### What changes were proposed in this pull request?
Support new keyword `TIMESTAMP_LTZ`, which can be used for:
- timestamp with local time zone data type in DDL
- timestamp with local time zone data type in Cast clause.
- timestamp with local time zone data type literal
### Why are the changes needed?
Users can use `TIMESTAMP_LTZ` in DDL/Cast/Literals for the timestamp with local time zone type directly. The new keyword is independent of the SQL configuration `spark.sql.timestampType`.
### Does this PR introduce _any_ user-facing change?
No, the new timestamp type is not released yet.
### How was this patch tested?

### What changes were proposed in this pull request?
This is a followup of https://github.com/apache/spark/pull/33113, to do some code cleanup:
1. `UnresolvedFieldPosition` doesn't need to include the field name. We can get it through "context" (`AlterTableAlterColumn.column.name`).
2. Run `ResolveAlterTableCommands` in the main resolution batch, so that the column/field resolution is also unified between v1 and v2 commands (same error message).
3. Fail immediately in `ResolveAlterTableCommands` if we can't resolve the field, instead of waiting until `CheckAnalysis`. We don't expect other rules to resolve fields in ALTER TABLE commands, so failing immediately is simpler and we can remove duplicated code in `CheckAnalysis`.

### What changes were proposed in this pull request?
For the timestamp literal, it should have the following behavior.
1. When `spark.sql.timestampType` is TIMESTAMP_NTZ: if there is no time zone part, return timestamp without time zone literal; otherwise, return timestamp with local time zone literal
2. When `spark.sql.timestampType` is TIMESTAMP_LTZ: return timestamp with local time zone literal
### Why are the changes needed?
When the default timestamp type is TIMESTAMP_NTZ, the result of type literal should return TIMESTAMP_NTZ when there is no time zone part in the string.
From setion 5.3 "literal" of ANSI SQL standard 2011:
```
27) The declared type of a <timestamp literal> that does not specify <time zone interval> is TIMESTAMP(P) WITHOUT TIME ZONE, where P is the number of digits in <seconds fraction>, if specified, and 0 (zero) otherwise. The declared type of a <timestamp literal> that specifies <time zone interval> is TIMESTAMP(P) WITH TIME ZONE, where P is the number of digits in <seconds fraction>, if specified, and 0 (zero) otherwise.
```
Since we don't have "timestamp with time zone", we use timestamp with local time zone instead.
### Does this PR introduce _any_ user-facing change?
No, the new timestmap type and the default timestamp configuration is not released yet.

### What changes were proposed in this pull request?
This PR fixes an issue that `from_csv/to_csv` doesn't handle year-month intervals properly.
`from_csv` throws exception if year-month interval types are given.
```
spark-sql> select from_csv("interval '1-2' year to month", "a interval year to month");
21/07/03 04:32:24 ERROR SparkSQLDriver: Failed in [select from_csv("interval '1-2' year to month", "a interval year to month")]
java.lang.Exception: Unsupported type: interval year to month

at org.apache.spark.sql.catalyst.csv.UnivocityParser.$anonfun$valueConverters$1(UnivocityParser.scala:134)
```
Also, `to_csv` doesn't handle year-month interval types properly though any exception is thrown.
The result of `to_csv` for year-month interval types is not ANSI interval compliant form.
```
spark-sql> select to_csv(named_struct("a", interval '1-2' year to month));

```
The result above should be `INTERVAL '1-2' YEAR TO MONTH`.

Skip remove shuffle if it's shuffle origin is not `REPARTITION_BY_COL` in AQE.
### Why are the changes needed?
`REPARTITION_BY_COL` doesn't guarantee the output partitioning number so we can remove it safely in AQE.
For `REPARTITION_BY_NUM`, we should retain the shuffle which partition number is specified by user.
For `REBALANCE_PARTITIONS_BY_COL`, it is a special shuffle used to rebalance partitions so we should not remove it.

### What changes were proposed in this pull request?
Current AQE has cost evaluator to decide whether to use new plan after replanning. The current used evaluator is `SimpleCostEvaluator` to make decision based on number of shuffle in the query plan. This is not perfect cost evaluator, and different production environments might want to use different custom evaluators. E.g., sometimes we might want to still do skew join even though it might introduce extra shuffle (trade off resource for better latency), sometimes we might want to take sort into consideration for cost as well. Take our own setting as an example, we are using a custom remote shuffle service (Cosco), and the cost model is more complicated. So We want to make the cost evaluator to be pluggable, and developers can implement their own `CostEvaluator` subclass and plug in dynamically based on configuration.
The approach is to introduce a new config to allow define sub-class name of `CostEvaluator` - `spark.sql.adaptive.customCostEvaluatorClass`. And add `CostEvaluator.instantiate` to instantiate the cost evaluator class in `AdaptiveSparkPlanExec.costEvaluator`.
### Why are the changes needed?
Make AQE cost evaluation more flexible.
### Does this PR introduce _any_ user-facing change?
No but an internal config is introduced - `spark.sql.adaptive.customCostEvaluatorClass` to allow custom implementation of `CostEvaluator`.
### How was this patch tested?
Added unit test in `AdaptiveQueryExecSuite.scala`.

