### What changes were proposed in this pull request?
Add AlterNamespaceSetPropertiesStatement, AlterNamespaceSetProperties and AlterNamespaceSetPropertiesExec to make ALTER DATABASE (SET DBPROPERTIES) command look up catalog like v2 commands.
### Why are the changes needed?
It's important to make all the commands have the same catalog/namespace resolution behavior, to avoid confusing end-users.
### Does this PR introduce any user-facing change?
Yes, add "ALTER NAMESPACE ... SET (DBPROPERTIES | PROPERTIES) ..." whose function is same as "ALTER DATABASE ... SET DBPROPERTIES ..." and "ALTER SCHEMA ... SET DBPROPERTIES ...".
### How was this patch tested?

### What changes were proposed in this pull request?
Rename config "spark.sql.ansi.enabled" to "spark.sql.dialect.spark.ansi.enabled"
### Why are the changes needed?
The relation between "spark.sql.ansi.enabled" and "spark.sql.dialect" is confusing, since the "PostgreSQL" dialect should contain the features of "spark.sql.ansi.enabled".
To make things clearer, we can rename the "spark.sql.ansi.enabled" to "spark.sql.dialect.spark.ansi.enabled", thus the option "spark.sql.dialect.spark.ansi.enabled" is only for Spark dialect.
For the casting and arithmetic operations, runtime exceptions should be thrown if "spark.sql.dialect" is "spark" and "spark.sql.dialect.spark.ansi.enabled" is true or "spark.sql.dialect" is PostgresSQL.
### Does this PR introduce any user-facing change?
Yes, the config name changed.

### What changes were proposed in this pull request?
This PR aims to add `io.netty.tryReflectionSetAccessible=true` to the testing configuration for JDK11 because this is an officially documented requirement of Apache Arrow.
Apache Arrow community documented this requirement at `0.15.0` ([ARROW-6206](https://github.com/apache/arrow/pull/5078)).
> #### For java 9 or later, should set "-Dio.netty.tryReflectionSetAccessible=true".
> This fixes `java.lang.UnsupportedOperationException: sun.misc.Unsafe or java.nio.DirectByteBuffer.(long, int) not available`. thrown by netty.
### Why are the changes needed?
After ARROW-3191, Arrow Java library requires the property `io.netty.tryReflectionSetAccessible` to be set to true for JDK >= 9. After https://github.com/apache/spark/pull/26133, JDK11 Jenkins job seem to fail.

This PR proposes to show Python, pandas and PyArrow versions in integrated UDF tests as a clue so when the test cases fail, it show the related version information.

### What changes were proposed in this pull request?
In order to avoid frequently changing the value of `spark.sql.adaptive.shuffle.maxNumPostShufflePartitions`, we usually set `spark.sql.adaptive.shuffle.maxNumPostShufflePartitions` much larger than `spark.sql.shuffle.partitions` after enabling adaptive execution, which causes some bucket map join lose efficacy and add more `ShuffleExchange`.
How to reproduce:
```scala
val bucketedTableName = "bucketed_table"
spark.range(10000).write.bucketBy(500, "id").sortBy("id").mode(org.apache.spark.sql.SaveMode.Overwrite).saveAsTable(bucketedTableName)
val bucketedTable = spark.table(bucketedTableName)
val df = spark.range(8)
spark.conf.set("spark.sql.autoBroadcastJoinThreshold", -1)
// Spark 2.4. spark.sql.adaptive.enabled=false
// We set spark.sql.shuffle.partitions <= 500 every time based on our data in this case.
spark.conf.set("spark.sql.shuffle.partitions", 500)
bucketedTable.join(df, "id").explain()
// Since 3.0. We enabled adaptive execution and set spark.sql.adaptive.shuffle.maxNumPostShufflePartitions to a larger values to fit more cases.
spark.conf.set("spark.sql.adaptive.enabled", true)
spark.conf.set("spark.sql.adaptive.shuffle.maxNumPostShufflePartitions", 1000)
bucketedTable.join(df, "id").explain()
```

