### What changes were proposed in this pull request?
Deprecated `KafkaConsumer.poll(long)` API calls may cause infinite wait in the driver. In this PR I've added a new `AdminClient` based offset fetching which is turned off by default. There is a new flag named `spark.sql.streaming.kafka.useDeprecatedOffsetFetching` (default: `true`) which can be set to `false` to reach the newly added functionality. The Structured Streaming migration guide contains more information what migration consideration must be done. Please see the following [doc](https://docs.google.com/document/d/1gAh0pKgZUgyqO2Re3sAy-fdYpe_SxpJ6DkeXE8R1P7E/edit?usp=sharing) for further details.
The PR contains the following changes:
* Added `AdminClient` based offset fetching
* GroupId prefix feature removed from driver but only in `AdminClient` based approach (`AdminClient` doesn't need any GroupId)
* GroupId override feature removed from driver but only in `AdminClient` based approach (`AdminClient` doesn't need any GroupId)
* Additional unit tests
* Code comment changes
* Minor bugfixes here and there
* Removed Kafka auto topic creation feature but only in `AdminClient` based approach (please see doc for rationale). In short, it's super hidden, not sure anybody ever used in production + error prone.
* Added documentation to `ss-migration-guide` and `structured-streaming-kafka-integration`
### Why are the changes needed?

### What changes were proposed in this pull request?
This patch proposes to provide a new option to specify time-to-live (TTL) for output file entries in FileStreamSink. TTL is defined via current timestamp - the last modified time for the file.
This patch will filter out outdated output files in metadata while compacting batches (other batches don't have functionality to clean entries), which helps metadata to not grow linearly, as well as filtered out files will be "eventually" no longer seen in reader queries which leverage File(Stream)Source.
### Why are the changes needed?
The metadata log greatly helps to easily achieve exactly-once but given the output path is open to arbitrary readers, there's no way to compact the metadata log, which ends up growing the metadata file as query runs for long time, especially for compacted batch.
Lots of end users have been reporting the issue: see comments in [SPARK-24295](https://issues.apache.org/jira/browse/SPARK-24295) and [SPARK-29995](https://issues.apache.org/jira/browse/SPARK-29995), and [SPARK-30462](https://issues.apache.org/jira/browse/SPARK-30462).
(There're some reports from end users which include their workarounds: SPARK-24295)
### Does this PR introduce any user-facing change?
No, as the configuration is new and by default it is not applied.
### How was this patch tested?

### What changes were proposed in this pull request?
This patch addresses the case where compact metadata file is read twice in FileStreamSource during restarting query.
When restarting the query, there is a case which the query starts from compaction batch, and the batch has source metadata file to read. One case is that the previous query succeeded to read from inputs, but not finalized the batch for various reasons.
The patch finds the latest compaction batch when restoring from metadata log, and put entries for the batch into the file entry cache which would avoid reading compact batch file twice.
FileStreamSourceLog doesn't know about offset / commit metadata in checkpoint so doesn't know which exactly batch to start from, but in practice, only couple of latest batches are candidates to
be started from when restarting query. This patch leverages the fact to skip calculation if possible.
### Why are the changes needed?
Spark incurs unnecessary cost on reading the compact metadata file twice on some case, which may not be ignorable when the query has been processed huge number of files so far.
### Does this PR introduce any user-facing change?
No.

### What changes were proposed in this pull request?
1. Remove the method `listPartitionIdentifiers()` from the `SupportsPartitionManagement` interface. The method lists partitions by ident prefix.
2. Rename `listPartitionByNames()` to `listPartitionIdentifiers()`.
3. Re-implement the default method `partitionExists()` using new method.
### Why are the changes needed?
Getting partitions by ident prefix only is not used, and it can be removed to improve code maintenance. Also this makes the `SupportsPartitionManagement` interface cleaner.

### What changes were proposed in this pull request?
This PR adds the char/varchar type which is kind of a variant of string type:
1. Char type is fixed-length string. When comparing char type values, we need to pad the shorter one to the longer length.
2. Varchar type is string with a length limitation.
To implement the char/varchar semantic, this PR:
1. Do string length check when writing to char/varchar type columns.
2. Do string padding when reading char type columns. We don't do it at the writing side to save storage space.
3. Do string padding when comparing char type column with string literal or another char type column. (string literal is fixed length so should be treated as char type as well)
To simplify the implementation, this PR doesn't propagate char/varchar type info through functions/operators(e.g. `substring`). That said, a column can only be char/varchar type if it's a table column, not a derived column like `SELECT substring(col)`.
To be safe, this PR doesn't add char/varchar type to the query engine(expression input check, internal row framework, codegen framework, etc.). We will replace char/varchar type by string type with metadata (`Attribute.metadata` or `StructField.metadata`) that includes the original type string before it goes into the query engine. That said, the existing code will not see char/varchar type but only string type.
char/varchar type may come from several places:
1. v1 table from hive catalog.
2. v2 table from v2 catalog.
3. user-specified schema in `spark.read.schema` and `spark.readStream.schema`
4. `Column.cast`
5. schema string in places like `from_json`, pandas UDF, etc. These places use SQL parser which replaces char/varchar with string already, even before this PR.
This PR covers all the above cases, implements the length check and padding feature by looking at string type with special metadata.
### Why are the changes needed?
char and varchar are standard SQL types. varchar is widely used in other databases instead of string type.
### Does this PR introduce _any_ user-facing change?
For hive tables: now the table insertion fails if the value exceeds char/varchar length. Previously we truncate the value silently.
For other tables:
1. now char type is allowed.
2. now we have length check when inserting to varchar columns. Previously we write the value as it is.