### What changes were proposed in this pull request?
This PR fixes two issues. One is that `to_json` doesn't support `map` types where value types are `year-month` interval types like:
```
spark-sql> select to_json(map('a', interval '1-2' year to month));
21/07/02 11:38:15 ERROR SparkSQLDriver: Failed in [select to_json(map('a', interval '1-2' year to month))]
java.lang.RuntimeException: Failed to convert value 14 (class of class java.lang.Integer) with the type of YearMonthIntervalType(0,1) to JSON.
```
The other issue is that even if the issue of `to_json` is resolved, `from_json` doesn't support to convert `year-month` interval string to JSON. So the result of following query will be `null`.
```
spark-sql> select from_json(to_json(map('a', interval '1-2' year to month)), 'a interval year to month');
{"a":null}
```
### Why are the changes needed?
There should be no reason why year-month intervals cannot used as map value types.
`CalendarIntervalTypes` can do it.
### Does this PR introduce _any_ user-facing change?
No.

### What changes were proposed in this pull request?
By default, AQE will set `COALESCE_PARTITIONS_MIN_PARTITION_NUM` to the spark default parallelism, which is usually quite big. This is to keep the parallelism on par with non-AQE, to avoid perf regressions.
However, this usually leads to many small/empty partitions, and hurts performance (although not worse than non-AQE). Users usually blindly set `COALESCE_PARTITIONS_MIN_PARTITION_NUM` to 1, which makes this config quite useless.
This PR adds a new config to set the min partition size, to avoid too small partitions after coalescing. By default, Spark will not respect the target size, and only respect this min partition size, to maximize the parallelism and avoid perf regression in AQE. This PR also adds a bool config to respect the target size when coalescing partitions, and it's recommended to set it to get better overall performance. This PR also deprecates the `COALESCE_PARTITIONS_MIN_PARTITION_NUM` config.
### Why are the changes needed?
AQE is default on now, we should make the perf better in the default case.
### Does this PR introduce _any_ user-facing change?
yes, a new config.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR implemented the proposal per [design doc](https://docs.google.com/document/d/1RfFn2e9o_1uHJ8jFGsSakp-BZMizX1uRrJSybMe2a6M) for SPARK-35779.
### Why are the changes needed?
Spark supports dynamic partition filtering that enables reusing parts of the query to skip unnecessary partitions in the larger table during joins. This optimization has proven to be beneficial for star-schema queries which are common in the industry. Unfortunately, dynamic pruning is currently limited to partition pruning during joins and is only supported for built-in v1 sources. As more and more Spark users migrate to Data Source V2, it is important to generalize dynamic filtering and expose it to all v2 connectors.
Please, see the design doc for more information on this effort.
### Does this PR introduce _any_ user-facing change?
Yes, this PR adds a new optional mix-in interface for `Scan` in Data Source V2.