### What changes were proposed in this pull request?
This is a followup of https://github.com/apache/spark/pull/23977 I made a mistake related to this line: 3725b1324f (diff-71c2cad03f08cb5f6c70462aa4e28d3aL112)
Previously,
1. the reader iterator for R worker read some initial data eagerly during RDD materialization. So it read the data before actual execution. For some reasons, in this case, it showed standard error from R worker.
2. After that, when error happens during actual execution, stderr wasn't shown: 3725b1324f (diff-71c2cad03f08cb5f6c70462aa4e28d3aL260)
After my change 3725b1324f (diff-71c2cad03f08cb5f6c70462aa4e28d3aL112), it now ignores 1. case and only does 2. of previous code path, because 1. does not happen anymore as I avoided to such eager execution (which is consistent with PySpark code path).
This PR proposes to do only 1. before/after execution always because It is pretty much possible R worker was failed during actual execution and it's best to show the stderr from R worker whenever possible.
### Why are the changes needed?
It currently swallows standard error from R worker which makes debugging harder.
### Does this PR introduce any user-facing change?
Yes,

### What changes were proposed in this pull request?
This PR addresses issues where conflicting attributes in `Expand` are not correctly handled.
### Why are the changes needed?

val cubeDF = numsDF.cube("nums").agg(max(lit(0)).as("agcol"))
cubeDF.join(cubeDF, "nums").show
```
fails with the following exception:
```
org.apache.spark.sql.AnalysisException:

