```
In this case, Spark will resolve **Or** condition as one expression, and since this expr has reference of "id", then it can't been push down.
Base on pr https://github.com/apache/spark/pull/28733, In my PR , for SQL like
`select * from default.test`
`where dt = 20190626 or (dt = 20190627 and xxx="a") `
For this condition `dt = 20190626 or (dt = 20190627 and xxx="a" )`, it will been converted to CNF
```
(dt = 20190626 or dt = 20190627) and (dt = 20190626 or xxx = "a" )
```
then condition `dt = 20190626 or dt = 20190627` will be push down when partition pruning

### What changes were proposed in this pull request?
With SPARK-18107, we will disable the underlying replace(overwrite) and instead do delete in spark side and only do copy in hive side to bypass the performance issue - [HIVE-11940](https://issues.apache.org/jira/browse/HIVE-11940)
Conditionally, if the table location and partition location do not belong to the same `FileSystem`, We should not disable hive overwrite. Otherwise, hive will use the `FileSystem` instance belong to the table location to copy files, which will fail in `FileSystem#checkPath`
https://github.com/apache/hive/blob/rel/release-2.3.7/ql/src/java/org/apache/hadoop/hive/ql/metadata/Hive.java#L1657
In this PR, for Hive 2.0.0 and onwards, as [HIVE-11940](https://issues.apache.org/jira/browse/HIVE-11940) has been fixed, and there is no performance issue anymore. We should leave the overwrite logic to hive to avoid failure in `FileSystem#checkPath`
**NOTE THAT** For Hive 2.2.0 and earlier, if the table and partition locations do not belong together, we will still get the same error thrown by hive encryption check due to [HIVE-14380]( https://issues.apache.org/jira/browse/HIVE-14380) which need to fix in another ticket SPARK-31675.

### What changes were proposed in this pull request?
This patch effectively reverts SPARK-30098 via below changes:
* Removed the config
* Removed the changes done in parser rule
* Removed the usage of config in tests
* Removed tests which depend on the config
* Rolled back some tests to before SPARK-30098 which were affected by SPARK-30098
* Reflect the change into docs (migration doc, create table syntax)
### Why are the changes needed?
SPARK-30098 brought confusion and frustration on using create table DDL query, and we agreed about the bad effect on the change.
Please go through the [discussion thread](http://apache-spark-developers-list.1001551.n3.nabble.com/DISCUSS-Resolve-ambiguous-parser-rule-between-two-quot-create-table-quot-s-td29051i20.html) to see the details.
### Does this PR introduce _any_ user-facing change?
No, compared to Spark 2.4.x. End users tried to experiment with Spark 3.0.0 previews will see the change that the behavior is going back to Spark 2.4.x, but I believe we won't guarantee compatibility in preview releases.

### Why are the changes needed?
Currently, `HiveExternalCatalogVersionsSuite` is aborted in all Jenkins jobs except JDK11 Jenkins jobs which don't have old Spark releases supporting JDK11.

### What changes were proposed in this pull request?
This PR try to fix a bug in `org.apache.spark.sql.hive.execution.ScriptTransformationExec`. This bug appears in our online cluster. `ScriptTransformationExec` should throw an exception, when user uses a python script which contains parse error. But current implementation may miss this case of failure.
### Why are the changes needed?
When user uses a python script which contains a parse error, there will be no output. So `scriptOutputReader.next(scriptOutputWritable) <= 0` matches, then we use `checkFailureAndPropagate()` to check the `proc`. But the `proc` may still be alive and `writerThread.exception` is not defined, `checkFailureAndPropagate` cannot check this case of failure. In the end, the Spark SQL job runs successfully and returns no result. In fact, the SparK SQL job should fails and shows the exception properly.
For example, the error python script is blow.
``` python
# encoding: utf8
import unknow_module
import sys
for line in sys.stdin:
print line
```
The bug can be reproduced by running the following code in our cluter.
```
spark.range(100*100).toDF("index").createOrReplaceTempView("test")
spark.sql("select TRANSFORM(index) USING 'python error_python.py' as new_index from test").collect.foreach(println)

