Max Gekk 04c3125dcf [SPARK-34360][SQL] Support truncation of v2 tables
### What changes were proposed in this pull request?
1. Add new interface `TruncatableTable` which represents tables that allow atomic truncation.
2. Implement new method in `InMemoryTable` and in `InMemoryPartitionTable`.

### Why are the changes needed?
To support `TRUNCATE TABLE` for v2 tables.

### Does this PR introduce _any_ user-facing change?
Should not.

### How was this patch tested?
Added new tests to `TableCatalogSuite` that check truncation of non-partitioned and partitioned tables:
```
$ build/sbt "test:testOnly *TableCatalogSuite"
```

Closes #31475 from MaxGekk/dsv2-truncate-table.

Kousuke Saruta 82b33a3041 [SPARK-34379][SQL] Map JDBC RowID to StringType rather than LongType
### What changes were proposed in this pull request?

This PR fix an issue that `java.sql.RowId` is mapped to `LongType` and prefer `StringType`.

In the current implementation, JDBC RowID type is mapped to `LongType` except for `OracleDialect`, but there is no guarantee to be able to convert RowID to long.
`java.sql.RowId` declares `toString` and the specification of `java.sql.RowId` says

> _all methods on the RowId interface must be fully implemented if the JDBC driver supports the data type_
(https://docs.oracle.com/javase/8/docs/api/java/sql/RowId.html)

So, we should prefer StringType to LongType.

### Why are the changes needed?

This seems to be a potential bug.

### Does this PR introduce _any_ user-facing change?

Yes. RowID is mapped to StringType rather than LongType.

### How was this patch tested?

New test and  the existing test case `SPARK-32992: map Oracle's ROWID type to StringType` in `OracleIntegrationSuite` passes.

Closes #31491 from sarutak/rowid-type.

Sean Owen f78466dca6 [SPARK-7768][CORE][SQL] Open UserDefinedType as a Developer API
### What changes were proposed in this pull request?

UserDefinedType and UDTRegistration become public Developer APIs, not package-private to Spark.

### Why are the changes needed?

This proposes to simply open up the UserDefinedType class as a developer API. It was public in 1.x, but closed in 2.x for some possible redesign that does not seem to have happened.

Other libraries have managed to define UDTs anyway by inserting shims into the Spark namespace, and this evidently has worked OK. But package isolation in Java 9+ breaks this.

The logic here is mostly: this is de facto a stable API, so can at least be open to developers with the usual caveats about developer APIs.

Open questions:

- Is there in fact some important redesign that's needed before opening it? The comment to this effect is from 2016
- Is this all that needs to be opened up? Like PythonUserDefinedType?
- Should any of this be kept package-private?

This was first proposed in https://github.com/apache/spark/pull/16478 though it was a larger change, but, the other API issues it was fixing seem to have been addressed already (e.g. no need to return internal Spark types). It was never really reviewed.

My hunch is that there isn't much downside, and some upside, to just opening this as-is now.

### Does this PR introduce _any_ user-facing change?

UserDefinedType becomes visible to developers to subclass.

### How was this patch tested?

Existing tests; there is no change to the existing logic.

Zhichao Zhang 96bcb4bbe4 [SPARK-34283][SQL] Combines all adjacent 'Union' operators into a single 'Union' when using 'Dataset.union.distinct.union.distinct'
### What changes were proposed in this pull request?

Handled 'Deduplicate(Keys, Union)' operation in rule 'CombineUnions' to combine adjacent 'Union' operators  into a single 'Union' if necessary when using 'Dataset.union.distinct.union.distinct'.
Currently only handle distinct-like 'Deduplicate', where the keys == output, for example:
```
val df1 = Seq((1, 2, 3)).toDF("a", "b", "c")
val df2 = Seq((6, 2, 5)).toDF("a", "b", "c")
val df3 = Seq((2, 4, 3)).toDF("c", "a", "b")
val df4 = Seq((1, 4, 5)).toDF("b", "a", "c")
val unionDF1 = df1.unionByName(df2).dropDuplicates(Seq("b", "a", "c"))
      .unionByName(df3).dropDuplicates().unionByName(df4)
      .dropDuplicates("a")
```
In this case, **all Union operators will be combined**.
but,
```
val df1 = Seq((1, 2, 3)).toDF("a", "b", "c")
val df2 = Seq((6, 2, 5)).toDF("a", "b", "c")
val df3 = Seq((2, 4, 3)).toDF("c", "a", "b")
val df4 = Seq((1, 4, 5)).toDF("b", "a", "c")
val unionDF = df1.unionByName(df2).dropDuplicates(Seq("a"))
      .unionByName(df3).dropDuplicates("c").unionByName(df4)
      .dropDuplicates("b")
```
In this case, **all unions will not be combined, because the Deduplicate.keys doesn't equal to Union.output**.

### Why are the changes needed?

When using 'Dataset.union.distinct.union.distinct', the operator is  'Deduplicate(Keys, Union)', but AstBuilder transform sql-style 'Union' to operator 'Distinct(Union)', the rule 'CombineUnions' in Optimizer only handle 'Distinct(Union)' operator but not Deduplicate(Keys, Union).
Please see the detailed  description in [SPARK-34283](https://issues.apache.org/jira/browse/SPARK-34283).

### Does this PR introduce _any_ user-facing change?

No

This PR:
- Fixes a bug that prevents analysis of:
  ```
  CREATE TEMPORARY VIEW temp_view AS WITH cte AS (SELECT temp_func(0)) SELECT * FROM cte;
  SELECT * FROM temp_view
  ```
  by throwing:
  ```
  Undefined function: 'temp_func'. This function is neither a registered temporary function nor a permanent function registered in the database 'default'.
  ```
- and doesn't report analysis error when it should:
  ```
  CREATE TEMPORARY VIEW temp_view AS SELECT 0;
  CREATE VIEW view_on_temp_view AS WITH cte AS (SELECT * FROM temp_view) SELECT * FROM cte
  ```
  by properly collecting temporary objects from VIEW definitions with CTEs.

- Minor refactor to make the affected code more readable.

### Why are the changes needed?

Max Gekk b26e7b510b [SPARK-34314][SQL] Fix partitions schema inference
### What changes were proposed in this pull request?
Infer the partitions schema by:
1. interring the common type over all partition part values, and
2. casting those values to the common type

Before the changes:
1. Spark creates a literal with most appropriate type for concrete partition value i.e. `part0=-0` -> `Literal(0, IntegerType)`, `part0=abc` -> `Literal(UTF8String.fromString("abc"), StringType)`.
2. Finds the common type for all literals of a partition column. For the example above, it is `StringType`.
3. Casts those literal to the desired type:
  - `Cast(Literal(0, IntegerType), StringType)` -> `UTF8String.fromString("0")`
  - `Cast(Literal(UTF8String.fromString("abc", StringType), StringType)` -> `UTF8String.fromString("abc")`

In the example, we get a partition part value "0" which is different from the original one "-0". Spark shouldn't modify partition part values of the string type because it can influence on query results.

Closes #31423

### Why are the changes needed?
The changes fix the bug demonstrated by the example:
1. There are partitioned parquet files (file format doesn't matter):
```
/private/var/folders/p3/dfs6mf655d7fnjrsjvldh0tc0000gn/T/spark-e09eae99-7ecf-4ab2-b99b-f63f8dea658d
├── _SUCCESS
├── part=-0
│   └── part-00001-02144398-2896-4d21-9628-a8743d098cb4.c000.snappy.parquet
└── part=AA
    └── part-00000-02144398-2896-4d21-9628-a8743d098cb4.c000.snappy.parquet
```
placed to two partitions "AA" and **"-0"**.

2. When reading them w/o specified schema:
```
val df = spark.read.parquet(path)
df.printSchema()
root
 |-- id: integer (nullable = true)
 |-- part: string (nullable = true)
```
the inferred type of the partition column `part` is the **string** type.
3. The expected values in the column `part` are "AA" and "-0" but we get:
```
df.show(false)
+---+----+
|id |part|
+---+----+
|0  |AA  |
|1  |0   |
+---+----+
```
So, Spark returns **"0"** instead of **"-0"**.

Chao Sun 27873280ff [SPARK-32703][SQL] Replace deprecated API calls from SpecificParquetRecordReaderBase
### What changes were proposed in this pull request?

Currently in `SpecificParquetRecordReaderBase` we use deprecated APIs in a few places from Parquet, such as `readFooter`, `ParquetInputSplit`, `new ParquetFileReader`, `filterRowGroups`, etc. This replaces these with the newer APIs. In specific this:
- Replaces `ParquetInputSplit` with `FileSplit`. We never use specific things in the former such as `rowGroupOffsets` so the swap is pretty simple.
- Removes `readFooter` calls by using `ParquetFileReader.open`
- Replace deprecated `ParquetFileReader` ctor with the newer API which takes `ParquetReadOptions`.
- Removes the unnecessary handling of case when `rowGroupOffsets` is not null. It seems this never happens.

### Why are the changes needed?

The aforementioned APIs were deprecated and is going to be removed at some point in future. This is to ensure better supportability.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

This is a cleanup and relies on existing tests on the relevant code paths.

Steve Loughran ff5115c3ac [SPARK-33739][SQL] Jobs committed through the S3A Magic committer don't track bytes
BasicWriteStatsTracker to probe for a custom Xattr if the size of
the generated file is 0 bytes; if found and parseable use that as
the declared length of the output.

The matching Hadoop patch in HADOOP-17414:

* Returns all S3 object headers as XAttr attributes prefixed "header."
* Sets the custom header x-hadoop-s3a-magic-data-length to the length of
  the data in the marker file.

