Wenchen Fan d04522187a [SPARK-28635][SQL] create CatalogManager to track registered v2 catalogs
## What changes were proposed in this pull request?

This is a pure refactor PR, which creates a new class `CatalogManager` to track the registered v2 catalogs, and provide the catalog up functionality.

`CatalogManager` also tracks the current catalog/namespace. We will implement corresponding commands in other PRs, like `USE CATALOG my_catalog`

## How was this patch tested?

existing tests

Closes #25368 from cloud-fan/refactor.

[SPARK-28650][SS][DOC] Correct explanation of guarantee for ForeachWriter
#  What changes were proposed in this pull request?

This patch modifies the explanation of guarantee for ForeachWriter as it doesn't guarantee same output for `(partitionId, epochId)`. Refer the description of [SPARK-28650](https://issues.apache.org/jira/browse/SPARK-28650) for more details.

Spark itself still guarantees same output for same epochId (batch) if the preconditions are met, 1) source is always providing the same input records for same offset request. 2) the query is idempotent in overall (indeterministic calculation like now(), random() can break this).

Assuming breaking preconditions as an exceptional case (the preconditions are implicitly required even before), we still can describe the guarantee with `epochId`, though it will be  harder to leverage the guarantee: 1) ForeachWriter should implement a feature to track whether all the partitions are written successfully for given `epochId` 2) There's pretty less chance to leverage the fact, as the chance for Spark to successfully write all partitions and fail to checkpoint the batch is small.

Credit to zsxwing on discovering the broken guarantee.

## How was this patch tested?

This is just a documentation change, both on javadoc and guide doc.

Closes #25407 from HeartSaVioR/SPARK-28650.

lihao 79464bed2f [SPARK-28662][SQL] Create Hive Partitioned Table DDL should fail when partition column type missed
## What changes were proposed in this pull request?
Create Hive Partitioned Table without specifying data type for partition column will success unexpectedly.
```HiveQL
// create a hive table partition by b, but the data type of b isn't specified.
CREATE TABLE tbl(a int) PARTITIONED BY (b) STORED AS parquet
```
In https://issues.apache.org/jira/browse/SPARK-26435 ,  PARTITIONED BY clause  are extended to support Hive CTAS as following:
```ANTLR
// Before
(PARTITIONED BY '(' partitionColumns=colTypeList ')'

 // After
(PARTITIONED BY '(' partitionColumns=colTypeList ')'|
PARTITIONED BY partitionColumnNames=identifierList) |
```

Create Table Statement like above case will pass the syntax check,  and recognized as (PARTITIONED BY partitionColumnNames=identifierList) 。

This PR  will check this case in visitCreateHiveTable and throw a exception which contains  explicit error message to user.

## How was this patch tested?

Added tests.

Closes #25390 from lidinghao/hive-ddl-fix.

Mick Jermsurawong b79cf0d143 [SPARK-28224][SQL] Check overflow in decimal Sum aggregate
## What changes were proposed in this pull request?
- Currently `sum` in aggregates for decimal type can overflow and return null.
  - `Sum` expression codegens arithmetic on `sql.Decimal` and the output which preserves scale and precision goes into `UnsafeRowWriter`. Here overflowing will be converted to null when writing out.
  - It also does not go through this branch in `DecimalAggregates` because it's expecting precision of the sum (not the elements to be summed) to be less than 5.
4ebff5b6d6/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/Optimizer.scala (L1400-L1403)

- This PR adds the check at the final result of the sum operator itself.

## How was this patch tested?

- Added an integration test on dataframe suite

Wenchen Fan 97dc4c0bfc [SPARK-28744][SQL][TEST] rename SharedSQLContext to SharedSparkSession
## What changes were proposed in this pull request?

The Spark SQL test framework needs to support 2 kinds of tests:
1. tests inside Spark to test Spark itself (extends `SparkFunSuite`)
2. test outside of Spark to test Spark applications (introduced at b57ed2245c)

The class hierarchy of the major testing traits:
![image](https://user-images.githubusercontent.com/3182036/63088526-c0f0af80-bf87-11e9-9bed-c144c2486da9.png)

`PlanTestBase`, `SQLTestUtilsBase` and `SharedSparkSession` intentionally don't extend `SparkFunSuite`, so that they can be used for tests outside of Spark. Tests in Spark should extends `QueryTest` and/or `SharedSQLContext` in most cases.