### What changes were proposed in this pull request?
Currently, Spark allows calls to `count` even for non parameterless aggregate function. For example, the following query actually works:
`SELECT count() FROM tenk1;`
On the other hand, mainstream databases will throw an error.
**Oracle**
`> ORA-00909: invalid number of arguments`
**PgSQL**
`ERROR: count(*) must be used to call a parameterless aggregate function`
**MySQL**
`> 1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')`
### Why are the changes needed?
Fix a bug so that consistent with mainstream databases.
There is an example query output with/without this fix.
`SELECT count() FROM testData;`
The output before this fix:
`0`
The output after this fix:
```

### What changes were proposed in this pull request?
This PR proposes to support `CHACHE/UNCACHE TABLE` commands for v2 tables.
In addtion, this PR proposes to migrate `CACHE/UNCACHE TABLE` to use `UnresolvedTableOrView` 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).
### Why are the changes needed?
To support `CACHE/UNCACHE TABLE` commands for v2 tables.
Note that `CACHE/UNCACHE TABLE` for v1 tables/views go through `SparkSession.table` to resolve identifier, which resolves temp views first, so there is no change in the behavior by moving to the new framework.
### Does this PR introduce _any_ user-facing change?
Yes. Now the user can run `CACHE/UNCACHE TABLE` commands on v2 tables.
### How was this patch tested?

#### JIRA expectations
```
INSERT currently does not support named column lists.
INSERT INTO <table> (col1, col2,…) VALUES( 'val1', 'val2', … )
Note, we assume the column list contains all the column names. Issue an exception if the list is not complete. The column order could be different from the column order defined in the table definition.
```
#### implemetations
In this PR, we add a column list as an optional part to the `INSERT OVERWRITE/INTO` statements:
```
/**
* {{{
* INSERT OVERWRITE TABLE tableIdentifier [partitionSpec [IF NOT EXISTS]]? [identifierList] ...
* INSERT INTO [TABLE] tableIdentifier [partitionSpec] [identifierList] ...
* }}}
*/
```
The column list represents all expected columns with an explicit order that you want to insert to the target table. **Particularly**, we assume the column list contains all the column names in the current implementation, it will fail when the list is incomplete.
In **Analyzer**, we add a code path to resolve the column list in the `ResolveOutputRelation` rule before it is transformed to v1 or v2 command. It will fail here if the list has any field that not belongs to the target table.
Then, for v2 command, e.g. `AppendData`, we use the resolved column list and output of the target table to resolve the output of the source query `ResolveOutputRelation` rule. If the list has duplicated columns, we fail. If the list is not empty but the list size does not match the target table, we fail. If no other exceptions occur, we use the column list to map the output of the source query to the output of the target table. The column list will be set to Nil and it will not hit the rule again after it is resolved.
for v1 command, those all happen in the `PreprocessTableInsertion` rule

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

### What changes were proposed in this pull request?
Perform partition spec normalization in `ShowTablesCommand` according to the table schema before getting partitions from the catalog. The normalization via `PartitioningUtils.normalizePartitionSpec()` adjusts the column names in partition specification, w.r.t. the real partition column names and case sensitivity.
### Why are the changes needed?
Even when `spark.sql.caseSensitive` is `false` which is the default value, v1 `SHOW TABLE EXTENDED` is case sensitive:
```sql
spark-sql> CREATE TABLE tbl1 (price int, qty int, year int, month int)
> USING parquet
> partitioned by (year, month);
spark-sql> INSERT INTO tbl1 PARTITION(year = 2015, month = 1) SELECT 1, 1;
spark-sql> SHOW TABLE EXTENDED LIKE 'tbl1' PARTITION(YEAR = 2015, Month = 1);
Error in query: Partition spec is invalid. The spec (YEAR, Month) must match the partition spec (year, month) defined in table '`default`.`tbl1`';
```
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the `SHOW TABLE EXTENDED` command respects the SQL config. And for example above, it returns correct result:
```sql
spark-sql> SHOW TABLE EXTENDED LIKE 'tbl1' PARTITION(YEAR = 2015, Month = 1);

### What changes were proposed in this pull request?
Currently in Spark one could redefine a window. For instance:
`select count(*) OVER w FROM tenk1 WINDOW w AS (ORDER BY unique1), w AS (ORDER BY unique1);`

`ERROR: window "w" is already defined`

t is a temp view. 'SHOW CREATE TABLE' expects a table or permanent view.
```
Also, if an identifier is not resolved, the following exception message is currently used:
```
Table or view not found: t
```
After this PR, the message will be:
```
Table or permanent view not found for 'SHOW CREATE TABLE': t
```
or
```
Table or view not found for 'ANALYZE TABLE ... FOR COLUMNS ...': t
```
### Why are the changes needed?
To improve the exception message.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
This PR proposes to fix the exception message for `ANALYZE TABLE ... FOR COLUMNS` on temporary views.
The current behavior throws `NoSuchTableException` even if the temporary view exists:
```

### What changes were proposed in this pull request?
There are some differences between Spark CSV, opencsv and commons-csv, the typical case are described in SPARK-33566, When there are both unescaped quotes and unescaped qualifier in value, the results of parsing are different.
The reason for the difference is Spark use `STOP_AT_DELIMITER` as default `UnescapedQuoteHandling` to build `CsvParser` and it not configurable.
On the other hand, opencsv and commons-csv use the parsing mechanism similar to `STOP_AT_CLOSING_QUOTE ` by default.
So this pr make `unescapedQuoteHandling` option configurable to get the same parsing result as opencsv and commons-csv.
### Why are the changes needed?
Make unescapedQuoteHandling option configurable when read CSV to make parsing more flexible。
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
- Pass the Jenkins or GitHub Action

This PR fixes an AQE issue where local shuffle reader, partition coalescing, or skew join optimization can be mistakenly applied to a shuffle introduced by repartition or a regular shuffle that logically replaces a repartition shuffle.
The proposed solution checks for the presence of any repartition shuffle and filters out not applicable optimization rules for the final stage in an AQE plan.

### What changes were proposed in this pull request?
This patch proposes to support subexpression elimination for interpreted predicate.
### Why are the changes needed?
Similar to interpreted projection, there are use cases when codegen predicate is not able to work, e.g. too complex schema, non-codegen expression, etc. When there are frequently occurring expressions (subexpressions) among predicate expression, the performance is quite bad as we need to re-compute same expressions. We should be able to support subexpression elimination for interpreted predicate like interpreted projection.

### What changes were proposed in this pull request?
When using dynamic partition overwrite, each task has its working dir under staging dir like `stagingDir/.spark-staging-{jobId}`, each task commits to `outputPath/.spark-staging-{jobId}/{partitionId}/part-{taskId}-{jobId}{ext}`.
When speculation enable, multiple task attempts would be setup for one task, **they have same task id and they would commit to same file concurrently**. Due to host done or node preemption, the partly-committed files aren't cleaned up, a FileAlreadyExistsException would be raised in this situation, resulting in job failure.
I don't try to change task commit process for dynamic partition overwrite, like adding attempt id to task working dir for each attempts and committing to final output dir via a new outputCommitCoordinator, here is reason:
1. `FileOutputCommitter` already has commit coordinator for each task attempts, we can leverage it rather than build a new one.
2. To say the least, we implement a coordinator solving task attempts commit conflict, suppose a severe case, application master failover, tasks with same attempt id and same task id would commit to same files, the `FileAlreadyExistsException` risk still exists
In this pr, I leverage FileOutputCommitter to solve the problem:
1. when initing a write job description, set `outputPath/.spark-staging-{jobId}` as the output dir
2. each task attempt writes output to `outputPath/.spark-staging-{jobId}/_temporary/${appAttemptId}/_temporary/${taskAttemptId}/{partitionId}/part-{taskId}-{jobId}{ext}`
3. leverage `FileOutputCommitter` coordinator, write job firstly commits output to `outputPath/.spark-staging-{jobId}/{partitionId}`
4. for dynamic partition overwrite, write job finally move `outputPath/.spark-staging-{jobId}/{partitionId}` to `outputPath/{partitionId}`
### Why are the changes needed?
Without this pr, dynamic partition overwrite would fail

No.

### What changes were proposed in this pull request?
1. Add new method `listPartitionByNames` to the `SupportsPartitionManagement` interface. It allows to list partitions by partition names and their values.
2. Implement new method in `InMemoryPartitionTable` which is used in DSv2 tests.
### Why are the changes needed?
Currently, the `SupportsPartitionManagement` interface exposes only `listPartitionIdentifiers` which allows to list partitions by partition values. And it requires to specify all values for partition schema fields in the prefix. This restriction does not allow to list partitions by some of partition names (not all of them).
For example, the table `tableA` is partitioned by two column `year` and `month`
```
CREATE TABLE tableA (price int, year int, month int)
USING _
partitioned by (year, month)
```
and has the following partitions:
```
PARTITION(year = 2015, month = 1)
PARTITION(year = 2015, month = 2)
PARTITION(year = 2016, month = 2)
PARTITION(year = 2016, month = 3)
```
If we want to list all partitions with `month = 2`, we have to specify `year` for **listPartitionIdentifiers()** which not always possible as we don't know all `year` values in advance. New method **listPartitionByNames()** allows to specify partition values only for `month`, and get two partitions:
```
PARTITION(year = 2015, month = 2)
PARTITION(year = 2016, month = 2)
```

### What changes were proposed in this pull request?
Remove SQL configuration spark.sql.legacy.allowCastNumericToTimestamp
### Why are the changes needed?
In the current master branch, there is a new configuration `spark.sql.legacy.allowCastNumericToTimestamp` which controls whether to cast Numeric types to Timestamp or not. The default value is true.
After https://github.com/apache/spark/pull/30260, the type conversion between Timestamp type and Numeric type is disallowed in ANSI mode. So, we don't need to a separate configuration `spark.sql.legacy.allowCastNumericToTimestamp` for disallowing the conversion. Users just need to set `spark.sql.ansi.enabled` for the behavior.
As the configuration is not in any released yet, we should remove the configuration to make things simpler.
### Does this PR introduce _any_ user-facing change?
No, since the configuration is not released yet.