As a result, spark job tracking will correctly report the amount of data uploaded
and yet to materialize.

### Why are the changes needed?

Now that S3 is consistent, it's a lot easier to use the S3A "magic" committer
which redirects a file written to `dest/__magic/job_0011/task_1245/__base/year=2020/output.avro`
to its final destination `dest/year=2020/output.avro` , adding a zero byte marker file at
the end and a json file `dest/__magic/job_0011/task_1245/__base/year=2020/output.avro.pending`
containing all the information for the job committer to complete the upload.

But: the write tracker statictics don't show progress as they measure the length of the
created file, find the marker file and report 0 bytes.
By probing for a specific HTTP header in the marker file and parsing that if
retrieved, the real progress can be reported.

There's a matching change in Hadoop [https://github.com/apache/hadoop/pull/2530](https://github.com/apache/hadoop/pull/2530)
which adds getXAttr API support to the S3A connector and returns the headers; the magic
committer adds the relevant attributes.

If the FS being probed doesn't support the XAttr API, the header is missing
or the value not a positive long then the size of 0 is returned.

### Does this PR introduce _any_ user-facing change?

No

### How was this patch tested?

New tests in BasicWriteTaskStatsTrackerSuite which use a filter FS to
implement getXAttr on top of LocalFS; this is used to explore the set of
options:
* no XAttr API implementation (existing tests; what callers would see with
  most filesystems)
* no attribute found (HDFS, ABFS without the attribute)
* invalid data of different forms

All of these return Some(0) as file length.

The Hadoop PR verifies XAttr implementation in S3A and that
the commit protocol attaches the header to the files.

External downstream testing has done the full hadoop+spark end
to end operation, with manual review of logs to verify that the
data was successfully collected from the attribute.

Max Gekk 5957bc18a1 [SPARK-34451][SQL] Add alternatives for datetime rebasing SQL configs and deprecate legacy configs
### What changes were proposed in this pull request?
Move the datetime rebase SQL configs from the `legacy` namespace by:
1. Renaming of the existing rebase configs like `spark.sql.legacy.parquet.datetimeRebaseModeInRead` -> `spark.sql.parquet.datetimeRebaseModeInRead`.
2. Add the legacy configs as alternatives
3. Deprecate the legacy rebase configs.

### Why are the changes needed?
The rebasing SQL configs like `spark.sql.legacy.parquet.datetimeRebaseModeInRead` can be used not only for migration from previous Spark versions but also to read/write datatime columns saved by other systems/frameworks/libs. So, the configs shouldn't be considered as legacy configs.

### Does this PR introduce _any_ user-facing change?
Should not. Users will see a warning if they still use one of the legacy configs.

### How was this patch tested?
1. Manually checking new configs:
```scala
scala> spark.conf.get("spark.sql.parquet.datetimeRebaseModeInRead")
res0: String = EXCEPTION

scala> spark.conf.set("spark.sql.legacy.parquet.datetimeRebaseModeInRead", "LEGACY")
21/02/17 14:57:10 WARN SQLConf: The SQL config 'spark.sql.legacy.parquet.datetimeRebaseModeInRead' has been deprecated in Spark v3.2 and may be removed in the future. Use 'spark.sql.parquet.datetimeRebaseModeInRead' instead.

scala> spark.conf.get("spark.sql.parquet.datetimeRebaseModeInRead")
res2: String = LEGACY
```
2. By running a datetime rebasing test suite:
```
$ build/sbt "test:testOnly *ParquetRebaseDatetimeV1Suite"
```

Kousuke Saruta dd6383f0a3 [SPARK-34333][SQL] Fix PostgresDialect to handle money types properly
### What changes were proposed in this pull request?

This PR changes the type mapping for `money` and `money[]`  types for PostgreSQL.
Currently, those types are tried to convert to `DoubleType` and `ArrayType` of `double` respectively.
But the JDBC driver seems not to be able to handle those types properly.

https://github.com/pgjdbc/pgjdbc/issues/100
https://github.com/pgjdbc/pgjdbc/issues/1405

Due to these issue, we can get the error like as follows.

money type.
```
[info]   org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 0.0 failed 1 times, most recent failure: Lost task 0.0 in stage 0.0 (TID 0) (192.168.1.204 executor driver): org.postgresql.util.PSQLException: Bad value for type double : 1,000.00

```

money[] type.

[info] 	at org.postgresql.jdbc.PgArray.getArray(PgArray.java:111)
```

For money type, a known workaround is to treat it as string so this PR do it.
For money[], however, there is no reasonable workaround so this PR remove the support.

### Why are the changes needed?

This is a bug.

### Does this PR introduce _any_ user-facing change?

Yes. As of this PR merged, money type is mapped to `StringType` rather than `DoubleType` and the support for money[] is stopped.
For money type, if the value is less than one thousand,  `$100.00` for instance, it works without this change so I also updated the migration guide because it's a behavior change for such small values.
On the other hand, money[] seems not to work with any value but mentioned in the migration guide just in case.

### How was this patch tested?

New test.

Closes #31442 from sarutak/fix-for-money-type.

Max Gekk 03161055de [SPARK-34424][SQL][TESTS] Fix failures of HiveOrcHadoopFsRelationSuite
### What changes were proposed in this pull request?
Modify `RandomDataGenerator.forType()` to allow generation of dates/timestamps that are valid in both Julian and Proleptic Gregorian calendars. Currently, the function can produce a date (for example `1582-10-06`) which is valid in the Proleptic Gregorian calendar. Though it cannot be saved to ORC files AS IS since ORC format (ORC libs in fact) assumes Julian calendar. So, Spark shifts `1582-10-06` to the next valid date `1582-10-15` while saving it to ORC files. And as a consequence of that, the test fails because it compares original date `1582-10-06` and the date `1582-10-15` loaded back from the ORC files.

In this PR, I propose to generate valid dates/timestamps in both calendars for ORC datasource till SPARK-34440 is resolved.

### Why are the changes needed?
The changes fix failures of `HiveOrcHadoopFsRelationSuite`. For instance, the test "test all data types" fails with the seed **610710213676**:
```
== Results ==

Mention the DS options introduced by https://github.com/apache/spark/pull/31529 and by https://github.com/apache/spark/pull/31489 in `SparkUpgradeException`.

### Why are the changes needed?

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the error message is:

_org.apache.spark.SparkUpgradeException: You may get a different result due to the upgrading of Spark 3.0: reading dates before 1582-10-15 or timestamps before 1900-01-01T00:00:00Z from Parquet files can be ambiguous, as the files may be written by Spark 2.x or legacy versions of Hive, which uses a legacy hybrid calendar that is different from Spark 3.0+'s Proleptic Gregorian calendar. See more details in SPARK-31404. You can set the SQL config 'spark.sql.legacy.parquet.datetimeRebaseModeInRead' or the datasource option 'datetimeRebaseMode' to 'LEGACY' to rebase the datetime values w.r.t. the calendar difference during reading. To read the datetime values as it is, set the SQL config 'spark.sql.legacy.parquet.datetimeRebaseModeInRead' or the datasource option 'datetimeRebaseMode' to 'CORRECTED'._

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

This PR proposes to support `ifExists` flag for v2 `ALTER TABLE ... UNSET TBLPROPERTIES` command. Currently, the flag is not respected and the command behaves as `ifExists = true` where the command always succeeds when the properties do not exist.

### Does this PR introduce _any_ user-facing change?

Yes, now if the property does not exist and `IF EXISTS` is not specified, the command will fail:

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

This patch proposes to throw exception if non-streaming `Deduplicate` is not replaced by aggregate in query planner.

### Why are the changes needed?

We replace some operations in the query optimizer. For them we throw some exceptions accordingly in query planner if these logical nodes are not replaced. But `Deduplicate` is missing and it opens a possible hole. For code consistency and to prevent possible unexpected query planning error, we should add similar exception case to query planner.

David Li 9b875ceada [SPARK-32953][PYTHON][SQL] Add Arrow self_destruct support to toPandas
### What changes were proposed in this pull request?

Creating a Pandas dataframe via Apache Arrow currently can use twice as much memory as the final result, because during the conversion, both Pandas and Arrow retain a copy of the data. Arrow has a "self-destruct" mode now (Arrow >= 0.16) to avoid this, by freeing each column after conversion. This PR integrates support for this in toPandas, handling a couple of edge cases:

self_destruct has no effect unless the memory is allocated appropriately, which is handled in the Arrow serializer here. Essentially, the issue is that self_destruct frees memory column-wise, but Arrow record batches are oriented row-wise:

```
Record batch 0: allocation 0: column 0 chunk 0, column 1 chunk 0, ...
Record batch 1: allocation 1: column 0 chunk 1, column 1 chunk 1, ...
```

In this scenario, Arrow will drop references to all of column 0's chunks, but no memory will actually be freed, as the chunks were just slices of an underlying allocation. The PR copies each column into its own allocation so that memory is instead arranged as so:

```
Record batch 0: allocation 0 column 0 chunk 0, allocation 1 column 1 chunk 0, ...
Record batch 1: allocation 2 column 0 chunk 1, allocation 3 column 1 chunk 1, ...
```

The optimization is disabled by default, and can be enabled with the Spark SQL conf "spark.sql.execution.arrow.pyspark.selfDestruct.enabled" set to "true". We can't always apply this optimization because it's more likely to generate a dataframe with immutable buffers, which Pandas doesn't always handle well, and because it is slower overall (since it only converts one column at a time instead of in parallel).

### Why are the changes needed?

This lets us load larger datasets - in particular, with N bytes of memory, before we could never load a dataset bigger than N/2 bytes; now the overhead is more like N/1.25 or so.