However, the name is a little confusing. As a result, some test suites extend `SharedSparkSession` instead of `SharedSQLContext`. `SharedSparkSession` doesn't work well with `SparkFunSuite` as it doesn't have the special handling of thread auditing in `SharedSQLContext`. For example, you will see a warning starting with `===== POSSIBLE THREAD LEAK IN SUITE` when you run `DataFrameSelfJoinSuite`.

This PR proposes to rename `SharedSparkSession` to `SharedSparkSessionBase`, and rename `SharedSQLContext` to `SharedSparkSession`.

Yuming Wang efbb035902 [SPARK-28527][SQL][TEST] Re-run all the tests in SQLQueryTestSuite via Thrift Server
## What changes were proposed in this pull request?

This PR build a test framework that directly re-run all the tests in `SQLQueryTestSuite` via Thrift Server. But it's a little different from `SQLQueryTestSuite`:
1. Can not support [UDF testing](44e607e921/sql/core/src/test/scala/org/apache/spark/sql/SQLQueryTestSuite.scala (L293-L297)).
2. Can not support `DESC` command and `SHOW` command because `SQLQueryTestSuite` [formatted the output](1882912cca/sql/core/src/main/scala/org/apache/spark/sql/execution/HiveResult.scala (L38-L50).).

When building this framework, found two bug:
[SPARK-28624](https://issues.apache.org/jira/browse/SPARK-28624): `make_date` is inconsistent when reading from table
[SPARK-28611](https://issues.apache.org/jira/browse/SPARK-28611): Histogram's height is different

found two features that ThriftServer can not support:
[SPARK-28636](https://issues.apache.org/jira/browse/SPARK-28636): ThriftServer can not support decimal type with negative scale
[SPARK-28637](https://issues.apache.org/jira/browse/SPARK-28637): ThriftServer can not support interval type

Also, found two inconsistent behavior:
[SPARK-28620](https://issues.apache.org/jira/browse/SPARK-28620): Double type returned for float type in Beeline/JDBC
[SPARK-28619](https://issues.apache.org/jira/browse/SPARK-28619):  The golden result file is different when tested by `bin/spark-sql`

Gengliang Wang 92bfd9a317 [SPARK-28757][SQL] File table location should include both values of option path and paths
### What changes were proposed in this pull request?
If both options `path` and `paths` are passed to file data source v2, both values of the options should be included as the target paths.

### Why are the changes needed?
In V1 implementation, file table location includes both values of option `path` and `paths`.
In the refactoring of https://github.com/apache/spark/pull/24025, the value of option `path` is ignored if "paths" are specified. We should make it consistent with V1.

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

### How was this patch tested?

Maxim Gekk 96ca734fb7 [SPARK-28745][SQL][TEST] Add benchmarks for extract()
## What changes were proposed in this pull request?

Added new benchmark `ExtractBenchmark` for the `EXTRACT(field FROM source)` function. It was executed on all currently supported values of the `field` argument:  `MILLENNIUM`, `CENTURY`, `DECADE`, `YEAR`, `ISOYEAR`, `QUARTER`, `MONTH`, `WEEK`, `DAY`, `DAYOFWEEK`, `HOUR`, `MINUTE`, `SECOND`, `MILLISECONDS`, `MICROSECONDS`, `EPOCH`. The `cast(id as timestamp)` was taken as the `source` argument.

## How was this patch tested?

By running the benchmark via:
```
$ SPARK_GENERATE_BENCHMARK_FILES=1 build/sbt "sql/test:runMain org.apache.spark.sql.execution.benchmark.ExtractBenchmark"
```

Burak Yavuz 0526529b31 [SPARK-28666] Support saveAsTable for V2 tables through Session Catalog
## What changes were proposed in this pull request?

We add support for the V2SessionCatalog for saveAsTable, such that V2 tables can plug in and leverage existing DataFrameWriter.saveAsTable APIs to write and create tables through the session catalog.

## How was this patch tested?

Unit tests. A lot of tests broke under hive when things were not working properly under `ResolveTables`, therefore I believe the current set of tests should be sufficient in testing the table resolution and read code paths.

Closes #25402 from brkyvz/saveAsV2.

Maxim Gekk 3a4afce96c [SPARK-28687][SQL] Support epoch, isoyear, milliseconds and microseconds at extract()
## What changes were proposed in this pull request?

In the PR, I propose new expressions `Epoch`, `IsoYear`, `Milliseconds` and `Microseconds`, and support additional parameters of `extract()` for feature parity with PostgreSQL (https://www.postgresql.org/docs/11/functions-datetime.html#FUNCTIONS-DATETIME-EXTRACT):

1. `epoch` - the number of seconds since 1970-01-01 00:00:00 local time in microsecond precision.
2. `isoyear` - the ISO 8601 week-numbering year that the date falls in. Each ISO 8601 week-numbering year begins with the Monday of the week containing the 4th of January.
3. `milliseconds` - the seconds field including fractional parts multiplied by 1,000.
4. `microseconds` - the seconds field including fractional parts multiplied by 1,000,000.

