Set the list of read columns in the task configuration to reduce reading of ORC data.
### Why are the changes needed?
Now, the ORC reader will read all columns of the ORC table when the task configuration does not set the list of read columns . Therefore, we should set the list of read columns in the task configuration to reduce reading of ORC data.

### What changes were proposed in this pull request?
Remove the usage of the enumerating subclasses of `StateStoreCustomMetric` dependency.
To achieve it, add couple of utility methods to `StateStoreCustomMetric`
* `withNewDesc(desc : String)` to `StateStoreCustomMetric` for cloning the instance with a new `desc` (currently used in `SymmetricHashJoinStateManager`)
* `createSQLMetric(sparkContext: sparkContext): SQLMetric` for creating a corresponding `SQLMetric` to show the metric in UI and accumulate at the query level (currently used in `statefulOperator. stateStoreCustomMetrics`)
### Why are the changes needed?
Code in [SymmetricHashJoinStateManager](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/state/SymmetricHashJoinStateManager.scala#L321) and [StateStoreWriter](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/statefulOperators.scala#L129) rely on the subclass implementations of [StateStoreCustomMetric](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/state/StateStore.scala#L187).
If a new subclass of `StateStoreCustomMetric` is added, it requires code changes to `SymmetricHashJoinStateManager` and `StateStoreWriter`, and we may miss the update if there is no existing test coverage.
To prevent these issues add a couple of utility methods to `StateStoreCustomMetric` as mentioned above.

### What changes were proposed in this pull request?
Currently, `ResolveAggregateFunctions` is a complicated rule that recursively calls the entire analyzer to resolve aggregate functions in parent nodes of aggregate. It's kind of necessary as we need to do many things to identify the aggregate function and push it down to the aggregate node: resolve columns as if they are in the aggregate node, resolve functions, apply type coercion, etc. However, this is overly complicated and it's hard to fully understand how the resolution is done there. It also leads to hacks such as the [char/varchar hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2396-L2401), [subquery hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2274-L2277), [grouping function hack](https://github.com/apache/spark/blob/v3.1.2/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala#L2465-L2467), etc.
This PR simplifies the `ResolveAggregateFunctions` rule and clarifies the resolution logic. To resolve aggregate functions/grouping columns in HAVING, ORDER BY and `df.where`, we expand the aggregate node below to output these required aggregate functions/grouping columns. In details, when resolving an expression from the parent of an aggregate node:
1. try to resolve columns with `agg.child` and wrap the result with `TempResolvedColumn`.
2. try to resolve subqueries with `agg.child`
3. if the expression is not resolved, return it and wait for other rules to resolve it, such as resolve functions, type coercions, etc.
4. if the expression is resolved, we transform it and push aggregate functions/grouping columns into the aggregate node below.
4.1 the expression may already present in `agg.aggregateExpressions`, we can simply replace the expression with attr ref.
4.2 if a `TempResolvedColumn` is neither inside an aggregate function, or wrap a grouping column, turn it back to an `UnresolvedAttribute`
5. after the main resolution batch, remove all `TempResolvedColumn` and turn them back to `UnresolvedAttribute`.

### What changes were proposed in this pull request?
Cache commonly occurring duplicate Some objects in SQLMetrics by using a Guava cache and reusing the existing Guava String Interner to avoid duplicate strings in JSONProtocol. Also with AccumulatorV2 we have seen lot of Some(-1L) and Some(0L) occurrences in a heap dump that is naively interned by having reusing a already constructed Some(-1L) and Some(0L)
To give some context on the impact and the garbage got accumulated, below are the details of the complex spark job which we troubleshooted and figured out the bottlenecks. **tl;dr - In short, major issues were the accumulation of duplicate objects mainly from SQLMetrics.**
Greater than 25% of the 40G driver heap filled with (a very large number of) **duplicate**, immutable objects.
1. Very large number of **duplicate** immutable objects.
- Type of metric is represented by `'scala.Some("sql")'` - which is created for each metric.
- Fixing this reduced memory usage from 4GB to a few bytes.
2. `scala.Some(0)` and `scala.Some(-1)` are very common metric values (typically to indicate absence of metric)
- Individually the values are all immutable, but spark sql was creating a new instance each time.
- Intern'ing these resulted in saving ~4.5GB for a 40G heap.
3. Using string interpolation for metric names.
- Interpolation results in creation of a new string object.
- We end up with a very large number of metric names - though the number of unique strings is miniscule.
- ~7.5 GB in the 40 GB heap : which went down to a few KB's when fixed.
### Why are the changes needed?
To reduce overall driver memory footprint which eventually reduces the Full GC pauses.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Since these are memory related optimizations, unit tests are not added. These changes are added in our internal platform which made it possible for one of the complex spark job continuously failing to succeed along with other set of optimizations.

