### What changes were proposed in this pull request?
This patch removes v1 ALTER TABLE CHANGE COLUMN syntax.
### Why are the changes needed?
Since in v2 we have ALTER TABLE CHANGE COLUMN and ALTER TABLE RENAME COLUMN, this old syntax is not necessary now and can be confusing.
The v2 ALTER TABLE CHANGE COLUMN should fallback to v1 AlterTableChangeColumnCommand (#26354).
### Does this PR introduce any user-facing change?
Yes, the old v1 ALTER TABLE CHANGE COLUMN syntax is removed.

### What changes were proposed in this pull request?
Added new expressions `MultiplyInterval` and `DivideInterval` to multiply/divide an interval by a numeric. Updated `TypeCoercion.DateTimeOperations` to turn the `Multiply`/`Divide` expressions of `CalendarIntervalType` and `NumericType` to `MultiplyInterval`/`DivideInterval`.
To support new operations, added new methods `multiply()` and `divide()` to `CalendarInterval`.
### Why are the changes needed?
- To maintain feature parity with PostgreSQL which supports multiplication and division of intervals by doubles:
```sql
# select interval '1 hour' / double precision '1.5';
?column?
----------
00:40:00
```
- To conform the SQL standard which defines those operations: `numeric * interval`, `interval * numeric` and `interval / numeric`. See [4.5.3 Operations involving datetimes and intervals](http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt).
- Improve Spark SQL UX and allow users to adjust interval columns. For example:
```sql
spark-sql> select (timestamp'now' - timestamp'yesterday') * 1.3;
interval 2 days 10 hours 39 minutes 38 seconds 568 milliseconds 900 microseconds
```
### Does this PR introduce any user-facing change?
Yes, previously the following query fails with the error:
```sql
spark-sql> select interval 1 hour 30 minutes * 1.5;
Error in query: cannot resolve '(interval 1 hours 30 minutes * 1.5BD)' due to data type mismatch: differing types in '(interval 1 hours 30 minutes * 1.5BD)' (interval and decimal(2,1)).; line 1 pos 7;
```
After:
```sql
spark-sql> select interval 1 hour 30 minutes * 1.5;
interval 2 hours 15 minutes
```
### How was this patch tested?
- Added tests for the `multiply()` and `divide()` methods to `CalendarIntervalSuite.java`
- New test suite `IntervalExpressionsSuite`
- by tests for `Multiply` -> `MultiplyInterval` and `Divide` -> `DivideInterval` in `TypeCoercionSuite`
- updated `datetime.sql`

### What changes were proposed in this pull request?
Add AlterTableSerDePropertiesStatement and make ALTER TABLE ... SET SERDE/SERDEPROPERTIES go through the same catalog/table resolution framework of v2 commands.
### Why are the changes needed?
It's important to make all the commands have the same table resolution behavior, to avoid confusing end-users. e.g.
```
USE my_catalog
DESC t // success and describe the table t from my_catalog
ALTER TABLE t SET SERDE 'org.apache.class' // report table not found as there is no table t in the session catalog
```
### Does this PR introduce any user-facing change?
Yes. When running ALTER TABLE ... SET SERDE/SERDEPROPERTIES, Spark fails the command if the current catalog is set to a v2 catalog, or the table name specified a v2 catalog.