Here are examples:
```sql
spark-sql> SELECT EXTRACT(EPOCH FROM TIMESTAMP '2019-08-11 19:07:30.123456');
1565550450.123456
spark-sql> SELECT EXTRACT(ISOYEAR FROM DATE '2006-01-01');
2005
spark-sql> SELECT EXTRACT(MILLISECONDS FROM TIMESTAMP '2019-08-11 19:07:30.123456');
30123.456
spark-sql> SELECT EXTRACT(MICROSECONDS FROM TIMESTAMP '2019-08-11 19:07:30.123456');
30123456
```

## How was this patch tested?

Added new tests to `DateExpressionsSuite`, and uncommented existing tests in `extract.sql` and `pgSQL/date.sql`.

xy_xin 2eeb25e52d [SPARK-28351][SQL] Support DELETE in DataSource V2
## What changes were proposed in this pull request?

This pr adds DELETE support for V2 datasources. As a first step, this pr only support delete by source filters:
```scala
void delete(Filter[] filters);
```
which could not deal with complicated cases like subqueries.

Since it's uncomfortable to embed the implementation of DELETE in the current V2 APIs, a new mix-in of datasource is added, which is called `SupportsMaintenance`, similar to `SupportsRead` and `SupportsWrite`.  A datasource which can be maintained means we can perform DELETE/UPDATE/MERGE/OPTIMIZE on the datasource, as long as the datasource implements the necessary mix-ins.

## How was this patch tested?

Dilip Biswal 331f2657d9 [SPARK-27768][SQL] Support Infinity/NaN-related float/double literals case-insensitively
## What changes were proposed in this pull request?
Here is the problem description from the JIRA.
```
When the inputs contain the constant 'infinity', Spark SQL does not generate the expected results.

SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('1'), (CAST('infinity' AS DOUBLE))) v(x);
SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('infinity'), ('1')) v(x);
SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('infinity'), ('infinity')) v(x);
SELECT avg(CAST(x AS DOUBLE)), var_pop(CAST(x AS DOUBLE))
FROM (VALUES ('-infinity'), ('infinity')) v(x);
 The root cause: Spark SQL does not recognize the special constants in a case insensitive way. In PostgreSQL, they are recognized in a case insensitive way.

Link: https://www.postgresql.org/docs/9.3/datatype-numeric.html
```

In this PR, the casting code is enhanced to handle these `special` string literals in case insensitive manner.

## How was this patch tested?
Added tests in CastSuite and modified existing test suites.

Maxim Gekk 3d85c54895 [SPARK-28700][SQL] Use DECIMAL type for sec in make_timestamp()
## What changes were proposed in this pull request?

Changed type of `sec` argument in the `make_timestamp()` function from `DOUBLE` to `DECIMAL(8, 6)`. The scale is set to 6 to cover microsecond fractions, and the precision is 2 digits for seconds + 6 digits for microsecond fraction. New type prevents losing precision in some cases, for example:

Before:
```sql
spark-sql> select make_timestamp(2019, 8, 12, 0, 0, 58.000001);
2019-08-12 00:00:58
```

After:
```sql
spark-sql> select make_timestamp(2019, 8, 12, 0, 0, 58.000001);
2019-08-12 00:00:58.000001
```

Also switching to `DECIMAL` fixes rounding `sec` towards "nearest neighbor" unless both neighbors are equidistant, in which case round up. For example:

Before:
```sql
spark-sql> select make_timestamp(2019, 8, 12, 0, 0, 0.1234567);
2019-08-12 00:00:00.123456
```

After:
```sql
spark-sql> select make_timestamp(2019, 8, 12, 0, 0, 0.1234567);
2019-08-12 00:00:00.123457
```

## How was this patch tested?

This was tested by `DateExpressionsSuite` and `pgSQL/timestamp.sql`.

Liang-Chi Hsieh e6a0385289 [SPARK-28422][SQL][PYTHON] GROUPED_AGG pandas_udf should work without group by clause
## What changes were proposed in this pull request?

A GROUPED_AGG pandas python udf can't work, if without group by clause, like `select udf(id) from table`.

This doesn't match with aggregate function like sum, count..., and also dataset API like `df.agg(udf(df['id']))`.