unionByName does not supports struct having same col names but different sequence
```
val df1 = Seq((1, Struct1(1, 2))).toDF("a", "b")
val df2 = Seq((1, Struct2(1, 2))).toDF("a", "b")
val unionDF = df1.unionByName(df2)
```
it gives the exception
`org.apache.spark.sql.AnalysisException: Union can only be performed on tables with the compatible column types. struct<c2:int,c1:int> <> struct<c1:int,c2:int> at the second column of the second table; 'Union false, false :- LocalRelation [_1#38, _2#39] +- LocalRelation _1#45, _2#46`
In this case the col names are same so this unionByName should have the support to check within in the Struct if col names are same it should not throw this exception and works.
after fix we are getting the result
```
val unionDF = df1.unionByName(df2)

### What changes were proposed in this pull request?
If the user creates a view in 2.4 and reads it in 3.1/3.2, there will be an incompatible schema issue.
So this PR adds a view ddl in the error message to prompt the user recreating the view to fix the
incompatible issue.
For example:
```sql
-- create view in 2.4
CREATE TABLE IF NOT EXISTS t USING parquet AS SELECT '1' as a, '20210420' as b"
CREATE OR REPLACE VIEW v AS SELECT CAST(t.a AS INT), to_date(t.b, 'yyyyMMdd') FROM t
-- select view in master
SELECT * FROM v
```
Then we will get below error:
```
cannot resolve '`to_date(spark_catalog.default.t.b, 'yyyyMMdd')`' given input columns: [a, to_date(b, yyyyMMdd)];
```

### What changes were proposed in this pull request?
Rename TimestampWithoutTZType to TimestampNTZType
### Why are the changes needed?
The time name of `TimestampWithoutTZType` is verbose. Rename it as `TimestampNTZType` so that
1. it is easier to read and type.
2. As we have the function to_timestamp_ntz, this makes the names consistent.
3. We will introduce a new SQL configuration `spark.sql.timestampType` for the default timestamp type. The configuration values can be "TIMESTMAP_NTZ" or "TIMESTMAP_LTZ" for simplicity.
### Does this PR introduce _any_ user-facing change?
No, the new timestamp type is not released yet.

### What changes were proposed in this pull request?
Remove dead code in `OptimizeLocalShuffleReader`.
### Why are the changes needed?
After [SPARK-35725](https://issues.apache.org/jira/browse/SPARK-35725), we might expand partition if that partition is skewed. So the partition number check `bytesByPartitionId.length == partitionSpecs.size` would be wrong if some partitions are coalesced and some partitions are splitted into smaller.
Note that, it's unlikely happened in real world since it used RoundRobin.
Otherhand, after [SPARK-34899](https://issues.apache.org/jira/browse/SPARK-34899), we use origin plan if can not coalesce partitions. So the assuming of that shuffle stage has `CustomShuffleReaderExec` with no effect is always false in `REBALANCE_PARTITIONS_BY_NONE` shuffle origin. That said, if no rule was efficient, there would be no `CustomShuffleReaderExec`.

### What changes were proposed in this pull request?
Make the current vectorized Parquet reader to work with column index introduced in Parquet 1.11. In particular, this PR makes the following changes:
1. in `ParquetReadState`, track row ranges returned via `PageReadStore.getRowIndexes` as well as the first row index for each page via `DataPage.getFirstRowIndex`.
1. introduced a new API `ParquetVectorUpdater.skipValues` which skips a batch of values from a Parquet value reader. As part of the process also renamed existing `updateBatch` to `readValues`, and `update` to `readValue` to keep the method names consistent.
1. in correspondence as above, also introduced new API `VectorizedValuesReader.skipXXX` for different data types, as well as the implementations. These are useful when the reader knows that the given batch of values can be skipped, for instance, due to the batch is not covered in the row ranges generated by column index filtering.
2. changed `VectorizedRleValuesReader` to handle column index filtering. This is done by comparing the range that is going to be read next within the current RLE/PACKED block (let's call this block range), against the current row range. There are three cases:
* if the block range is before the current row range, skip all the values in the block range
* if the block range is after the current row range, advance the row range and repeat the steps
* if the block range overlaps with the current row range, only read the values within the overlapping area and skip the rest.
### Why are the changes needed?
[Parquet Column Index](https://github.com/apache/parquet-format/blob/master/PageIndex.md) is a new feature in Parquet 1.11 which allows very efficient filtering on page level (some benchmark numbers can be found [here](https://blog.cloudera.com/speeding-up-select-queries-with-parquet-page-indexes/)), especially when data is sorted. The feature is largely implemented in parquet-mr (via classes such as `ColumnIndex` and `ColumnIndexFilter`). In Spark, the non-vectorized Parquet reader can automatically benefit from the feature after upgrading to Parquet 1.11.x, without any code change. However, the same is not true for vectorized Parquet reader since Spark chose to implement its own logic such as reading Parquet pages, handling definition levels, reading values into columnar batches, etc.
Previously, [SPARK-26345](https://issues.apache.org/jira/browse/SPARK-26345) / (#31393) updated Spark to only scan pages filtered by column index from parquet-mr side. This is done by calling `ParquetFileReader.readNextFilteredRowGroup` and `ParquetFileReader.getFilteredRecordCount` API. The implementation, however, only work for a few limited cases: in the scenario where there are multiple columns and their type width are different (e.g., `int` and `bigint`), it could return incorrect result. For this issue, please see SPARK-34859 for a detailed description.