### Does this PR introduce _any_ user-facing change?

Yes - it adds a new SQL conf "spark.sql.execution.arrow.pyspark.selfDestruct.enabled"

### How was this patch tested?

See the [mailing list](http://apache-spark-developers-list.1001551.n3.nabble.com/DISCUSS-Reducing-memory-usage-of-toPandas-with-Arrow-quot-self-destruct-quot-option-td30149.html) - it was tested with Python memory_profiler. Unit tests added to check memory within certain bounds and correctness with the option enabled.

gengjiaan 32a523b56f [SPARK-34234][SQL] Remove TreeNodeException that didn't work
### What changes were proposed in this pull request?
`TreeNodeException` causes the error msg not clear and it didn't work well.
Because the `TreeNodeException` looks redundancy, we could remove it.

There are show a case:
```
val df = Seq(("1", 1), ("1", 2), ("2", 3), ("2", 4)).toDF("x", "y")
val hashAggDF = df.groupBy("x").agg(c, sum("y"))
```
The above code will use `HashAggregateExec`. In order to ensure that an exception will be thrown when executing `HashAggregateExec`, I added `throw new RuntimeException("calculate error")` into 72b7f8abfb/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/HashAggregateExec.scala (L85)

So, if the above code is executed, `RuntimeException("calculate error")` will be thrown.
Before this PR, the error is:

Chao Sun 0986f16c8d [SPARK-34347][SQL] CatalogImpl.uncacheTable should invalidate in cascade for temp views
### What changes were proposed in this pull request?

This PR includes the following changes:
1. in `CatalogImpl.uncacheTable`, invalidate caches in cascade when the target table is
 a temp view, and `spark.sql.legacy.storeAnalyzedPlanForView` is false (default value).
2. make `SessionCatalog.lookupTempView` public and return processed temp view plan (i.e., with `View` op).

### Why are the changes needed?

Following [SPARK-34052](https://issues.apache.org/jira/browse/SPARK-34052) (#31107), we should invalidate in cascade for `CatalogImpl.uncacheTable` when the table is a temp view, so that the behavior is consistent.

### Does this PR introduce _any_ user-facing change?

Yes, now `SQLContext.uncacheTable` will drop temp view in cascade by default.

### How was this patch tested?

Added a UT

MrPowers e6753c9402 [SPARK-33995][SQL] Expose make_interval as a Scala function
### What changes were proposed in this pull request?

This pull request exposes the `make_interval` function, [as suggested here](https://github.com/apache/spark/pull/31000#pullrequestreview-560812433), and as agreed to [here](https://github.com/apache/spark/pull/31000#issuecomment-754856820) and [here](https://github.com/apache/spark/pull/31000#issuecomment-755040234).

This powerful little function allows for idiomatic datetime arithmetic via the Scala API:

```scala
// add two hours
df.withColumn("plus_2_hours", col("first_datetime") + make_interval(hours = lit(2)))

// subtract one week and 30 seconds
col("d") - make_interval(weeks = lit(1), secs = lit(30))
```

The `make_interval` [SQL function](https://github.com/apache/spark/pull/26446) already exists.

Here is [the JIRA ticket](https://issues.apache.org/jira/browse/SPARK-33995) for this PR.

### Why are the changes needed?

The Spark API makes it easy to perform datetime addition / subtraction with months (`add_months`) and days (`date_add`).  Users need to write code like this to perform datetime addition with years, weeks, hours, minutes, or seconds:

```scala
df.withColumn("plus_2_hours", expr("first_datetime + INTERVAL 2 hours"))
```

We don't want to force users to manipulate SQL strings when they're using the Scala API.

### Does this PR introduce _any_ user-facing change?

Yes, this PR adds `make_interval` to the `org.apache.spark.sql.functions` API.

This single function will benefit a lot of users.  It's a small increase in the surface of the API for a big gain.

### How was this patch tested?

This was tested via unit tests.

Angerszhuuuu 123365e05c [SPARK-34240][SQL] Unify output of SHOW TBLPROPERTIES clause's output attribute's schema and ExprID
### What changes were proposed in this pull request?
Passing around the output attributes should have more benefits like keeping the exprID unchanged to avoid bugs when we apply more operators above the command output DataFrame.

This PR did 2 things :

1. After this pr, a `SHOW TBLPROPERTIES` clause's output shows `key` and `value` columns whether you specify the table property `key`. Before this pr, a `SHOW TBLPROPERTIES` clause's output only show a `value` column when you specify the table property `key`..
2. Keep `SHOW TBLPROPERTIES` command's output attribute exprId unchanged.

### Why are the changes needed?
 1. Keep `SHOW TBLPROPERTIES`'s output schema consistence
 2. Keep `SHOW TBLPROPERTIES` command's output attribute exprId unchanged.

### Does this PR introduce _any_ user-facing change?
After this pr, a `SHOW TBLPROPERTIES` clause's output shows `key` and `value` columns whether you specify the table property `key`. Before this pr, a `SHOW TBLPROPERTIES` clause's output only show a `value` column when you specify the table property `key`.

Before this PR:
```
sql > SHOW TBLPROPERTIES tabe_name('key')
value
value_of_key
```

After this PR
```
sql > SHOW TBLPROPERTIES tabe_name('key')
key value
key value_of_key
```

### How was this patch tested?
Added UT

Kousuke Saruta f79305a402 [SPARK-34311][SQL] PostgresDialect can't treat arrays of some types
### What changes were proposed in this pull request?

This PR fixes the issue that `PostgresDialect` can't treat arrays of some types.
Though PostgreSQL supports wide range of types (https://www.postgresql.org/docs/13/datatype.html),  the current `PostgresDialect` can't treat arrays of the following types.

* xml
* tsvector
* tsquery
* macaddr
* macaddr8
* txid_snapshot
* pg_snapshot
* point
* line
* lseg
* box
* path
* polygon
* circle
* pg_lsn
* bit varying
* interval

NOTE: PostgreSQL doesn't implement arrays of serial types so this PR doesn't care about them.

### Why are the changes needed?

To provide better support with PostgreSQL.

### Does this PR introduce _any_ user-facing change?

Yes. PostgresDialect can handle arrays of types shown above.

### How was this patch tested?

New test.

Terry Kim c92e408aa1 [SPARK-34388][SQL] Propagate the registered UDF name to ScalaUDF, ScalaUDAF and ScalaAggregator
### What changes were proposed in this pull request?

This PR proposes to propagate the name used for registering UDFs to `ScalaUDF`, `ScalaUDAF` and `ScaalAggregator`.

Note that `PythonUDF` gets the name correctly: 466c045bfa/python/pyspark/sql/udf.py (L358-L359)
, and same for Hive UDFs:
466c045bfa/sql/hive/src/main/scala/org/apache/spark/sql/hive/HiveSessionCatalog.scala (L67)
### Why are the changes needed?

This PR can help in the following scenarios:
1) Better EXPLAIN output
2) By adding  `def name: String` to `UserDefinedExpression`, we can match an expression by `UserDefinedExpression` and look up the catalog, an use case needed for #31273.

### Does this PR introduce _any_ user-facing change?

The EXPLAIN output involving udfs will be changed to use the name used for UDF registration.

