### What changes were proposed in this pull request?
Comparing to the long-running ThriftServer via start-script, we are more likely to hit the issue https://issues.apache.org/jira/browse/HIVE-10415 / https://issues.apache.org/jira/browse/SPARK-31626 in the developer API `startWithContext`
This PR apply SPARK-31626 to the developer API `startWithContext`
### Why are the changes needed?
Fix the issue described in SPARK-31626
### Does this PR introduce _any_ user-facing change?
Yes, the hive scratch dir will be deleted if cleanup is enabled for calling `startWithContext`
### How was this patch tested?

### What changes were proposed in this pull request?
This PR brings https://github.com/apache/spark/pull/28751 back
- It once reverted by 4a25200 because of inevitable maven test failure
- See related updates in this followup a0187cd6b5
- And reverted again because of the flakiness of the added unit tests
- In this PR, The flakiness reason found is caused by the hive metastore connection that the SparkSQLCLIService trying to create which turns out is unnecessary at all. This metastore client points to a dummy metastore server only.
- Also, add some cleanups for SharedThriftServer trait in before and after to prevent its configurations being polluted or polluting others
### Why are the changes needed?
fix flaky test
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
1. Add method `getTimeFormatters` to `HiveResult` which creates timestamp and date formatters.
2. Move creation of `dateFormatter` and `timestampFormatter` from the constructor of the `HiveResult` object to `HiveResult. hiveResultString()` via `getTimeFormatters`. This allows to resolve time zone ID from Spark's session time zone `spark.sql.session.timeZone` and create date/timestamp formatters only once before collecting `java.sql.Timestamp`/`java.sql.Date` values.
3. Create date/timestamp formatters once in SparkExecuteStatementOperation.
### Why are the changes needed?

### What changes were proposed in this pull request?
Set `spark.sql.datetime.java8API.enabled` to `true` in:
1. `SparkSQLEnv.init()` of Thrift server, and
2. `SparkSQLSessionManager.openSession()`
### Why are the changes needed?
1. Date and timestamp string literals are parsed by using Java 8 time API and Spark's session time zone. Before the changes, date/timestamp values were collected as legacy types `java.sql.Date`/`java.sql.Timestamp`, and the value of such types didn't respect the config `spark.sql.session.timeZone`. To have consistent view, users had to keep JVM time zone and Spark's session time zone in sync.
2. After the changes, formatting of date values doesn't depend on JVM time zone.
3. While returning dates/timestamps of Java 8 type, we can avoid dates/timestamps rebasing from Proleptic Gregorian calendar to the hybrid calendar (Julian + Gregorian), and the issues related to calendar switching.
4. Properly handle negative years (BCE).
5. Consistent conversion of date/timestamp strings to/from internal Catalyst types in both direction to and from Spark.
### Does this PR introduce any user-facing change?
Yes. Before:
```sql
spark-sql> select make_date(-44, 3, 15);

After:

```

### What changes were proposed in this pull request?
Timestamp literals in Spark are interpreted as timestamps in local timezone spark.sql.session.timeZone.
If JDBC client is e.g. in TimeZone UTC-7, and sets spark.sql.session.timeZone to PST, and sends a query "SELECT timestamp '2020-05-20 12:00:00'", and the JVM timezone of the Spark cluster is e.g. UTC+2, then what currently happens is:
* The timestamp literal in the query is interpreted as 12:00:00 UTC-7, i.e. 19:00:00 UTC.
* When it's returned from the query, it is collected as a java.sql.Timestamp object with Dataset.collect(), and put into a Thriftserver RowSet.
* Before sending it over the wire, the Timestamp is converted to String. This happens in explicitly in ColumnValue for RowBasedSet, and implicitly in ColumnBuffer for ColumnBasedSet (all non-primitive types are converted toString() there). The conversion toString uses JVM timezone, which results in a "21:00:00" (UTC+2) string representation.
* The client JDBC application parses gets a "21:00:00" Timestamp back (in it's JVM timezone; if the JDBC application cares about the correct UTC internal value, it should set spark.sql.session.timeZone to be consistent with its JVM timezone)
The problem is caused by the conversion happening in Thriftserver RowSet with the generic toString() function, instead of using HiveResults.toHiveString() that takes care of correct, timezone respecting conversions. This PR fixes it by converting the Timestamp values to String earlier, in SparkExecuteStatementOperation, using that function. This fixes SPARK-31861.
Thriftserver also did not work spark.sql.datetime.java8API.enabled, because the conversions in RowSet expected an Timestamp object instead of Instant object. Using HiveResults.toHiveString() also fixes that. For this reason, we also convert Date values in SparkExecuteStatementOperation as well - so that HiveResults.toHiveString() handles LocalDate as well. This fixes SPARK-31859.
Thriftserver also did not correctly set the active SparkSession. Because of that, configuration obtained using SQLConf.get was not the correct session configuration. This affected getting the correct spark.sql.session.timeZone. It is fixed by extending the use of SparkExecuteStatementOperation.withSchedulerPool to also set the correct active SparkSession. When the correct session is set, we also no longer need to maintain the pool mapping in a sessionToActivePool map. The scheduler pool can be just correctly retrieved from the session config. "withSchedulerPool" is renamed to "withLocalProperties" and moved into a mixin helper trait, because it should be applied with every operation. This fixes SPARK-31863.
I used the opportunity to move some repetitive code from the operations to the mixin helper trait.