When we parse a udf (or an aggregate function) like that from SQL syntax, it is known as a function in a project. `GlobalAggregates` rule in analysis makes such project as aggregate, by looking for aggregate expressions. At the moment, we should also look for GROUPED_AGG pandas python udf.

## How was this patch tested?

Added tests.

Maxim Gekk 924d794a6f [SPARK-28656][SQL] Support millennium, century and decade at extract()
## What changes were proposed in this pull request?

In the PR, I propose new expressions `Millennium`, `Century` and `Decade`, and support additional parameters of `extract()` for feature parity with PostgreSQL (https://www.postgresql.org/docs/11/functions-datetime.html#FUNCTIONS-DATETIME-EXTRACT):

1. `millennium` - the current millennium for given date (or a timestamp implicitly casted to a date). For example, years in the 1900s are in the second millennium. The third millennium started _January 1, 2001_.
2. `century` - the current millennium for given date (or timestamp). The first century starts at 0001-01-01 AD.
3. `decade` - the current decade for given date (or timestamp). Actually, this is the year field divided by 10.

Here are examples:
```sql
spark-sql> SELECT EXTRACT(MILLENNIUM FROM DATE '1981-01-19');
2
spark-sql> SELECT EXTRACT(CENTURY FROM DATE '1981-01-19');
20
spark-sql> SELECT EXTRACT(DECADE FROM DATE '1981-01-19');
198
```

## How was this patch tested?

Added new tests to `DateExpressionsSuite` and uncommented existing tests in `pgSQL/date.sql`.

Shixiong Zhu 5bb69945e4 [SPARK-28651][SS] Force the schema of Streaming file source to be nullable
## What changes were proposed in this pull request?

Right now, batch DataFrame always changes the schema to nullable automatically (See this line: 325bc8e9c6/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/DataSource.scala (L399)). But streaming file source is missing this.

This PR updates the streaming file source schema to force it be nullable. I also added a flag `spark.sql.streaming.fileSource.schema.forceNullable` to disable this change since some users may rely on the old behavior.

## How was this patch tested?

Burak Yavuz 5368eaa2fc [SPARK-28565][SQL] DataFrameWriter saveAsTable support for V2 catalogs
## What changes were proposed in this pull request?

Adds support for V2 catalogs and the V2SessionCatalog for V2 tables for saveAsTable.
If the table can resolve through the V2SessionCatalog, we use SaveMode for datasource v1 for backwards compatibility to select the code path we're going to hit.

Depending on the SaveMode:
 - SaveMode.Append:
     a) If table exists: Use AppendData.byName
     b) If table doesn't exist, use CTAS (ignoreIfExists = false)
 - SaveMode.Overwrite: Use RTAS (orCreate = true)
 - SaveMode.Ignore: Use CTAS (ignoreIfExists = true)
 - SaveMode.ErrorIfExists: Use CTAS (ignoreIfExists = false)

## How was this patch tested?

Unit tests in DataSourceV2DataFrameSuite

Maxim Gekk 997d153e54 [SPARK-28017][SQL] Support additional levels of truncations by DATE_TRUNC/TRUNC
## What changes were proposed in this pull request?

I propose new levels of truncations for the `date_trunc()` and `trunc()` functions:
1. `MICROSECOND` and `MILLISECOND` truncate values of the `TIMESTAMP` type to microsecond and millisecond precision.
2. `DECADE`, `CENTURY` and `MILLENNIUM` truncate dates/timestamps to lowest date of current decade/century/millennium.

Also the `WEEK` and `QUARTER` levels have been supported by the `trunc()` function.

The function is implemented similarly to `date_trunc` in PostgreSQL: https://www.postgresql.org/docs/11/functions-datetime.html#FUNCTIONS-DATETIME-TRUNC to maintain feature parity with it.

Here are examples of `TRUNC`:
```sql
spark-sql> SELECT TRUNC('2015-10-27', 'DECADE');
2010-01-01
spark-sql> set spark.sql.datetime.java8API.enabled=true;
spark.sql.datetime.java8API.enabled	true
spark-sql> SELECT TRUNC('1999-10-27', 'millennium');
1001-01-01
```
Examples of `DATE_TRUNC`:
```sql
spark-sql> SELECT DATE_TRUNC('CENTURY', '2015-03-05T09:32:05.123456');
2001-01-01T00:00:00Z
```

## What changes were proposed in this pull request?

Plans after "Extract Python UDFs" are very flaky and error-prone to other rules.