^^^^^^^
+- Project [nums#3, nums#3 AS nums#37]
+- Project [value#1 AS nums#3]
+- LocalRelation [value#1]
Conflicting attributes: nums#38
```
As you can see from the above plan, `num#38`, the output of `Expand` on the right side of `Join`, should have been handled to produce new attribute. Since the conflict is not resolved in `Expand`, the failure is happening upstream at `Aggregate`. This PR addresses handling conflicting attributes in `Expand`.
### Does this PR introduce any user-facing change?
Yes, the previous example now shows the following output:

### What changes were proposed in this pull request?
Make SparkSQL's `cast to boolean` behavior be consistent with PostgreSQL when
spark.sql.dialect is configured as PostgreSQL.
### Why are the changes needed?
SparkSQL and PostgreSQL have a lot different cast behavior between types by default. We should make SparkSQL's cast behavior be consistent with PostgreSQL when `spark.sql.dialect` is configured as PostgreSQL.
### Does this PR introduce any user-facing change?
Yes. If user switches to PostgreSQL dialect now, they will
* get an exception if they input a invalid string, e.g "erut", while they get `null` before;
* get an exception if they input `TimestampType`, `DateType`, `LongType`, `ShortType`, `ByteType`, `DecimalType`, `DoubleType`, `FloatType` values, while they get `true` or `false` result before.
And here're evidences for those unsupported types from PostgreSQL:
timestamp:
```
postgres=# select cast(cast('2019-11-11' as timestamp) as boolean);
ERROR: cannot cast type timestamp without time zone to boolean
```
date:
```
postgres=# select cast(cast('2019-11-11' as date) as boolean);
ERROR: cannot cast type date to boolean
```
bigint:
```
postgres=# select cast(cast('20191111' as bigint) as boolean);
ERROR: cannot cast type bigint to boolean
```
smallint:
```
postgres=# select cast(cast(2019 as smallint) as boolean);
ERROR: cannot cast type smallint to boolean
```
bytea:
```
postgres=# select cast(cast('2019' as bytea) as boolean);
ERROR: cannot cast type bytea to boolean
```
decimal:
```
postgres=# select cast(cast('2019' as decimal) as boolean);
ERROR: cannot cast type numeric to boolean
```
float:
```
postgres=# select cast(cast('2019' as float) as boolean);
ERROR: cannot cast type double precision to boolean
```

### What changes were proposed in this pull request?
We already know task attempts that do not clean up output files in staging directory can cause job failure (SPARK-27194). There was proposals trying to fix it by changing output filename, or deleting existing output files. These proposals are not reliable completely.
The difficulty is, as previous failed task attempt wrote the output file, at next task attempt the output file is still under same staging directory, even the output file name is different.
If the job will go to fail eventually, there is no point to re-run the task until max attempts are reached. For the jobs running a lot of time, re-running the task can waste a lot of time.
This patch proposes to let Spark detect such file already exist exception and stop the task set early.
### Why are the changes needed?
For now, if FileAlreadyExistsException is thrown during data writing job in SQL, the job will continue re-running task attempts until max failure number is reached. It is no point for re-running tasks as task attempts will also fail because they can not write to the existing file too. We should stop the task set early.
### Does this PR introduce any user-facing change?
Yes. If FileAlreadyExistsException is thrown during data writing job in SQL, no more task attempts are re-tried and the task set will be stoped early.
### How was this patch tested?

### What changes were proposed in this pull request?
Corrected ShortType and ByteType mapping to SmallInt and TinyInt, corrected setter methods to set ShortType and ByteType as setShort() and setByte(). Changes in JDBCUtils.scala
Fixed Unit test cases to where applicable and added new E2E test cases in to test table read/write using ShortType and ByteType.
#### Problems
- In master in JDBCUtils.scala line number 547 and 551 have a problem where ShortType and ByteType are set as Integers rather than set as Short and Byte respectively.
```
case ShortType =>
(stmt: PreparedStatement, row: Row, pos: Int) =>
stmt.setInt(pos + 1, row.getShort(pos))
The issue was pointed out by maropu
case ByteType =>
(stmt: PreparedStatement, row: Row, pos: Int) =>
stmt.setInt(pos + 1, row.getByte(pos))
```
- Also at line JDBCUtils.scala 247 TinyInt is interpreted wrongly as IntergetType in getCatalystType()
``` case java.sql.Types.TINYINT => IntegerType ```
- At line 172 ShortType was wrongly interpreted as IntegerType
``` case ShortType => Option(JdbcType("INTEGER", java.sql.Types.SMALLINT)) ```
- All thru out tests, ShortType and ByteType were being interpreted as IntegerTypes.
### Why are the changes needed?
A given type should be set using the right type.
### Does this PR introduce any user-facing change?
No

### What changes were proposed in this pull request?
This PR adds a SQL Conf: `spark.sql.streaming.stopActiveRunOnRestart`. When this conf is `true` (by default it is), an already running stream will be stopped, if a new copy gets launched on the same checkpoint location.
### Why are the changes needed?
In multi-tenant environments where you have multiple SparkSessions, you can accidentally start multiple copies of the same stream (i.e. streams using the same checkpoint location). This will cause all new instantiations of the new stream to fail. However, sometimes you may want to turn off the old stream, as the old stream may have turned into a zombie (you no longer have access to the query handle or SparkSession).
It would be nice to have a SQL flag that allows the stopping of the old stream for such zombie cases.
### Does this PR introduce any user-facing change?
Yes. Now by default, if you launch a new copy of an already running stream on a multi-tenant cluster, the existing stream will be stopped.