### What changes were proposed in this pull request?
When reading/writing datetime values that before the rebase switch day, from/to Avro/Parquet files, fail by default and ask users to set a config to explicitly do rebase or not.
### Why are the changes needed?
Rebase or not rebase have different behaviors and we should let users decide it explicitly. In most cases, users won't hit this exception as it only affects ancient datetime values.
### Does this PR introduce _any_ user-facing change?
Yes, now users will see an error when reading/writing dates before 1582-10-15 or timestamps before 1900-01-01 from/to Parquet/Avro files, with an error message to ask setting a config.

### What changes were proposed in this pull request?
Modified `RandomDataGenerator.forType` for DateType and TimestampType to generate special date//timestamp values with 0.5 probability. This will trigger dictionary encoding in Parquet datasource test HadoopFsRelationTest "test all data types". Currently, dictionary encoding is tested only for numeric types like ShortType.
### Why are the changes needed?
To extend test coverage. Currently, probability of testing of dictionary encoding in the test HadoopFsRelationTest "test all data types" for DateType and TimestampType is close to zero because dates/timestamps are uniformly distributed in wide range, and the chance of generating the same values is pretty low. In this way, parquet datasource cannot apply dictionary encoding for such column types.

### What changes were proposed in this pull request?
This PR addresses two things:
- `SHOW TBLPROPERTIES` should supports view (a regression introduced by #26921)
- `SHOW TBLPROPERTIES` on a temporary view should return empty result (2.4 behavior instead of throwing `AnalysisException`.
### Why are the changes needed?
It's a bug.
### Does this PR introduce any user-facing change?
Yes, now `SHOW TBLPROPERTIES` works on views:
```

### What changes were proposed in this pull request?
HiveClient instance is cross-session, the following configurations which are defined in HiveUtils and used to create it should be considered static:
1. spark.sql.hive.metastore.version - used to determine the hive version in Spark
2. spark.sql.hive.metastore.jars - hive metastore related jars location which is used by spark to create hive client
3. spark.sql.hive.metastore.sharedPrefixes and spark.sql.hive.metastore.barrierPrefixes - package names of classes that are shared or separated between SparkContextLoader and hive client class loader
Those are used only once when creating the hive metastore client. They should be static in SQLConf for retrieving them correctly. We should avoid them being changed by users with SET/RESET command.
Speaking of spark.sql.hive.version - the fake of the spark.sql.hive.metastore.version, it is used by jdbc/thrift client for backward compatibility.
### Why are the changes needed?
bugfix, these configurations should not be changed.
### Does this PR introduce any user-facing change?
Yes, the following set of configs are not allowed to change.

### What changes were proposed in this pull request?
Make `UnsafeKVExternalSorter` / `VariableLengthRowBasedKeyValueBatch ` also respect `UnsafeAlignedOffset` when reading the record and update some out of date comemnts.
### Why are the changes needed?
Since `BytesToBytesMap` respects `UnsafeAlignedOffset` when writing the record, `UnsafeKVExternalSorter` should also respect `UnsafeAlignedOffset` when reading the record from `BytesToBytesMap` otherwise it will causes data correctness issue.
Unlike `UnsafeKVExternalSorter` may reading records from `BytesToBytesMap`, `VariableLengthRowBasedKeyValueBatch` writes and reads records by itself. Thus, similar to #22053 and [comment](https://github.com/apache/spark/pull/22053#issuecomment-411975239) there, fix for `VariableLengthRowBasedKeyValueBatch` more likely an improvement for the support of SPARC platform.

### What changes were proposed in this pull request?
Previously, user can issue `SHOW TABLES` to get info of both tables and views.
This PR (SPARK-31113) implements `SHOW VIEWS` SQL command similar to HIVE to get views only.(https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-ShowViews)
**Hive** -- Only show view names
```
hive> SHOW VIEWS;
OK

```
**Spark(Hive-Compatible)** -- Only show view names, used in tests and `SparkSQLDriver` for CLI applications
```
SHOW VIEWS IN showdb;