In order to fix the above, Spark needs to leverage the API `PageReadStore.getRowIndexes` and `DataPage.getFirstRowIndex`. The former returns the indexes of all rows (note the difference between rows and values: for flat schema there is no difference between the two, but for nested schema they're different) after filtering within a Parquet row group. The latter returns the first row index within a single data page. With the combination of the two, one is able to know which rows/values should be filtered while scanning a Parquet page.
### Does this PR introduce _any_ user-facing change?
Yes. Now the vectorized Parquet reader should work correctly with column index.
### How was this patch tested?
Borrowed tests from #31998 and added a few more tests.

### What changes were proposed in this pull request?
* Add a new rule `ExpandShufflePartitions` in AQE `queryStageOptimizerRules`
* Add a new config `spark.sql.adaptive.optimizeSkewsInRebalancePartitions.enabled` to decide if should enable the new rule
The new rule `OptimizeSkewInRebalancePartitions` only handle two shuffle origin `REBALANCE_PARTITIONS_BY_NONE` and `REBALANCE_PARTITIONS_BY_COL` for data skew issue. And re-use the exists config `ADVISORY_PARTITION_SIZE_IN_BYTES` to decide what partition size should be.
### Why are the changes needed?
Currently, we don't support expand partition dynamically in AQE which is not friendly for some data skew job.
Let's say if we have a simple query:
```
SELECT /*+ REBALANCE(col) */ * FROM table
```
The column of `col` is skewed, then some shuffle partitions would handle too much data than others.
If we haven't inroduced extra shuffle, we can optimize this case by expanding partitions in AQE.

Yes, a new config

### What changes were proposed in this pull request?
In the PR, I propose to catch all non-fatal exceptions coming `refreshTable()` at the final stage of table repairing, and output an error message instead of failing with an exception.
### Why are the changes needed?
1. The uncaught exceptions from table refreshing might be considered as regression comparing to previous Spark versions. Table refreshing was introduced by https://github.com/apache/spark/pull/31066.
2. This should improve user experience with Spark SQL. For instance, when the `MSCK REPAIR TABLE` is performed in a chain of command in SQL where catching exception is difficult or even impossible.
### Does this PR introduce _any_ user-facing change?
Yes. Before the changes the `MSCK REPAIR TABLE` command can fail with the exception portrayed in SPARK-35935. After the changes, the same command outputs error message, and completes successfully.

### What changes were proposed in this pull request?
Add a new ANSI type coercion rule: when getting a date field from a Timestamp column, cast the column as Date type.
This is Spark's current hack to make the implementation simple. In the default type coercion rules, the implicit cast rule does the work. However, The ANSI implicit cast rule doesn't allow converting Timestamp type as Date type, so we need to have this additional rule to make sure the date field extraction from Timestamp columns works.

This patch refactors the evaluation of subexpressions.
There are two changes:
1. Clean up subexpression code after evaluation to avoid duplicate evaluation.
2. Evaluate all children subexpressions when evaluating a subexpression.
### Why are the changes needed?
Currently `subexpressionEliminationForWholeStageCodegen` return the gen-ed code of subexpressions. The caller simply puts the code into its code block. We need more flexible evaluation here. For example, for Filter operator's subexpression evaluation, we may need to evaluate particular subexpression for one predicate. Current approach cannot satisfy the requirement.

Skip empty partitions in `ShufflePartitionsUtil.coalescePartitionsWithSkew`.
### Why are the changes needed?
Since [SPARK-35447](https://issues.apache.org/jira/browse/SPARK-35447), we apply `OptimizeSkewedJoin` before `CoalesceShufflePartitions`. However, There are something different with the order of these two rules.
Let's say if we have a skewed partitions: [0, 128MB, 0, 128MB, 0]:
* coalesce partitions first then optimize skewed partitions:
[64MB, 64MB, 64MB, 64MB]
* optimize skewed partition first then coalesce partitions:
[0, 64MB, 64MB, 0, 64MB, 64MB, 0]
So we can do coalesce in `ShufflePartitionsUtil.coalescePartitionsWithSkew` with mixed `CoalescedPartitionSpec` and `PartialReducerPartitionSpec` if `CoalescedPartitionSpec` is empty.

### Why are the changes needed?
As discussed in https://github.com/apache/spark/pull/33115#discussion_r659866760, it is more convenient to have a new data type "AnyTimestampType" instead of using type collection `AllTimestampTypes`:
1. simplify the pattern match
2. In the default type coercion rules, when implicit casting a type to a TypeCollection type, Spark chooses the first convertible data type as the result. If we are going to make the default timestamp type configurable, having AnyTimestampType is better

| |-- element: struct (containsNull = false)
| | |-- a1: integer (nullable = true) // OK. a1 is expected name
| | |-- b1: integer (nullable = true) // OK. b1 is expected name
df.explain
== Physical Plan ==
*(1) Project [arrays_zip(_1#3, _2#4) AS zipped#12] // Not OK. field names are re-written as _1 and _2 respectively