### How was this patch tested?

### Why are the changes needed?
Under ansi mode, `every`, `any` and `some` are reserved keywords and can't be used as function names. `EveryAgg`/`AnyAgg` has several aliases and I think it's better to not pick reserved keywords as the primary name.

### What changes were proposed in this pull request?
The current parse and analyze flow for DELETE is: 1, the SQL string will be firstly parsed to `DeleteFromStatement`; 2, the `DeleteFromStatement` be converted to `DeleteFromTable`. However, the SQL string can be parsed to `DeleteFromTable` directly, where a `DeleteFromStatement` seems to be redundant.
It is the same for UPDATE.
This pr removes the unnecessary `DeleteFromStatement` and `UpdateTableStatement`.

### What changes were proposed in this pull request?
Currently, `SupportsNamespaces.dropNamespace` drops a namespace only if it is empty. Thus, to implement a cascading drop, one needs to iterate all objects (tables, view, etc.) within the namespace (including its sub-namespaces recursively) and drop them one by one. This can have a negative impact on the performance when there are large number of objects.
Instead, this PR proposes to change the default behavior of dropping a namespace to cascading such that implementing cascading/non-cascading drop is simpler without performance penalties.
### Why are the changes needed?
The new behavior makes implementing cascading/non-cascading drop simple without performance penalties.
### Does this PR introduce any user-facing change?
Yes. The default behavior of `SupportsNamespaces.dropNamespace` is now cascading.

### What changes were proposed in this pull request?
When creating v2 expressions, we have public java APIs, as well as interval scala APIs. All of these APIs take a string column name and parse it to `NamedReference`.
This is convenient for end-users, but not for interval development. For example, the query plan already contains the parsed partition/bucket column names, and it's tricky if we need to quote the names before creating v2 expressions.
This PR proposes to change the interval scala APIs to take `NamedReference` directly, with a new method to create `NamedReference` with the exact name parts. The public java APIs are not changed.
### Why are the changes needed?

### What changes were proposed in this pull request?
This patch fixes the edge case of streaming left/right outer join described below:
Suppose query is provided as
`select * from A join B on A.id = B.id AND (A.ts <= B.ts AND B.ts <= A.ts + interval 5 seconds)`
and there're two rows for L1 (from A) and R1 (from B) which ensures L1.id = R1.id and L1.ts = R1.ts.
(we can simply imagine it from self-join)
Then Spark processes L1 and R1 as below:
- row L1 and row R1 are joined at batch 1
- row R1 is evicted at batch 2 due to join and watermark condition, whereas row L1 is not evicted
- row L1 is evicted at batch 3 due to join and watermark condition
When determining outer rows to match with null, Spark applies some assumption commented in codebase, as below:
```
Checking whether the current row matches a key in the right side state, and that key
has any value which satisfies the filter function when joined. If it doesn't,
we know we can join with null, since there was never (including this batch) a match
within the watermark period. If it does, there must have been a match at some point, so
we know we can't join with null.
```
But as explained the edge-case earlier, the assumption is not correct. As we don't have any good assumption to optimize which doesn't have edge-case, we have to track whether such row is matched with others before, and match with null row only when the row is not matched.
To track the matching of row, the patch adds a new state to streaming join state manager, and mark whether the row is matched to others or not. We leverage the information when dealing with eviction of rows which would be candidates to match with null rows.
This approach introduces new state format which is not compatible with old state format - queries with old state format will be still running but they will still have the issue and be required to discard checkpoint and rerun to take this patch in effect.
### Why are the changes needed?
This patch fixes a correctness issue.
### Does this PR introduce any user-facing change?
No for compatibility viewpoint, but we'll encourage end users to discard the old checkpoint and rerun the query if they run stream-stream outer join query with old checkpoint, which might be "yes" for the question.
### How was this patch tested?
Added UT which fails on current Spark and passes with this patch. Also passed existing streaming join UTs.

### What changes were proposed in this pull request?
With the latest string to literal optimization https://github.com/apache/spark/pull/26256, some interval strings can not be cast when there are some spaces between signs and unit values. After state `PARSE_SIGN`, it directly goes to `PARSE_UNIT_VALUE` when takes a space character as the end. So when there are some white spaces come before the real unit value, it fails to parse, we should add a new state like `TRIM_VALUE` to trim all these spaces.
How to re-produce, which aim the revisions since https://github.com/apache/spark/pull/26256 is merged

Hive support STORED AS new file format syntax:

CREATE TABLE tbl2 LIKE tbl STORED AS PARQUET;
```
We add a similar syntax for Spark. Here we separate to two features:
1. specify a different table provider in CREATE TABLE LIKE
2. Hive compatibility
In this PR, we address the first one:
- [ ] Using `USING provider` to specify a different table provider in CREATE TABLE LIKE.
- [ ] Using `STORED AS file_format` in CREATE TABLE LIKE to address Hive compatibility.
### Why are the changes needed?
Use CREATE TABLE tb1 LIKE tb2 command to create an empty table tb1 based on the definition of table tb2. The most user case is to create tb1 with the same schema of tb2. But an inconvenient case here is this command also copies the FileFormat from tb2, it cannot change the input/output format and serde. Add the ability of changing file format is useful for some scenarios like upgrading a table from a low performance file format to a high performance one (parquet, orc).