For instance, if we add some rules, for instance, `PushDownPredicates` in `postHocOptimizationBatches`, the test in `BatchEvalPythonExecSuite` fails:

```scala
test("Python UDF refers to the attributes from more than one child") {
  val df = Seq(("Hello", 4)).toDF("a", "b")

```

```
Invalid PythonUDF dummyUDF(a#63, c#74), requires attributes from more than one child.
```

This is because Python UDF extraction optimization is rolled back as below:

```
=== Applying Rule org.apache.spark.sql.catalyst.optimizer.PushDownPredicates ===
!Filter (dummyUDF(a#7, c#18) = dummyUDF(d#19, c#18))   Join Cross, (dummyUDF(a#7, c#18) = dummyUDF(d#19, c#18))
!+- Join Cross                                         :- Project [_1#2 AS a#7, _2#3 AS b#8]
!   :- Project [_1#2 AS a#7, _2#3 AS b#8]              :  +- LocalRelation [_1#2, _2#3]
!   :  +- LocalRelation [_1#2, _2#3]                   +- Project [_1#13 AS c#18, _2#14 AS d#19]
!   +- Project [_1#13 AS c#18, _2#14 AS d#19]             +- LocalRelation [_1#13, _2#14]
!      +- LocalRelation [_1#13, _2#14]
```

Seems we should do Python UDFs cases at the last even after post hoc rules.

Note that this actually rather follows the way in previous versions when those were in physical plans (see SPARK-24721 and SPARK-12981). Those optimization rules were supposed to be placed at the end.

Note that I intentionally didn't move `ExperimentalMethods` (`spark.experimental.extraStrategies`). This is an explicit experimental API and I wanted to just-in-case workaround after this change for now.

maryannxue 325bc8e9c6 [SPARK-28583][SQL] Subqueries should not call onUpdatePlan in Adaptive Query Execution
## What changes were proposed in this pull request?

Subqueries do not have their own execution id, thus when calling `AdaptiveSparkPlanExec.onUpdatePlan`, it will actually get the `QueryExecution` instance of the main query, which is wasteful and problematic. It could cause issues like stack overflow or dead locks in some circumstances.

This PR fixes this issue by making `AdaptiveSparkPlanExec` compare the `QueryExecution` object retrieved by current execution ID against the `QueryExecution` object from which this plan is created, and only update the UI when the two instances are the same.

## How was this patch tested?

Wenchen Fan 469423f338 [SPARK-28595][SQL] explain should not trigger partition listing
## What changes were proposed in this pull request?

Sometimes when you explain a query, you will get stuck for a while. What's worse, you will get stuck again if you explain again.

This is caused by `FileSourceScanExec`:
1. In its `toString`, it needs to report the number of partitions it reads. This needs to query the hive metastore.
2. In its `outputOrdering`, it needs to get all the files. This needs to query the hive metastore.

This PR fixes by:
1. `toString` do not need to report the number of partitions it reads. We should report it via SQL metrics.
2. The `outputOrdering` is not very useful. We can only apply it if a) all the bucket columns are read. b) there is only one file in each bucket. This condition is really hard to meet, and even if we meet, sorting an already sorted file is pretty fast and avoiding the sort is not that useful. I think it's worth to give up this optimization so that explain don't need to get stuck.

Nik Vanderhoof 9e931e787d [SPARK-27905][SQL] Add higher order function 'forall'
## What changes were proposed in this pull request?

Add's the higher order function `forall`, which tests an array to see if a predicate holds for every element.
The function is implemented in `org.apache.spark.sql.catalyst.expressions.ArrayForAll`.
The function is added to the function registry under the pretty name `forall`.

## How was this patch tested?

I've added appropriate unit tests for the new ArrayForAll expression in
`sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/HigherOrderFunctionsSuite.scala`.

Also added tests for the function in `sql/core/src/test/scala/org/apache/spark/sql/DataFrameFunctionsSuite.scala`.

Maxim Gekk 9e3aab8b95 [SPARK-28623][SQL] Support dow, isodow and doy by extract()
## What changes were proposed in this pull request?