### What changes were proposed in this pull request?
For now `SHOW CREATE TABLE` command doesn't support views, but `SHOW CREATE TABLE AS SERDE` supports it. Since the views syntax are the same between Hive DDL and Spark DDL, we should be able to support views in both two commands.
This is Hive syntax for creating views:
```
CREATE VIEW [IF NOT EXISTS] [db_name.]view_name [(column_name [COMMENT column_comment], ...) ]
[COMMENT view_comment]
[TBLPROPERTIES (property_name = property_value, ...)]
AS SELECT ...;
```
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateView
This is Spark syntax for creating views:
```
CREATE [OR REPLACE] [[GLOBAL] TEMPORARY] VIEW [IF NOT EXISTS [db_name.]view_name
create_view_clauses
AS query;
```
https://spark.apache.org/docs/3.0.0-preview/sql-ref-syntax-ddl-create-view.html
Looks like it is the same. We could support views in both commands.
This patch proposes to add views support to `SHOW CREATE TABLE`.
### Why are the changes needed?
To extend the view support of `SHOW CREATE TABLE`, so users can use `SHOW CREATE TABLE` to show Spark DDL for views.
### Does this PR introduce any user-facing change?
Yes. `SHOW CREATE TABLE` can be used to show Spark DDL for views.
### How was this patch tested?

### What changes were proposed in this pull request?
This patch proposes to cache Class instance for the UDF instance in HiveFunctionWrapper to fix the case where Hive simple UDF is somehow transformed (expression is copied) and evaluated later with another classloader (for the case current thread context classloader is somehow changed). In this case, Spark throws CNFE as of now.
It's only occurred for Hive simple UDF, as HiveFunctionWrapper caches the UDF instance whereas it doesn't do for `UDF` type. The comment says Spark has to create instance every time for UDF, so we cannot simply do the same. This patch caches Class instance instead, and switch current thread context classloader to which loads the Class instance.
This patch extends the test boundary as well. We only tested with GenericUDTF for SPARK-26560, and this patch actually requires only UDF. But to avoid regression for other types as well, this patch adds all available types (UDF, GenericUDF, AbstractGenericUDAFResolver, UDAF, GenericUDTF) into the boundary of tests.

- HiveContext
- createExternalTable APIs
### Why are the changes needed?

### What changes were proposed in this pull request?
In Spark CLI, we create a hive `CliSessionState` and it does not load the `hive-site.xml`. So the configurations in `hive-site.xml` will not take effects like other spark-hive integration apps.
Also, the warehouse directory is not correctly picked. If the `default` database does not exist, the `CliSessionState` will create one during the first time it talks to the metastore. The `Location` of the default DB will be neither the value of `spark.sql.warehousr.dir` nor the user-specified value of `hive.metastore.warehourse.dir`, but the default value of `hive.metastore.warehourse.dir `which will always be `/user/hive/warehouse`.
This PR fixes CLiSuite failure with the hive-1.2 profile in https://github.com/apache/spark/pull/27933.
In https://github.com/apache/spark/pull/27933, we fix the issue in JIRA by deciding the warehouse dir using all properties from spark conf and Hadoop conf, but properties from `--hiveconf` is not included, they will be applied to the `CliSessionState` instance after it initialized. When this command-line option key is `hive.metastore.warehouse.dir`, the actual warehouse dir is overridden. Because of the logic in Hive for creating the non-existing default database changed, that test passed with `Hive 2.3.6` but failed with `1.2`. So in this PR, Hadoop/Hive configurations are ordered by:
` spark.hive.xxx > spark.hadoop.xxx > --hiveconf xxx > hive-site.xml` througth `ShareState.loadHiveConfFile` before sessionState start
### Why are the changes needed?