```
This issue happens when aliases are eliminated by `AliasHelper.replaceAliasButKeepName` or `AliasHelper.trimNonTopLevelAliases` called via analyzer/optimizer

### What changes were proposed in this pull request?
* add `dataSize` field in `CoalescedPartitionSpec`
* add data size test suite in `ShufflePartitionsUtilSuite`
### Why are the changes needed?
Currently, all test suite about `CoalescedPartitionSpec` do not check the data size due to it doesn't contains data size field.
We can add data size in `CoalescedPartitionSpec` and then add test case for better coverage.

### What changes were proposed in this pull request?
This PR fixes support for arrays and maps in `RowToColumnConverter`. In particular this PR fixes two bugs:
1. `appendArray` in `WritableColumnVector` does not reserve any elements in its child arrays, which causes the assertion in `OffHeapColumnVector.putArray` to fail.
2. The nullability of the child columns is propagated incorrectly when creating the child converters of `ArrayConverter` and `MapConverter` in `RowToColumnConverter`.
This PR fixes these issues.
### Why are the changes needed?
Both bugs cause an exception to be thrown.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
I added additional test cases to `ColumnVectorSuite` to catch the first bug, and I added `RowToColumnConverterSuite` to catch the both bugs (but specifically the second).

### What changes were proposed in this pull request?
Add a metric to track the number of duplicates dropped in input in streaming deduplication operator. Also introduce a `StatefulOperatorCustomMetric` to allow stateful operators to output their own unique metrics in `StateOperatorProgress.customMetrics` in `StreamingQueryProgress`.
### Why are the changes needed?
1. Having the duplicates dropped count help monitor and debug any incorrect results issue or find reasons for state size increases in dedupe operator.
2. New API `StatefulOperatorCustomMetric` allows stateful operators to expose their own unique metrics in `StateOperatorProgress.customMetrics` in `StreamingQueryProgress`
### Does this PR introduce _any_ user-facing change?
Yes. For deduplication stateful operator a new metric `numDuplicatesDropped` is shown in `StateOperatorProgress` within `StreamingQueryProgress`. Example `StreamingQueryProgress` output in JSON form.

### What changes were proposed in this pull request?
This PR proposes to add a new scalastyle rule to enforce not importing `scala.collection.Seq` and `scala.collection.IndexedSeq` which conflicts with `scala.Seq` and `scala.IndexedSeq`.
The problem occurs as Scala 2.13 changed the alias of `scala.Seq` and `scala.IndexedSeq`. Before Scala 2.13, they were `scala.collection.Seq` and `scala.collection.IndexedSeq`. After Scala 2.13, they become `scala.collection.immutable.Seq` and `scala.collection.immutable.IndexedSeq`.
Please refer below doc for more details.
https://docs.scala-lang.org/overviews/core/collections-migration-213.html
### Why are the changes needed?
We have seen Seq/IndexedSeq issues on cross-compilation of Scala 2.12 / 2.13. While I'm not sure this can prevent all cases, this will prevent the simple case of breaking cross compilation.
### Does this PR introduce _any_ user-facing change?
No change on end user. Contributors will be restricted but shouldn't block them doing the right thing.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR changes the unionByName with null filling logic to append new nested struct fields from the right side of the union to the schema versus sorting fields alphabetically. It removes the need to use UpdateField expressions, and just directly projects new nested structs from each side of the union with the correct schema. This changes the union'd schema from being alphabetically sorted previously to now "left dominant", where the fields from the left side of the union are included and then the missing ones from the right are added in the same order found originally.
### Why are the changes needed?
Certain nested structs would cause unionByName with null filling to error out due to part of the logic for rewriting the expression tree to sort the structs.
### Does this PR introduce _any_ user-facing change?
Yes, nested struct fields will be in a different order after unionByName with null filling than before, though shouldn't cause much effective difference.
### How was this patch tested?
Updated existing tests based on the new StructField ordering and added a new test for the case that was broken originally.

* Add a new repartition operator `RebalanceRepartition`.
* Support a new hint `REBALANCE`
After this patch, user can run this query:
```sql
SELECT /*+ REBALANCE(c) */ * FROM t
```
### Why are the changes needed?
Add a new hint to distingush if we can optimize it safely.
This new hint can let AQE optimize with `CustomShuffleReaderExec` safely. Currently, AQE can only coalesce shuffle partitions but can not expand shuffle partitions due to the semantics of output partitioning.
Let's say we have a query:
```sql
SELECT /*+ REPARTITION(col) */ * FROM t
```
AQE can not expand the shuffle partitions even if `col` is skewed because expanding shuffle partitions will break the hashed output paritioning of `RepartitionByExpression`. But if the query is use`REPARTITION_BY_AQE`, AQE can optimize it without considering the semantics of output partitioning.
### Does this PR introduce _any_ user-facing change?
Yes, a new hint.