### What changes were proposed in this pull request?
When I was developing some stuff based on the `DeveloperAPI ` `org.apache.spark.sql.hive.thriftserver.HiveThriftServer2#startWithContext`, I need to use thrift port randomly to avoid race on ports. But the `org.apache.hive.service.cli.thrift.ThriftCLIService#getPortNumber` do not respond to me with the actual bound port but always 0.
And the server log is not right too, after starting the server, it's hard to form to the right JDBC connection string.
```
INFO ThriftCLIService: Starting ThriftBinaryCLIService on port 0 with 5...500 worker threads
```
Indeed, the `53742` is the right port
```shell
lsof -nP -p `cat ./pid/spark-kentyao-org.apache.spark.sql.hive.thriftserver.HiveThriftServer2-1.pid` | grep LISTEN
java 18990 kentyao 288u IPv6 0x22858e3e60d6a0a7 0t0 TCP 10.242.189.214:53723 (LISTEN)

java 18990 kentyao 438u IPv6 0x22858e3e60d65d47 0t0 TCP *:53742 (LISTEN)
```
In the PR, when the port is configured 0, the `portNum` will be set to the real used port during the start process.
Also use 0 in thrift related tests to avoid potential flakiness.
### Why are the changes needed?
1 fix API bug
2 reduce test flakiness
### Does this PR introduce _any_ user-facing change?
yes, `org.apache.hive.service.cli.thrift.ThriftCLIService#getPortNumber` will always give you the actual port when it is configured 0.

### What changes were proposed in this pull request?
Currently while implementing pagination using the existing pagination framework, a lot of code is being copied as pointed out [here](https://github.com/apache/spark/pull/28485#pullrequestreview-408881656).
I introduced some changes in `PagedTable` which is the main trait for implementing the pagination.
* Added function for getting table parameters.
* Added a function for table header row. This will help in maintaining consistency across the tables. All the header rows across tables will be consistent now.
### Why are the changes needed?
* A lot of code is copied every time pagination is implemented for any table.
* Code readability is not great as lot of HTML is embedded.
* Paginating other tables will be a lot easier now.

### What changes were proposed in this pull request?
This is a recreation of #28155, which was reverted due to causing test failures.
The update methods in HiveThriftServer2Listener now check if the parameter operation/session ID actually exist in the `sessionList` and `executionList` respectively. This prevents NullPointerExceptions if the operation or session ID is unknown. Instead, a warning is written to the log.
To improve robustness, we also make the following changes in HiveSessionImpl.close():
- Catch any exception thrown by `operationManager.closeOperation`. If for any reason this throws an exception, other operations are not prevented from being closed.
- Handle not being able to access the scratch directory. When closing, all `.pipeout` files are removed from the scratch directory, which would have resulted in an NPE if the directory does not exist.
### Why are the changes needed?
The listener's update methods would throw an exception if the operation or session ID is unknown. In Spark 2, where the listener is called directly, this changes the caller's control flow. In Spark 3, the exception is caught by the ListenerBus but results in an uninformative NullPointerException.
In HiveSessionImpl.close(), if an exception is thrown when closing an operation, all following operations are not closed.

According to the error stack trace in the failed test, the test failed to instantiate a hive metastore client because of derby requirements.
```scala
Caused by: ERROR XBM0A:

However, it does not contain the expected 'service.properties' file.
Perhaps Derby was brought down in the middle of creating this database.
You may want to delete this directory and try creating the database again.
```
The derby requires the metastore dir does not exist, but it does exist probably due to the test case before it failed to clear the metastore dir

### What changes were proposed in this pull request?
This PR introduces a change to false for the insideComment flag on a newline. Fixing the issue introduced by SPARK-30049.
### Why are the changes needed?
Previously on SPARK-30049 a comment containing an unclosed quote produced the following issue:
```
spark-sql> SELECT 1 -- someone's comment here
> ;
Error in query:
extraneous input ';' expecting <EOF>(line 2, pos 0)
== SQL ==
SELECT 1 -- someone's comment here
;
^^^
```
This was caused because there was no flag for comment sections inside the splitSemiColon method to ignore quotes. SPARK-30049 added that flag and fixed the issue, but introduced the follwoing problem:
```
spark-sql> select
> 1,
> -- two
> 2;
Error in query:
mismatched input '<EOF>' expecting {'(', 'ADD', 'AFTER', 'ALL', 'ALTER', ...}(line 3, pos 2)
== SQL ==
select
1,
--^^^
```
This issue is generated by a missing turn-off for the insideComment flag with a newline.

No
### How was this patch tested?
- For previous tests using line-continuity(`\`) it was added a line-continuity rule in the SqlBase.g4 file to add the functionality to the SQL context.

### What changes were proposed in this pull request?
When I was finding the root cause for SPARK-31675, I noticed that it was very difficult for me to see what was actually going on, since it output nothing else but only
```sql
Error in query: java.lang.IllegalArgumentException: Wrong FS: blablah/.hive-staging_blahbla, expected: hdfs://cluster1
```
It is really hard for us to find causes through such a simple error message without a certain amount of experience.
In this PR, I propose to print all of the stack traces when AnalysisException occurs if there are underlying root causes, also we can escape this via `-S` option.
### Why are the changes needed?
In SPARK-11188,
>For analysis exceptions in the sql-shell, we should only print the error message to the screen. The stacktrace will never have useful information since this error is used to signify an error with the query.
But nowadays, some `AnalysisException`s do have useful information for us to debug, e.g. the `AnalysisException` below may contain exceptions from hive or Hadoop side.

### What changes were proposed in this pull request?
Run sql in spark thrift server, each session 's thrift server about method will be called in one thread, but when running query statement, we have two mode:
1. sync
2. async
5a482e7209/sql/hive-thriftserver/src/main/scala/org/apache/spark/sql/hive/thriftserver/SparkExecuteStatementOperation.scala (L205-L238)
In sync mode, we just submit query in current session's corresponding thread and wait Spark to running query and return result, and the query method will always wait for query return.
In async mode, in SparkExecuteStatementOperation, we will submit query in a backend thread pool, and update operation state, after submitted to backend thread poll, ExecuteStatement method will return a OperationHandle to client side, and client side will request operation status continuously. after backend thread running sql and return , it will update corresponding operation status, when client got operation status is final status, it will got error or start fetching result of this operation.
When we use pyhive connect to SparkThriftServer, it will run statement in sync mode.
When we query data of hive table , it will check serde class in HiveTableScanExec#addColumnMetadataToConf
5a482e7209/sql/hive/src/main/scala/org/apache/spark/sql/hive/execution/HiveTableScanExec.scala (L123)
```
public Class<? extends Deserializer> getDeserializerClass() {
try {
return Class.forName(this.getSerdeClassName(), true, Utilities.getSessionSpecifiedClassLoader());
} catch (ClassNotFoundException var2) {
throw new RuntimeException(var2);
}
}
public static ClassLoader getSessionSpecifiedClassLoader() {
SessionState state = SessionState.get();
if (state != null && state.getConf() != null) {
ClassLoader sessionCL = state.getConf().getClassLoader();
if (sessionCL != null) {
if (LOG.isTraceEnabled()) {
LOG.trace("Use session specified class loader");
}
return sessionCL;
} else {
if (LOG.isDebugEnabled()) {
LOG.debug("Session specified class loader not found, use thread based class loader");

}
} else {
if (LOG.isDebugEnabled()) {
LOG.debug("Hive Conf not found or Session not initiated, use thread based class loader instead");
}
return JavaUtils.getClassLoader();
}
}
```
Since we run statement in sync mode, it will use HiveSession's SessionState, and use it's conf's classLoader. then error happened.