### Does this PR introduce any user-facing change?
yes,
1. the non-exists default database will be created in the location specified by the users via `spark.sql.warehouse.dir` or `hive.metastore.warehouse.dir`, or the default value of `spark.sql.warehouse.dir` if none of them specified.
2. configurations from `hive-site.xml` will not override command-line options or the properties defined with `spark.hadoo(hive).` prefix in spark conf.

### What changes were proposed in this pull request?
This PR (SPARK-31238) aims the followings.
1. Modified ORC Vectorized Reader, in particular, OrcColumnVector v1.2 and v2.3. After the changes, it uses `DateTimeUtils. rebaseJulianToGregorianDays()` added by https://github.com/apache/spark/pull/27915 . The method performs rebasing days from the hybrid calendar (Julian + Gregorian) to Proleptic Gregorian calendar. It builds a local date in the original calendar, extracts date fields `year`, `month` and `day` from the local date, and builds another local date in the target calendar. After that, it calculates days from the epoch `1970-01-01` for the resulted local date.
2. Introduced rebasing dates while saving ORC files, in particular, I modified `OrcShimUtils. getDateWritable` v1.2 and v2.3, and returned `DaysWritable` instead of Hive's `DateWritable`. The `DaysWritable` class was added by the PR https://github.com/apache/spark/pull/27890 (and fixed by https://github.com/apache/spark/pull/27962). I moved `DaysWritable` from `sql/hive` to `sql/core` to re-use it in ORC datasource.
### Why are the changes needed?
For the backward compatibility with Spark 2.4 and earlier versions. The changes allow users to read dates/timestamps saved by previous version, and get the same result.
### Does this PR introduce any user-facing change?
Yes. Before the changes, loading the date `1200-01-01` saved by Spark 2.4.5 returns the following:
```scala
scala> spark.read.orc("/Users/maxim/tmp/before_1582/2_4_5_date_orc").show(false)
+----------+
|dt |
+----------+
|1200-01-08|
+----------+
```
After the changes
```scala
scala> spark.read.orc("/Users/maxim/tmp/before_1582/2_4_5_date_orc").show(false)
+----------+
|dt |
+----------+
|1200-01-01|
+----------+
```
### How was this patch tested?
- By running `OrcSourceSuite` and `HiveOrcSourceSuite`.
- Add new test `SPARK-31238: compatibility with Spark 2.4 in reading dates` to `OrcSuite` which reads an ORC file saved by Spark 2.4.5 via the commands:
```shell
$ export TZ="America/Los_Angeles"
```
```scala
scala> sql("select cast('1200-01-01' as date) dt").write.mode("overwrite").orc("/Users/maxim/tmp/before_1582/2_4_5_date_orc")
scala> spark.read.orc("/Users/maxim/tmp/before_1582/2_4_5_date_orc").show(false)
+----------+
|dt |
+----------+
|1200-01-01|
+----------+
```
- Add round trip test `SPARK-31238: rebasing dates in write`. The test `SPARK-31238: compatibility with Spark 2.4 in reading dates` confirms rebasing in read. So, we can check rebasing in write.

### What changes were proposed in this pull request?
Spark introduced CHAR type for hive compatibility but it only works for hive tables. CHAR type is never documented and is treated as STRING type for non-Hive tables.
However, this leads to confusing behaviors
**Apache Spark 3.0.0-preview2**
```
spark-sql> CREATE TABLE t(a CHAR(3));
spark-sql> INSERT INTO TABLE t SELECT 'a ';
spark-sql> SELECT a, length(a) FROM t;
a 2
```
**Apache Spark 2.4.5**
```
spark-sql> CREATE TABLE t(a CHAR(3));
spark-sql> INSERT INTO TABLE t SELECT 'a ';
spark-sql> SELECT a, length(a) FROM t;
a 3
```
According to the SQL standard, `CHAR(3)` should guarantee all the values are of length 3. Since `CHAR(3)` is treated as STRING so Spark doesn't guarantee it.
This PR forbids CHAR type in non-Hive tables as it's not supported correctly.
### Why are the changes needed?
avoid confusing/wrong behavior
### Does this PR introduce any user-facing change?
yes, now users can't create/alter non-Hive tables with CHAR type.