### What changes were proposed in this pull request?
This PR proposes to add the watermark gap information in SS UI page. Please refer below screenshots to see what we'd like to show in UI.
Please note that this PR doesn't plot the watermark value - knowing the gap between actual wall clock and watermark looks more useful than the absolute value.
### Why are the changes needed?
Watermark is the one of major metrics the end users need to track for stateful queries. Watermark defines "when" the output will be emitted for append mode, hence knowing how much gap between wall clock and watermark (input data) is very helpful to make expectation of the output.
### Does this PR introduce _any_ user-facing change?
Yes, SS UI query page will contain the watermark gap information.
### How was this patch tested?
Basic UT added. Manually tested with two queries:
> simple case
You'll see consistent watermark gap with (15 seconds + a) = 10 seconds are from delay in watermark definition, 5 seconds are trigger interval.
```
import org.apache.spark.sql.streaming.Trigger
spark.conf.set("spark.sql.shuffle.partitions", "10")
val query = spark
.readStream
.format("rate")
.option("rowsPerSecond", 1000)
.option("rampUpTime", "10s")
.load()
.selectExpr("timestamp", "mod(value, 100) as mod", "value")
.withWatermark("timestamp", "10 seconds")
.groupBy(window($"timestamp", "1 minute", "10 seconds"), $"mod")
.agg(max("value").as("max_value"), min("value").as("min_value"), avg("value").as("avg_value"))
.writeStream
.format("console")
.trigger(Trigger.ProcessingTime("5 seconds"))
.outputMode("append")
.start()
query.awaitTermination()
```
> complicated case
This randomizes the timestamp, hence producing random watermark gap. This won't be smaller than 15 seconds as I described earlier.
```
import org.apache.spark.sql.streaming.Trigger
spark.conf.set("spark.sql.shuffle.partitions", "10")
val query = spark
.readStream
.format("rate")
.option("rowsPerSecond", 1000)
.option("rampUpTime", "10s")
.load()
.selectExpr("*", "CAST(CAST(timestamp AS BIGINT) - CAST((RAND() * 100000) AS BIGINT) AS TIMESTAMP) AS tsMod")
.selectExpr("tsMod", "mod(value, 100) as mod", "value")
.withWatermark("tsMod", "10 seconds")

### What changes were proposed in this pull request?
This PR proposes to migrate `SHOW COLUMNS` to use `UnresolvedTableOrView` to resolve the table/view 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).
Note that `SHOW COLUMNS` is not yet supported for v2 tables.
### Why are the changes needed?
To use `UnresolvedTableOrView` for table/view resolution. Note that `ShowColumnsCommand` internally resolves to a temp view first, so there is no resolution behavior change with this PR.

### What changes were proposed in this pull request?
This PR proposes to migrate `TRUNCATE TABLE` to use `UnresolvedTable` 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).
Note that `TRUNCATE TABLE` works only with v1 tables, and not supported for v2 tables.
### Why are the changes needed?
The changes allow consistent resolution behavior when resolving the table identifier. For example, the following is the current behavior:
```scala
sql("CREATE TEMPORARY VIEW t AS SELECT 1")
sql("CREATE DATABASE db")
sql("CREATE TABLE t using csv AS SELECT 1")
sql("USE db")
sql("TRUNCATE TABLE t") // Succeeds
```
With this PR, `TRUNCATE TABLE` above fails with the following:
```
org.apache.spark.sql.AnalysisException: t is a temp view not table.; line 1 pos 0
at org.apache.spark.sql.catalyst.analysis.package$AnalysisErrorAt.failAnalysis(package.scala:42)
at org.apache.spark.sql.catalyst.analysis.Analyzer$ResolveTempViews$$anonfun$apply$7.$anonfun$applyOrElse$42(Analyzer.scala:866)
```
, which is expected since temporary view is resolved first and `TRUNCATE TABLE` doesn't support a temporary view.
### Does this PR introduce _any_ user-facing change?
After this PR, `TRUNCATE TABLE` is resolved to a temp view `t` instead of table `db.t` in the above scenario.
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
In the PR, I propose to changes the resolver of partition specs used in V2 `ALTER TABLE .. ADD/DROP PARTITION` (at the moment), and re-use `CAST` in conversion partition values to desired types according to the partition schema.
### Why are the changes needed?
Currently, the resolver of V2 partition specs supports just a few types: 23e9920b39/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/ResolvePartitionSpec.scala (L72), and fails on other types like date/timestamp.

### What changes were proposed in this pull request?
This PR aims the followings.
1. Upgrade from Scala 2.13.3 to 2.13.4 for Apache Spark 3.1
2. Fix exhaustivity issues in both Scala 2.12/2.13 (Scala 2.13.4 requires this for compilation.)
3. Enforce the improved exhaustive check by using the existing Scala 2.13 GitHub Action compilation job.
### Why are the changes needed?
Scala 2.13.4 is a maintenance release for 2.13 line and improves JDK 15 support.
- https://github.com/scala/scala/releases/tag/v2.13.4
Also, it improves exhaustivity check.
- https://github.com/scala/scala/pull/9140 (Check exhaustivity of pattern matches with "if" guards and custom extractors)
- https://github.com/scala/scala/pull/9147 (Check all bindings exhaustively, e.g. tuples components)
### Does this PR introduce _any_ user-facing change?
Yep. Although it's a maintenance version change, it's a Scala version change.
### How was this patch tested?
Pass the CIs and do the manual testing.
- Scala 2.12 CI jobs(GitHub Action/Jenkins UT/Jenkins K8s IT) to check the validity of code change.
- Scala 2.13 Compilation job to check the compilation

### What changes were proposed in this pull request?
https://github.com/apache/spark/pull/30178 provided `OptimizeWindowFunctions` used to transfer `first` to `nth_value`.
If the window frame is `UNBOUNDED PRECEDING AND CURRENT ROW` or `UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING`, `nth_value` has better performance than `first`.
But the `OptimizeWindowFunctions` need to exclude other window frame.

### What changes were proposed in this pull request?
1. Pre-process partition specs in `ResolvePartitionSpec`, and convert partition names according to the partition schema and the SQL config `spark.sql.caseSensitive`. In the PR, I propose to invoke `normalizePartitionSpec` for that. The function is used in DSv1 commands, so, the behavior will be similar to DSv1.
2. Move `normalizePartitionSpec()` from `sql/core/.../datasources/PartitioningUtils` to `sql/catalyst/.../util/PartitioningUtils` to use it in Catalyst's rule `ResolvePartitionSpec`
### Why are the changes needed?
DSv1 commands like `ALTER TABLE .. ADD PARTITION` and `ALTER TABLE .. DROP PARTITION` respect the SQL config `spark.sql.caseSensitive` while resolving partition specs. For example:
```sql
spark-sql> CREATE TABLE tbl1 (id bigint, data string) USING parquet PARTITIONED BY (id);
spark-sql> ALTER TABLE tbl1 ADD PARTITION (ID=1);
spark-sql> SHOW PARTITIONS tbl1;
id=1
```
The same command fails on V2 Table catalog with error:
```
AnalysisException: Partition key ID not exists
```
### Does this PR introduce _any_ user-facing change?
Yes. After the changes, partition spec resolution works as for DSv1 (without the exception showed above).
### How was this patch tested?
By running `AlterTablePartitionV2SQLSuite`.

### What changes were proposed in this pull request?
This PR proposes to improve the exception messages while `UnresolvedTable` is handled based on this suggestion: https://github.com/apache/spark/pull/30321#discussion_r521127001.
Currently, when an identifier is resolved to a view when a table is expected, the following exception message is displayed (e.g., for `COMMENT ON TABLE`):
```
v is a temp view not table.
```
After this PR, the message will be:
```
v is a temp view. 'COMMENT ON TABLE' expects a table.
```
Also, if an identifier is not resolved, the following exception message is currently used:
```
Table not found: t
```
After this PR, the message will be:
```
Table not found for 'COMMENT ON TABLE': t
```
### Why are the changes needed?
To improve the exception message.
### Does this PR introduce _any_ user-facing change?
Yes, the exception message will be changed as described above.

### What changes were proposed in this pull request?
This reverts commit 065f17386d, which is not part of any released version. That is, this is an unreleased feature
### Why are the changes needed?
I like the concept of Trash, but I think this PR might just resolve a very specific issue by introducing a mechanism without a proper design doc. This could make the usage more complex.
I think we need to consider the big picture. Trash directory is an important concept. If we decide to introduce it, we should consider all the code paths of Spark SQL that could delete the data, instead of Truncate only. We also need to consider what is the current behavior if the underlying file system does not provide the API `Trash.moveToAppropriateTrash`. Is the exception good? How about the performance when users are using the object store instead of HDFS? Will it impact the GDPR compliance?
In sum, I think we should not merge the PR https://github.com/apache/spark/pull/29552 without the design doc and implementation plan. That is why I reverted it before the code freeze of Spark 3.1

The last commits to #30341 follows review comment to use `IdentityHashMap`. Because we leverage `IdentityHashMap` to compare keys in reference, we should not convert expression pairs to Scala map before inserting. Scala map compares keys by equality so we will loss keys with different references.

### What changes were proposed in this pull request?
Two new options, _modifiiedBefore_ and _modifiedAfter_, is provided expecting a value in 'YYYY-MM-DDTHH:mm:ss' format. _PartioningAwareFileIndex_ considers these options during the process of checking for files, just before considering applied _PathFilters_ such as `pathGlobFilter.` In order to filter file results, a new PathFilter class was derived for this purpose. General house-keeping around classes extending PathFilter was performed for neatness. It became apparent support was needed to handle multiple potential path filters. Logic was introduced for this purpose and the associated tests written.
### Why are the changes needed?
When loading files from a data source, there can often times be thousands of file within a respective file path. In many cases I've seen, we want to start loading from a folder path and ideally be able to begin loading files having modification dates past a certain point. This would mean out of thousands of potential files, only the ones with modification dates greater than the specified timestamp would be considered. This saves a ton of time automatically and reduces significant complexity managing this in code.