In the PR, I propose to use existing expressions `DayOfYear`, `WeekDay` and `DayOfWeek`, and support additional parameters of `extract()` for feature parity with PostgreSQL (https://www.postgresql.org/docs/11/functions-datetime.html#FUNCTIONS-DATETIME-EXTRACT):

1. `dow` - the day of the week as Sunday (0) to Saturday (6)
2. `isodow` - the day of the week as Monday (1) to Sunday (7)
3. `doy` - the day of the year (1 - 365/366)

Here are examples:
```sql
spark-sql> SELECT EXTRACT(DOW FROM TIMESTAMP '2001-02-16 20:38:40');
5
spark-sql> SELECT EXTRACT(ISODOW FROM TIMESTAMP '2001-02-18 20:38:40');

Jungtaek Lim (HeartSaVioR) 128ea37bda [SPARK-28601][CORE][SQL] Use StandardCharsets.UTF_8 instead of "UTF-8" string representation, and get rid of UnsupportedEncodingException
## What changes were proposed in this pull request?

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.

## How was this patch tested?

Existing unit tests.

Wenchen Fan 03e3006312 [SPARK-28213][SQL][FOLLOWUP] code cleanup and bug fix for columnar execution framework
## What changes were proposed in this pull request?

I did a post-hoc review of https://github.com/apache/spark/pull/25008 , and would like to propose some cleanups/fixes/improvements:

1. Do not track the scanTime metrics in `ColumnarToRowExec`. This metrics is specific to file scan, and doesn't make sense for a general batch-to-row operator.
2. Because of 2, we need to track scanTime when building RDDs in the file scan node.
3. use `RDD#mapPartitionsInternal` instead of `flatMap` in several places, as `mapPartitionsInternal` is created for Spark SQL and we use it in almost all the SQL operators.
4. Add `limitNotReachedCond` in `ColumnarToRowExec`. This was in the `ColumnarBatchScan` before and is critical for performance.
5. Clear the relationship between codegen stage and columnar stage. The whole-stage-codegen framework is completely row-based, so these 2 kinds of stages can NEVER overlap. When they are adjacent, it's either a `RowToColumnarExec` above `WholeStageExec`, or a `ColumnarToRowExec` above the `InputAdapter`.
6. Reuse the `ColumnarBatch` in `RowToColumnarExec`. We don't need to create a new one every time, just need to reset it.
7. Do not skip testing full scan node in `LogicalPlanTagInSparkPlanSuite`
8. Add back the removed tests in `WholeStageCodegenSuite`.

Wenchen Fan 6fb79af48c [SPARK-28344][SQL] detect ambiguous self-join and fail the query
## What changes were proposed in this pull request?

This is an alternative solution of https://github.com/apache/spark/pull/24442 . It fails the query if ambiguous self join is detected, instead of trying to disambiguate it. The problem is that, it's hard to come up with a reasonable rule to disambiguate, the rule proposed by #24442 is mostly a heuristic.

### background of the self-join problem:
This is a long-standing bug and I've seen many people complaining about it in JIRA/dev list.

A typical example:
```
val df1 = …
val df2 = df1.filter(...)
df1.join(df2, df1("a") > df2("a")) // returns empty result
```
The root cause is, `Dataset.apply` is so powerful that users think it returns a column reference which can point to the column of the Dataset at anywhere. This is not true in many cases. `Dataset.apply` returns an `AttributeReference` . Different Datasets may share the same `AttributeReference`. In the example above, `df2` adds a Filter operator above the logical plan of `df1`, and the Filter operator reserves the output `AttributeReference` of its child. This means, `df1("a")` is exactly the same as `df2("a")`, and `df1("a") > df2("a")` always evaluates to false.

### The rule to detect ambiguous column reference caused by self join:
We can reuse the infra in #24442 :
1. each Dataset has a globally unique id.
2. the `AttributeReference` returned by `Dataset.apply` carries the ID and column position(e.g. 3rd column of the Dataset) via metadata.
3. the logical plan of a `Dataset` carries the ID via `TreeNodeTag`

When self-join happens, the analyzer asks the right side plan of join to re-generate output attributes with new exprIds. Based on it, a simple rule to detect ambiguous self join is:
1. find all column references (i.e. `AttributeReference`s with Dataset ID and col position) in the root node of a query plan.
2. for each column reference, traverse the query plan tree, find a sub-plan that carries Dataset ID and the ID is the same as the one in the column reference.
3. get the corresponding output attribute of the sub-plan by the col position in the column reference.
4. if the corresponding output attribute has a different exprID than the column reference, then it means this sub-plan is on the right side of a self-join and has regenerated its output attributes. This is an ambiguous self join because the column reference points to a table being self-joined.

Yuming Wang 21a18c6490 [SPARK-28614][SQL][TEST] Do not remove leading write space in the golden result file
## What changes were proposed in this pull request?

It's hard to know if the query needs to be sorted like [`SQLQueryTestSuite.isSorted`](2ecc39c8d3/sql/core/src/test/scala/org/apache/spark/sql/SQLQueryTestSuite.scala (L375-L380)) when building a test framework for Thriftserver. So we  can sort both  the `outputs` and  the `expectedOutputs. However, we removed leading write space in the golden result file. This can lead to inconsistent results.
This PR makes it does not remove leading write space in the golden result file. Trailing write space still needs to be removed.

Sean Owen b148bd5ccb [SPARK-28519][SQL] Use StrictMath log, pow functions for platform independence
## What changes were proposed in this pull request?

See discussion on the JIRA (and dev). At heart, we find that math.log and math.pow can actually return slightly different results across platforms because of hardware optimizations. For the actual SQL log and pow functions, I propose that we should use StrictMath instead to ensure the answers are already the same. (This should have the benefit of helping tests pass on aarch64.)

Further, the atanh function (which is not part of java.lang.Math) can be implemented in a slightly different and more accurate way.

## How was this patch tested?

Existing tests (which will need to be changed).
Some manual testing locally to understand the numeric issues.

Liang-Chi Hsieh 77c7e91e02 [SPARK-28445][SQL][PYTHON] Fix error when PythonUDF is used in both group by and aggregate expression
## What changes were proposed in this pull request?

When PythonUDF is used in group by, and it is also in aggregate expression, like