For example, for the following:
```
sql("CREATE TEMPORARY FUNCTION test_udf AS 'org.apache.spark.examples.sql.Spark33084'")
sql("SELECT test_udf(col1) FROM VALUES (1), (2), (3)").explain(true)
```
The output of the optimized plan will change from:
```
Aggregate [spark33084(cast(col1#223 as bigint), org.apache.spark.examples.sql.Spark330846906be0f, 1, 1) AS spark33084(col1)#237]
+- LocalRelation [col1#223]
```
to
```
Aggregate [test_udf(cast(col1#223 as bigint), org.apache.spark.examples.sql.Spark330847a62d697, 1, 1, Some(test_udf)) AS test_udf(col1)#237]

Linhong Liu 037bfb2dbc [SPARK-33438][SQL] Eagerly init objects with defined SQL Confs for command set -v
### What changes were proposed in this pull request?
In Spark, `set -v` is defined as "Queries all properties that are defined in the SQLConf of the sparkSession".
But there are other external modules that also define properties and register them to SQLConf. In this case,
it can't be displayed by `set -v` until the conf object is initiated (i.e. calling the object at least once).

In this PR, I propose to eagerly initiate all the objects registered to SQLConf, so that `set -v` will always output
the completed properties.

### Why are the changes needed?
Improve the `set -v` command to produces completed and  deterministic results

### Does this PR introduce _any_ user-facing change?
`set -v` command will dump more configs

### How was this patch tested?

Max Gekk a85490659f [SPARK-34377][SQL] Add new parquet datasource options to control datetime rebasing in read
### What changes were proposed in this pull request?
In the PR, I propose new options for the Parquet datasource:
1. `datetimeRebaseMode`
2. `int96RebaseMode`

Both options influence on loading ancient dates and timestamps column values from parquet files. The `datetimeRebaseMode` option impacts on loading values of the `DATE`, `TIMESTAMP_MICROS` and `TIMESTAMP_MILLIS` types, `int96RebaseMode` impacts on loading of `INT96` timestamps.

The options support the same values as the SQL configs `spark.sql.legacy.parquet.datetimeRebaseModeInRead` and `spark.sql.legacy.parquet.int96RebaseModeInRead` namely;
- `"LEGACY"`, when an option is set to this value, Spark rebases dates/timestamps from the legacy hybrid calendar (Julian + Gregorian) to the Proleptic Gregorian calendar.
- `"CORRECTED"`, dates/timestamps are read AS IS from parquet files.
- `"EXCEPTION"`, when it is set as an option value, Spark will fail the reading if it sees ancient dates/timestamps that are ambiguous between the two calendars.

### Why are the changes needed?
1. New options will allow to load parquet files from at least two sources in different rebasing modes in the same query. For instance:
```scala
val df1 = spark.read.option("datetimeRebaseMode", "legacy").parquet(folder1)
val df2 = spark.read.option("datetimeRebaseMode", "corrected").parquet(folder2)
df1.join(df2, ...)
```
Before the changes, it is impossible because the SQL config `spark.sql.legacy.parquet.datetimeRebaseModeInRead`  influences on both reads.

2. Mixing of Dataset/DataFrame and RDD APIs should become possible. Since SQL configs are not propagated through RDDs, the following code fails on ancient timestamps:
```scala
spark.conf.set("spark.sql.legacy.parquet.datetimeRebaseModeInRead", "legacy")
spark.read.parquet(folder).distinct.rdd.collect()
```

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
By running the modified test suites:
```
$ build/sbt "sql/test:testOnly *ParquetRebaseDatetimeV1Suite"
$ build/sbt "sql/test:testOnly *ParquetRebaseDatetimeV2Suite"
```

gengjiaan 2c243c93d9 [SPARK-34157][SQL] Unify output of SHOW TABLES and pass output attributes properly
### What changes were proposed in this pull request?
The current implement of some DDL not unify the output and not pass the output properly to physical command.
Such as: The `ShowTables` output attributes `namespace`, but `ShowTablesCommand` output attributes `database`.

As the query plan, this PR pass the output attributes from `ShowTables` to `ShowTablesCommand`, `ShowTableExtended ` to `ShowTablesCommand`.

Take `show tables` and `show table extended like 'tbl'` as example.
The output before this PR:
`show tables`
|database|tableName|isTemporary|
-- | -- | --
| default|      tbl|      false|

If catalog is v2 session catalog, the output before this PR:
|namespace|tableName|
-- | --
| default|      tbl

`show table extended like 'tbl'`
|database|tableName|isTemporary|         information|
-- | -- | -- | --
| default|      tbl|      false|Database: default...|

The output after this PR:
`show tables`
|namespace|tableName|isTemporary|
-- | -- | --
|  default|      tbl|      false|

`show table extended like 'tbl'`
|namespace|tableName|isTemporary|         information|
-- | -- | -- | --
|  default|      tbl|      false|Database: default...|

### Why are the changes needed?
This PR have benefits as follows:
First, Unify schema for the output of SHOW TABLES.
Second, pass the output attributes could keep the expr ID unchanged, so that avoid bugs when we apply more operators above the command output dataframe.

### Does this PR introduce _any_ user-facing change?
Yes.
The output schema of `SHOW TABLES` replace `database` by `namespace`.

### How was this patch tested?
Jenkins test.

“attilapiros” cc508d17c7 [SPARK-34370][SQL] Support Avro schema evolution for partitioned Hive tables using "avro.schema.url"
### What changes were proposed in this pull request?

With https://github.com/apache/spark/pull/31133 Avro schema evolution is introduce for partitioned hive tables where the schema is given by `avro.schema.literal`.
Here that functionality is extended to support schema evolution where the schema is defined via `avro.schema.url`.

### Why are the changes needed?

Without this PR the problem described in https://github.com/apache/spark/pull/31133 can be reproduced by tables where `avro.schema.url` is used. As in this case always the property value given at partition level is used for the `avro.schema.url`.

So for example when a new column (with a default value) is added to the table then one the following problem happens:
-  when the new field is added after the last one the cell values will be null values instead of the default value
-  when the schema is extended somewhere before the last field then values will be listed for the wrong column positions

Similar error will happen when one of the field is removed from the schema.

For details please check the attached unit tests where both cases are checked.

### Does this PR introduce _any_ user-facing change?

Fixes the potential value error.

### How was this patch tested?

The existing unit tests for schema evolution is generalized and reused.
New tests:
- `SPARK-34370: support Avro schema evolution (add column with avro.schema.url)`
- `SPARK-34370: support Avro schema evolution (remove column with avro.schema.url)`

“attilapiros” e614f34c7a [SPARK-26836][SQL] Supporting Avro schema evolution for partitioned Hive tables with "avro.schema.literal"
### What changes were proposed in this pull request?

Before this PR for a partitioned Avro Hive table when the SerDe is configured to read the partition data
the table level properties were overwritten by the partition level properties.

This PR changes this ordering by giving table level properties higher precedence  thus when a new evolved schema
is set for the table this new schema will be used to read the partition data and not the original schema which was used for writing the data.

This new behavior is consistent with Apache Hive.
See the example used in the unit test `SPARK-26836: support Avro schema evolution`, in Hive this results in:

```

### Why are the changes needed?

Without this change the old schema would be used. This can use a correctness issue when the new schema introduces
a new field with a default value (following the rules of schema evolution) before an existing field.
In this case the rows coming from the partition where the old schema was used will **contain values in wrong column positions**.

For example check the attached unit test `SPARK-26836: support Avro schema evolution`

Without this fix the result of the select on the table would be:

```
+----------+----------+----------+
|      col1|      col2|        ds|
+----------+----------+----------+
|col2_value|      null|1981-01-07|
|col1_value|col2_value|1983-04-27|
+----------+----------+----------+

```

With this fix:

```
+------------+----------+----------+
|        col1|      col2|        ds|
+------------+----------+----------+
|col1_default|col2_value|1981-01-07|
|  col1_value|col2_value|1983-04-27|
+------------+----------+----------+
```

### Does this PR introduce _any_ user-facing change?

Just fixes the value errors.
When a new column is introduced even to the last position then instead of 'null' the given default will be used.

### How was this patch tested?

This was tested with the unit tested included to the PR.
And manually on Apache Spark / Hive.

Cheng Su 76baaf7465 [SPARK-32985][SQL] Decouple bucket scan and bucket filter pruning for data source v1
### What changes were proposed in this pull request?

As a followup from discussion in https://github.com/apache/spark/pull/29804#discussion_r493100510 . Currently in data source v1 file scan `FileSourceScanExec`, [bucket filter pruning will only take effect with bucket table scan](https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L542 ). However this is unnecessary, as bucket filter pruning can also happen if we disable bucketed table scan. Read files with bucket hash partitioning, and bucket filter pruning are two orthogonal features, and do not need to couple together.

### Why are the changes needed?

This help query leverage the benefit from bucket filter pruning to save CPU/IO to not read unnecessary bucket files, and do not bound by bucket table scan when the parallelism of tasks is a concern.

In addition, this also resolves the issue to reduce number of tasks launched for simple query with bucket column filter - SPARK-33207, because with bucket scan, we launch # of tasks to equal to # of buckets, and this is unnecessary.

### Does this PR introduce _any_ user-facing change?

Users will notice query to start pruning irrelevant files for reading bucketed table, when disabling bucketing. If the input data does not follow spark data source bucketing convention, by default exception will be thrown and query will be failed. The exception can be bypassed with setting config `spark.sql.files.ignoreCorruptFiles` to true.

### How was this patch tested?

Added unit test in `BucketedReadSuite.scala` to make all existing unit tests for bucket filter work with this PR.

Closes #31413 from c21/bucket-pruning.

Wenchen Fan 989eb6884d [SPARK-34331][SQL] Speed up DS v2 metadata col resolution
### What changes were proposed in this pull request?

This is a follow-up of https://github.com/apache/spark/pull/28027

https://github.com/apache/spark/pull/28027 added a DS v2 API that allows data sources to produce metadata/hidden columns that can only be seen when it's explicitly selected. The way we integrate this API into Spark is:
1. The v2 relation gets normal output and metadata output from the data source, and the metadata output is excluded from the plan output by default.
2. column resolution can resolve `UnresolvedAttribute` with metadata columns, even if the child plan doesn't output metadata columns.
3. An analyzer rule searches the query plan, trying to find a node that has missing inputs. If such node is found, transform the sub-plan of this node, and update the v2 relation to include the metadata output.

The analyzer rule in step 3 brings a perf regression, for queries that do not read v2 tables at all. This rule will calculate `QueryPlan.inputSet` (which builds an `AttributeSet` from outputs of all children) and `QueryPlan.missingInput` (which does a set exclusion and creates a new `AttributeSet`) for every plan node in the query plan. In our benchmark, the TPCDS query compilation time gets increased by more than 10%

This PR proposes a simple way to improve it: we add a special metadata entry to the metadata attribute, which allows us to quickly check if a plan needs to add metadata columns: we just check all the references of this plan, and see if the attribute contains the special metadata entry, instead of calculating `QueryPlan.missingInput`.

This PR also fixes one bug: we should not change the final output schema of the plan, if we only use metadata columns in operators like filter, sort, etc.

### Why are the changes needed?

Fix perf regression in SQL query compilation, and fix a bug.

### Does this PR introduce _any_ user-facing change?

No

Kent Yao 961c85166a [SPARK-34346][CORE][SQL] io.file.buffer.size set by spark.buffer.size will override by loading hive-site.xml accidentally may cause perf regression
### What changes were proposed in this pull request?

In many real-world cases, when interacting with hive catalog through Spark SQL, users may just share the `hive-site.xml` for their hive jobs and make a copy to `SPARK_HOME`/conf w/o modification. In Spark, when we generate Hadoop configurations, we will use `spark.buffer.size(65536)` to reset `io.file.buffer.size(4096)`. But when we load the hive-site.xml, we may ignore this behavior and reset `io.file.buffer.size` again according to `hive-site.xml`.