### Does this PR introduce _any_ user-facing change?
This PR introduces an option that can be used with batch-based Spark file data sources. A documentation update was made to reflect an example and usage of the new data source option.
**Example Usages**

`spark.read.format("csv").option("modifiedAfter","2020-06-15T05:00:00").load()`
_Load all CSV files modified before date:_
`spark.read.format("csv").option("modifiedBefore","2020-06-15T05:00:00").load()`
_Load all CSV files modified between two dates:_
`spark.read.format("csv").option("modifiedAfter","2019-01-15T05:00:00").option("modifiedBefore","2020-06-15T05:00:00").load()

This PR fixes the representation to clarify the meaning of "number of rows dropped by watermark" in SS UI page.

`Aggregated Number Of State Rows Dropped By Watermark` says that the dropped rows are from the state, whereas they're not. We say "evicted from the state" for the case, which is "normal" to emit outputs and reduce memory usage of the state.
The metric actually represents the number of "input" rows dropped by watermark, and the meaning of "input" is relative to the "stateful operator". That's a bit confusing as we normally think "input" as "input from source" whereas it's not.

* For specific errors like `groupingIDMismatch` and `groupingColInvalid`, directly use them as name, just like `groupingIDMismatchError` and `groupingColInvalidError`.
* For generic errors like `dataTypeMismatch`,
* if confident with the context, prefix and condition can be added, like `pivotValDataTypeMismatchError`
* if not sure about the context, add a `For` suffix of the specific component that this exception is related to, like `dataTypeMismatchForDeserializerError`

### What changes were proposed in this pull request?
This adds changes in the following places:
- logic to also refresh caches referencing the target table in v2 `AppendDataExec`, `OverwriteByExpressionExec`, `OverwritePartitionsDynamicExec`, as well as their v1 fallbacks `AppendDataExecV1` and `OverwriteByExpressionExecV1`.
- logic to invalidate caches referencing the target table in v2 `ReplaceTableAsSelectExec` and its atomic version `AtomicReplaceTableAsSelectExec`. These are only supported in v2 at the moment though.
In addition to the above, in order to test the v1 write fallback behavior, I extended `InMemoryTableWithV1Fallback` to also support batch reads.
### Why are the changes needed?
Currently in DataSource v2 we don't refresh or invalidate caches referencing the target table when the table content is changed by operations such as append, overwrite, or replace table. This is different from DataSource v1, and could potentially cause data correctness issue if the staled caches are queried later.
### Does this PR introduce _any_ user-facing change?
Yes. Now When a data source v2 is cached (either directly or indirectly), all the relevant caches will be refreshed or invalidated if the table is replaced.
### How was this patch tested?
Added unit tests for the new code path.

### What changes were proposed in this pull request?
Change `CombineLimits` name to `EliminateLimits` and add check if `Limit` child max row <= limit.
### Why are the changes needed?
In Add-hoc scene, we always add limit for the query if user have no special limit value, but not all limit is nesessary.
A general negative example is
```
select count(*) from t limit 100000;
```
It will be great if we can eliminate limit at Spark side.
Also, we make a benchmark for this case
```
runBenchmark("Sort and Limit") {
val N = 100000
val benchmark = new Benchmark("benchmark sort and limit", N)
benchmark.addCase("TakeOrderedAndProject", 3) { _ =>
spark.range(N).toDF("c").repartition(200).sort("c").take(200000)
}
benchmark.addCase("Sort And Limit", 3) { _ =>
withSQLConf("spark.sql.execution.topKSortFallbackThreshold" -> "-1") {
spark.range(N).toDF("c").repartition(200).sort("c").take(200000)
}
}
benchmark.addCase("Sort", 3) { _ =>
spark.range(N).toDF("c").repartition(200).sort("c").collect()
}
benchmark.run()
}
```
and the result is

### What changes were proposed in this pull request?
This PR switched the order for the rule `RemoveRedundantSorts` and `EnsureRequirements` so that `EnsureRequirements` will be invoked before `RemoveRedundantSorts` to avoid IllegalArgumentException when instantiating PartitioningCollection.
### Why are the changes needed?
`RemoveRedundantSorts` rule uses SparkPlan's `outputPartitioning` to check whether a sort node is redundant. Currently, it is added before `EnsureRequirements`. Since `PartitioningCollection` requires left and right partitioning to have the same number of partitions, which is not necessarily true before applying `EnsureRequirements`, the rule can fail with the following exception:
```
IllegalArgumentException: requirement failed: PartitioningCollection requires all of its partitionings have the same numPartitions.
```

### What changes were proposed in this pull request?
This pull request tries to normalize the SortOrder properly to prevent unnecessary sort operators. Currently the sameOrderExpressions are not normalized as part of AliasAwareOutputOrdering.
Example: consider this join of three tables:
"""
|SELECT t2id, t3.id as t3id
|FROM (
| SELECT t1.id as t1id, t2.id as t2id
| FROM t1, t2
| WHERE t1.id = t2.id
|) t12, t3
|WHERE t1id = t3.id
""".
The plan for this looks like:
*(8) Project [t2id#1059L, id#1004L AS t3id#1060L]
+- *(8) SortMergeJoin [t2id#1059L], [id#1004L], Inner
:- *(5) Sort [t2id#1059L ASC NULLS FIRST ], false, 0 <-----------------------------
: +- *(5) Project [id#1000L AS t2id#1059L]
: +- *(5) SortMergeJoin [id#996L], [id#1000L], Inner
: :- *(2) Sort [id#996L ASC NULLS FIRST ], false, 0
: : +- Exchange hashpartitioning(id#996L, 5), true, [id=#1426]
: : +- *(1) Range (0, 10, step=1, splits=2)
: +- *(4) Sort [id#1000L ASC NULLS FIRST ], false, 0
: +- Exchange hashpartitioning(id#1000L, 5), true, [id=#1432]
: +- *(3) Range (0, 20, step=1, splits=2)
+- *(7) Sort [id#1004L ASC NULLS FIRST ], false, 0
+- Exchange hashpartitioning(id#1004L, 5), true, [id=#1443]
+- *(6) Range (0, 30, step=1, splits=2)
In this plan, the marked sort node could have been avoided as the data is already sorted on "t2.id" by the lower SortMergeJoin.
### Why are the changes needed?
To remove unneeded Sort operators.

### What changes were proposed in this pull request?
In section 6.13 of the ANSI SQL standard, there are syntax rules for valid combinations of the source and target data types.
Comparing the ANSI CAST syntax rules with the current default behavior of Spark:
To make Spark's ANSI mode more ANSI SQL Compatible，I propose to disallow the following casting in ANSI mode:
```
TimeStamp <=> Boolean
Date <=> Boolean
Numeric <=> Timestamp
Numeric <=> Date
Numeric <=> Binary
String <=> Array
String <=> Map
String <=> Struct
```
The following castings are considered invalid in ANSI SQL standard, but they are quite straight forward. Let's Allow them for now
```
Numeric <=> Boolean
String <=> Binary
```
### Why are the changes needed?
Better ANSI SQL compliance
### Does this PR introduce _any_ user-facing change?
Yes, the following castings will not be allowed in ANSI mode:
```
TimeStamp <=> Boolean
Date <=> Boolean
Numeric <=> Timestamp
Numeric <=> Date
Numeric <=> Binary
String <=> Array
String <=> Map
String <=> Struct
```

This adds support for metadata columns to DataSourceV2. If a source implements `SupportsMetadataColumns` it must also implement `SupportsPushDownRequiredColumns` to support projecting those columns.
The analyzer is updated to resolve metadata columns from `LogicalPlan.metadataOutput`, and this adds a rule that will add metadata columns to the output of `DataSourceV2Relation` if one is used.
### Why are the changes needed?
This is the solution discussed for exposing additional data in the Kafka source. It is also needed for a generic `MERGE INTO` plan.

### What changes were proposed in this pull request?
This patch proposes to add subexpression elimination for interpreted expression evaluation. Interpreted expression evaluation is used when codegen was not able to work, for example complex schema.
### Why are the changes needed?
Currently we only do subexpression elimination for codegen. For some reasons, we may need to run interpreted expression evaluation. For example, codegen fails to compile and fallbacks to interpreted mode, or complex input/output schema of expressions. It is commonly seen for complex schema from expressions that is possibly caused by the query optimizer too, e.g. SPARK-32945.
We should also support subexpression elimination for interpreted evaluation. That could reduce performance difference when Spark fallbacks from codegen to interpreted expression evaluation, and improve Spark usability.

ZeroDivisionError: division by zero
```
Actually, almost all cases, users only care about `ZeroDivisionError: division by zero`. We don't really have to show the internal stuff in 99% cases.
This PR adds a configuration `spark.sql.execution.pyspark.udf.simplifiedException.enabled` (disabled by default) that hides the internal tracebacks related to Python worker, (de)serialization, etc.
```python
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/.../python/pyspark/sql/dataframe.py", line 427, in show
print(self._jdf.showString(n, 20, vertical))

pyspark.sql.utils.PythonException:
An exception was thrown from Python worker in the executor:
Traceback (most recent call last):
File "<stdin>", line 1, in <lambda>
ZeroDivisionError: division by zero
```
The trackback will be shown from the point when any non-PySpark file is seen in the traceback.
### Why are the changes needed?
Without this configuration. such internal tracebacks are exposed to users directly especially for shall or notebook users in PySpark. 99% cases people don't care about the internal Python worker, (de)serialization and related tracebacks. It just makes the exception more difficult to read. For example, one statement of `x/0` above shows a very long traceback and most of them are unnecessary.
This configuration enables the ability to show simplified tracebacks which users will likely be most interested in.
### Does this PR introduce _any_ user-facing change?
By default, no. It adds one configuration that simplifies the exception message. See the example above.
### How was this patch tested?
Manually tested:
```bash
$ pyspark --conf spark.sql.execution.pyspark.udf.simplifiedException.enabled=true
```
```python
from pyspark.sql.functions import udf; spark.sparkContext.setLogLevel("FATAL"); spark.range(10).select(udf(lambda x: x/0)("id")).collect()
```