… sum of the digits is greater than 38
### What changes were proposed in this pull request?
Since Spark 3.1.1, NULL is returned when casting a string with many decimal places to a decimal type. If the sum of the digits before and after the decimal point is less than 39, a value is returned. From 39 digits, however, NULL is returned.
This worked until Spark 3.0.X.
Code to reproduce:
A string with 2 decimal places in front of the decimal point and 37 decimal places after the decimal point returns null
```
val data = Seq(
"28.9259999999999983799625624669715762138",
"28.925999999999998379962562466971576213",

)
val df = data.toDF("num")
df.withColumn("numConverted", col("num").cast("decimal(38, 5)")).show()
```

### What changes were proposed in this pull request?
In a secure Yarn cluster, even though HBase or Kafka, or Hive services are not used in the user application, yarn client unnecessarily trying to generate Delegations token from these services. This will add additional delays while submitting spark application in a yarn cluster
Also during HBase delegation token generation step in the application submit stage, HBaseDelegationTokenProvider prints a full Exception Stack trace and it causes a noisy warning.
Apart from printing exception stack trace, Application submission taking more time as it retries connection to HBase master multiple times before it gives up. So, if HBase is not used in the user Applications, it is better to suggest User disable HBase Delegation Token generation.
This PR aims to avoid printing full Exception Stack by just printing just Exception name and also add a suggestion message to disable `Delegation Token generation` if service is not used in the Spark Application.
eg: `If HBase is not used, set spark.security.credentials.hbase.enabled to false`
### Why are the changes needed?
To avoid printing full Exception stack trace in WARN log

The analyzer will turn a `dataset.withColumn("colName", expressionWithWindowFunction)` method call to a `Project - Window - Project` chain in the logical plan. When this method is called multiple times in a row, then the projects can block the `Window` nodes from being transposed by the current `TransposeWindow` rule.

Introduction: this PR is a part of SPARK-10816 (`EventTime based sessionization (session window)`). Please refer #31937 to see the overall view of the code change. (Note that code diff could be diverged a bit.)
### What changes were proposed in this pull request?
This PR introduces MergingSessionsIterator, which enables to merge elements belong to the same session directly.
MergingSessionsIterator is a variant of SortAggregateIterator which merges the session windows based on the fact input rows are sorted by "group keys + the start time of session window". When merging windows, MergingSessionsIterator also applies aggregations on merged window, which eliminates the necessity on buffering inputs (which requires copying rows) and update the session spec for each input.
MergingSessionsIterator is quite performant compared to UpdatingSessionsIterator brought by SPARK-34888. Note that MergingSessionsIterator can only apply to the cases aggregation can be applied altogether, so there're still rooms for UpdatingSessionIterator to be used.
This issue also introduces MergingSessionsExec which is the physical node on leveraging MergingSessionsIterator to sort the input rows and aggregate rows according to the session windows.
### Why are the changes needed?
This part is a one of required on implementing SPARK-10816.

### Why are the changes needed?
As suggested [here](https://github.com/apache/spark/pull/32753#discussion_r655580942). To support column index in the vectorized reader path, we'll going to introduce more states to track.

### Why are the changes needed?
For Views, it is important to show consistent results even the ANSI configuration is different in the running session. This is why many expressions like 'Add'/'Divide' making the ANSI flag part of its case class parameter list.
We should make it consistent for the expression `Cast`

### What changes were proposed in this pull request?
The current OuterReference resolution is a bit weird: when the outer plan has more than one child, it resolves OuterReference from the output of each child, one by one, left to right.
This is incorrect in the case of join, as the column name can be ambiguous if both left and right sides output this column.
This PR fixes this bug by resolving OuterReference with `outerPlan.resolveChildren`, instead of something like `outerPlan.children.foreach(_.resolve(...))`
### Why are the changes needed?