1. The configuration priority for setting Hadoop and Hive config here is not right, while literally, the order should be `spark > spark.hive > spark.hadoop > hive > hadoop`

2. This breaks `spark.buffer.size` congfig's behavior for tuning the IO performance w/ HDFS if there is an existing `io.file.buffer.size` in hive-site.xml

### Why are the changes needed?

Jungtaek Lim (HeartSaVioR) fbe726f5b1 [SPARK-34339][CORE][SQL] Expose the number of total paths in Utils.buildLocationMetadata()
### What changes were proposed in this pull request?

This PR proposes to expose the number of total paths in Utils.buildLocationMetadata(), with relaxing space usage a bit (around 10+ chars).

Suppose the first 2 of 5 paths are only fit to the threshold, the outputs between the twos are below:

* before the change: `[path1, path2]`
* after the change: `(5 paths)[path1, path2, ...]`

### Why are the changes needed?

SPARK-31793 silently truncates the paths hence end users can't indicate how many paths are truncated, and even more, whether paths are truncated or not.

### Does this PR introduce _any_ user-facing change?

Yes, the location metadata will also show how many paths are truncated (not shown), instead of silently truncated.

### What changes were proposed in this pull request?
Remove the check `verifyAlterTableType()` from the following v1 commands:
- AlterTableAddPartitionCommand
- AlterTableDropPartitionCommand
- AlterTableRenamePartitionCommand
- AlterTableRecoverPartitionsCommand
- AlterTableSerDePropertiesCommand
- AlterTableSetLocationCommand

The check is not needed any more after migration on new resolution framework, see SPARK-29900.

Also new tests were added to:
- AlterTableAddPartitionSuiteBase
- AlterTableDropPartitionSuiteBase
- AlterTableRenamePartitionSuiteBase
- v1/AlterTableRecoverPartitionsSuite

and removed duplicate tests from `SQLViewSuite` and `HiveDDLSuite`.

The tests for `AlterTableSerDePropertiesCommand`/`AlterTableSetLocationCommand` exist in SQLViewSuite` and `HiveDDLSuite`, and they can be ported to unified tests after SPARK-34305 and SPARK-34332.

The `ALTER TABLE .. CHANGE COLUMN` command accepts only tables too, so, the check can be removed after migration on new resolution framework, SPARK-34302.

### Why are the changes needed?
To improve code maintenance by removing dead code.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?

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

This is a followup of https://github.com/apache/spark/pull/31357

#31357 added a very strong restriction to the vectorized parquet reader, that the spark data type must exactly match the physical parquet type, when reading decimal fields. This restriction is actually not necessary, as we can safely read parquet decimals with a larger precision. This PR releases this restriction a little bit.

### Why are the changes needed?

To not fail queries unnecessarily.

### Does this PR introduce _any_ user-facing change?

Yes, now users can read parquet decimals with mismatched `DecimalType` as long as the scale is the same and precision is larger.

This patch proposes to remove `TRUNCATE` from the default `capabilities` list from `FileTable`.

Kousuke Saruta 66f3480f2b [SPARK-34318][SQL] Dataset.colRegex should work with column names and qualifiers which contain newlines
### What changes were proposed in this pull request?

This PR fixes an issue that `Dataset.colRegex` doesn't work with column names or qualifiers which contain newlines.
In the current master, if column names or qualifiers passed to `colRegex` contain newlines, it throws exception.
```
val df = Seq(1, 2, 3).toDF("test\n_column").as("test\n_table")
val col1 = df.colRegex("`tes.*\n.*mn`")
org.apache.spark.sql.AnalysisException: Cannot resolve column name "`tes.*

```

### Why are the changes needed?

Column names and qualifiers can contain newlines but `colRegex` can't work with them, so it's a bug.

### Does this PR introduce _any_ user-facing change?

Yes. users can pass column names and qualifiers even though they contain newlines.

### How was this patch tested?

New test.

Terry Kim f024d3051c [SPARK-34317][SQL] Introduce relationTypeMismatchHint to UnresolvedTable for a better error message
### What changes were proposed in this pull request?

This PR proposes to add `relationTypeMismatchHint` to `UnresolvedTable` so that if a relation is resolved to a view when a table is expected, a hint message can be included as a part of the analysis exception message. Note that the same feature is already introduced to `UnresolvedView` in #30636.

This mostly affects `ALTER TABLE` commands where the analysis exception message will now contain `Please use ALTER VIEW as instead`.

### Why are the changes needed?

To give a better error message. (The hint used to exist but got removed for commands that migrated to the new resolution framework)

### Does this PR introduce _any_ user-facing change?

Yes, now `ALTER TABLE` commands include a hint to use `ALTER VIEW` instead.
```
sql("ALTER TABLE v SET SERDE 'whatever'")
```
Before:
```
"v is a view. 'ALTER TABLE ... SET [SERDE|SERDEPROPERTIES]' expects a table.
```
After this PR:
```
"v is a view. 'ALTER TABLE ... SET [SERDE|SERDEPROPERTIES]' expects a table. Please use ALTER VIEW instead.
```

### How was this patch tested?

Updated existing test cases to include the hint.

Linhong Liu bb9bf66bb6 [SPARK-34199][SQL] Block table.* inside function to follow ANSI standard and other SQL engines
### What changes were proposed in this pull request?
In spark, the `count(table.*)` may cause very weird result, for example:
```
select count(*) from (select 1 as a, null as b) t;
output: 1
select count(t.*) from (select 1 as a, null as b) t;
output: 0
```
 This is because spark expands `t.*` while converts `*` to count(1), this will confuse
users. After checking the ANSI standard, `count(*)` should always be `count(1)` while `count(t.*)`
is not allowed. What's more, this is also not allowed by common databases, e.g. MySQL, Oracle.

So, this PR proposes to block the ambiguous behavior and print a clear error message for users.

### Why are the changes needed?
to avoid ambiguous behavior and follow ANSI standard and other SQL engines

### Does this PR introduce _any_ user-facing change?
Yes, `count(table.*)` behavior will be blocked and output an error message.

### How was this patch tested?
newly added and existing tests

yi.wu e9362c2571 [SPARK-34319][SQL] Resolve duplicate attributes for FlatMapCoGroupsInPandas/MapInPandas
### What changes were proposed in this pull request?

Resolve duplicate attributes for `FlatMapCoGroupsInPandas`.

### Why are the changes needed?

When performing self-join on top of `FlatMapCoGroupsInPandas`, analysis can fail because of conflicting attributes. For example,

```scala
df = spark.createDataFrame([(1, 1)], ("column", "value"))
row = df.groupby("ColUmn").cogroup(
    df.groupby("COLUMN")
).applyInPandas(lambda r, l: r + l, "column long, value long")
row.join(row).show()
```

HyukjinKwon 30468a9015 [SPARK-34306][SQL][PYTHON][R] Use Snake naming rule across the function APIs
### What changes were proposed in this pull request?

This PR completes snake_case rule at functions APIs across the languages, see also SPARK-10621.

In more details, this PR:
- Adds `count_distinct` in Scala Python, and R, and document that `count_distinct` is encouraged. This was not deprecated because `countDistinct` is pretty commonly used. We could deprecate in the future releases.
- (Scala-specific) adds `typedlit` but doesn't deprecate `typedLit` which is arguably commonly used. Likewise, we could deprecate in the future releases.
- Deprecates and renames:
  - `sumDistinct` -> `sum_distinct`
  - `bitwiseNOT` -> `bitwise_not`
  - `shiftLeft` -> `shiftleft` (matched with SQL name in `FunctionRegistry`)
  - `shiftRight` -> `shiftright` (matched with SQL name in `FunctionRegistry`)
  - `shiftRightUnsigned` -> `shiftrightunsigned` (matched with SQL name in `FunctionRegistry`)
  - (Scala-specific) `callUDF` -> `call_udf`

### Why are the changes needed?

To keep the consistent naming in APIs.

### Does this PR introduce _any_ user-facing change?

Yes, it deprecates some APIs and add new renamed APIs as described above.

### How was this patch tested?

Unittests were added.

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

This adds a few test cases for looking up cached temporary/permanent view created using clauses such as `ORDER BY` or `LIMIT`.

### Why are the changes needed?

Due to `EliminateView` and how canonization is done for `View`, which inserts an extra project operator, cache lookup could fail in the following simple example:

Chircu 520e5d2ab8 [SPARK-34144][SQL] Exception thrown when trying to write LocalDate and Instant values to a JDBC relation
### What changes were proposed in this pull request?

When writing rows to a table only the old date time API types are handled in org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils#makeSetter. If the new API is used (spark.sql.datetime.java8API.enabled=true) casting Instant and LocalDate to Timestamp and Date respectively fails. The proposed change is to handle Instant and LocalDate values and transform them to Timestamp and Date.

### Why are the changes needed?

In the current state writing Instant or LocalDate values to a table fails with something like:
Caused by: java.lang.ClassCastException: class java.time.LocalDate cannot be cast to class java.sql.Date (java.time.LocalDate is in module java.base of loader 'bootstrap'; java.sql.Date is in module java.sql of loader 'platform') at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.$anonfun$makeSetter$11(JdbcUtils.scala:573) at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.$anonfun$makeSetter$11$adapted(JdbcUtils.scala:572) at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.savePartition(JdbcUtils.scala:678) at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.$anonfun$saveTable$1(JdbcUtils.scala:858) at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.$anonfun$saveTable$1$adapted(JdbcUtils.scala:856) at org.apache.spark.rdd.RDD.$anonfun$foreachPartition$2(RDD.scala:994) at org.apache.spark.rdd.RDD.$anonfun$foreachPartition$2$adapted(RDD.scala:994) at org.apache.spark.SparkContext.$anonfun$runJob$5(SparkContext.scala:2139) at org.apache.spark.scheduler.ResultTask.runTask(ResultTask.scala:90) at org.apache.spark.scheduler.Task.run(Task.scala:127) at org.apache.spark.executor.Executor$TaskRunner.$anonfun$run$3(Executor.scala:446) at org.apache.spark.util.Utils$.tryWithSafeFinally(Utils.scala:1377) at org.apache.spark.executor.Executor$TaskRunner.run(Executor.scala:449) ... 3 more

Wenchen Fan b891862fb6 [SPARK-34269][SQL] Simplify SQL view resolution
### What changes were proposed in this pull request?