### What changes were proposed in this pull request?
In the PR, I propose to apply rebasing for all dates/timestamps in conversion functions `fromJavaDate()`, `toJavaDate()`, `toJavaTimestamp()` and `fromJavaTimestamp()`. The rebasing is performed via building a local date-time in an original calendar, extracting date-time fields from the result, and creating new local date-time in the target calendar.
### Why are the changes needed?
The changes are need to be compatible with previous Spark version (2.4.5 and earlier versions) not only before the Gregorian cutover date `1582-10-15` but also for dates after the date. For instance, Gregorian calendar implementation in Java 7 `java.util.GregorianCalendar` is not accurate in resolving time zone offsets as Gregorian calendar introduced since Java 8.
### Does this PR introduce any user-facing change?
Yes, this PR can introduce behavior changes for dates after `1582-10-15`, in particular conversions of zone ids to zone offsets will be much more accurate.
### How was this patch tested?
By existing test suites `DateTimeUtilsSuite`, `DateFunctionsSuite`, `DateExpressionsSuite`, `CollectionExpressionsSuite`, `HiveOrcHadoopFsRelationSuite`, `ParquetIOSuite`.

### What changes were proposed in this pull request?
Hive 2.3+ supports `getTablesByType` API, which will provide an efficient way to get HiveTable with specific type. Now, we have following mappings when using `HiveExternalCatalog`.
```
CatalogTableType.EXTERNAL => HiveTableType.EXTERNAL_TABLE
CatalogTableType.MANAGED => HiveTableType.MANAGED_TABLE
CatalogTableType.VIEW => HiveTableType.VIRTUAL_VIEW
```
Without this API, we need to achieve the goal by `getTables` + `getTablesByName` + `filter with type`.
This PR add `getTablesByType` in `HiveShim`. For those hive versions don't support this API, `UnsupportedOperationException` will be thrown. And the upper logic should catch the exception and fallback to the filter solution mentioned above.
Since the JDK11 related fix in `Hive` is not released yet, manual tests against hive 2.3.7-SNAPSHOT is done by following the instructions of SPARK-29245.
### Why are the changes needed?
This API will provide better usability and performance if we want to get a list of hiveTables with specific type. For example `HiveTableType.VIRTUAL_VIEW` corresponding to `CatalogTableType.VIEW`.
### Does this PR introduce any user-facing change?
No, this is a support function.
### How was this patch tested?
Add tests in VersionsSuite and manually run JDK11 test with following settings:
- Hive 2.3.6 Metastore on JDK8
- Hive 2.3.7-SNAPSHOT library build from source of Hive 2.3 branch
- Spark build with Hive 2.3.7-SNAPSHOT on jdk-11.0.6

### What changes were proposed in this pull request?
In the PR, I propose to correct and re-use functions from `DateTimeUtils` for rebasing days before the cutover day `1582-10-15` in `org.apache.spark.sql.hive.DaysWritable`.
### Why are the changes needed?
0. Existing rebasing of days in `DaysWritable` is not correct.
1. To deduplicate code in `DaysWritable`
2. To use functions that are better tested and cross checked by loading dates/timestamps from Parquet/Avro files written by Spark 2.4.5
### Does this PR introduce any user-facing change?
This PR can introduce behavior change because the replaced code is different from the re-used code from `DateTimeUtils`.
### How was this patch tested?
By existing test suite, for instance `HiveOrcHadoopFsRelationSuite`.