### What changes were proposed in this pull request?
This pull request tries to remove unneeded exchanges/sorts by normalizing the output partitioning and sortorder information correctly with respect to aliases.
Example: consider this join of three tables:
|SELECT t2id, t3.id as t3id
|FROM (
| SELECT t1.id as t1id, t2.id as t2id
| FROM t1, t2
| WHERE t1.id = t2.id
|) t12, t3
|WHERE t1id = t3.id
The plan for this looks like:
*(9) Project [t2id#1034L, id#1004L AS t3id#1035L]
+- *(9) SortMergeJoin [t1id#1033L], [id#1004L], Inner
:- *(6) Sort [t1id#1033L ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(t1id#1033L, 5), true, [id=#1343] <------------------------------
: +- *(5) Project [id#996L AS t1id#1033L, id#1000L AS t2id#1034L]
: +- *(5) SortMergeJoin [id#996L], [id#1000L], Inner
: :- *(2) Sort [id#996L ASC NULLS FIRST], false, 0
: : +- Exchange hashpartitioning(id#996L, 5), true, [id=#1329]
: : +- *(1) Range (0, 10, step=1, splits=2)
: +- *(4) Sort [id#1000L ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(id#1000L, 5), true, [id=#1335]
: +- *(3) Range (0, 20, step=1, splits=2)
+- *(8) Sort [id#1004L ASC NULLS FIRST], false, 0
+- Exchange hashpartitioning(id#1004L, 5), true, [id=#1349]
+- *(7) Range (0, 30, step=1, splits=2)
In this plan, the marked exchange could have been avoided as the data is already partitioned on "t1.id". This happens because AliasAwareOutputPartitioning class handles aliases only related to HashPartitioning. This change normalizes all output partitioning based on aliasing happening in Project.
### Why are the changes needed?
To remove unneeded exchanges.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
New UT added.
On TPCDS 1000 scale, this change improves the performance of query 95 from 330 seconds to 170 seconds by removing the extra Exchange.

