### What changes were proposed in this pull request?
Current CalendarInterval has 2 fields: months and microseconds. This PR try to change it
to 3 fields: months, days and microseconds. This is because one logical day interval may
have different number of microseconds (daylight saving).
### Why are the changes needed?
One logical day interval may have different number of microseconds (daylight saving).
For example, in PST timezone, there will be 25 hours from 2019-11-2 12:00:00 to
2019-11-3 12:00:00

### What changes were proposed in this pull request?
Add AlterTableRenamePartitionStatement and make ALTER TABLE ... RENAME TO PARTITION 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 PARTITION (id=1) RENAME TO PARTITION (id=2) // 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 ... RENAME TO PARTITION, 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?
This PR changes the behavior of `Column.getItem` to call `Column.getItem` on Scala side instead of `Column.apply`.
### Why are the changes needed?
The current behavior is not consistent with that of Scala.
In PySpark:
```Python
df = spark.range(2)
map_col = create_map(lit(0), lit(100), lit(1), lit(200))
df.withColumn("mapped", map_col.getItem(col('id'))).show()
# +---+------+
# | id|mapped|
# +---+------+
# | 0| 100|
# | 1| 200|
# +---+------+
```
In Scala:
```Scala
val df = spark.range(2)
val map_col = map(lit(0), lit(100), lit(1), lit(200))
// The following getItem results in the following exception, which is the right behavior:
// java.lang.RuntimeException: Unsupported literal type class org.apache.spark.sql.Column id
// at org.apache.spark.sql.catalyst.expressions.Literal$.apply(literals.scala:78)
// at org.apache.spark.sql.Column.getItem(Column.scala:856)
// ... 49 elided
df.withColumn("mapped", map_col.getItem(col("id"))).show
```
### Does this PR introduce any user-facing change?
Yes. If the use wants to pass `Column` object to `getItem`, he/she now needs to use the indexing operator to achieve the previous behavior.
```Python
df = spark.range(2)
map_col = create_map(lit(0), lit(100), lit(1), lit(200))
df.withColumn("mapped", map_col[col('id'))].show()
# +---+------+
# | id|mapped|
# +---+------+
# | 0| 100|
# | 1| 200|

### What changes were proposed in this pull request?
This patch addresses CI build issue on sbt Hadoop-3.2 Jenkins job: SparkSQLEnvSuite are failing. Looks like the reason of test failure is the test checks registered listeners from active SparkSession which could be interfered with other test suites running concurrently. If we isolate test suite the problem should be gone.
### Why are the changes needed?
CI builds for "spark-master-test-sbt-hadoop-3.2" are failing.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
I've run the single test suite with below command and it passed 3 times sequentially:
```
build/sbt "hive-thriftserver/testOnly *.SparkSQLEnvSuite" -Phadoop-3.2 -Phive-thriftserver

so we expect the test suite will pass if we isolate the test suite.

### 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?
- Added `getDuration()` to calculate interval duration in specified time units assuming provided days per months
- Added `isNegative()` which return `true` is the interval duration is less than 0
- Fix checking negative intervals by using `isNegative()` in structured streaming classes
- Fix checking of `year-months` intervals
### Why are the changes needed?
This fixes incorrect checking of negative intervals. An interval is negative when its duration is negative but not if interval's months **or** microseconds is negative. Also this fixes checking of `year-month` interval support because the `month` field could be negative.

### What changes were proposed in this pull request?
Add support of `TaskContext.get()` in a barrier task from Python side, this makes it easier to migrate legacy user code to barrier execution mode.
### Why are the changes needed?
In Spark Core, there is a `TaskContext` object which is a singleton. We set a task context instance which can be TaskContext or BarrierTaskContext before the task function startup, and unset it to none after the function end. So we can both get TaskContext and BarrierTaskContext with the object. However we can only get the BarrierTaskContext with `BarrierTaskContext`, we will get `None` if we get it by `TaskContext.get` in a barrier stage.
This is useful when people switch from normal code to barrier code, and only need a little update.
### Does this PR introduce any user-facing change?
Yes.
Previously:
```python
def func(iterator):
task_context = TaskContext.get() . # this could be None.
barrier_task_context = BarrierTaskContext.get() # get the BarrierTaskContext instance
...
rdd.barrier().mapPartitions(func)
```
Proposed:
```python
def func(iterator):
task_context = TaskContext.get() . # this could also get the BarrierTaskContext instance which is same as barrier_task_context
barrier_task_context = BarrierTaskContext.get() # get the BarrierTaskContext instance
...
rdd.barrier().mapPartitions(func)

### 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:
- When the fractional part has less than 9 digits
- 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';

### 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.

### What changes were proposed in this pull request?
This PR proposes to allow `array_contains` to take column instances.
### Why are the changes needed?
For consistent support in Scala and Python APIs. Scala allows column instances at `array_contains`
Scala:
```scala
import org.apache.spark.sql.functions._
val df = Seq(Array("a", "b", "c"), Array.empty[String]).toDF("data")
df.select(array_contains($"data", lit("a"))).show()
```
Python:
```python
from pyspark.sql.functions import array_contains, lit
df = spark.createDataFrame([(["a", "b", "c"],), ([],)], ['data'])
df.select(array_contains(df.data, lit("a"))).show()
```
However, PySpark sides does not allow.
### Does this PR introduce any user-facing change?
Yes.
```python
from pyspark.sql.functions import array_contains, lit
df = spark.createDataFrame([(["a", "b", "c"],), ([],)], ['data'])
df.select(array_contains(df.data, lit("a"))).show()
```
**Before:**
```
Traceback (most recent call last):

## 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.

* Update the PySpark version from `3.0.0.dev0` to `3.0.0`
**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.

### What changes were proposed in this pull request?
There're some issues observed in `HiveUserDefinedTypeSuite."Support UDT in Hive UDF"`:
1) Neither function (TestUDF) nor test take "nullable" point column into account.
2) ExamplePointUDT. sqlType is ArrayType which doesn't provide information how many elements are expected. RandomDataGenerator may provide less elements than needed.
This patch fixes `HiveUserDefinedTypeSuite."Support UDT in Hive UDF"` to change the type of "point" column to be non-nullable, as well as not use RandomDataGenerator to create row for UDT backed by ArrayType.