The currently SQL (temp or permanent) view resolution is done in 2 steps:
1. In `SessionCatalog`, we get the view metadata, parse the view SQL string, and wrap it with `View`.
2. At the beginning of the optimizer, we run `EliminateView`, which drops the wrapper `View`, and apply some special logic to match the view schema.

Step 2 is tricky, as we need to retain the output attr expr id, while we need to add an extra `Project` to add cast and alias. This PR simplifies the view solution by building a completed plan (with cast and alias added) in `SessionCatalog`, so that we only have 1 step.

### Why are the changes needed?

Code simplification. It also fixes issues like https://github.com/apache/spark/pull/31352

Cheng Su d871b54a4e [SPARK-34237][SQL] Add more metrics (fallback, spill) to object hash aggregate
### What changes were proposed in this pull request?

This PR is to add two more metrics for `ObjectHashAggregateExec`, i.e. the spill size, and number of fallback to sort-based aggregation.

### Why are the changes needed?

As object hash aggregate fallback mechanism is special - it will fallback to sort-based aggregation based on number of keys seen so far [0]. This fallback logic sometimes is sub-optimal and leads to unnecessary sort, and performance degradation in run-time. The first step to help user/developer debug is to add more related metrics on UI, e.g. spill size, and number of fallback to sort-based aggregation. (spill size metrics was already added for hash aggregate [1])

[0]: https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/ObjectAggregationIterator.scala#L161

[1]: https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/HashAggregateExec.scala#L68

### Does this PR introduce _any_ user-facing change?

Added two more metrics on Spark UI for operator `ObjectHashAggregateExec`. Screenshot is attached below.

### How was this patch tested?

* Added unit test in `SQLMetricsSuite.scala`.
* Tested on spark shell locally and verified the metrics shown up on UI.

Cheng Su 3a361cd837 [SPARK-34253][SQL] Object hash aggregate should not fallback if no more input rows
### What changes were proposed in this pull request?

Object hash aggregate will fallback to sort-based aggregation based on number of keys seen so far [0]. The default config threshold is 128 (spark.sql.objectHashAggregate.sortBased.fallbackThreshold in [1]). There's an edge case we can do better, where we do not fallback if there's no more input rows. Suppose the task only has 128 group-by keys in hash ma, we don't need to fallback in this case, and we can save the extra sort. This is an rare edge case in production, but it can happen.

[0]: https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/aggregate/ObjectAggregationIterator.scala#L161

[1]: https://github.com/apache/spark/blob/master/sql/catalyst/src/main/scala/org/apache/spark/sql/internal/SQLConf.scala#L1615

### Why are the changes needed?

To avoid unnecessary sort in query. Save resource.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Add a unit test to verify task fallback or not is challenging. Given the change is pretty minor, besides relying on existing test in `ObjectHashAggregateSuite.scala`, I manually ran the followed query, and verified in debug mode that the code path for fallback was not executed. And verified the code path for fallback was executed without this change.

```
withSQLConf(
  SQLConf.USE_OBJECT_HASH_AGG.key -> "true",
  SQLConf.OBJECT_AGG_SORT_BASED_FALLBACK_THRESHOLD.key -> "1") {
  Seq.fill(1)(Tuple1(Array.empty[Int]))
    .toDF("c0")
    .groupBy(lit(1))
    .agg(typed_count($"c0"), max($"c0")).collect()
}

MrPowers 9ed0e3cebf [SPARK-34165][SQL] Add count_distinct as an option to Dataset#summary
### What changes were proposed in this pull request?

Add `count_distinct` as an option argument to Dataset#summary (the method already supports count, min, max, etc.)

### Why are the changes needed?

The `summary()` method is used for lightweight exploratory data analysis.  A distinct count of all the columns is one of the most common exploratory data analysis queries.

Distinct counts can be expensive, so this shouldn't be enabled by default.  The proposed implementation is completely backwards compatible.

### Does this PR introduce _any_ user-facing change?

Yes, users can now call `df.summary("count_distinct")`, which wasn't an option before.  Users can still call `df.summary()` without any arguments and the output is the same.  `count_distinct` was not added as one of the `defaultStatistics`.

### How was this patch tested?

Unit tests.

### Additional comments

If this idea is accepted, we should add a PySpark implementation in this PR, as suggested by zero323.

Max Gekk d242166b8f [SPARK-34262][SQL] Refresh cached data of v1 table in ALTER TABLE .. SET LOCATION
### What changes were proposed in this pull request?
Invoke `CatalogImpl.refreshTable()` in v1 implementation of the `ALTER TABLE .. SET LOCATION` command to refresh cached table data.

### Why are the changes needed?
The example below portraits the issue:

- Create a source table:
```sql
spark-sql> CREATE TABLE src_tbl (c0 int, part int) USING hive PARTITIONED BY (part);
spark-sql> INSERT INTO src_tbl PARTITION (part=0) SELECT 0;
spark-sql> SHOW TABLE EXTENDED LIKE 'src_tbl' PARTITION (part=0);
default	src_tbl	false	Partition Values: [part=0]
Location: file:/Users/maximgekk/proj/refresh-cache-set-location/spark-warehouse/src_tbl/part=0
...
```
- Set new location for the empty partition (part=0):
```sql
spark-sql> CREATE TABLE dst_tbl (c0 int, part int) USING hive PARTITIONED BY (part);
spark-sql> ALTER TABLE dst_tbl ADD PARTITION (part=0);
spark-sql> INSERT INTO dst_tbl PARTITION (part=1) SELECT 1;
spark-sql> CACHE TABLE dst_tbl;
spark-sql> SELECT * FROM dst_tbl;
1	1
spark-sql> ALTER TABLE dst_tbl PARTITION (part=0) SET LOCATION '/Users/maximgekk/proj/refresh-cache-set-location/spark-warehouse/src_tbl/part=0';
spark-sql> SELECT * FROM dst_tbl;
1	1
```
The last query does not return new loaded data.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above works correctly:
```sql
spark-sql> ALTER TABLE dst_tbl PARTITION (part=0) SET LOCATION '/Users/maximgekk/proj/refresh-cache-set-location/spark-warehouse/src_tbl/part=0';
spark-sql> SELECT * FROM dst_tbl;
0	0
1	1
```

### How was this patch tested?
Added new test to `org.apache.spark.sql.hive.CachedTableSuite`:
```

```

Chircu 829f118f98 [SPARK-33867][SQL] Instant and LocalDate values aren't handled when generating SQL queries
### What changes were proposed in this pull request?

When generating SQL queries only the old date time API types are handled for values in org.apache.spark.sql.jdbc.JdbcDialect#compileValue. If the new API is used (spark.sql.datetime.java8API.enabled=true) Instant and LocalDate values are not quoted and errors are thrown. The change proposed is to handle Instant and LocalDate values the same way that Timestamp and Date are.

Kent Yao 5718d64f31 [SPARK-34083][SQL] Using TPCDS original definitions for char/varchar columns
### What changes were proposed in this pull request?

This PR changes the column types in the table definitions of `TPCDSBase` from string to char and varchar, with respect to the original definitions for char/varchar columns in the official doc - [TPC-DS_v2.9.0](http://www.tpc.org/tpc_documents_current_versions/pdf/tpc-ds_v2.9.0.pdf).

### Why are the changes needed?

Comply with both TPCDS standard and ANSI, and using string will get wrong results with those TPCDS queries

### Does this PR introduce _any_ user-facing change?

no

### How was this patch tested?

Max Gekk 0d08e22bc7 [SPARK-34251][SQL] Fix table stats calculation by TRUNCATE TABLE
### What changes were proposed in this pull request?
1. Take into account the SQL config `spark.sql.statistics.size.autoUpdate.enabled` in the `TRUNCATE TABLE` command as other commands do.
2. Re-calculate actual table size in fs. Before the changes, `TRUNCATE TABLE` always sets table size to 0 in stats.

### Why are the changes needed?
This fixes the bug that is demonstrated by the example:
1. Create a partitioned table with 2 non-empty partitions:
```sql
spark-sql> CREATE TABLE tbl (c0 int, part int) PARTITIONED BY (part);
spark-sql> INSERT INTO tbl PARTITION (part=0) SELECT 0;
spark-sql> INSERT INTO tbl PARTITION (part=1) SELECT 1;
spark-sql> ANALYZE TABLE tbl COMPUTE STATISTICS;
spark-sql> DESCRIBE TABLE EXTENDED tbl;
...
Statistics	4 bytes, 2 rows
...
```
2. Truncate only one partition:
```sql
spark-sql> TRUNCATE TABLE tbl PARTITION (part=1);
spark-sql> SELECT * FROM tbl;
0	0
```
3. The table is still non-empty but `TRUNCATE TABLE` reseted stats:
```
spark-sql> DESCRIBE TABLE EXTENDED tbl;
...
Statistics	0 bytes, 0 rows
...
```

### Does this PR introduce _any_ user-facing change?
It could impact on performance of following queries.

### How was this patch tested?
Added new test to `StatisticsCollectionSuite`:
```
$ build/sbt -Phive -Phive-thriftserver "test:testOnly *StatisticsCollectionSuite"
$ build/sbt -Phive -Phive-thriftserver "test:testOnly *StatisticsSuite"
```

Kent Yao 91ca21d700 [SPARK-34236][SQL] Fix v2 Overwrite w/ null static partition raise Cannot translate expression to source filter: null
### What changes were proposed in this pull request?

For v2 static partitions overwriting, we use `EqualTo ` to generate the `deleteExpr`

This is not right for null partition values, and cause the problem like below because `ConstantFolding` converts it to lit(null)

```scala
SPARK-34223: static partition with null raise NPE *** FAILED *** (19 milliseconds)

The right way is to use EqualNullSafe instead to delete the null partitions.