This is a followup of https://github.com/apache/spark/pull/31964
We should only quote the column name when nested column predicate pushdown is enabled, otherwise the data source side may not have the logic to parse the quoted column name and fail. This is not a problem before #31964 , as we don't quote the column name if there is no dot in the name. But #31964 changed it.

### What changes were proposed in this pull request?
This is to fix the maximal allowed number of rows check in `BroadcastExchangeExec`. After https://github.com/apache/spark/pull/27828, the max number of rows is calculated based on max capacity of `BytesToBytesMap` (previous value before the PR is 512000000). This calculation is not accurate as only `UnsafeHashedRelation` is using `BytesToBytesMap`. `LongHashedRelation` (used for broadcast join on key with long data type) has limit of [512000000](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/joins/HashedRelation.scala#L584), and `BroadcastNestedLoopJoinExec` is not depending on `HashedRelation` at all.
The change is to only specialize the max rows limit when needed. Keep other broadcast case with the previous limit - 512000000.

### What changes were proposed in this pull request?
Remove commons-httpclient as a direct dependency for Hadoop-3.2 profile.
Hadoop-2.7 profile distribution still has it, hadoop-client has a compile dependency on commons-httpclient, thus we cannot remove it for Hadoop-2.7 profile.

### What changes were proposed in this pull request?
Extend `YearMonthIntervalType` to support interval fields. Valid interval field values:
- 0 (YEAR)
- 1 (MONTH)
After the changes, the following year-month interval types are supported:
1. `YearMonthIntervalType(0, 0)` or `YearMonthIntervalType(YEAR, YEAR)`
2. `YearMonthIntervalType(0, 1)` or `YearMonthIntervalType(YEAR, MONTH)`. **It is the default one**.
3. `YearMonthIntervalType(1, 1)` or `YearMonthIntervalType(MONTH, MONTH)`
Closes#32825
### Why are the changes needed?
In the current implementation, Spark supports only `interval year to month` but the SQL standard allows to specify the start and end fields. The changes will allow to follow ANSI SQL standard more precisely.
### Does this PR introduce _any_ user-facing change?
Yes but `YearMonthIntervalType` has not been released yet.

`CoalesceExec` needlessly calls `child.execute` twice when it could just call it once and re-use the results. This only happens when `numPartitions == 1`.
### Why are the changes needed?
It is more efficient to execute the child plan once rather than twice.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
There are no functional changes. This is just a performance optimization, so the existing tests should be sufficient to catch any regressions.

### What changes were proposed in this pull request?
Currently, the file CastSuite.scala becomes big: 2000 lines, 2 base classes, 4 test suites.
In my previous work of Timestamp without time zone, I planned to put new test cases in CastSuiteBase, but they were accidentally added in AnsiCastSuiteBase.
This PR is to break the file down into 3 files. It also moves the test cases about timestamp without time zone to the right base class.

### What changes were proposed in this pull request?
This PR updates the document about building Spark with Hadoop for Hadoop 3.x and Hadoop 3.2.
### Why are the changes needed?
The document says about how to build like as follows:
```
./build/mvn -Pyarn -Dhadoop.version=2.8.5 -DskipTests clean package
```
But this command fails because the default build settings are for Hadoop 3.x.
So, we need to modify the command example.