### What changes were proposed in this pull request?
A few `CREATE TABLE` test cases have some assumption on the default value of `LEGACY_CREATE_HIVE_TABLE_BY_DEFAULT_ENABLED`. This PR (SPARK-31181) makes the test cases more explicit from test-case side.
The configuration change was tested via https://github.com/apache/spark/pull/27894 during discussing SPARK-31136. This PR has only the test case part from that PR.
### Why are the changes needed?
This makes our test case more robust in terms of the default value of `LEGACY_CREATE_HIVE_TABLE_BY_DEFAULT_ENABLED`. Even in the case where we switch the conf value, that will be one-liner with no test case changes.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Pass the Jenkins with the existing tests.

### What changes were proposed in this pull request?
In Spark CLI, we create a hive `CliSessionState` and it does not load the `hive-site.xml`. So the configurations in `hive-site.xml` will not take effects like other spark-hive integration apps.
Also, the warehouse directory is not correctly picked. If the `default` database does not exist, the `CliSessionState` will create one during the first time it talks to the metastore. The `Location` of the default DB will be neither the value of `spark.sql.warehousr.dir` nor the user-specified value of `hive.metastore.warehourse.dir`, but the default value of `hive.metastore.warehourse.dir `which will always be `/user/hive/warehouse`.
### Why are the changes needed?
fix bug for Spark SQL cli to pick right confs
### Does this PR introduce any user-facing change?
yes, the non-exists default database will be created in the location specified by the users via `spark.sql.warehouse.dir` or `hive.metastore.warehouse.dir`, or the default value of `spark.sql.warehouse.dir` if none of them specified.
### How was this patch tested?

### What changes were proposed in this pull request?
As a common usage and according to the spark doc, users may often just copy their `hive-site.xml` to Spark directly from hive projects. Sometimes, the config file is not that clean for spark and may cause some side effects.
for example, `hive.session.history.enabled` will create a log for the hive jobs but useless for spark and also it will not be deleted on JVM exit.
this pr
1) disable `hive.session.history.enabled` explicitly to disable creating `hive_job_log` file, e.g.
```
Hive history file=/var/folders/01/h81cs4sn3dq2dd_k4j6fhrmc0000gn/T//kentyao/hive_job_log_79c63b29-95a4-4935-a9eb-2d89844dfe4f_493861201.txt
```
2) set `hive.execution.engine` to `spark` explicitly in case the config is `tez` and casue uneccesary problem like this:
```
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tez/dag/api/SessionNotRunning
at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:529)
```
### Why are the changes needed?
reduce overhead of internal complexity and users' hive cognitive load for running spark
### Does this PR introduce any user-facing change?
yes, `hive_job_log` file will not be created even enabled, and will not try to initialize tez kinds of stuff
### How was this patch tested?
add ut and verify manually

### What changes were proposed in this pull request?
In the PR, I propose to change conversion of java.sql.Timestamp/Date values to/from internal values of Catalyst's TimestampType/DateType before cutover day `1582-10-15` of Gregorian calendar. I propose to construct local date-time from microseconds/days since the epoch. Take each date-time component `year`, `month`, `day`, `hour`, `minute`, `second` and `second fraction`, and construct java.sql.Timestamp/Date using the extracted components.
### Why are the changes needed?
This will rebase underlying time/date offset in the way that collected java.sql.Timestamp/Date values will have the same local time-date component as the original values in Gregorian calendar.
Here is the example which demonstrates the issue:
```sql
scala> sql("select date '1100-10-10'").collect()
res1: Array[org.apache.spark.sql.Row] = Array([1100-10-03])
```
### Does this PR introduce any user-facing change?
Yes, after the changes:
```sql
scala> sql("select date '1100-10-10'").collect()
res0: Array[org.apache.spark.sql.Row] = Array([1100-10-10])
```
### How was this patch tested?
By running `DateTimeUtilsSuite`, `DateFunctionsSuite` and `DateExpressionsSuite`.

This PR adds functionality to HiveExternalCatalog to be able to change the provider of a table.
This is useful for catalogs in Spark 3.0 to be able to use alterTable to change the provider of a table as part of an atomic REPLACE TABLE function.