### What changes were proposed in this pull request?
1. Move `SHOW PARTITIONS` parsing tests to `ShowPartitionsParserSuite`
2. Place Hive tests for `SHOW PARTITIONS` from `HiveCommandSuite` to the base test suite `v1.ShowPartitionsSuiteBase`. This will allow to run the tests w/ and w/o Hive.
The changes follow the approach of https://github.com/apache/spark/pull/30287.
### Why are the changes needed?
- The unification will allow to run common `SHOW PARTITIONS` tests for both DSv1 and Hive DSv1, DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
By running:
- new test suites `build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly *ShowPartitionsSuite"`
- and old one `build/sbt -Phive-2.3 -Phive-thriftserver "test:testOnly org.apache.spark.sql.hive.execution.HiveCommandSuite"`

### What changes were proposed in this pull request?
Throw `NoSuchNamespaceException` in `listTables()` of the custom test catalog `InMemoryTableCatalog` if the passed namespace doesn't exist.
### Why are the changes needed?
1. To align behavior of V2 `InMemoryTableCatalog` to V1 session catalog.
2. To distinguish two situations:
1. A namespace **does exist** but does not contain any tables. In that case, `listTables()` returns empty result.
2. A namespace **does not exist**. `listTables()` throws `NoSuchNamespaceException` in this case.

Yes. For example, `SHOW TABLES` returns empty result before the changes.

### What changes were proposed in this pull request?
This PR makes SQL parser using active SQLConf instead of the one in ctor-parameters.
### Why are the changes needed?
In ANSI mode, schema string parsing should fail if the schema uses ANSI reserved keyword as attribute name:
```scala
spark.conf.set("spark.sql.ansi.enabled", "true")
spark.sql("""select from_json('{"time":"26/10/2015"}', 'time Timestamp', map('timestampFormat', 'dd/MM/yyyy'));""").show
```
output:
> Cannot parse the data type:
> no viable alternative at input 'time'(line 1, pos 0)
>
> == SQL ==
> time Timestamp
> ^^^
But this query may accidentally succeed in certain cases cause the DataType parser sticks to the configs of the first created session in the current thread:
```scala
DataType.fromDDL("time Timestamp")
val newSpark = spark.newSession()
newSpark.conf.set("spark.sql.ansi.enabled", "true")
newSpark.sql("""select from_json('{"time":"26/10/2015"}', 'time Timestamp', map('timestampFormat', 'dd/MM/yyyy'));""").show
```
output:

