### What changes were proposed in this pull request?
1. Check that the partition identifier passed to `SupportsPartitionManagement.partitionExists()` is fully specified (specifies all values of partition fields).
2. Remove the custom implementation of `partitionExists()` from `InMemoryPartitionTable`, and re-use the default implementation from `SupportsPartitionManagement`.
### Why are the changes needed?
The method is supposed to check existence of one partition but currently it can return `true` for partially specified partition. This can lead to incorrect commands behavior, for instance the commands could modify or place data in the middle of partition path.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?

### What changes were proposed in this pull request?
This PR adds `allowTemp` flag to `UnresolvedView` so that `Analyzer` can check whether to resolve temp views or not.
This PR also migrates `ALTER VIEW ... SET/UNSET TBLPROPERTIES` to use `UnresolvedView` 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).
### Why are the changes needed?
To use `UnresolvedView` for view resolution.
One benefit is that the exception message is better for `ALTER VIEW ... SET/UNSET TBLPROPERTIES`. Before, if a temp view is passed, you will just get `NoSuchTableException` with `Table or view 'tmpView' not found in database 'default'`. But with this PR, you will get more description exception message: `tmpView is a temp view. ALTER VIEW ... SET TBLPROPERTIES expects a permanent view`.
### Does this PR introduce _any_ user-facing change?
The exception message changes as describe above.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR proposes to migrate `MSCK REPAIR 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 `MSCK REPAIR TABLE` is not supported for v2 tables.
### Why are the changes needed?
The PR makes the resolution consistent behavior consistent. For example,
```scala
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint, val string) USING csv PARTITIONED BY (id)")
sql("CREATE TEMPORARY VIEW t AS SELECT 2")
sql("USE spark_catalog.test")
sql("MSCK REPAIR TABLE t") // works fine
```
, but after this PR:
```
sql("MSCK REPAIR TABLE t")
org.apache.spark.sql.AnalysisException: t is a temp view. 'MSCK REPAIR TABLE' expects a table; line 1 pos 0
```
, which is the consistent behavior with other commands.
### Does this PR introduce _any_ user-facing change?
After this PR, `MSCK REPAIR TABLE t` in the above example is resolved to a temp view `t` first instead of `spark_catalog.test.t`.
### How was this patch tested?

### What changes were proposed in this pull request?
Currently, Spark treats 0.0 and -0.0 semantically equal, while it still retains the difference between them so that users can see -0.0 when displaying the data set.
The comparison expressions in Spark take care of the special floating numbers and implement the correct semantic. However, Spark doesn't always use these comparison expressions to compare values, and we need to normalize the special floating numbers before comparing them in these places:
1. GROUP BY
2. join keys
3. window partition keys

This patch proposes to introduce state schema validation, via storing key schema and value schema to `schema` file (for the first time) and verify new key schema and value schema for state are compatible with existing one. To be clear for definition of "compatible", state schema is "compatible" when number of fields are same and data type for each field is same - Spark has been allowing rename of field.
This patch will prevent query run which has incompatible state schema, which would reduce the chance to get indeterministic behavior (actually renaming of field is also the smell of semantically incompatible, but end users could just modify its name so we can't say) as well as providing more informative error message.

### What changes were proposed in this pull request?
Currently, in spark, the temp view is saved as its analyzed logical plan, while the permanent view
is kept in HMS with its origin SQL text. As a result, permanent and temporary views have
different behaviors in some cases. In this PR we store the SQL text for temporary view in order
to unify the behavior between permanent and temporary views.
### Why are the changes needed?

### What changes were proposed in this pull request?
In the PR, I propose to change the order of post-analysis checks for the `ALTER TABLE .. ADD/DROP PARTITION` command, and perform the general check (does the table support partition management at all) before specific checks.
### Why are the changes needed?
The error message for the table which doesn't support partition management can mislead users:
```java
PartitionSpecs are not resolved;;
'AlterTableAddPartition [UnresolvedPartitionSpec(Map(id -> 1),None)], false
+- ResolvedTable org.apache.spark.sql.connector.InMemoryTableCatalog2fd64b11, ns1.ns2.tbl, org.apache.spark.sql.connector.InMemoryTable5d3ff859
```
because it says nothing about the root cause of the issue.
### Does this PR introduce _any_ user-facing change?
Yes. After the change, the error message will be:
```
Table ns1.ns2.tbl can not alter partitions
```
### How was this patch tested?