### What changes were proposed in this pull request?
Disallow creating a permanent view that references a temporary view in **expressions**.
### Why are the changes needed?
Creating a permanent view that references a temporary view is currently disallowed. For example,
```SQL
# The following throws org.apache.spark.sql.AnalysisException
# Not allowed to create a permanent view `per_view` by referencing a temporary view `tmp`;
CREATE VIEW per_view AS SELECT t1.a, t2.b FROM base_table t1, (SELECT * FROM tmp) t2"
```
However, the following is allowed.
```SQL
CREATE VIEW per_view AS SELECT * FROM base_table WHERE EXISTS (SELECT * FROM tmp);
```
This PR fixes the bug where temporary views used inside expressions are not checked.
### Does this PR introduce any user-facing change?
Yes. Now the following SQL query throws an exception as expected:
```SQL
# The following throws org.apache.spark.sql.AnalysisException
# Not allowed to create a permanent view `per_view` by referencing a temporary view `tmp`;
CREATE VIEW per_view AS SELECT * FROM base_table WHERE EXISTS (SELECT * FROM tmp);

## What changes were proposed in this pull request?
This patch adds the option to clean up files which are completed in previous batch.
`cleanSource` -> "archive" / "delete" / "off"
The default value is "off", which Spark will do nothing.
If "delete" is specified, Spark will simply delete input files. If "archive" is specified, Spark will require additional config `sourceArchiveDir` which will be used to move input files to there. When archiving (via move) the path of input files are retained to the archived paths as sub-path.
Note that it is only applied to "micro-batch", since for batch all input files must be kept to get same result across multiple query executions.
## How was this patch tested?
Added UT. Manual test against local disk as well as HDFS.

This pr proposes to be case insensitive when matching dialects via jdbc url prefix.
When I use jdbc url such as: ```jdbc: MySQL://localhost/db``` to query data through sparksql, the result is wrong, but MySQL supports such url writing.
because sparksql matches MySQLDialect by prefix ```jdbc:mysql```, so ```jdbc: MySQL``` is not matched with the correct dialect. Therefore, it should be case insensitive when identifying the corresponding dialect through jdbc url

### What changes were proposed in this pull request?
Currently, JDBC/ODBC tab in the WEBUI doesn't support hiding table. Other tabs in the web ui like, Jobs, stages, SQL etc supports hiding table (refer https://github.com/apache/spark/pull/22592).
In this PR, added the support for hide table in the jdbc/odbc tab also.
### Why are the changes needed?
Spark ui about the contents of the form need to have hidden and show features, when the table records very much. Because sometimes you do not care about the record of the table, you just want to see the contents of the next table, but you have to scroll the scroll bar for a long time to see the contents of the next table.

### What changes were proposed in this pull request?
- Retry the tests for special date-time values on failure. The tests can potentially fail when reference values were taken before midnight and test code resolves special values after midnight. The retry can guarantees that the tests run during the same day.
- Simplify getting of the current timestamp via `Instant.now()`. This should avoid any issues of converting current local datetime to an instance. For example, the same local time can be mapped to 2 instants when clocks are turned backward 1 hour on daylight saving date.
- Extract common code to SQLHelper

### What changes were proposed in this pull request?
This is somewhat a complement of https://github.com/apache/spark/pull/21853.
The `Sort` without `Limit` operator in `Join` subquery is useless, it's the same case in `GroupBy` when the aggregation function is order irrelevant, such as `count`, `sum`.
This PR try to remove this kind of `Sort` operator in `SQL Optimizer`.
### Why are the changes needed?
For example, `select count(1) from (select a from test1 order by a)` is equal to `select count(1) from (select a from test1)`.
'select * from (select a from test1 order by a) t1 join (select b from test2) t2 on t1.a = t2.b' is equal to `select * from (select a from test1) t1 join (select b from test2) t2 on t1.a = t2.b`.
Remove useless `Sort` operator can improve performance.

### What changes were proposed in this pull request?
The `assertEquals` method of JUnit Assert requires the first parameter to be the expected value. In this PR, I propose to change the order of parameters when the expected value is passed as the second parameter.
### Why are the changes needed?
Wrong order of assert parameters confuses when the assert fails and the parameters have special string representation. For example:
```java
assertEquals(input1.add(input2), new CalendarInterval(5, 5, 367200000000L));
```
```
java.lang.AssertionError:

### What changes were proposed in this pull request?
This adds a new rule, `V2ScanRelationPushDown`, to push filters and projections in to a new `DataSourceV2ScanRelation` in the optimizer. That scan is then used when converting to a physical scan node. The new relation correctly reports stats based on the scan.
To run scan pushdown before rules where stats are used, this adds a new optimizer override, `earlyScanPushDownRules` and a batch for early pushdown in the optimizer, before cost-based join reordering. The other early pushdown rule, `PruneFileSourcePartitions`, is moved into the early pushdown rule set.
This also moves pushdown helper methods from `DataSourceV2Strategy` into a util class.
### Why are the changes needed?
This is needed for DSv2 sources to supply stats for cost-based rules in the optimizer.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
In the PR, I propose to extract parsing of the seconds interval units to the private method `parseNanos` in `IntervalUtils` and modify the code to correctly parse the fractional part of the seconds unit of intervals in the cases:

- The seconds unit is negative
### Why are the changes needed?
The changes are needed to fix the issues:
```sql
spark-sql> select interval '10.123456 seconds';
interval 10 seconds 123 microseconds
```
The correct result must be `interval 10 seconds 123 milliseconds 456 microseconds`
```sql
spark-sql> select interval '-10.123456789 seconds';
interval -9 seconds -876 milliseconds -544 microseconds
```
but the whole interval should be negated, and the result must be `interval -10 seconds -123 milliseconds -456 microseconds`, taking into account the truncation to microseconds.
### Does this PR introduce any user-facing change?
Yes. After changes:
```sql
spark-sql> select interval '10.123456 seconds';
interval 10 seconds 123 milliseconds 456 microseconds
spark-sql> select interval '-10.123456789 seconds';
interval -10 seconds -123 milliseconds -456 microseconds
```
### How was this patch tested?
By existing and new tests in `ExpressionParserSuite`.