`CliSuite.runCliWithin` was not matching for expected results correctly. It was matching for expected lines anywhere in stdout or stderr.
On the example of `Single command with --database` test:
In
```
runCliWithin(2.minute)(
"CREATE DATABASE hive_db_test;"
-> "",
"USE hive_test;"
-> "",
"CREATE TABLE hive_test(key INT, val STRING);"
-> "",
"SHOW TABLES;"
-> "hive_test"
)
```
It was looking for lines containing "", "", "" and then "hive_test".
However, the string "hive_test" was contained in "hive_test_db", and hence:
```

```
Because of that, it could kill the CLI process without really even creating the table. This was not expected. The test could be flaky depending on whether process.destroy() in the finally block managed to kill it before it actually creates the table.
I make the output checking more robust to not match on unexpected output, by making it check the echo of query output on the CLI. Also, wait for the CLI process to finish gracefully (triggered by closing its stdin), instead of killing it forcibly.
### Why are the changes needed?
org.apache.spark.sql.hive.thriftserver.CliSuite was flaky, and didn't test outputs as expected.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Existing tests in CLISuite. Tested several times with no flakiness. Was getting flaky results almost on every run before.

### What changes were proposed in this pull request?
In Spark CLI, we create a hive `CliSessionState` and it does not load the `hive-site.xml`. So the configurations in `hive-site.xml` will not take effects like other spark-hive integration apps.
Also, the warehouse directory is not correctly picked. If the `default` database does not exist, the `CliSessionState` will create one during the first time it talks to the metastore. The `Location` of the default DB will be neither the value of `spark.sql.warehousr.dir` nor the user-specified value of `hive.metastore.warehourse.dir`, but the default value of `hive.metastore.warehourse.dir `which will always be `/user/hive/warehouse`.
This PR fixes CLiSuite failure with the hive-1.2 profile in https://github.com/apache/spark/pull/27933.
In https://github.com/apache/spark/pull/27933, we fix the issue in JIRA by deciding the warehouse dir using all properties from spark conf and Hadoop conf, but properties from `--hiveconf` is not included, they will be applied to the `CliSessionState` instance after it initialized. When this command-line option key is `hive.metastore.warehouse.dir`, the actual warehouse dir is overridden. Because of the logic in Hive for creating the non-existing default database changed, that test passed with `Hive 2.3.6` but failed with `1.2`. So in this PR, Hadoop/Hive configurations are ordered by:
` spark.hive.xxx > spark.hadoop.xxx > --hiveconf xxx > hive-site.xml` througth `ShareState.loadHiveConfFile` before sessionState start
### Why are the changes needed?
Bugfix for Spark SQL CLI to pick right confs
### Does this PR introduce any user-facing change?
yes,
1. the non-exists default database will be created in the location specified by the users via `spark.sql.warehouse.dir` or `hive.metastore.warehouse.dir`, or the default value of `spark.sql.warehouse.dir` if none of them specified.
2. configurations from `hive-site.xml` will not override command-line options or the properties defined with `spark.hadoo(hive).` prefix in spark conf.

### What changes were proposed in this pull request?
Spark's Web UI is using an older version of Bootstrap (v. 2.3.2) for the portal pages. Bootstrap 2.x was moved to EOL in Aug 2013 and Bootstrap 3.x was moved to EOL in July 2019 (https://github.com/twbs/release). Older versions of Bootstrap are also getting flagged in security scans for various CVEs:
https://snyk.io/vuln/SNYK-JS-BOOTSTRAP-72889https://snyk.io/vuln/SNYK-JS-BOOTSTRAP-173700https://snyk.io/vuln/npm:bootstrap:20180529https://snyk.io/vuln/npm:bootstrap:20160627
I haven't validated each CVE, but it would be nice to resolve any potential issues and get on a supported release.
The bad news is that there have been quite a few changes between Bootstrap 2 and Bootstrap 4. I've tried updating the library, refactoring/tweaking the CSS and JS to maintain a similar appearance and functionality, and testing the UI for functionality and appearance. This is a fairly large change so I'm sure additional testing and fixes will be needed.
### How was this patch tested?
This has been manually tested, but there is a ton of functionality and there are many pages and detail pages so it is very possible bugs introduced from the upgrade were missed. Additional testing and feedback is welcomed. If it appears a whole page was missed let me know and I'll take a pass at addressing that page/section.