### What changes were proposed in this pull request?
This PR provides us with a way to check if a data source is going to reject the delete via `deleteWhere` at planning time.
### Why are the changes needed?
The only way to support delete statements right now is to implement ``SupportsDelete``. According to its Javadoc, that interface is meant for cases when we can delete data without much effort (e.g. like deleting a complete partition in a Hive table).
This PR actually provides us with a way to check if a data source is going to reject the delete via `deleteWhere` at planning time instead of just getting an exception during execution. In the future, we can use this functionality to decide whether Spark should rewrite this delete and execute a distributed query or it can just pass a set of filters.
Consider an example of a partitioned Hive table. If we have a delete predicate like `part_col = '2020'`, we can just drop the matching partition to satisfy this delete. In this case, the data source should return `true` from `canDeleteWhere` and use the filters it accepts in `deleteWhere` to drop the partition. I consider this as a delete without significant effort. At the same time, if we have a delete predicate like `id = 10`, Hive tables would not be able to execute this delete using a metadata only operation without rewriting files. In that case, the data source should return `false` from `canDeleteWhere` and we should use a more sophisticated row-level API to find out which records should be removed (the API is yet to be discussed, but we need this PR as a basis).
If we decide to support subqueries and all delete use cases by simply extending the existing API, this will mean all data sources will have to implement a lot of Spark logic to determine which records changed. I don't think we want to go that way as the Spark logic to determine which records should be deleted is independent of the underlying data source. So the assumption is that Spark will execute a plan to find which records must be deleted for data sources that return `false` from `canDeleteWhere`.
### Does this PR introduce _any_ user-facing change?
Yes but it is backward compatible.
### How was this patch tested?

### What changes were proposed in this pull request?
For CRETE TABLE [AS SELECT] command, creates native Parquet table if neither USING nor STORE AS is specified and `spark.sql.legacy.createHiveTableByDefault` is false.
This is a retry after we unify the CREATE TABLE syntax. It partially reverts d2bec5e265
This PR allows `CREATE EXTERNAL TABLE` when `LOCATION` is present. This was not allowed for data source tables before, which is an unnecessary behavior different with hive tables.
### Why are the changes needed?
Changing from Hive text table to native Parquet table has many benefits:
1. be consistent with `DataFrameWriter.saveAsTable`.
2. better performance
3. better support for nested types (Hive text table doesn't work well with nested types, e.g. `insert into t values struct(null)` actually inserts a null value not `struct(null)` if `t` is a Hive text table, which leads to wrong result)
4. better interoperability as Parquet is a more popular open file format.
### Does this PR introduce _any_ user-facing change?
No by default. If the config is set, the behavior change is described below:
Behavior-wise, the change is very small as the native Parquet table is also Hive-compatible. All the Spark DDL commands that works for hive tables also works for native Parquet tables, with two exceptions: `ALTER TABLE SET [SERDE | SERDEPROPERTIES]` and `LOAD DATA`.
char/varchar behavior has been taken care by https://github.com/apache/spark/pull/30412, and there is no behavior difference between data source and hive tables.
One potential issue is `CREATE TABLE ... LOCATION ...` while users want to directly access the files later. It's more like a corner case and the legacy config should be good enough.
Another potential issue is users may use Spark to create the table and then use Hive to add partitions with different serde. This is not allowed for Spark native tables.

### What changes were proposed in this pull request?
Add new functions DATE_FROM_UNIX_DATE and UNIX_DATE for conversion between Date type and Numeric types.
### Why are the changes needed?
1. Explicit conversion between Date type and Numeric types is disallowed in ANSI mode. We need to provide new functions for users to complete the conversion.
2. We have introduced new functions from Bigquery for conversion between Timestamp type and Numeric types: TIMESTAMP_SECONDS, TIMESTAMP_MILLIS, TIMESTAMP_MICROS , UNIX_SECONDS, UNIX_MILLIS, and UNIX_MICROS. It makes sense to add functions for conversion between Date type and Numeric types as well.
### Does this PR introduce _any_ user-facing change?
Yes, two new datetime functions are added.
### How was this patch tested?

### What changes were proposed in this pull request?
As https://github.com/apache/spark/pull/28534 adds functions from [BigQuery](https://cloud.google.com/bigquery/docs/reference/standard-sql/timestamp_functions) for converting numbers to timestamp, this PR is to add functions UNIX_SECONDS, UNIX_MILLIS and UNIX_MICROS for converting timestamp to numbers.
### Why are the changes needed?
1. Symmetry of the conversion functions
2. Casting timestamp type to numeric types is disallowed in ANSI mode, we should provide functions for users to complete the conversion.
### Does this PR introduce _any_ user-facing change?
3 new functions UNIX_SECONDS, UNIX_MILLIS and UNIX_MICROS for converting timestamp to long type.
### How was this patch tested?