Chao Sun abf7e81712 [SPARK-33212][FOLLOW-UP][BUILD] Bring back duplicate dependency check and add more strict Hadoop version check
### What changes were proposed in this pull request?

1. Add back Maven enforcer for duplicate dependencies check
2. More strict check on Hadoop versions which support shaded client in `IsolatedClientLoader`. To do proper version check, this adds a util function `majorMinorPatchVersion` to extract major/minor/patch version from a string.
3. Cleanup unnecessary code

### Why are the changes needed?

The Maven enforcer was removed as part of #30556. This proposes to add it back.

Also, Hadoop shaded client doesn't work in certain cases (see [these comments](https://github.com/apache/spark/pull/30701#discussion_r558522227) for details). This strictly checks that the current Hadoop version (i.e., 3.2.2 at the moment) has good support of shaded client or otherwise fallback to old unshaded ones.

### Does this PR introduce _any_ user-facing change?

No.

### How was this patch tested?

Existing tests.

Dongjoon Hyun dbf051c50a [SPARK-34212][SQL] Fix incorrect decimal reading from Parquet files
### What changes were proposed in this pull request?

This PR aims to the correctness issues during reading decimal values from Parquet files.
- For **MR** code path, `ParquetRowConverter` can read Parquet's decimal values with the original precision and scale written in the corresponding footer.
- For **Vectorized** code path, `VectorizedColumnReader` throws `SchemaColumnConvertNotSupportedException`.

### Why are the changes needed?

Currently, Spark returns incorrect results when the Parquet file's decimal precision and scale are different from the Spark's schema. This happens when there is multiple files with different decimal schema or HiveMetastore has a new schema.

**BEFORE (Simplified example for correctness)**

```scala
scala> sql("SELECT 1.0 a").write.parquet("/tmp/decimal")
scala> spark.read.schema("a DECIMAL(3,2)").parquet("/tmp/decimal").show
+----+
|   a|
+----+
|0.10|
+----+
```

This works correctly in the other data sources, `ORC/JSON/CSV`, like the following.
```scala
scala> sql("SELECT 1.0 a").write.orc("/tmp/decimal_orc")
scala> spark.read.schema("a DECIMAL(3,2)").orc("/tmp/decimal_orc").show
+----+
|   a|
+----+
|1.00|
+----+
```

**AFTER**
1. **Vectorized** path: Instead of incorrect result, we will raise an explicit exception.
```scala
scala> spark.read.schema("a DECIMAL(3,2)").parquet("/tmp/decimal").show
java.lang.UnsupportedOperationException: Schema evolution not supported.
```

2. **MR** path (complex schema or explicit configuration): Spark returns correct results.
```scala
scala> spark.read.schema("a DECIMAL(3,2), b DECIMAL(18, 3), c MAP<INT,INT>").parquet("/tmp/decimal").show
+----+-------+--------+
|   a|      b|       c|
+----+-------+--------+
|1.00|100.000|{1 -> 2}|
+----+-------+--------+

scala> spark.read.schema("a DECIMAL(3,2), b DECIMAL(18, 3), c MAP<INT,INT>").parquet("/tmp/decimal").printSchema
root
 |-- a: decimal(3,2) (nullable = true)
 |-- b: decimal(18,3) (nullable = true)
 |-- c: map (nullable = true)
 |    |-- key: integer
 |    |-- value: integer (valueContainsNull = true)
```

### Does this PR introduce _any_ user-facing change?

Yes. This fixes the correctness issue.

### How was this patch tested?

Pass with the newly added test case.

beliefer 99b6af2dd2 [SPARK-34244][SQL] Remove the Scala function version of regexp_extract_all
### What changes were proposed in this pull request?
https://github.com/apache/spark/pull/27507 implements `regexp_extract_all` and added the scala function version of it.
According https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/functions.scala#L41-L59, it seems good for remove the scala function version. Although I think is regexp_extract_all is very useful, if we just reference the description.

### Why are the changes needed?
`regexp_extract_all` is less common.

### Does this PR introduce _any_ user-facing change?
'No'. `regexp_extract_all` was added in Spark 3.1.0 which isn't released yet.

### How was this patch tested?
Jenkins test.

### What changes were proposed in this pull request?
Invoke `CatalogImpl.refreshTable()` instead of combination of `SessionCatalog.refreshTable()` + `uncacheQuery()`. This allows to clear cached table data while keeping the table cached.

### Why are the changes needed?
1. To improve user experience with Spark SQL
2. To be consistent to other commands, see https://github.com/apache/spark/pull/31206

### Does this PR introduce _any_ user-facing change?
Yes.

Before:
```scala
scala> sql("CREATE TABLE tbl (c0 int)")
res1: org.apache.spark.sql.DataFrame = []
scala> sql("INSERT INTO tbl SELECT 0")
res2: org.apache.spark.sql.DataFrame = []
scala> sql("CACHE TABLE tbl")
res3: org.apache.spark.sql.DataFrame = []
scala> sql("SELECT * FROM tbl").show(false)
+---+
|c0 |
+---+
|0  |

scala> spark.catalog.isCached("tbl")
res5: Boolean = true
scala> sql("TRUNCATE TABLE tbl")
res6: org.apache.spark.sql.DataFrame = []
scala> spark.catalog.isCached("tbl")
res7: Boolean = false
```

After:
```scala
scala> sql("TRUNCATE TABLE tbl")
res6: org.apache.spark.sql.DataFrame = []
scala> spark.catalog.isCached("tbl")
res7: Boolean = true
```

### How was this patch tested?

Kent Yao d1177b5230 [SPARK-34192][SQL] Move char padding to write side and remove length check on read side too
### What changes were proposed in this pull request?

On the read-side, the char length check and padding bring issues to CBO and predicate pushdown and other issues to the catalyst.

This PR reverts 6da5cdf1db  that added read side length check) so that we only do length check for the write side, and data sources/vendors are responsible to enforce the char/varchar constraints for data import operations like ADD PARTITION. It doesn't make sense for Spark to report errors on the read-side if the data is already dirty.

This PR also moves the char padding to the write-side, so that it 1) avoids read side issues like CBO and filter pushdown. 2) the data source can preserve char type semantic better even if it's read by systems other than Spark.

### Why are the changes needed?

fix perf regression when tables have char/varchar type columns

closes #31278
### Does this PR introduce _any_ user-facing change?

yes, spark will not raise error for oversized char/varchar values in read side
### How was this patch tested?

Max Gekk bfc0235013 [SPARK-34203][SQL] Convert null partition values to __HIVE_DEFAULT_PARTITION__ in v1 In-Memory catalog
### What changes were proposed in this pull request?
In the PR, I propose to convert `null` partition values to `"__HIVE_DEFAULT_PARTITION__"` before storing in the `In-Memory` catalog internally. Currently, the `In-Memory` catalog maintains null partitions as `"__HIVE_DEFAULT_PARTITION__"` in file system but as `null` values in memory that could cause some issues like in SPARK-34203.

### Why are the changes needed?
`InMemoryCatalog` stores partitions in the file system in the Hive compatible form, for instance, it converts the `null` partition value to `"__HIVE_DEFAULT_PARTITION__"` but at the same time it keeps null as is internally. That causes an issue demonstrated by the example below:
```
$ ./bin/spark-shell -c spark.sql.catalogImplementation=in-memory
```
```scala
scala> spark.conf.get("spark.sql.catalogImplementation")
res0: String = in-memory

scala> sql("CREATE TABLE tbl (col1 INT, p1 STRING) USING parquet PARTITIONED BY (p1)")
res1: org.apache.spark.sql.DataFrame = []

scala> sql("INSERT OVERWRITE TABLE tbl VALUES (0, null)")
res2: org.apache.spark.sql.DataFrame = []

scala> sql("ALTER TABLE tbl DROP PARTITION (p1 = null)")
org.apache.spark.sql.catalyst.analysis.NoSuchPartitionsException: The following partitions not found in table 'tbl' database 'default':
Map(p1 -> null)
  at org.apache.spark.sql.catalyst.catalog.InMemoryCatalog.dropPartitions(InMemoryCatalog.scala:440)
```

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, `ALTER TABLE .. DROP PARTITION` can drop the `null` partition in `In-Memory` catalog:
```scala
scala> spark.table("tbl").show(false)
+----+----+
|col1|p1  |
+----+----+
|0   |null|
+----+----+

scala> sql("ALTER TABLE tbl DROP PARTITION (p1 = null)")
res4: org.apache.spark.sql.DataFrame = []

scala> spark.table("tbl").show(false)
+----+---+
|col1|p1 |
+----+---+
+----+---+
```