No.
### How was this patch tested?
I confirmed both of these commands successfully finished.

### What changes were proposed in this pull request?
This PR fix the wrong behavior of `Index.difference` in pandas APIs on Spark, based on the comment https://github.com/databricks/koalas/pull/1325#discussion_r647889901 and https://github.com/databricks/koalas/pull/1325#discussion_r647890007
- it couldn't handle the case properly when `self` is `Index` or `MultiIndex` and `other` is `MultiIndex` or `Index`.
```python
>>> midx1 = ps.MultiIndex.from_tuples([('a', 'x', 1), ('b', 'z', 2), ('k', 'z', 3)])
>>> idx1 = ps.Index([1, 2, 3])
>>> midx1 = ps.MultiIndex.from_tuples([('a', 'x', 1), ('b', 'z', 2), ('k', 'z', 3)])
>>> midx1.difference(idx1)
pyspark.pandas.exceptions.PandasNotImplementedError: The method `pd.Index.__iter__()` is not implemented. If you want to collect your data as an NumPy array, use 'to_numpy()' instead.
```
- it's collecting the all data into the driver side when the other is list-like objects, especially when the `other` is distributed object such as Series which is very dangerous.
And added the related test cases.
### Why are the changes needed?
To correct the incompatible behavior with pandas, and to prevent the case which potentially cause the OOM easily.
```python
>>> midx1 = ps.MultiIndex.from_tuples([('a', 'x', 1), ('b', 'z', 2), ('k', 'z', 3)])
>>> idx1 = ps.Index([1, 2, 3])
>>> midx1 = ps.MultiIndex.from_tuples([('a', 'x', 1), ('b', 'z', 2), ('k', 'z', 3)])
>>> midx1.difference(idx1)
MultiIndex([('a', 'x', 1),
('b', 'z', 2),
('k', 'z', 3)],
)
```
And now it only using the for loop when the `other` is only the case `list`, `set` or `dict`.

### What changes were proposed in this pull request?
Make `astype` method data-type-based.
**Non-goal: Match pandas' `astype` TypeErrors.**
Currently, `astype` throws TypeError error messages only when the destination type is not recognized. However, for some destination types that don't make sense to the specific type of Series/Index, for example, `numeric Series/Index → bytes`, we don't have proper TypeError error messages.
Since the goal of the PR is refactoring mainly, the above issue might be resolved later if needed.
### Why are the changes needed?
There are many type checks in the `astype` method. Since `DataTypeOps` and its subclasses are introduced, we should refactor `astype` to make it data-type-based. In this way, code is cleaner, more maintainable, and more flexible.

### What changes were proposed in this pull request?
This is a followup PR for SPARK-35736(#32893) and SPARK-35737(#32892).
This PR moves a common logic to `object DayTimeIntervalType`.
That logic is like `val strToFieldIndex = DayTimeIntervalType.dayTimeFields.map(i => DayTimeIntervalType.fieldToString(i) -> (i).toMap`, a `Map` which maps each time unit to the corresponding day-time field index.

Bug fix for deadlock during the executor shutdown
### Why are the changes needed?
When a executor received a TERM signal, it (the second TERM signal) will lock java.lang.Shutdown class and then call Shutdown.exit() method to exit the JVM.
Shutdown will call SparkShutdownHook to shutdown the executor.
During the executor shutdown phase, RemoteProcessDisconnected event will be send to the RPC inbox, and then WorkerWatcher will try to call System.exit(-1) again.
Because java.lang.Shutdown has already locked, a deadlock has occurred.