As a common usage and according to the spark doc, users may often just copy their `hive-site.xml` to Spark directly from hive projects. Sometimes, the config file is not that clean for spark and may cause some side effects.
for example, `hive.session.history.enabled` will create a log for the hive jobs but useless for spark and also it will not be deleted on JVM exit.
this pr
1) disable `hive.session.history.enabled` explicitly to disable creating `hive_job_log` file, e.g.
```
Hive history file=/var/folders/01/h81cs4sn3dq2dd_k4j6fhrmc0000gn/T//kentyao/hive_job_log_79c63b29-95a4-4935-a9eb-2d89844dfe4f_493861201.txt
```
2) set `hive.execution.engine` to `spark` explicitly in case the config is `tez` and casue uneccesary problem like this:
```
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/tez/dag/api/SessionNotRunning
at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:529)
```
### Why are the changes needed?
reduce overhead of internal complexity and users' hive cognitive load for running spark
### Does this PR introduce any user-facing change?
yes, `hive_job_log` file will not be created even enabled, and will not try to initialize tez kinds of stuff
### How was this patch tested?
add ut and verify manually

Based on the result and comment from https://github.com/apache/spark/pull/27552#discussion_r385531744
In the hive module, server-side provides datetime values simply use `value.toSting`, and the client-side regenerates the results back in `HiveBaseResultSet` with `java.sql.Date(Timestamp).valueOf`.
there will be inconsistency between client and server if we use java8 APIs

- Set `spark.sql.datetime.java8API.enabled` to `true` in `hiveResultString()`, and restore it back at the end of the call.
- Convert collected `java.time.Instant` & `java.time.LocalDate` to `java.sql.Timestamp` and `java.sql.Date` for correct formatting.
### Why are the changes needed?
Because of textual representation of timestamps/dates before 1582 year is incorrect:
```shell
$ export TZ="America/Los_Angeles"
$ ./bin/spark-sql -S
```
```sql

spark.sql.session.timeZone America/Los_Angeles
spark-sql> SELECT DATE_TRUNC('MILLENNIUM', DATE '1970-03-20');
1001-01-01 00:07:02
```
It must be 1001-01-01 00:**00:00**.
### Does this PR introduce any user-facing change?
Yes. After the changes:
```shell
$ export TZ="America/Los_Angeles"
$ ./bin/spark-sql -S
```
```sql
spark-sql> set spark.sql.session.timeZone=America/Los_Angeles;
spark.sql.session.timeZone America/Los_Angeles

### What changes were proposed in this pull request?
This PR scopes `SparkSession.active` to prevent problems with processing queries with possibly different spark sessions (and different configs). A new method, `withActive` is introduced on `SparkSession` that restores the previous spark session after the block of code is executed.
### Why are the changes needed?
`SparkSession.active` is a thread local variable that points to the current thread's spark session. It is important to note that the `SQLConf.get` method depends on `SparkSession.active`. In the current implementation it is possible that `SparkSession.active` points to a different session which causes various problems. Most of these problems arise because part of the query processing is done using the configurations of a different session. For example, when creating a data frame using a new session, i.e., `session.sql("...")`, part of the data frame is constructed using the currently active spark session, which can be a different session from the one used later for processing the query.
### Does this PR introduce any user-facing change?
The `withActive` method is introduced on `SparkSession`.
### How was this patch tested?
Unit tests (to be added)

### What changes were proposed in this pull request?
This PR propose to disallow negative `scale` of `Decimal` in Spark. And this PR brings two behavior changes:
1) for literals like `1.23E4BD` or `1.23E4`(with `spark.sql.legacy.exponentLiteralAsDecimal.enabled`=true, see [SPARK-29956](https://issues.apache.org/jira/browse/SPARK-29956)), we set its `(precision, scale)` to (5, 0) rather than (3, -2);
2) add negative `scale` check inside the decimal method if it exposes to set `scale` explicitly. If check fails, `AnalysisException` throws.
And user could still use `spark.sql.legacy.allowNegativeScaleOfDecimal.enabled` to restore the previous behavior.
### Why are the changes needed?
According to SQL standard,
> 4.4.2 Characteristics of numbers
An exact numeric type has a precision P and a scale S. P is a positive integer that determines the number of significant digits in a particular radix R, where R is either 2 or 10. S is a non-negative integer.
scale of Decimal should always be non-negative. And other mainstream databases, like Presto, PostgreSQL, also don't allow negative scale.
Presto:
```
presto:default> create table t (i decimal(2, -1));
Query 20191213_081238_00017_i448h failed: line 1:30: mismatched input '-'. Expecting: <integer>, <type>
create table t (i decimal(2, -1))
```
PostgrelSQL:
```
postgres=# create table t(i decimal(2, -1));
ERROR: NUMERIC scale -1 must be between 0 and precision 2
LINE 1: create table t(i decimal(2, -1));
^
```
And, actually, Spark itself already doesn't allow to create table with negative decimal types using SQL:
```
scala> spark.sql("create table t(i decimal(2, -1))");
org.apache.spark.sql.catalyst.parser.ParseException:
no viable alternative at input 'create table t(i decimal(2, -'(line 1, pos 28)
== SQL ==
create table t(i decimal(2, -1))

... 35 elided
```
However, it is still possible to create such table or `DatFrame` using Spark SQL programming API:
```
scala> val tb =
CatalogTable(
TableIdentifier("test", None),
CatalogTableType.MANAGED,
CatalogStorageFormat.empty,
StructType(StructField("i", DecimalType(2, -1) ) :: Nil))
```
```
scala> spark.sql("SELECT 1.23E4BD")
res2: org.apache.spark.sql.DataFrame = [1.23E+4: decimal(3,-2)]
```
while, these two different behavior could make user confused.
On the other side, even if user creates such table or `DataFrame` with negative scale decimal type, it can't write data out if using format, like `parquet` or `orc`. Because these formats have their own check for negative scale and fail on it.
```
scala> spark.sql("SELECT 1.23E4BD").write.saveAsTable("parquet")

```
So, I think it would be better to disallow negative scale totally and make behaviors above be consistent.
### Does this PR introduce any user-facing change?
Yes, if `spark.sql.legacy.allowNegativeScaleOfDecimal.enabled=false`, user couldn't create Decimal value with negative scale anymore.

```
(Here the error is logged as `WARN HiveConnection: Failed to connect to localhost:15441` - the actual stack trace can be seen on Jenkins test summary.)
The reason of test failure: Thrift(Binary|Http)CLIService prepare and launch the service asynchronously (in new thread), which suites are not waiting for completion and just start running tests, ends up with race condition.
That can be easily reproduced, via adding artificial sleep in `ThriftBinaryCLIService.run()` here:
ba3f6330dd/sql/hive-thriftserver/v2.3/src/main/java/org/apache/hive/service/cli/thrift/ThriftBinaryCLIService.java (L49)
(Note that `sleep` should be added before initializing server socket. E.g. Line 57)
This patch changes the test initialization logic to try executing simple query to wait until the service is available. The patch also refactors the code to apply the change both ThriftServerQueryTestSuite and ThriftServerWithSparkContextSuite easily.