```
SELECT pyUDF(a + 1), COUNT(b) FROM testData GROUP BY pyUDF(a + 1)
```

It causes analysis exception in `CheckAnalysis`, like
```
org.apache.spark.sql.AnalysisException: expression 'testdata.`a`' is neither present in the group by, nor is it an aggregate function.
```

First, `CheckAnalysis` can't check semantic equality between PythonUDFs.
Second, even we make it possible, runtime exception will be thrown

```
org.apache.spark.sql.catalyst.errors.package$TreeNodeException: Binding attribute, tree: pythonUDF1#8615
...
Cause: java.lang.RuntimeException: Couldn't find pythonUDF1#8615 in [cast(pythonUDF0#8614 as int)#8617,count(b#8599)#8607L]
```

The cause is, `ExtractPythonUDFs` extracts both PythonUDFs in group by and aggregate expression. The PythonUDFs are two different aliases now in the logical aggregate. In runtime, we can't bind the resulting expression in aggregate to its grouping and aggregate attributes.

This patch proposes a rule `ExtractGroupingPythonUDFFromAggregate` to extract PythonUDFs in group by and evaluate them before aggregate. We replace the group by PythonUDF in aggregate expression with aliased result.

The query plan of query `SELECT pyUDF(a + 1), pyUDF(COUNT(b)) FROM testData GROUP BY pyUDF(a + 1)`, like

Wing Yew Poon 80ab19b9fd [SPARK-26329][CORE] Faster polling of executor memory metrics.
## What changes were proposed in this pull request?

Prior to this change, in an executor, on each heartbeat, memory metrics are polled and sent in the heartbeat. The heartbeat interval is 10s by default. With this change, in an executor, memory metrics can optionally be polled in a separate poller at a shorter interval.

For each executor, we use a map of (stageId, stageAttemptId) to (count of running tasks, executor metric peaks) to track what stages are active as well as the per-stage memory metric peaks. When polling the executor memory metrics, we attribute the memory to the active stage(s), and update the peaks. In a heartbeat, we send the per-stage peaks (for stages active at that time), and then reset the peaks. The semantics would be that the per-stage peaks sent in each heartbeat are the peaks since the last heartbeat.

We also keep a map of taskId to memory metric peaks. This tracks the metric peaks during the lifetime of the task. The polling thread updates this as well. At end of a task, we send the peak metric values in the task result. In case of task failure, we send the peak metric values in the `TaskFailedReason`.

We continue to do the stage-level aggregation in the EventLoggingListener.

For the driver, we still only poll on heartbeats. What the driver sends will be the current values of the metrics in the driver at the time of the heartbeat. This is semantically the same as before.

## How was this patch tested?

Unit tests. Manually tested applications on an actual system and checked the event logs; the metrics appear in the SparkListenerTaskEnd and SparkListenerStageExecutorMetrics events.

WeichenXu 26d03b62e2 [SPARK-28366][CORE] Logging in driver when loading single large unsplittable file
## What changes were proposed in this pull request?

Logging in driver when loading single large unsplittable file via `sc.textFile` or csv/json datasouce.
Current condition triggering logging is
* only generate one partition
* file is unsplittable, possible reason is:
   - compressed by unsplittable compression algo such as gzip.
   - multiLine mode in csv/json datasource
   - wholeText mode in text datasource
* file size exceed the config threshold `spark.io.warning.largeFileThreshold` (default value is 1GB)

## How was this patch tested?

Manually test.
Generate one gzip file exceeding 1GB,
```
base64 -b 50 /dev/urandom | head -c 2000000000 > file1.txt
cat file1.txt | gzip > file1.gz
```
then launch spark-shell,

run
```
sc.textFile("file:///path/to/file1.gz").count()
```
Will print log like:
```
WARN HadoopRDD: Loading one large unsplittable file file:/.../f1.gz with only one partition, because the file is compressed by unsplittable compression codec