### Does this PR introduce _any_ user-facing change?
The problem only occurs in join, and join condition doesn't support correlated subquery yet. So this PR only improves the error message. Before this PR, people see

### What changes were proposed in this pull request?
This PR fixes an issue that `IntervalUtils.toDayTimeIntervalString` doesn't consider the case that a day-time interval type is casted as another day-time interval type.
if data of `interval day to second` is casted as `interval hour to second`, the value of the day is multiplied by 24 and added to the value of hour. For example, `INTERVAL '1 2' DAY TO HOUR` will be `INTERVAL '26' HOUR` if it's casted.
If this behavior is intended, it should be stringified as `INTERVAL '26' HOUR` but currently, it will be `INTERVAL '2' HOUR`

We introduced `SparkSession.withActive` a while ago, and we use it when we need to run some code with a certain SparkSession as the active session.

### Why are the changes needed?
make sure we don't change the active session unexpectedly.
### Does this PR introduce _any_ user-facing change?
No. `makeCopy` is an internal function and I can't find a real case that this can change the active session. Mostly in an upper level, there is already a `SparkSession.withActive`, like `QueryExecution.executePhase`

### What changes were proposed in this pull request?
This is a followup of https://github.com/apache/spark/pull/33001 , to provide a more direct fix.
The regression in 3.1 was caused by the fact that we changed the parser and allow the parser to return CHAR/VARCHAR type. We should have replaced CHAR/VARCHAR with STRING before the data type flows into the query engine, however, `OrcUtils` is missed.
When reading ORC files, at the task side we will read the real schema from ORC file metadata, then apply filter pushdown. For some reason, the implementation turns ORC schema to Spark schema before filter pushdown, and this step does not strip CHAR/VARCHAR. Note, for Parquet we use the Parquet schema directly in filter pushdown, and do not this have problem.
This PR proposes to replace the CHAR/VARCHAR with STRING when turning ORC schema to Spark schema.

### What changes were proposed in this pull request?
Proposed changes in this pull request:
1. Introducing the `TestGroupState` interface which is inherited from `GroupState` so that testing related getters can be exposed in a controlled manner
2. Changing `GroupStateImpl` to inherit from `TestGroupState` interface, instead of directly from `GroupState`
3. Implementing `TestGroupState` object with `create()` method to forward inputs to the private `GroupStateImpl` constructor
4. User input validations have been added into `GroupStateImpl`'s `createForStreaming()` method to prevent users from creating invalid GroupState objects.
5. Replacing existing `GroupStateImpl` usages in sql pkg internal unit tests with the newly added `TestGroupState` to give user best practice about `TestGroupState` usage.
With the changes in this PR, the class hierarchy is changed from `GroupStateImpl` -> `GroupState` to `GroupStateImpl` -> `TestGroupState` -> `GroupState` (-> means inherits from)
### Why are the changes needed?
The internal `GroupStateImpl` implementation for the `GroupState` interface has no public constructors accessible outside of the sql pkg. However, the user-provided state transition function for `[map|flatMap]GroupsWithState` requires a `GroupState` object as the prevState input.
Currently, users are calling the Structured Streaming engine in their unit tests in order to instantiate such `GroupState` instances, which makes UTs cumbersome.
The proposed `TestGroupState` interface is to give users controlled access to the `GroupStateImpl` internal implementation to largely improve testability of Structured Streaming state transition functions.
**Usage Example**
```
import org.apache.spark.sql.streaming.TestGroupState
test(“Structured Streaming state update function”) {
var prevState = TestGroupState.create[UserStatus](
optionalState = Optional.empty[UserStatus],
timeoutConf = EventTimeTimeout,
batchProcessingTimeMs = 1L,
eventTimeWatermarkMs = Optional.of(1L),
hasTimedOut = false)
val userId: String = ...
val actions: Iterator[UserAction] = ...
assert(!prevState.hasUpdated)
updateState(userId, actions, prevState)
assert(prevState.hasUpdated)
}
```
### Does this PR introduce _any_ user-facing change?
Yes, the `TestGroupState` interface and its corresponding `create()` factory function in its companion object are introduced in this pull request for users to use in unit tests.
### How was this patch tested?
- New unit tests are added
- Existing GroupState unit tests are updated

### What changes were proposed in this pull request?
When SQL function `to_timestamp_ntz` has invalid format pattern input, throw a runtime exception with hints for the valid patterns, instead of throwing an upgrade exception with suggestions to use legacy formatters.
### Why are the changes needed?
As discussed in https://github.com/apache/spark/pull/32995/files#r655148980, there is an error message saying
"You may get a different result due to the upgrading of Spark 3.0: Fail to recognize 'yyyy-MM-dd GGGGG' pattern in the DateTimeFormatter. 1) You can set spark.sql.legacy.timeParserPolicy to LEGACY to restore the behavior before Spark 3.0"
This is not true for function to_timestamp_ntz, which only uses the Iso8601TimestampFormatter and added since Spark 3.2. We should improve it.