### What changes were proposed in this pull request?
In this PR, we propose to use the value of `spark.sql.source.default` as the provider for `CREATE TABLE` syntax instead of `hive` in Spark 3.0.
And to help the migration, we introduce a legacy conf `spark.sql.legacy.respectHiveDefaultProvider.enabled` and set its default to `false`.
### Why are the changes needed?
1. Currently, `CREATE TABLE` syntax use hive provider to create table while `DataFrameWriter.saveAsTable` API using the value of `spark.sql.source.default` as a provider to create table. It would be better to make them consistent.
2. User may gets confused in some cases. For example:
```
CREATE TABLE t1 (c1 INT) USING PARQUET;
CREATE TABLE t2 (c1 INT);
```
In these two DDLs, use may think that `t2` should also use parquet as default provider since Spark always advertise parquet as the default format. However, it's hive in this case.
On the other hand, if we omit the USING clause in a CTAS statement, we do pick parquet by default if `spark.sql.hive.convertCATS=true`:
```
CREATE TABLE t3 USING PARQUET AS SELECT 1 AS VALUE;
CREATE TABLE t4 AS SELECT 1 AS VALUE;
```
And these two cases together can be really confusing.
3. Now, Spark SQL is very independent and popular. We do not need to be fully consistent with Hive's behavior.
### Does this PR introduce any user-facing change?
Yes, before this PR, using `CREATE TABLE` syntax will use hive provider. But now, it use the value of `spark.sql.source.default` as its provider.

[HIVE-12063](https://issues.apache.org/jira/browse/HIVE-12063) improved pad decimal numbers with trailing zeros to the scale of the column. The following description is copied from the description of HIVE-12063.
> HIVE-7373 was to address the problems of trimming tailing zeros by Hive, which caused many problems including treating 0.0, 0.00 and so on as 0, which has different precision/scale. Please refer to HIVE-7373 description. However, HIVE-7373 was reverted by HIVE-8745 while the underlying problems remained. HIVE-11835 was resolved recently to address one of the problems, where 0.0, 0.00, and so on cannot be read into decimal(1,1).
However, HIVE-11835 didn't address the problem of showing as 0 in query result for any decimal values such as 0.0, 0.00, etc. This causes confusion as 0 and 0.0 have different precision/scale than 0.
The proposal here is to pad zeros for query result to the type's scale. This not only removes the confusion described above, but also aligns with many other DBs. Internal decimal number representation doesn't change, however.

1. Refactor existing thrift server listener to support kvstore
2. Add history server plugin for thrift server listener and tab.
### Why are the changes needed?
Users can access Thriftserver tab from History server for both running and finished applications,
### Does this PR introduce any user-facing change?
Support for JDBC/ODBC tab for the WEBUI from History server
### How was this patch tested?
Add UT and Manual tests
1. Start Thriftserver and Historyserver
```
sbin/stop-thriftserver.sh
sbin/stop-historyserver.sh
sbin/start-thriftserver.sh

### What changes were proposed in this pull request?
allow the sql test files to specify different dimensions of config sets during testing. For example,
```
--CONFIG_DIM1 a=1
--CONFIG_DIM1 b=2,c=3
--CONFIG_DIM2 x=1
--CONFIG_DIM2 y=1,z=2
```
This example defines 2 config dimensions, and each dimension defines 2 config sets. We will run the queries 4 times:
1. a=1, x=1
2. a=1, y=1, z=2
3. b=2, c=3, x=1
4. b=2, c=3, y=1, z=2
### Why are the changes needed?
Currently `SQLQueryTestSuite` takes a long time. This is because we run each test at least 3 times, to check with different codegen modes. This is not necessary for most of the tests, e.g. DESC TABLE. We should only check these codegen modes for certain tests.
With the --CONFIG_DIM directive, we can do things like: test different join operator(broadcast or shuffle join) X different codegen modes.
After reducing testing time, we should be able to run thrifter server SQL tests with config settings.

### What changes were proposed in this pull request?
The local temporary view is session-scoped. Its lifetime is the lifetime of the session that created it. But now cache data is cross-session. Its lifetime is the lifetime of the Spark application. That's will cause the memory leak if cache a local temporary view in memory when the session closed.
In this PR, we uncache the cached data of local temporary view when session closed. This PR doesn't impact the cached data of global temp view and persisted view.
How to reproduce:
1. create a local temporary view v1
2. cache it in memory
3. close session without drop table v1.
The application will hold the memory forever. In a long running thrift server scenario. It's worse.

### 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.

### What changes were proposed in this pull request?
Currently, JDBC/ODBC tab in the WEBUI doesn't support hiding table. Other tabs in the web ui like, Jobs, stages, SQL etc supports hiding table (refer https://github.com/apache/spark/pull/22592).
In this PR, added the support for hide table in the jdbc/odbc tab also.
### Why are the changes needed?
Spark ui about the contents of the form need to have hidden and show features, when the table records very much. Because sometimes you do not care about the record of the table, you just want to see the contents of the next table, but you have to scroll the scroll bar for a long time to see the contents of the next table.

### What changes were proposed in this pull request?
To push the built jars to maven release repository, we need to remove the 'SNAPSHOT' tag from the version name.
Made the following changes in this PR:
* Update all the `3.0.0-SNAPSHOT` version name to `3.0.0-preview`
* Update the sparkR version number check logic to allow jvm version like `3.0.0-preview`
**Please note those changes were generated by the release script in the past, but this time since we manually add tags on master branch, we need to manually apply those changes too.**
We shall revert the changes after 3.0.0-preview release passed.
### Why are the changes needed?

### Does this PR introduce any user-facing change?
No
### How was this patch tested?
N/A
### What changes were proposed in this pull request?
This patch fixes the issue that external listeners are not initialized properly when `spark.sql.hive.metastore.jars` is set to either "maven" or custom list of jar.
("builtin" is not a case here - all jars in Spark classloader are also available in separate classloader)
The culprit is lazy initialization (lazy val or passing builder function) & thread context classloader. HiveClient leverages IsolatedClientLoader to properly load Hive and relevant libraries without issue - to not mess up with Spark classpath it uses separate classloader with leveraging thread context classloader.
But there's a messed-up case - SessionState is being initialized while HiveClient changed the thread context classloader from Spark classloader to Hive isolated one, and streaming query listeners are loaded from changed classloader while initializing SessionState.
This patch forces initializing SessionState in SparkSQLEnv to avoid such case.
### Why are the changes needed?
ClassNotFoundException could occur in spark-sql with specific configuration, as explained above.
### Does this PR introduce any user-facing change?
No, as I don't think end users assume the classloader of external listeners is only containing jars for Hive client.
### How was this patch tested?
New UT added which fails on master branch and passes with the patch.

### What changes were proposed in this pull request?
When adaptive execution is enabled, the Spark users who connected from JDBC always get adaptive execution error whatever the under root cause is. It's very confused. We have to check the driver log to find out why.
```shell
0: jdbc:hive2://localhost:10000> SELECT * FROM testData join testData2 ON key = v;
SELECT * FROM testData join testData2 ON key = v;
Error: Error running query: org.apache.spark.SparkException: Adaptive execution failed due to stage materialization failures. (state=,code=0)
0: jdbc:hive2://localhost:10000>
```
For example, a job queried from JDBC failed due to HDFS missing block. User still get the error message `Adaptive execution failed due to stage materialization failures`.
The easiest way to reproduce is changing the code of `AdaptiveSparkPlanExec`, to let it throws out an exception when it faces `StageSuccess`.
```scala
case class AdaptiveSparkPlanExec(
events.drainTo(rem)
(Seq(nextMsg) ++ rem.asScala).foreach {
case StageSuccess(stage, res) =>
// stage.resultOption = Some(res)
val ex = new SparkException("Wrapper Exception",
new IllegalArgumentException("Root cause is IllegalArgumentException for Test"))
errors.append(
new SparkException(s"Failed to materialize query stage: ${stage.treeString}", ex))
case StageFailure(stage, ex) =>
errors.append(
new SparkException(s"Failed to materialize query stage: ${stage.treeString}", ex))
```
### Why are the changes needed?
To make the error message more user-friend and more useful for query from JDBC.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
Manually test query:
```shell
0: jdbc:hive2://localhost:10000> CREATE TEMPORARY VIEW testData (key, value) AS SELECT explode(array(1, 2, 3, 4)), cast(substring(rand(), 3, 4) as string);