### What changes were proposed in this pull request?
Currently, `join()` uses `withPlan(logicalPlan)` for convenient to call some Dataset functions. But it leads to the `dataset_id` inconsistent between the `logicalPlan` and the original `Dataset`(because `withPlan(logicalPlan)` will create a new Dataset with the new id and reset the `dataset_id` with the new id of the `logicalPlan`). As a result, it breaks the rule `DetectAmbiguousSelfJoin`.
In this PR, we propose to drop the usage of `withPlan` but use the `logicalPlan` directly so its `dataset_id` doesn't change.
Besides, this PR also removes related metadata (`DATASET_ID_KEY`, `COL_POS_KEY`) when an `Alias` tries to construct its own metadata. Because the `Alias` is no longer a reference column after converting to an `Attribute`. To achieve that, we add a new field, `deniedMetadataKeys`, to indicate the metadata that needs to be removed.
### Why are the changes needed?
For the query below, it returns the wrong result while it should throws ambiguous self join exception instead:
```scala
val emp1 = Seq[TestData](
TestData(1, "sales"),
TestData(2, "personnel"),
TestData(3, "develop"),
TestData(4, "IT")).toDS()
val emp2 = Seq[TestData](
TestData(1, "sales"),
TestData(2, "personnel"),
TestData(3, "develop")).toDS()
val emp3 = emp1.join(emp2, emp1("key") === emp2("key")).select(emp1("*"))
emp1.join(emp3, emp1.col("key") === emp3.col("key"), "left_outer")
.select(emp1.col("*"), emp3.col("key").as("e2")).show()
// wrong result
+---+---------+---+
|key| value| e2|
+---+---------+---+
| 1| sales| 1|
| 2|personnel| 2|
| 3| develop| 3|
| 4| IT| 4|
+---+---------+---+
```
This PR fixes the wrong behaviour.
### Does this PR introduce _any_ user-facing change?
Yes, users hit the exception instead of the wrong result after this PR.
### How was this patch tested?

### What changes were proposed in this pull request?
Code Gen bug fix that introduced by SPARK-33460
```
GetMapValueUtil
s"""throw new NoSuchElementException("Key " + $eval2 + " does not exist.");"""
SHOULD BE
s"""throw new java.util.NoSuchElementException("Key " + $eval2 + " does not exist.");"""
```
And the reason why SPARK-33460 failed to detect this bug via UT, it was because that `checkExceptionInExpression ` did not work as expect like `checkEvaluation` which will try eval expression with BOTH `CODEGEN_ONLY` and `NO_CODEGEN` mode, and in this PR, will also fix this Test bug, too.

### What changes were proposed in this pull request?
This PR is a followup of https://github.com/apache/spark/pull/30504. It proposes:
- Rename `NoSideEffect` to `NoThrow`, and use `Expression.deterministic` together where it is used.
- Clarify, in the docs in the expressions, that it means they don't throw exceptions
### Why are the changes needed?
`NoSideEffect` virtually means that `Expression.eval` does not throw an exception, and the expressions are deterministic.
It's best to be explicit so `NoThrow` was proposed - I looked if there's a similar name to represent this concept and borrowed the name of [nothrow](https://clang.llvm.org/docs/AttributeReference.html#nothrow).
For determinism, we already have a way to note it under `Expression.deterministic`.
### Does this PR introduce _any_ user-facing change?
No

### What changes were proposed in this pull request?
This PR is to add full outer stream-stream join, and the implementation of full outer join is:
* For left side input row, check if there's a match on right side state store.
* if there's a match, output the joined row, o.w. output nothing. Put the row in left side state store.
* For right side input row, check if there's a match on left side state store.
* if there's a match, output the joined row, o.w. output nothing. Put the row in right side state store.
* State store eviction: evict rows from left/right side state store below watermark, and output rows never matched before (a combination of left outer and right outer join).
### Why are the changes needed?

### What changes were proposed in this pull request?
https://issues.apache.org/jira/browse/SPARK-32295 added in an optimization to insert a filter for not null and size > 0 when using inner explode/inline. This is fine in most cases but the extra filter is not needed if the explode is with a create array and not using Literals (it already handles LIterals). When this happens you know that the values aren't null and it has a size. It already handles the empty array.
The not null check is already optimized out because Createarray and createMap are not nullable, that leaves the size > 0 check. To handle that this PR makes it so that the size > 0 check gets optimized in ConstantFolding to be the size of the children in the array or map. That makes it a literal and then makes it ultimately be optimized out.
### Why are the changes needed?
remove unneeded filter

### What changes were proposed in this pull request?
This PR adds a new batch to the optimizer for executing rules that rewrite plans for data sources.
### Why are the changes needed?
Right now, we have a special place in the optimizer where we construct v2 scans. As time shows, we need more rewrite rules that would be executed after the operator optimization and before any stats-related rules for v2 tables. Not all rules will be specific to reads. One option is to rename the current batch into something more generic but it would require changing quite some places. That's why it seems better to introduce a new batch and use it for all rewrites. The name is generic so that we don't limit ourselves to v2 data sources only.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
The change is trivial and SPARK-23889 will depend on it.

### What changes were proposed in this pull request?
Spark already support `LIKE ANY` syntax, but it will throw `StackOverflowError` if there are many elements(more than 14378 elements). We should implement built-in function for LIKE ANY to fix this issue.
Why the stack overflow can happen in the current approach ?
The current approach uses reduceLeft to connect each `Like(e, p)`, this will lead the the call depth of the thread is too large, causing `StackOverflowError` problems.
Why the fix in this PR can avoid the error?
This PR support built-in function for `LIKE ANY` and avoid this issue.
### Why are the changes needed?
1.Fix the `StackOverflowError` issue.
2.Support built-in function `like_any`.

### 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`