### What changes were proposed in this pull request?
Fix how we measure the metric `allUpdatesTimeMs` in `FlatMapGroupsWithStateExec` similar to other streaming stateful operators.
### Why are the changes needed?
Metric `allUpdatesTimeMs` meant to capture the start to end walltime of the operator `FlatMapGroupsWithStateExec`, but currently it just [captures](79362c4efc/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/FlatMapGroupsWithStateExec.scala (L121)) the iterator creation time.
Fix it to measure similar to how other stateful operators measure. Example one [here](79362c4efc/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/statefulOperators.scala (L406)). This measurement is not perfect due to the nature of the lazy iterator and also includes the time the consumer operator spent in processing the current operator output, but it should give a good signal when comparing the metric in one microbatch to the metric in another microbatch.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?

### What changes were proposed in this pull request?
This PR fixes error message shown when changing a column type to year-month/day-time interval type is attempted.
### Why are the changes needed?
It's for consistent behavior.
Updating column types to interval types are prohibited for V2 source tables.
So, if we attempt to update the type of a column to the conventional interval type, an error message like `Error in query: Cannot update <table> field <column> to interval type;`.
But, for year-month/day-time interval types, another error message like `Error in query: Cannot update <table> field <column>:<type> cannot be cast to interval year;`.
You can reproduce with the following procedure.
```
$ bin/spark-sql
spark-sql> SET spark.sql.catalog.mycatalog=<a catalog implementation class>;
spark-sql> CREATE TABLE mycatalog.t1(c1 int) USING <V2 datasource implementation class>;
spark-sql> ALTER TABLE mycatalog.t1 ALTER COLUMN c1 TYPE interval year to month;
```

Signed-off-by: Max Gekk <max.gekk@gmail.com>
### What changes were proposed in this pull request?
This PR fixes an issue that `IntervalUtils.toYearMonthIntervalString` doesn't consider the case that year-month interval type is casted as month interval type.
If a year-month interval data is casted as month interval, the value of the year is multiplied by `12` and added to the value of month. For example, `INTERVAL '1-2' YEAR TO MONTH` will be `INTERVAL '14' MONTH` if it's casted.
If this behavior is intended, it's stringified to be `'INTERVAL 14' MONTH` but currently, it will be `INTERVAL '2' MONTH`
### Why are the changes needed?
It's a bug if the behavior of cast is intended.
### Does this PR introduce _any_ user-facing change?
No, because this feature is not released yet.

### What changes were proposed in this pull request?
This patch proposes to add an internal config for ignoring metadata of `FileStreamSink` when reading the output path.
### Why are the changes needed?
`FileStreamSink` produces a metadata directory which logs output files per micro-batch. When we read from the output path, Spark will look at the metadata and ignore other files not in the log.
Normally it works well. But for some use-cases, we may need to ignore the metadata when reading the output path. For example, when we change the streaming query and must to run it with new checkpoint directory, we cannot use previous metadata. If we create a new metadata too, when we read the output path later in Spark, Spark only reads the files listed in the new metadata. The files written before we use new checkpoint and metadata are ignored by Spark.
Although seems we can output to different output directory every time, but it is bad idea as we will produce many directories unnecessarily.
We need a config for ignoring the metadata of `FileStreamSink` when reading the output path.
### Does this PR introduce _any_ user-facing change?

Make `CommandResult` in suitable package.
### Does this PR introduce _any_ user-facing change?
'No'.

### What changes were proposed in this pull request?
`RelationConversions` is actually an optimization rule while it's executed in the analysis phase.
For view, it's designed to only capture semantic configs, so we should ignore the optimization
configs that will be used in the analysis phase.
This PR also fixes the issue that view resolution will always use the default value for uncaptured config
### Why are the changes needed?
Bugfix
### Does this PR introduce _any_ user-facing change?
Yes, after this PR view resolution will respect the values set in the current session for the below configs

### What changes were proposed in this pull request?
This is a followup of https://github.com/apache/spark/pull/32513
It's hard to keep the command execution name for `DataFrameWriter`, as the command logical plan is a bit messy (DS v1, file source and hive and different command logical plans) and sometimes it's hard to distinguish "insert" and "save".
However, `DataFrameWriterV2` only produce v2 commands which are pretty clean. It's easy to keep the command execution name for them.

### 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.

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.

P.S. Reopening this since [spark upgraded](463daabd5a) its `hive.version` to `2.3.9` which does not have a dependency on `commons-httpclient`.

### 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.
### How was this patch tested?
By existing test suites.
Closes#32909 from MaxGekk/add-fields-to-YearMonthIntervalType.