### What changes were proposed in this pull request?
SparkSession.sql converts a string value to a DataFrame, and the string value should be one single SQL statement ending up w/ or w/o one or more semicolons. e.g.
```sql
scala> spark.sql(" select 2").show
+---+
| 2|
+---+
| 2|
+---+
scala> spark.sql(" select 2;").show
+---+
| 2|
+---+
| 2|
+---+
scala> spark.sql(" select 2;;;;").show
+---+
| 2|
+---+
| 2|
+---+
```
If we put 2 or more statements in, it fails in the parser as expected, e.g.
```sql
scala> spark.sql(" select 2; select 1;").show
org.apache.spark.sql.catalyst.parser.ParseException:
extraneous input 'select' expecting {<EOF>, ';'}(line 1, pos 11)

As a very generic user scenario, users may want to change some settings before they execute
the queries. They may pass a string value like `set spark.sql.abc=2; select 1;` into this API, which creates a confusing gap between the actual effect and the user's expectations.
The user may want the query to be executed with spark.sql.abc=2, but Spark actually treats the whole part of `2; select 1;` as the value of the property 'spark.sql.abc',
e.g.
```
scala> spark.sql("set spark.sql.abc=2; select 1;").show
+-------------+------------+
| key| value|
+-------------+------------+
|spark.sql.abc|2; select 1;|
+-------------+------------+
```
What's more, the SET symbol could digest everything behind it, which makes it unstable from version to version, e.g.

In this PR,
1. make `set spark.sql.abc=2; select 1;` in `SparkSession.sql` fail directly, user should call `.sql` for each statement separately.
2. make the semicolon as the separator of statements, and if users want to use it as part of the property value, shall use quotes too.
### Why are the changes needed?
1. disambiguation for `SparkSession.sql`
2. make semicolon work same both w/ `SET` and other statements
### Does this PR introduce _any_ user-facing change?
yes,
the semicolon works as a separator of statements now, it will be trimmed if it is at the end of the statement and fail the statement if it is in the middle. you need to use quotes if you want it to be part of the property value

### What changes were proposed in this pull request?
This patch proposes to disable the streaming query with possible correctness issue in chained stateful operators. The behavior can be controlled by a SQL config, so if users understand the risk and still want to run the query, they can disable the check.
### Why are the changes needed?
The possible correctness in chained stateful operators in streaming query is not straightforward for users. From users perspective, it will be considered as a Spark bug. It is also possible the worse case, users are not aware of the correctness issue and use wrong results.
A better approach should be to disable such queries and let users choose to run the query if they understand there is such risk, instead of implicitly running the query and let users to find out correctness issue by themselves and report this known to Spark community.
### Does this PR introduce _any_ user-facing change?
Yes. Streaming query with possible correctness issue will be blocked to run, except for users explicitly disable the SQL config.
### How was this patch tested?
Unit test.

### What changes were proposed in this pull request?
This changes `RefreshTableExec` in DSv2 to also invalidate caches with references to the target table to be refreshed. The change itself is similar to what's done in #30211. Note that though, since we currently don't support caching a DSv2 table directly, this doesn't add recache logic as in the DSv1 impl. I marked it as a TODO for now.
### Why are the changes needed?
Currently the behavior in DSv1 and DSv2 is inconsistent w.r.t refreshing table: in DSv1 we invalidate both metadata cache as well as all table caches that are related to the table, but in DSv2 we only do the former. This addresses the issue and make the behavior consistent.
### Does this PR introduce _any_ user-facing change?
Yes, now refreshing a v2 table also invalidate all the related caches.
### How was this patch tested?
Added a new UT.

other spark session uses a different config value.

### What changes were proposed in this pull request?
Add `Greatest` and `Least` check in `Canonicalize`.
### Why are the changes needed?
The children of both `Greatest` and `Least` are order Irrelevant.
Let's say we have `greatest(1, 2)` and `greatest(2, 1)`. We can get the same canonicalized expression in this case.

### What changes were proposed in this pull request?
Make a special case in `ResolveReferences`, which resolves `OverwriteByExpression`'s condition expression based on the table relation instead of the input query.
### Why are the changes needed?
The condition expression is passed to the table implementation at the end, so we should resolve it using table schema. Previously it works because we have a hack in `ResolveReferences` to delay the resolution if `outputResolved == false`. However, this hack doesn't work for tables accepting any schema like https://github.com/delta-io/delta/pull/521 . We may wrongly resolve the delete condition using input query's outout columns which don't match the table column names.

### What changes were proposed in this pull request?
This PR intends to fix the behaviour of query filters in `TPCDSQueryBenchmark`. We can use an option `--query-filter` for selecting TPCDS queries to run, e.g., `--query-filter q6,q8,q13`. But, the current master has a weird behaviour about the option. For example, if we pass `--query-filter q6` so as to run the TPCDS q6 only, `TPCDSQueryBenchmark` runs `q6` and `q6-v2.7` because the `filterQueries` method does not respect the name suffix. So, there is no way now to run the TPCDS q6 only.

### What changes were proposed in this pull request?
This PR proposes to migrate `SHOW CREATE TABLE` to use `UnresolvedTableOrView` 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).
Note that `SHOW CREATE TABLE` works only with a v1 table and a permanent view, and not supported for v2 tables.
### Why are the changes needed?
The changes allow consistent resolution behavior when resolving the table identifier. For example, the following is the current behavior:
```scala
sql("CREATE TEMPORARY VIEW t AS SELECT 1")
sql("CREATE DATABASE db")
sql("CREATE TABLE t (key INT, value STRING) USING hive")
sql("USE db")
sql("SHOW CREATE TABLE t AS SERDE") // Succeeds
```
With this change, `SHOW CREATE TABLE ... AS SERDE` above fails with the following:
```
org.apache.spark.sql.AnalysisException: t is a temp view not table or permanent view.; line 1 pos 0
at org.apache.spark.sql.catalyst.analysis.package$AnalysisErrorAt.failAnalysis(package.scala:42)
at org.apache.spark.sql.catalyst.analysis.Analyzer$ResolveTempViews$$anonfun$apply$7.$anonfun$applyOrElse$43(Analyzer.scala:883)
at scala.Option.map(Option.scala:230)
```
, which is expected since temporary view is resolved first and `SHOW CREATE TABLE ... AS SERDE` doesn't support a temporary view.
Note that there is no behavior change for `SHOW CREATE TABLE` without `AS SERDE` since it was already resolving to a temporary view first. See below for more detail.
### Does this PR introduce _any_ user-facing change?
After this PR, `SHOW CREATE TABLE t AS SERDE` is resolved to a temp view `t` instead of table `db.t` in the above scenario.
Note that there is no behavior change for `SHOW CREATE TABLE` without `AS SERDE`, but the exception message changes from `SHOW CREATE TABLE is not supported on a temporary view` to `t is a temp view not table or permanent view`.
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
In the PR, I propose to gather common `SHOW TABLES` tests into one trait `org.apache.spark.sql.execution.command.ShowTablesSuite`, and put datasource specific tests to the `v1.ShowTablesSuite` and `v2.ShowTablesSuite`. Also tests for parsing `SHOW TABLES` are extracted to `ShowTablesParserSuite`.
### Why are the changes needed?
- The unification will allow to run common `SHOW TABLES` tests for both DSv1 and DSv2
- We can detect missing features and differences between DSv1 and DSv2 implementations.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
By running new test suites:
- `org.apache.spark.sql.execution.command.v1.ShowTablesSuite`
- `org.apache.spark.sql.execution.command.v2.ShowTablesSuite`
- `ShowTablesParserSuite`

### What changes were proposed in this pull request?
The following query produces incorrect results:
```
SELECT date_trunc('minute', '1769-10-17 17:10:02')
```
Spark currently incorrectly returns
```
1769-10-17 17:10:02
```
against the expected return value of
```
1769-10-17 17:10:00
```
**Steps to repro**
Run the following commands in spark-shell:
```
spark.conf.set("spark.sql.session.timeZone", "America/Los_Angeles")
spark.sql("SELECT date_trunc('minute', '1769-10-17 17:10:02')").show()
```
This happens as `truncTimestamp` in package `org.apache.spark.sql.catalyst.util.DateTimeUtils` incorrectly assumes that time zone offsets can never have the granularity of a second and thus does not account for time zone adjustment when truncating the given timestamp to `minute`.
This assumption is currently used when truncating the timestamps to `microsecond, millisecond, second, or minute`.
This PR fixes this issue and always uses time zone knowledge when truncating timestamps regardless of the truncation unit.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Added new tests to `DateTimeUtilsSuite` which previously failed and pass now.

### What changes were proposed in this pull request?
Currently we skip subexpression elimination in branches of conditional expressions including `If`, `CaseWhen`, and `Coalesce`. Actually we can do subexpression elimination for such branches if the subexpression is common across all branches. This patch proposes to support subexpression elimination in branches of conditional expressions.
### Why are the changes needed?
We may miss subexpression elimination chances in branches of conditional expressions. This kind of subexpression is frequently seen. It may be written manually by users or come from query optimizer. For example, project collapsing could embed expressions between two `Project`s and produces conditional expression like:
```
CASE WHEN jsonToStruct(json).a = '1' THEN 1.0 WHEN jsonToStruct(json).a = '2' THEN 2.0 ... ELSE 1.2 END
```
If `jsonToStruct(json)` is time-expensive expression, we don't eliminate the duplication and waste time on running it repeatedly now.

### What changes were proposed in this pull request?
This removes the `sharesHadoopClasses` flag from `IsolatedClientLoader` in Hive module.
### Why are the changes needed?
Currently, when initializing `IsolatedClientLoader`, users can set the `sharesHadoopClasses` flag to decide whether the `HiveClient` created should share Hadoop classes with Spark itself or not. In the latter case, the client will only load Hadoop classes from the Hive dependencies.
There are two reasons to remove this:
1. this feature is currently used in two cases: 1) unit tests, 2) when the Hadoop version defined in Maven can not be found when `spark.sql.hive.metastore.jars` is equal to "maven", which could be very rare.