### How was this patch tested?
Added new test to `AlterTableDropPartitionSuiteBase`:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *AlterTableDropPartitionSuite"
```

Max Gekk 6fe5a8a2ae [SPARK-34197][SQL] SessionCatalog.refreshTable() should not invalidate the relation cache for temporary views
### What changes were proposed in this pull request?
Check the name passed to `SessionCatalog.refreshTable`, and if it belongs to a temporary view, do not invalidate the relation cache.

### Why are the changes needed?
When `SessionCatalog.refreshTable` refreshes a temporary or global temporary view, it should not invalidate an entry in the relation cache associated to a table with the same name.

### Does this PR introduce _any_ user-facing change?
Should not. The change might improve performance slightly.

### How was this patch tested?
By running new UT:
```
$ build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *SessionCatalogSuite"
```

yliou 512cacf7c6 [SPARK-33726][SQL] Fix for Duplicate field names during Aggregation
### What changes were proposed in this pull request?
The `RowBasedKeyValueBatch` has two different implementations depending on whether the aggregation key and value uses only fixed length data types (`FixedLengthRowBasedKeyValueBatch`) or not (`VariableLengthRowBasedKeyValueBatch`).

Before this PR the decision about the used implementation was based on by accessing the schema fields by their name.
But if two fields has the same name and one with variable length and the other with fixed length type (and all the other fields are with fixed length types) a bad decision could be made.

When `FixedLengthRowBasedKeyValueBatch` is chosen but there is a variable length field then an aggregation function could calculate with invalid values. This case is illustrated by the example used in the unit test:

`with T as (select id as a, -id as x from range(3)),
        U as (select id as b, cast(id as string) as x from range(3))
select T.x, U.x, min(a) as ma, min(b) as mb from T join U on a=b group by U.x, T.x`
where the 'x' column in the left side of the join is a Long but on the right side is a String.

### Why are the changes needed?
Fixes the issue where duplicate field name aggregation has null values in the dataframe.

### Does this PR introduce _any_ user-facing change?
No

### How was this patch tested?
Added UT, tested manually on spark shell.

Peter Toth 98ec6c27e3 [SPARK-34147][SQL][TEST] Keep table partitioning in TPCDSQueryBenchmak when CBO is enabled
### What changes were proposed in this pull request?
This PR keeps partitioning of input tables in TPCDSQueryBenchmark when `--cbo` option is enabled.

https://github.com/apache/spark/pull/31011 introduced the `--cbo` option but unfortunately in that mode the table partitioning of the input data is lost. This means that the results of CBO mode is very different to non CBO mode, one example is that Dynamic Partition Pruning doesn't kick in in CBO mode.

### Why are the changes needed?
To monitor performance changed with CBO enabled.

### Does this PR introduce _any_ user-facing change?
No.

### How was this patch tested?
Manually checked.

Max Gekk f8bf72ed5d [SPARK-34213][SQL] Refresh cached data of v1 table in LOAD DATA
### What changes were proposed in this pull request?
Invoke `CatalogImpl.refreshTable()` instead of `SessionCatalog.refreshTable` in v1 implementation of the `LOAD DATA` command. `SessionCatalog.refreshTable` just refreshes metadata comparing to `CatalogImpl.refreshTable()` which refreshes cached table data as well.

### Why are the changes needed?
The example below portraits the issue:

- Create a source table:
```sql
spark-sql> CREATE TABLE src_tbl (c0 int, part int) USING hive PARTITIONED BY (part);
spark-sql> INSERT INTO src_tbl PARTITION (part=0) SELECT 0;
spark-sql> SHOW TABLE EXTENDED LIKE 'src_tbl' PARTITION (part=0);
default	src_tbl	false	Partition Values: [part=0]
Location: file:/Users/maximgekk/proj/load-data-refresh-cache/spark-warehouse/src_tbl/part=0
...
```
- Load data from the source table to a cached destination table:
```sql
spark-sql> CREATE TABLE dst_tbl (c0 int, part int) USING hive PARTITIONED BY (part);
spark-sql> INSERT INTO dst_tbl PARTITION (part=1) SELECT 1;
spark-sql> CACHE TABLE dst_tbl;
spark-sql> SELECT * FROM dst_tbl;
1	1
spark-sql> LOAD DATA LOCAL INPATH '/Users/maximgekk/proj/load-data-refresh-cache/spark-warehouse/src_tbl/part=0' INTO TABLE dst_tbl PARTITION (part=0);
spark-sql> SELECT * FROM dst_tbl;
1	1
```
The last query does not return new loaded data.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above works correctly:
```sql
spark-sql> LOAD DATA LOCAL INPATH '/Users/maximgekk/proj/load-data-refresh-cache/spark-warehouse/src_tbl/part=0' INTO TABLE dst_tbl PARTITION (part=0);
spark-sql> SELECT * FROM dst_tbl;
0	0
1	1
```

### How was this patch tested?
Added new test to `org.apache.spark.sql.hive.CachedTableSuite`:
```

Wenchen Fan b8a6906627 [SPARK-34200][SQL] Ambiguous column reference should consider attribute availability
### What changes were proposed in this pull request?

This is a long-standing bug that exists since we have the ambiguous self-join check. A column reference is not ambiguous if it can only come from one join side (e.g. the other side has a project to only pick a few columns). An example is
```
Join(b#1 = 3)
  TableScan(t, [a#0, b#1])
  Project(a#2)
    TableScan(t, [a#2, b#3])
```
It's a self-join, but `b#1` is not ambiguous because it can't come from the right side, which only has column `a`.

### Why are the changes needed?

to not fail valid self-join queries.

### Does this PR introduce _any_ user-facing change?

yea as a bug fix

### How was this patch tested?

a new test

Closes #31287 from cloud-fan/self-join.

Yu Zhong 2db0a954e3 [SPARK-33933][SQL] Materialize BroadcastQueryStage first to try to avoid broadcast timeout in AQE
### What changes were proposed in this pull request?
This PR is the same as https://github.com/apache/spark/pull/30998, but with a better UT.
In AdaptiveSparkPlanExec.getFinalPhysicalPlan, when newStages are generated, sort the new stages by class type to make sure BroadcastQueryState precede others.
This partial fix only grantee the start of materialization for BroadcastQueryStage is prior to others, but because the submission of collect job for broadcasting is run in another thread, the issue is not completely solved.

### Why are the changes needed?
When enable AQE, in getFinalPhysicalPlan, spark traversal the physical plan bottom up and create query stage for materialized part by createQueryStages and materialize those new created query stages to submit map stages or broadcasting. When ShuffleQueryStage are materializing before BroadcastQueryStage, the map stage(job) and broadcast job are submitted almost at the same time, but map stage will hold all the computing resources. If the map stage runs slow (when lots of data needs to process and the resource is limited), the broadcast job cannot be started(and finished) before spark.sql.broadcastTimeout, thus cause whole job failed (introduced in SPARK-31475).
The workaround to increase spark.sql.broadcastTimeout doesn't make sense and graceful, because the data to broadcast is very small.

The order of calling materialize can guarantee that the order of task to be scheduled in normal circumstances, but, the guarantee is not strict since the submit of broadcast job and shuffle map job are in different thread.
1. for broadcast job, call doPrepare() in main thread, and then start the real materialization in "broadcast-exchange-0" thread pool: calling getByteArrayRdd().collect() to submit collect job
2. for shuffle map job, call ShuffleExchangeExec.mapOutputStatisticsFuture() which call sparkContext.submitMapStage() directly in main thread to submit map stage

1 is trigger before 2, so in normal cases, the broadcast job will be submit first.
However, we can not control how fast the two thread runs, so the "broadcast-exchange-0" thread could run a little bit slower than main thread, result in map stage submit first. So there's still risk for the shuffle map job schedule earlier before broadcast job.

Since completely fix the issue is complex and might introduce major changes, we need more time to follow up. This partial fix is better than do nothing, it resolved most cases in SPARK-33933.

### Does this PR introduce _any_ user-facing change?
NO

### How was this patch tested?
Add UT

Closes #31269 from zhongyu09/aqe-broadcast-partial-fix.

beliefer fec82c9504 [SPARK-33245][SQL] Add built-in UDF - GETBIT
### What changes were proposed in this pull request?
`GETBIT` is a bitwise expression function given an INTEGER value, returns the value of a bit at a specified position.
`GETBIT( <integer_expr>, <bit_position> )`

Examples
select getbit(11, 100), getbit(11, 3), getbit(11, 2), getbit(11, 1), getbit(11, 0);
GETBIT(11, 3) | GETBIT(11, 2) | GETBIT(11, 1) | GETBIT(11, 0)
-- | -- | -- | --
1 | 0 | 1 | 1

Kousuke Saruta 45f076336b [SPARK-33813][SQL] Fix the issue that JDBC source can't treat MS SQL Server's spatial types
### What changes were proposed in this pull request?

This PR fixes the issue that reading tables which contain spatial datatypes from MS SQL Server fails.
MS SQL server supports two non-standard spatial JDBC types, `geometry` and  `geography` but Spark SQL can't treat them

```
java.sql.SQLException: Unrecognized SQL type -157
 at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.getCatalystType(JdbcUtils.scala:251)
 at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.$anonfun$getSchema$1(JdbcUtils.scala:321)

 at org.apache.spark.sql.DataFrameReader.load(DataFrameReader.scala:240)
 at org.apache.spark.sql.DataFrameReader.jdbc(DataFrameReader.scala:381)
```

Considering the [data type mapping](https://docs.microsoft.com/ja-jp/sql/connect/jdbc/using-basic-data-types?view=sql-server-ver15) says, I think those spatial types can be mapped to Catalyst's `BinaryType`.

### Why are the changes needed?

To provide better support.

### Does this PR introduce _any_ user-facing change?

Yes. MS SQL Server users can use `geometry` and `geography` types in datasource tables.

### How was this patch tested?

New test case added to `MsSqlServerIntegrationSuite`.

Closes #31283 from sarutak/mssql-spatial-types.