### What changes were proposed in this pull request?
In the PR, I propose new expression `MakeInterval` and register it as the function `make_interval`. The function accepts the following parameters:
- `years` - the number of years in the interval, positive or negative. The parameter is multiplied by 12, and added to interval's `months`.
- `months` - the number of months in the interval, positive or negative.
- `weeks` - the number of months in the interval, positive or negative. The parameter is multiplied by 7, and added to interval's `days`.
- `hours`, `mins` - the number of hours and minutes. The parameters can be negative or positive. They are converted to microseconds and added to interval's `microseconds`.
- `seconds` - the number of seconds with the fractional part in microseconds precision. It is converted to microseconds, and added to total interval's `microseconds` as `hours` and `minutes`.
For example:
```sql
spark-sql> select make_interval(2019, 11, 1, 1, 12, 30, 01.001001);
2019 years 11 months 8 days 12 hours 30 minutes 1.001001 seconds
```
### Why are the changes needed?
- To improve user experience with Spark SQL, and allow users making `INTERVAL` columns from other columns containing `years`, `months` ... `seconds`. Currently, users can make an `INTERVAL` column from other columns only by constructing a `STRING` column and cast it to `INTERVAL`. Have a look at the `IntervalBenchmark` as an example.
- To maintain feature parity with PostgreSQL which provides such function:
```sql
# SELECT make_interval(2019, 11);
make_interval
--------------------
2019 years 11 mons
```
### Does this PR introduce any user-facing change?
No
### How was this patch tested?

```sql
spark-sql> select -interval '-1 month 1 day -1 second';
1 months -1 days 1 seconds
spark-sql> select -interval -1 month 1 day -1 second;
1 months -1 days 1 seconds

### Why are the changes needed?
The proposed implementation is ~10 times faster. For example, parsing 9 interval units on JDK 8:
Before:
```
9 units w/ interval 14004 14125 116 0.1 14003.6 0.0X
9 units w/o interval 13785 14056 290 0.1 13784.9 0.0X
```
After:
```
9 units w/ interval 1343 1344 1 0.7 1343.0 0.3X
9 units w/o interval 1345 1349 8 0.7 1344.6 0.3X
```
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
- By new tests for `stringToInterval` in `IntervalUtilsSuite`
- By existing tests
Closes#26256 from MaxGekk/string-to-interval.

### What changes were proposed in this pull request?
Handle the inconsistence dividing zeros between literals and columns.
fix the null issue too.
### Why are the changes needed?
BUG FIX
### 1 Handle the inconsistence dividing zeros between literals and columns
```sql
-- !query 24
select
k,
v,
cast(k as interval) / v,
cast(k as interval) * v
from VALUES
('1 seconds', 1),
('2 seconds', 0),
('3 seconds', null),
(null, null),
(null, 0) t(k, v)
-- !query 24 schema
struct<k:string,v:int,divide_interval(CAST(k AS INTERVAL), CAST(v AS DOUBLE)):interval,multiply_interval(CAST(k AS INTERVAL), CAST(v AS DOUBLE)):interval>
-- !query 24 output
1 seconds 1 interval 1 seconds interval 1 seconds
2 seconds 0 interval 0 microseconds interval 0 microseconds
3 seconds NULL NULL NULL
NULL 0 NULL NULL
NULL NULL NULL NULL
```
```sql
-- !query 21
select interval '1 year 2 month' / 0
-- !query 21 schema
struct<divide_interval(interval 1 years 2 months, CAST(0 AS DOUBLE)):interval>
-- !query 21 output
NULL
```
in the first case, interval ’2 seconds ‘ / 0, it produces `interval 0 microseconds `
in the second case, it is `null`
### 2 null literal issues
```sql
-- !query 20
select interval '1 year 2 month' / null
-- !query 20 schema
struct<>
-- !query 20 output
org.apache.spark.sql.AnalysisException
cannot resolve '(interval 1 years 2 months / NULL)' due to data type mismatch: differing types in '(interval 1 years 2 months / NULL)' (interval and null).; line 1 pos 7
-- !query 22
select interval '4 months 2 weeks 6 days' * null
-- !query 22 schema
struct<>
-- !query 22 output
org.apache.spark.sql.AnalysisException
cannot resolve '(interval 4 months 20 days * NULL)' due to data type mismatch: differing types in '(interval 4 months 20 days * NULL)' (interval and null).; line 1 pos 7
-- !query 23
select null * interval '4 months 2 weeks 6 days'
-- !query 23 schema
struct<>
-- !query 23 output
org.apache.spark.sql.AnalysisException
cannot resolve '(NULL * interval 4 months 20 days)' due to data type mismatch: differing types in '(NULL * interval 4 months 20 days)' (null and interval).; line 1 pos 7
```
dividing or multiplying null literals, error occurs; where in column is fine as the first case

### What changes were proposed in this pull request?
Update `LocalShuffleReaderExec.outputPartitioning` to use attributes from `ReusedQueryStage`.
This also removes the override `doCanonicalize` in local/coalesced shuffle reader, as these 2 operators change the output partitioning. It's not safe to strip them in the canonicalized query plan.
### Why are the changes needed?
We will have an invalid output partitioning if we don fix it.
### Does this PR introduce any user-facing change?
no