### What changes were proposed in this pull request?
This adds a new rule, `V2ScanRelationPushDown`, to push filters and projections in to a new `DataSourceV2ScanRelation` in the optimizer. That scan is then used when converting to a physical scan node. The new relation correctly reports stats based on the scan.
To run scan pushdown before rules where stats are used, this adds a new optimizer override, `earlyScanPushDownRules` and a batch for early pushdown in the optimizer, before cost-based join reordering. The other early pushdown rule, `PruneFileSourcePartitions`, is moved into the early pushdown rule set.
This also moves pushdown helper methods from `DataSourceV2Strategy` into a util class.
### Why are the changes needed?
This is needed for DSv2 sources to supply stats for cost-based rules in the optimizer.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
This updates the implementation of stats from `DataSourceV2Relation` so tests will fail if stats are accessed before early pushdown for v2 relations.

### What changes were proposed in this pull request?
To push the built jars to maven release repository, we need to remove the 'SNAPSHOT' tag from the version name.
Made the following changes in this PR:
* Update all the `3.0.0-SNAPSHOT` version name to `3.0.0-preview`
* Update the sparkR version number check logic to allow jvm version like `3.0.0-preview`
**Please note those changes were generated by the release script in the past, but this time since we manually add tags on master branch, we need to manually apply those changes too.**
We shall revert the changes after 3.0.0-preview release passed.
### Why are the changes needed?
To make the maven release repository to accept the built jars.

Closes#26321 from yaooqinn/SPARK-29653.
Authored-by: Kent Yao <yaooqinn@hotmail.com>
Signed-off-by: Dongjoon Hyun <dhyun@apple.com>
### What changes were proposed in this pull request?
This patch fixes the issue that external listeners are not initialized properly when `spark.sql.hive.metastore.jars` is set to either "maven" or custom list of jar.
("builtin" is not a case here - all jars in Spark classloader are also available in separate classloader)
The culprit is lazy initialization (lazy val or passing builder function) & thread context classloader. HiveClient leverages IsolatedClientLoader to properly load Hive and relevant libraries without issue - to not mess up with Spark classpath it uses separate classloader with leveraging thread context classloader.
But there's a messed-up case - SessionState is being initialized while HiveClient changed the thread context classloader from Spark classloader to Hive isolated one, and streaming query listeners are loaded from changed classloader while initializing SessionState.
This patch forces initializing SessionState in SparkSQLEnv to avoid such case.
### Why are the changes needed?
ClassNotFoundException could occur in spark-sql with specific configuration, as explained above.
### Does this PR introduce any user-facing change?
No, as I don't think end users assume the classloader of external listeners is only containing jars for Hive client.
### How was this patch tested?
New UT added which fails on master branch and passes with the patch.
The error message with master branch when running UT:

## What changes were proposed in this pull request?
Now, `RepartitionByExpression` is allowed at Dataset method `Dataset.repartition()`. But in spark sql, we do not have an equivalent functionality.
In hive, we can use `distribute by`, so it's worth to add a hint to support such function.
Similar jira [SPARK-24940](https://issues.apache.org/jira/browse/SPARK-24940)
## Why are the changes needed?
Make repartition hints consistent with repartition api .
## Does this PR introduce any user-facing change?
This pr intends to support quries below;
```
// SQL cases
- sql("SELECT /*+ REPARTITION(c) */ * FROM t")
- sql("SELECT /*+ REPARTITION(1, c) */ * FROM t")
- sql("SELECT /*+ REPARTITION_BY_RANGE(c) */ * FROM t")

### What changes were proposed in this pull request?
In the PR, I propose to move all static methods from the `CalendarInterval` class to the `IntervalUtils` object. All those methods are rewritten from Java to Scala.
### Why are the changes needed?
- For consistency with other helper methods. Such methods were placed to the helper object `IntervalUtils`, see https://github.com/apache/spark/pull/26190
- Taking into account that `CalendarInterval` will be fully exposed to users in the future (see https://github.com/apache/spark/pull/25022), it would be nice to clean it up by moving service methods to an internal object.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
- By moved tests from `CalendarIntervalSuite` to `IntervalUtilsSuite`
- By existing test suites

### What changes were proposed in this pull request?
Add AlterTableRecoverPartitionsStatement and make ALTER TABLE ... RECOVER PARTITIONS go through the same catalog/table resolution framework of v2 commands.
### Why are the changes needed?
It's important to make all the commands have the same table resolution behavior, to avoid confusing end-users. e.g.
```
USE my_catalog
DESC t // success and describe the table t from my_catalog
ALTER TABLE t RECOVER PARTITIONS // report table not found as there is no table t in the session catalog
```
### Does this PR introduce any user-facing change?
Yes. When running ALTER TABLE ... RECOVER PARTITIONS Spark fails the command if the current catalog is set to a v2 catalog, or the table name specified a v2 catalog.
### How was this patch tested?
Unit tests.
