### What changes were proposed in this pull request?
Introduce `Name` and `Label` type aliases to distinguish what is expected instead of `Any` or `Union[Any, Tuple]`.
- `Label`: `Tuple[Any, ...]`
Internal expression for name-like metadata, like `index_names`, `column_labels`, and `column_label_names` in `InternalFrame`, and similar internal structures.
- `Name`: `Union[Any, Label]`
External expression for user-facing names, which can be scalar values or tuples.
### Why are the changes needed?
Currently `Any` or `Union[Any, Tuple]` is used for name-like types, but type aliases should be used to distinguish what is expected clearly.
### Does this PR introduce _any_ user-facing change?
No.

### 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.

### What changes were proposed in this pull request?
Provide the (configurable) ability to perform Avro-to-Catalyst schema field matching using the position of the fields instead of their names. A new `option` is added for the Avro datasource, `positionalFieldMatching`, which instructs `AvroSerializer`/`AvroDeserializer` to perform positional field matching instead of matching by name.
### Why are the changes needed?
This by-name matching is somewhat recent; prior to PR #24635, at least on the write path, schemas were matched by positionally ("structural" comparison). While by-name is better behavior as a default, it will be better to make this configurable by a user. Even at the time that PR #24635 was handled, there was [interest in making this behavior configurable](https://github.com/apache/spark/pull/24635#issuecomment-494205251), but it appears it went unaddressed.
There is precedence for configurability of this behavior as seen in PR #29737, which added this support for ORC. Besides this precedence, the behavior of Hive is to perform matching positionally ([ref](https://cwiki.apache.org/confluence/display/Hive/AvroSerDe#AvroSerDe-WritingtablestoAvrofiles)), so this is behavior that Hadoop/Hive ecosystem users are familiar with.
### Does this PR introduce _any_ user-facing change?
Yes, a new option is provided for the Avro datasource, `positionalFieldMatching`, which provides compatibility with Hive and pre-3.0.0 Spark behavior.
### How was this patch tested?
New unit tests are added within `AvroSuite`, `AvroSchemaHelperSuite`, and `AvroSerdeSuite`; and most of the existing tests within `AvroSerdeSuite` are adapted to perform the same test using by-name and positional matching to ensure feature parity.

### 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.

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.

### What changes were proposed in this pull request?
Currently ,we sets the environment variable `PYSPARK_PIN_THREAD` at the client side of `InhertiableThread` API for Py4J (`python/pyspark/util.py`). If the Py4J gateway is created somewhere else (e.g., Zeppelin, etc), it could introduce a breakage at:
```python
from pyspark import SparkContext
jvm = SparkContext._jvm
thread_connection = jvm._gateway_client.get_thread_connection()
# `AttributeError: 'GatewayClient' object has no attribute 'get_thread_connection'` (non-pinned thread mode)
# `get_thread_connection` is only in 'ClientServer' (pinned thread mode)
```
This PR proposes to check the given gateway created, and do the pinned thread mode behaviour accordingly so we can avoid any breakage when Py4J server/gateway is created separately from somewhere else without a pinned thread mode.
### Why are the changes needed?
To avoid any potential breakage.
### Does this PR introduce _any_ user-facing change?
No, the change happened only in the master (fdd7ca5f4e).
### How was this patch tested?
This is actually a partial revert of fdd7ca5f4e. As long as the existing tests pass, I guess we're all good.

2. Evaluate all children subexpressions when evaluating a subexpression.

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.

### What changes were proposed in this pull request?
This is the shuffle fetch side change where executors can fetch local/remote push-merged shuffle data from shuffle services. This is needed for push-based shuffle - SPIP [SPARK-30602](https://issues.apache.org/jira/browse/SPARK-30602).
The change adds support to the `ShuffleBlockFetchIterator` to fetch push-merged block meta and shuffle chunks from local and remote ESS. If the fetch of any of these fails, then the iterator fallsback to fetch the original shuffle blocks that belonged to the push-merged block.
### Why are the changes needed?

### What changes were proposed in this pull request?
This PR changes `SparkBuild.scala` to edit `config.properties` in `yarn` sub-module in build with SBT like as build with Maven does.
### Why are the changes needed?
yarn sub-module contains config.properties.
```
spark.yarn.isHadoopProvided = ${spark.yarn.isHadoopProvided}
```

The edited config.properties will be loaded at runtime to control how to populate Hadoop-related classpath.
If we build with Maven, these process works but doesn't with SBT.
If we build with SBT and deploy apps on YARN, the following warning appears and classpath is not populated correctly.
```
21/06/29 10:51:20 WARN config.package: Can not load the default value of `spark.yarn.isHadoopProvided` from `org/apache/spark/deploy/yarn/config.properties` with error, java.lang.IllegalArgumentException: For input string: "${spark.yarn.isHadoopProvided}". Using `false` as a default value.

spark.yarn.isHadoopProvided = false # In case build with -Pyarn and without -Phadoop-provided
spark.yarn.isHadoopProvided = true # In case build with -Pyarn and -Phadoop-provided
```

### What changes were proposed in this pull request?
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.

### What changes were proposed in this pull request?
Replace the type collection `AllTimestampTypes` with the new data type `AnyTimestampType`
### 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

Now we need to specify the python test cases by manually when we add a new testcase. Sometime, we forgot to add the testcase to module list, the testcase would not be executed.