2. when `sharesHadoopClasses` is false, Spark doesn't really only use Hadoop classes from Hive jars: we also download `hadoop-client` jar and put all the sub-module jars (e.g., `hadoop-common`, `hadoop-hdfs`) together with the Hive jars, and the Hadoop version used by `hadoop-client` is the same version used by Spark itself. As result, we're mixing two versions of Hadoop jars in the classpath, which could potentially cause issues, especially considering that the default Hadoop version is already 3.2.0 while most Hive versions supported by the `IsolatedClientLoader` is still using Hadoop 2.x or even lower.
### Does this PR introduce _any_ user-facing change?
This affects Spark users in one scenario: when `spark.sql.hive.metastore.jars` is set to `maven` AND the Hadoop version specified in pom file cannot be downloaded, currently the behavior is to switch to _not_ share Hadoop classes, but with the PR it will share Hadoop classes with Spark.

### Why are the changes needed?
The code paths of `spark.table` and `spark.read.table` should be the same. This behavior is broke in SPARK-32592 since we need to respect options in `spark.read.table` API.
### Does this PR introduce _any_ user-facing change?
No.

### What changes were proposed in this pull request?
This PR proposes to migrate `LOAD DATA` to use `UnresolvedTable` 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).
Note that `LOAD DATA` is not supported for v2 tables.
### Why are the changes needed?
The changes allow consistent resolution behavior when resolving the table identifier. For example, the following is the current behavior:
```scala
sql("CREATE TEMPORARY VIEW t AS SELECT 1")
sql("CREATE DATABASE db")
sql("CREATE TABLE t (key INT, value STRING) USING hive")
sql("USE db")
sql("LOAD DATA LOCAL INPATH 'examples/src/main/resources/kv1.txt' INTO TABLE t") // Succeeds
```
With this change, `LOAD DATA` above fails with the following:
```
org.apache.spark.sql.AnalysisException: t is a temp view not table.; line 1 pos 0
at org.apache.spark.sql.catalyst.analysis.package$AnalysisErrorAt.failAnalysis(package.scala:42)
at org.apache.spark.sql.catalyst.analysis.Analyzer$ResolveTempViews$$anonfun$apply$7.$anonfun$applyOrElse$39(Analyzer.scala:865)
at scala.Option.foreach(Option.scala:407)
```
, which is expected since temporary view is resolved first and `LOAD DATA` doesn't support a temporary view.
### Does this PR introduce _any_ user-facing change?
After this PR, `LOAD DATA ... t` is resolved to a temp view `t` instead of table `db.t` in the above scenario.
### How was this patch tested?
Updated existing tests.

### What changes were proposed in this pull request?
When TableProvider.supportsExternalMetadata() is true, Spark will use the input Dataframe's schema in `DataframeWriter.save()`/`DataStreamWriter.start()` and skip schema/partitioning inference.
### Why are the changes needed?
For all the v2 data sources which are not FileDataSourceV2, Spark always infers the table schema/partitioning on `DataframeWriter.save()`/`DataStreamWriter.start()`.
The inference of table schema/partitioning can be expensive. However, there is no such trait or flag for indicating a V2 source can use the input DataFrame's schema on `DataframeWriter.save()`/`DataStreamWriter.start()`. We can resolve the problem by adding a new expected behavior for the method `TableProvider.supportsExternalMetadata()`.
### Does this PR introduce _any_ user-facing change?
Yes, a new behavior for the data source v2 API `TableProvider.supportsExternalMetadata()` when it returns true.

### What changes were proposed in this pull request?
This PR makes `DataFrameWriterV2` to create query plans with `UnresolvedRelation` and leave the table resolution work to the analyzer.
### Why are the changes needed?
Table resolution work should be done by the analyzer. After this PR, the behavior is more consistent between different APIs (DataFrameWriter, DataFrameWriterV2 and SQL). See the next section for behavior changes.
### Does this PR introduce _any_ user-facing change?
Yes.
1. writes to a temp view of v2 relation: previously it fails with table not found exception, now it works if the v2 relation is writable. This is consistent with `DataFrameWriter` and SQL INSERT.
2. writes to other temp views: previously it fails with table not found exception, now it fails with a more explicit error message, saying that writing to a temp view of non-v2-relation is not allowed.
3. writes to a view: previously it fails with table not writable error, now it fails with a more explicit error message, saying that writing to a view is not allowed.
4. writes to a v1 table: previously it fails with table not writable error, now it fails with a more explicit error message, saying that writing to a v1 table is not allowed. (We can allow it later, by falling back to v1 command)

### What changes were proposed in this pull request?
The changes in [SPARK-32501 Inconsistent NULL conversions to strings](https://issues.apache.org/jira/browse/SPARK-32501) introduced some behavior that I'd like to clean up a bit.
Here's sample code to illustrate the behavior I'd like to clean up:
```scala
val rows = Seq[String](null)
.toDF("value")
.withColumn("struct1", struct('value as "value1"))
.withColumn("struct2", struct('value as "value1", 'value as "value2"))
.withColumn("array1", array('value))
.withColumn("array2", array('value, 'value))
// Show the DataFrame using the "first" codepath.
rows.show(truncate=false)
+-----+-------+-------------+------+--------+
|value|struct1|struct2 |array1|array2 |
+-----+-------+-------------+------+--------+
|null |{ null}|{ null, null}|[] |[, null]|
+-----+-------+-------------+------+--------+
// Write the DataFrame to disk, then read it back and show it to trigger the "codegen" code path:
rows.write.parquet("rows")
spark.read.parquet("rows").show(truncate=false)
+-----+-------+-------------+-------+-------------+
|value|struct1|struct2 |array1 |array2 |
+-----+-------+-------------+-------+-------------+
|null |{ null}|{ null, null}|[ null]|[ null, null]|
+-----+-------+-------------+-------+-------------+
```
Notice:
1. If the first element of a struct is null, it is printed with a leading space (e.g. "\{ null\}"). I think it's preferable to print it without the leading space (e.g. "\{null\}"). This is consistent with how non-null values are printed inside a struct.
2. If the first element of an array is null, it is not printed at all in the first code path, and the "codegen" code path prints it with a leading space. I think both code paths should be consistent and print it without a leading space (e.g. "[null]").
The desired result of this PR is to product the following output via both code paths:
```
+-----+-------+------------+------+------------+
|value|struct1|struct2 |array1|array2 |
+-----+-------+------------+------+------------+
|null |{null} |{null, null}|[null]|[null, null]|
+-----+-------+------------+------+------------+
```

### What changes were proposed in this pull request?
There's a concept of 'read-only' and 'read+write' state store in Spark which is defined "implicitly". Spark doesn't prevent write for 'read-only' state store; Spark just assumes read-only stateful operator will not modify the state store. Given it's not defined explicitly, the instance of state store has to be implemented as 'read+write' even it's being used as 'read-only', which sometimes brings confusion.
For example, abort() in HDFSBackedStateStore - d38f816748/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/state/HDFSBackedStateStoreProvider.scala (L143-L155)
The comment sounds as if statement works differently between 'read-only' and 'read+write', but that's not true as both state store has state initialized as UPDATING (no difference). So 'read-only' state also creates the temporary file, initializes output streams to write to temporary file, closes output streams, and finally deletes the temporary file. This unnecessary operations are being done per batch/partition.
This patch explicitly defines 'read-only' StateStore, and enables state store provider to create 'read-only' StateStore instance if requested. Relevant code paths are modified, as well as 'read-only' StateStore implementation for HDFSBackedStateStore is introduced. The new implementation gets rid of unnecessary operations explained above.
In point of backward-compatibility view, the only thing being changed in public API side is `StateStoreProvider`. The trait `StateStoreProvider` has to be changed to allow requesting 'read-only' StateStore; this patch adds default implementation which leverages 'read+write' StateStore but wrapping with 'write-protected' StateStore instance, so that custom providers don't need to change their code to reflect the change. But if the providers can optimize for read-only workload, they'll be happy to make a change.
Please note that this patch makes ReadOnlyStateStore extend StateStore and being referred as StateStore, as StateStore is being used in so many places and it's not easy to support both traits if we differentiate them. So unfortunately these write methods are still exposed for read-only state; it just throws UnsupportedOperationException.
### Why are the changes needed?
The new API opens the chance to optimize read-only state store instance compared with read+write state store instance. HDFSBackedStateStoreProvider is modified to provide read-only version of state store which doesn't deal with temporary file as well as state machine.
### Does this PR introduce any user-facing change?
Clearly "no" for most end users, and also "no" for custom state store providers as it doesn't touch trait `StateStore` as well as provides default implementation for added method in trait `StateStoreProvider`.
### How was this patch tested?
Modified UT. Existing UTs ensure the change doesn't break anything.

### What changes were proposed in this pull request?
This PR changes `HiveExternalCatalogVersionsSuite` to, by default, use a standard temporary directory to store the Spark binaries that it localizes. It additionally adds a new System property, `spark.test.cache-dir`, which can be used to define a static location into which the Spark binary will be localized to allow for sharing between test executions. If the System property is used, the downloaded binaries won't be deleted after the test runs.
### Why are the changes needed?
In SPARK-22356 (PR #19579), the `sparkTestingDir` used by `HiveExternalCatalogVersionsSuite` became hard-coded to enable re-use of the downloaded Spark tarball between test executions:
```
// For local test, you can set `sparkTestingDir` to a static value like `/tmp/test-spark`, to
// avoid downloading Spark of different versions in each run.
private val sparkTestingDir = new File("/tmp/test-spark")
```
However this doesn't work, since it gets deleted every time:
```
override def afterAll(): Unit = {
try {
Utils.deleteRecursively(wareHousePath)
Utils.deleteRecursively(tmpDataDir)
Utils.deleteRecursively(sparkTestingDir)
} finally {
super.afterAll()
}
}
```
It's bad that we're hard-coding to a `/tmp` directory, as in some cases this is not the proper place to store temporary files. We're not currently making any good use of it.
### Does this PR introduce _any_ user-facing change?
Developer-facing changes only, as this is in a test.
### How was this patch tested?
The test continues to execute as expected.