Support FETCH_PRIOR fetching in Thriftserver, and report correct fetch start offset it TFetchResultsResp.results.startRowOffset
The semantics of FETCH_PRIOR are as follow: Assuming the previous fetch returned a block of rows from offsets [10, 20)
* calling FETCH_PRIOR(maxRows=5) will scroll back and return rows [5, 10)
* calling FETCH_PRIOR(maxRows=10) again, will scroll back, but can't go earlier than 0. It will nevertheless return 10 rows, returning rows [0, 10) (overlapping with the previous fetch)
* calling FETCH_PRIOR(maxRows=4) again will again return rows starting from offset 0 - [0, 4)
* calling FETCH_NEXT(maxRows=6) after that will move the cursor forward and return rows [4, 10)
##### Client/server backwards/forwards compatibility:
Old driver with new server:
* Drivers that don't support FETCH_PRIOR will not attempt to use it
* Field TFetchResultsResp.results.startRowOffset was not set, old drivers don't depend on it.
New driver with old server
* Using an older thriftserver with FETCH_PRIOR will make the thriftserver return unsupported operation error. The driver can then recognize that it's an old server.
* Older thriftserver will return TFetchResultsResp.results.startRowOffset=0. If the client driver receives 0, it can know that it can not rely on it as correct offset. If the client driver intentionally wants to fetch from 0, it can use FETCH_FIRST.
### Why are the changes needed?
It's intended to be used to recover after connection errors. If a client lost connection during fetching (e.g. of rows [10, 20)), and wants to reconnect and continue, it could not know whether the request got lost before reaching the server, or on the response back. When it issued another FETCH_NEXT(10) request after reconnecting, because TFetchResultsResp.results.startRowOffset was not set, it could not know if the server will return rows [10,20) (because the previous request didn't reach it) or rows [20, 30) (because it returned data from the previous request but the connection got broken on the way back). Now, with TFetchResultsResp.results.startRowOffset the client can know after reconnecting which rows it is getting, and use FETCH_PRIOR to scroll back if a fetch block was lost in transmission.
Driver should always use FETCH_PRIOR after a broken connection.
* If the Thriftserver returns unsuported operation error, the driver knows that it's an old server that doesn't support it. The driver then must error the query, as it will also not support returning the correct startRowOffset, so the driver cannot reliably guarantee if it hadn't lost any rows on the fetch cursor.
* If the driver gets a response to FETCH_PRIOR, it should also have a correctly set startRowOffset, which the driver can use to position itself back where it left off before the connection broke.
* If FETCH_NEXT was used after a broken connection on the first fetch, and returned with an startRowOffset=0, then the client driver can't know if it's 0 because it's the older server version, or if it's genuinely 0. Better to call FETCH_PRIOR, as scrolling back may anyway be possibly required after a broken connection.
This way it is implemented in a backwards/forwards compatible way, and doesn't require bumping the protocol version. FETCH_ABSOLUTE might have been better, but that would require a bigger protocol change, as there is currently no field to specify the requested absolute offset.
### Does this PR introduce any user-facing change?
ODBC/JDBC drivers connecting to Thriftserver may now implement using the FETCH_PRIOR fetch order to scroll back in query results, and check TFetchResultsResp.results.startRowOffset if their cursor position is consistent after connection errors.