### What changes were proposed in this pull request?
Instantiate a new Hive client through `Hive.getWithoutRegisterFns(conf, false)` instead of `Hive.get(conf)`, if `Hive` version is >= '2.3.9' (the built-in version).
### Why are the changes needed?
[HIVE-10319](https://issues.apache.org/jira/browse/HIVE-10319) introduced a new API `get_all_functions` which is only supported in Hive 1.3.0/2.0.0 and up. As result, when Spark 3.x talks to a HMS service of version 1.2 or lower, the following error will occur:
```
Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: org.apache.thrift.TApplicationException: Invalid method name: 'get_all_functions'
at org.apache.hadoop.hive.ql.metadata.Hive.getAllFunctions(Hive.java:3897)
at org.apache.hadoop.hive.ql.metadata.Hive.reloadFunctions(Hive.java:248)
at org.apache.hadoop.hive.ql.metadata.Hive.registerAllFunctionsOnce(Hive.java:231)
... 96 more
Caused by: org.apache.thrift.TApplicationException: Invalid method name: 'get_all_functions'
at org.apache.thrift.TServiceClient.receiveBase(TServiceClient.java:79)
at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.recv_get_all_functions(ThriftHiveMetastore.java:3845)
at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.get_all_functions(ThriftHiveMetastore.java:3833)
```
The `get_all_functions` is called only when `doRegisterAllFns` is set to true:
```java
private Hive(HiveConf c, boolean doRegisterAllFns) throws HiveException {
conf = c;
if (doRegisterAllFns) {
registerAllFunctionsOnce();
}
}
```
what this does is to register all Hive permanent functions defined in HMS in Hive's `FunctionRegistry` class, via iterating through results from `get_all_functions`. To Spark, this seems unnecessary as it loads Hive permanent (not built-in) UDF via directly calling the HMS API, i.e., `get_function`. The `FunctionRegistry` is only used in loading Hive's built-in function that is not supported by Spark. At this time, it only applies to `histogram_numeric`.
[HIVE-21563](https://issues.apache.org/jira/browse/HIVE-21563) introduced a new API `getWithoutRegisterFns` which skips the above registration and is available in Hive 2.3.9. Therefore, Spark should adopt it to avoid the cost.
### Does this PR introduce _any_ user-facing change?
Yes with this fix Spark now should be able to talk to HMS server with Hive 1.2.x and lower.
### How was this patch tested?
Manually started a HMS server of Hive version 1.2.2. Without the PR it failed with the above exception. With the PR the error disappeared and I can successfully perform common operations such as create table, create database, list tables, etc.

### What changes were proposed in this pull request?
Extend DayTimeIntervalType to support interval fields. Valid interval field values:
- 0 (DAY)
- 1 (HOUR)
- 2 (MINUTE)
- 3 (SECOND)
After the changes, the following day-time interval types are supported:
1. `DayTimeIntervalType(0, 0)` or `DayTimeIntervalType(DAY, DAY)`
2. `DayTimeIntervalType(0, 1)` or `DayTimeIntervalType(DAY, HOUR)`
3. `DayTimeIntervalType(0, 2)` or `DayTimeIntervalType(DAY, MINUTE)`
4. `DayTimeIntervalType(0, 3)` or `DayTimeIntervalType(DAY, SECOND)`. **It is the default one**. The second fraction precision is microseconds.
5. `DayTimeIntervalType(1, 1)` or `DayTimeIntervalType(HOUR, HOUR)`
6. `DayTimeIntervalType(1, 2)` or `DayTimeIntervalType(HOUR, MINUTE)`
7. `DayTimeIntervalType(1, 3)` or `DayTimeIntervalType(HOUR, SECOND)`
8. `DayTimeIntervalType(2, 2)` or `DayTimeIntervalType(MINUTE, MINUTE)`
9. `DayTimeIntervalType(2, 3)` or `DayTimeIntervalType(MINUTE, SECOND)`
10. `DayTimeIntervalType(3, 3)` or `DayTimeIntervalType(SECOND, SECOND)`
### Why are the changes needed?
In the current implementation, Spark supports only `interval day to second` but the SQL standard allows to specify the start and end fields. The changes will allow to follow ANSI SQL standard more precisely.

Yes but `DayTimeIntervalType` has not been released yet.
### How was this patch tested?
By existing test suites.
Closes#32849 from MaxGekk/day-time-interval-type-units.

STRUCT(fieldNmae: fileType [NOT NULL][COMMENT stringLiteral][,.....])
So the field list is nearly the same as a column list
if we could make ':' optional it would be so much cleaner an less proprietary