### What changes were proposed in this pull request?
This PR fixes an issue that field names of structs generated by `arrays_zip` function could be unexpectedly re-written by analyzer/optimizer.
Here is an example.
```
val df = sc.parallelize(Seq((Array(1, 2), Array(3, 4)))).toDF("a1", "b1").selectExpr("arrays_zip(a1, b1) as zipped")
df.printSchema
root
|-- zipped: array (nullable = true)
| |-- 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
df.write.parquet("/tmp/test.parquet")
val df2 = spark.read.parquet("/tmp/test.parquet")
df2.printSchema
root
|-- zipped: array (nullable = true)
| |-- element: struct (containsNull = true)
| | |-- _1: integer (nullable = true) // Not OK. a1 is expected but got _1
| | |-- _2: integer (nullable = true) // Not OK. b1 is expected but got _2
```
This issue happens when aliases are eliminated by `AliasHelper.replaceAliasButKeepName` or `AliasHelper.trimNonTopLevelAliases` called via analyzer/optimizer
b89cd8d75a/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/Optimizer.scala (L883)b89cd8d75a/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala (L3759)
I investigated functions which can be affected this issue but I found only `arrays_zip` so far.
To fix this issue, this PR changes the definition of `ArraysZip` to retain field names to avoid being re-written by analyzer/optimizer.
### Why are the changes needed?
This is apparently a bug.
### Does this PR introduce _any_ user-facing change?
No. After this change, the field names are no longer re-written but it should be expected behavior for users.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR proposes to migrate the following `ALTER TABLE ... CHANGE COLUMN` command to use `UnresolvedTable` as a `child` to resolve the table identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).

### What changes were proposed in this pull request?
The PR is proposed to support creating a Column of numpy literal value in pandas-on-Spark. It consists of three changes mainly:
- Enable the `lit` function defined in `pyspark.pandas.spark.functions` to support numpy literals input.
```py
>>> from pyspark.pandas.spark import functions as SF
>>> SF.lit(np.int64(1))
Column<'CAST(1 AS BIGINT)'>
>>> SF.lit(np.int32(1))
Column<'CAST(1 AS INT)'>
>>> SF.lit(np.int8(1))
Column<'CAST(1 AS TINYINT)'>
>>> SF.lit(np.byte(1))
Column<'CAST(1 AS TINYINT)'>
>>> SF.lit(np.float32(1))
Column<'CAST(1.0 AS FLOAT)'>
```
- Substitute `F.lit` by `SF.lit`, that is, use `lit` function defined in `pyspark.pandas.spark.functions` rather than `lit` function defined in `pyspark.sql.functions` to allow creating columns out of numpy literals.
- Enable numpy literals input in `isin` method
Non-goal:
- Some pandas-on-Spark APIs use PySpark column-related APIs internally, and these column-related APIs don't support numpy literals, thus numpy literals are disallowed as input (e.g. `to_replace` parameter in `replace` API). This PR doesn't aim to adjust all of them. This PR adjusts `isin` only, because the PR is inspired by that (as https://github.com/databricks/koalas/issues/2161).
- To complete mappings between all kinds of numpy literals and Spark data types should be a followup task.
### Why are the changes needed?
Spark (`lit` function defined in `pyspark.sql.functions`) doesn't support creating a Column out of numpy literal value.
So `lit` function defined in `pyspark.pandas.spark.functions` is adjusted in order to support that in pandas-on-Spark.
### Does this PR introduce _any_ user-facing change?
Yes.
Before:
```py
>>> a = ps.DataFrame({'source': [1,2,3,4,5]})
>>> a.source.isin([np.int64(1), np.int64(2)])
Traceback (most recent call last):
...
AttributeError: 'numpy.int64' object has no attribute '_get_object_id'
```
After:
```py
>>> a = ps.DataFrame({'source': [1,2,3,4,5]})
>>> a.source.isin([np.int64(1), np.int64(2)])
0 True
1 True
2 False
3 False
4 False

### What changes were proposed in this pull request?
Currently, we calculate the `remoteBlockBytes` based on the original block info list. It's not efficient. Usually, it costs more ~25% time to be spent here.
If the original reducer size is big but the actual reducer size is small due to automatically partition coalescing of AQE, the reducer will take more time to calculate `remoteBlockBytes`.
We can reduce this cost via remote requests which contain merged block info lists.

### 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).