### What changes were proposed in this pull request?
When inserting a value into a column with the different data type, Spark performs type coercion. Currently, we support 3 policies for the store assignment rules: ANSI, legacy and strict, which can be set via the option "spark.sql.storeAssignmentPolicy":
1. ANSI: Spark performs the type coercion as per ANSI SQL. In practice, the behavior is mostly the same as PostgreSQL. It disallows certain unreasonable type conversions such as converting `string` to `int` and `double` to `boolean`. It will throw a runtime exception if the value is out-of-range(overflow).
2. Legacy: Spark allows the type coercion as long as it is a valid `Cast`, which is very loose. E.g., converting either `string` to `int` or `double` to `boolean` is allowed. It is the current behavior in Spark 2.x for compatibility with Hive. When inserting an out-of-range value to a integral field, the low-order bits of the value is inserted(the same as Java/Scala numeric type casting). For example, if 257 is inserted to a field of Byte type, the result is 1.
3. Strict: Spark doesn't allow any possible precision loss or data truncation in store assignment, e.g., converting either `double` to `int` or `decimal` to `double` is allowed. The rules are originally for Dataset encoder. As far as I know, no mainstream DBMS is using this policy by default.
Currently, the V1 data source uses "Legacy" policy by default, while V2 uses "Strict". This proposal is to use "ANSI" policy by default for both V1 and V2 in Spark 3.0.
### Why are the changes needed?
Following the ANSI SQL standard is most reasonable among the 3 policies.
### Does this PR introduce any user-facing change?
Yes.
The default store assignment policy is ANSI for both V1 and V2 data sources.
### How was this patch tested?

### What changes were proposed in this pull request?
This PR adds 2 changes regarding exception handling in `SQLQueryTestSuite` and `ThriftServerQueryTestSuite`
- fixes an expected output sorting issue in `ThriftServerQueryTestSuite` as if there is an exception then there is no need for sort
- introduces common exception handling in those 2 suites with a new `handleExceptions` method
### Why are the changes needed?
Currently `ThriftServerQueryTestSuite` passes on master, but it fails on one of my PRs (https://github.com/apache/spark/pull/23531) with this error (https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/111651/testReport/org.apache.spark.sql.hive.thriftserver/ThriftServerQueryTestSuite/sql_3/):
```
org.scalatest.exceptions.TestFailedException: Expected "

" Result did not match for query #4 WITH RECURSIVE r(level) AS ( VALUES (0) UNION ALL SELECT level + 1 FROM r ) SELECT * FROM r
```
The unexpected reversed order of expected output (error message comes first, then the exception class) is due to this line: https://github.com/apache/spark/pull/26028/files#diff-b3ea3021602a88056e52bf83d8782de8L146. It should not sort the expected output if there was an error during execution.

### What changes were proposed in this pull request?
For issue mentioned in [SPARK-29022](https://issues.apache.org/jira/browse/SPARK-29022)
Spark SQL CLI can't use class as serde class in jars add by SQL `ADD JAR`.
When we create table with `serde` class contains by jar added by SQL 'ADD JAR'.
We can create table with `serde` class construct success since we call `HiveClientImpl.createTable` under `withHiveState` method, it will add `clientLoader.classLoader` to `HiveClientImpl.state.getConf.classLoader`.
Jars added by SQL `ADD JAR` will be add to
1. `sparkSession.sharedState.jarClassLoader`.
2. 'HiveClientLoader.clientLoader.classLoader'
In Current spark-sql MODE, `HiveClientImpl.state` will use CliSessionState created when initialize
SparkSQLCliDriver, When we select data from table, it will check `serde` class, when call method `HiveTableScanExec#addColumnMetadataToConf()` to check for table desc serde class.
```
val deserializer = tableDesc.getDeserializerClass.getConstructor().newInstance()
deserializer.initialize(hiveConf, tableDesc.getProperties)
```
`getDeserializer` will use CliSessionState's hiveConf's classLoader in `Spark SQL CLI` mode.
But when we call `ADD JAR` in spark, the jar won't be added to `Classloader of CliSessionState' conf `, then `ClassNotFound` error happen.
So we reset `CliSessionState conf's classLoader ` to `sharedState.jarClassLoader` when `sharedState.jarClassLoader` has added jar passed by `HIVEAUXJARS`
Then when we use `ADD JAR ` to add jar, jar path will be added to CliSessionState's conf's ClassLoader

### What changes were proposed in this pull request?
Scala 2.13 emits a deprecation warning for procedure-like declarations:
```
def foo() {
...
```
This is equivalent to the following, so should be changed to avoid a warning:
```
def foo(): Unit = {
...
```
### Why are the changes needed?
It will avoid about a thousand compiler warnings when we start to support Scala 2.13. I wanted to make the change in 3.0 as there are less likely to be back-ports from 3.0 to 2.4 than 3.1 to 3.0, for example, minimizing that downside to touching so many files.
Unfortunately, that makes this quite a big change.

### What changes were proposed in this pull request?
After https://github.com/apache/spark/pull/25158 and https://github.com/apache/spark/pull/25458, SQL features of PostgreSQL are introduced into Spark. AFAIK, both features are implementation-defined behaviors, which are not specified in ANSI SQL.
In such a case, this proposal is to add a configuration `spark.sql.dialect` for choosing a database dialect.
After this PR, Spark supports two database dialects, `Spark` and `PostgreSQL`. With `PostgreSQL` dialect, Spark will:
1. perform integral division with the / operator if both sides are integral types;
2. accept "true", "yes", "1", "false", "no", "0", and unique prefixes as input and trim input for the boolean data type.
### Why are the changes needed?
Unify the external database dialect with one configuration, instead of small flags.
### Does this PR introduce any user-facing change?
A new configuration `spark.sql.dialect` for choosing a database dialect.
### How was this patch tested?

### What changes were proposed in this pull request?
Discuss in https://github.com/apache/spark/pull/25611
If cancel() and close() is called very quickly after the query is started, then they may both call cleanup() before Spark Jobs are started. Then sqlContext.sparkContext.cancelJobGroup(statementId) does nothing.
But then the execute thread can start the jobs, and only then get interrupted and exit through here. But then it will exit here, and no-one will cancel these jobs and they will keep running even though this execution has exited.
So when execute() was interrupted by `cancel()`, when get into catch block, we should call canJobGroup again to make sure the job was canceled.

### What changes were proposed in this pull request?
Currently, there are new configurations for compatibility with ANSI SQL:
* `spark.sql.parser.ansi.enabled`
* `spark.sql.decimalOperations.nullOnOverflow`
* `spark.sql.failOnIntegralTypeOverflow`
This PR is to add new configuration `spark.sql.ansi.enabled` and remove the 3 options above. When the configuration is true, Spark tries to conform to the ANSI SQL specification. It will be disabled by default.
### Why are the changes needed?
Make it simple and straightforward.

The new features for ANSI compatibility will be set via one configuration `spark.sql.ansi.enabled`.

### What changes were proposed in this pull request?
The intent to use the --hiveconf/--hivevar parameter is just an initialization value, so setting it once in ```SparkSQLSessionManager#openSession``` is sufficient, and each time the ```SparkExecuteStatementOperation``` setting causes the variable to not be modified.
### Why are the changes needed?
It is wrong to set the --hivevar/--hiveconf variable in every ```SparkExecuteStatementOperation```, which prevents variable updates.

While processing the Rowdata in the server side ColumnValue BigDecimal type value processed by server has to converted to the HiveDecmal data type for successful processing of query using Hive ODBC client.As per current logic corresponding to the Decimal column datatype, the Spark server uses BigDecimal, and the ODBC client uses HiveDecimal. If the data type does not match, the client fail to parse
Since this handing was missing the query executed in Hive ODBC client wont return or provides result to the user even though the decimal type column value data present.

This patch tries to keep consistency whenever UTF-8 charset is needed, as using `StandardCharsets.UTF_8` instead of using "UTF-8". If the String type is needed, `StandardCharsets.UTF_8.name()` is used.
This change also brings the benefit of getting rid of `UnsupportedEncodingException`, as we're providing `Charset` instead of `String` whenever possible.
This also changes some private Catalyst helper methods to operate on encodings as `Charset` objects rather than strings.

This PR implements Spark's own GetFunctionsOperation which mitigates the differences between Spark SQL and Hive UDFs. But our implementation is different from Hive's implementation:
- Our implementation always returns results. Hive only returns results when [(null == catalogName || "".equals(catalogName)) && (null == schemaName || "".equals(schemaName))](https://github.com/apache/hive/blob/rel/release-3.1.1/service/src/java/org/apache/hive/service/cli/operation/GetFunctionsOperation.java#L101-L119).
- Our implementation pads the `REMARKS` field with the function usage - Hive returns an empty string.
- Our implementation does not support `FUNCTION_TYPE`, but Hive does.

For Thrift server, It's downward compatible. Such as if a PROTOCOL_VERSION_V7 client connect to a PROTOCOL_VERSION_V8 server, when OpenSession, server will change his response's protocol version to min of (client and server).
`TProtocolVersion protocol = getMinVersion(CLIService.SERVER_VERSION,`
` req.getClient_protocol());`
then set it to OpenSession's response.
But if OpenSession failed , it won't execute behavior of reset response's protocol_version.
Then it will return server's origin protocol version.
Finally client will get en error as below:
Since we write a wrong database,, OpenSession failed, right protocol version haven't been rest.

The new Spark ThriftServer SparkGetTablesOperation implemented in https://github.com/apache/spark/pull/22794 does a catalog.getTableMetadata request for every table. This can get very slow for large schemas (~50ms per table with an external Hive metastore).
Hive ThriftServer GetTablesOperation uses HiveMetastoreClient.getTableObjectsByName to get table information in bulk, but we don't expose that through our APIs that go through Hive -> HiveClientImpl (HiveClient) -> HiveExternalCatalog (ExternalCatalog) -> SessionCatalog.
If we added and exposed getTableObjectsByName through our catalog APIs, we could resolve that performance problem in SparkGetTablesOperation.

## What changes were proposed in this pull request?
When we upgraded the built-in Hive to 2.3.4, the current `hive-thriftserver` module is not compatible, such as these Hive changes:
1. [HIVE-12442](https://issues.apache.org/jira/browse/HIVE-12442) HiveServer2: Refactor/repackage HiveServer2's Thrift code so that it can be used in the tasks
2. [HIVE-12237](https://issues.apache.org/jira/browse/HIVE-12237) Use slf4j as logging facade
3. [HIVE-13169](https://issues.apache.org/jira/browse/HIVE-13169) HiveServer2: Support delegation token based connection when using http transport
So this PR moves the incompatible code to `sql/hive-thriftserver/v1.2.1` and copies it to `sql/hive-thriftserver/v2.3.4` for the next code review.

## What changes were proposed in this pull request?
Fix build warnings -- see some details below.
But mostly, remove use of postfix syntax where it causes warnings without the `scala.language.postfixOps` import. This is mostly in expressions like "120000 milliseconds". Which, I'd like to simplify to things like "2.minutes" anyway.

## What changes were proposed in this pull request?
The user sets the value of spark.sql.thriftserver.scheduler.pool.
Spark thrift server saves this value in the LocalProperty of threadlocal type, but does not clean up after running, causing other sessions to run in the previously set pool name.

## What changes were proposed in this pull request?
When using fair scheduler mode for thrift server, we may have unpredictable result.
```
val pool = sessionToActivePool.get(parentSession.getSessionHandle)
if (pool != null) {
sqlContext.sparkContext.setLocalProperty(SparkContext.SPARK_SCHEDULER_POOL, pool)
}
```
The cause is we use thread pool to execute queries for thriftserver, and when we call setLocalProperty we may have unpredictab behavior.
```
/**
* Set a local property that affects jobs submitted from this thread, such as the Spark fair
* scheduler pool. User-defined properties may also be set here. These properties are propagated
* through to worker tasks and can be accessed there via
* [[org.apache.spark.TaskContext#getLocalProperty]].
*
* These properties are inherited by child threads spawned from this thread. This
* may have unexpected consequences when working with thread pools. The standard java
* implementation of thread pools have worker threads spawn other worker threads.
* As a result, local properties may propagate unpredictably.
*/
def setLocalProperty(key: String, value: String) {
if (value == null) {
localProperties.get.remove(key)
} else {
localProperties.get.setProperty(key, value)
}
}
```