```

run
```
sc.textFile("file:///path/to/file1.txt").count()
```
Will print log like:
```
WARN HadoopRDD: Loading one large file file:/.../f1.gz with only one partition, we can increase partition numbers by the `minPartitions` argument in method `sc.textFile
```

run
```
spark.read.csv("file:///path/to/file1.gz").count
```
Will print log like:
```
WARN CSVScan: Loading one large unsplittable file file:/.../f1.gz with only one partition, the reason is: the file is compressed by unsplittable compression codec
```

run
```
spark.read.option("multiLine", true).csv("file:///path/to/file1.gz").count
```
Will print log like:
```
WARN CSVScan: Loading one large unsplittable file file:/.../f1.gz with only one partition, the reason is: the csv datasource is set multiLine mode
```

JSON and Text datasource also tested with similar cases.

Maxim Gekk caa23e3efd [SPARK-28459][SQL] Add make_timestamp function
## What changes were proposed in this pull request?

New function `make_timestamp()` takes 6 columns `year`, `month`, `day`, `hour`, `min`, `sec` + optionally `timezone`, and makes new column of the `TIMESTAMP` type. If values in the input columns are `null` or out of valid ranges, the function returns `null`. Valid ranges are:
- `year` - `[1, 9999]`
- `month` - `[1, 12]`
- `day` - `[1, 31]`
- `hour` - `[0, 23]`
- `min` - `[0, 59]`
- `sec` - `[0, 60]`. If the `sec` argument equals to 60, the seconds field is set to 0 and 1 minute is added to the final timestamp.
- `timezone` - an identifier of timezone. Actual database of timezones can be found there: https://www.iana.org/time-zones.

Also constructed timestamp must be valid otherwise `make_timestamp` returns `null`.

The function is implemented similarly to `make_timestamp` in PostgreSQL: https://www.postgresql.org/docs/11/functions-datetime.html to maintain feature parity with it.

Here is an example:
```sql
select make_timestamp(2014, 12, 28, 6, 30, 45.887);
  2014-12-28 06:30:45.887
select make_timestamp(2014, 12, 28, 6, 30, 45.887, 'CET');
  2014-12-28 10:30:45.887
select make_timestamp(2019, 6, 30, 23, 59, 60)
  2019-07-01 00:00:00
```

Returned value has Spark Catalyst type `TIMESTAMP` which is similar to Oracle's `TIMESTAMP WITH LOCAL TIME ZONE` (see https://docs.oracle.com/cd/B28359_01/server.111/b28298/ch4datetime.htm#i1006169) where data is stored in the session time zone, and the time zone offset is not stored as part of the column data. When users retrieve the data, Spark returns it in the session time zone specified by the SQL config `spark.sql.session.timeZone`.

## How was this patch tested?

Added new tests to `DateExpressionsSuite`, and uncommented a test for `make_timestamp` in `pgSQL/timestamp.sql`.

Maxim Gekk a5a5da78cf [SPARK-28471][SQL] Replace yyyy by uuuu in date-timestamp patterns without era
## What changes were proposed in this pull request?

In the PR, I propose to use `uuuu` for years instead of `yyyy` in date/timestamp patterns without the era pattern `G` (https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html). **Parsing/formatting of positive years (current era) will be the same.** The difference is in formatting negative years belong to previous era - BC (Before Christ).

I replaced the `yyyy` pattern by `uuuu` everywhere except:
1. Test, Suite & Benchmark. Existing tests must work as is.
2. `SimpleDateFormat` because it doesn't support the `uuuu` pattern.
3. Comments and examples (except comments related to already replaced patterns).

Before the changes, the year of common era `100` and the year of BC era `-99`, showed similarly as `100`.  After the changes negative years will be formatted with the `-` sign.

Before:
```Scala
scala> Seq(java.time.LocalDate.of(-99, 1, 1)).toDF().show
+----------+
|     value|
+----------+
|0100-01-01|
+----------+
```

Dongjoon Hyun a428f40669 [SPARK-28549][BUILD][CORE][SQL] Use text.StringEscapeUtils instead lang3.StringEscapeUtils
## What changes were proposed in this pull request?

`org.apache.commons.lang3.StringEscapeUtils` was deprecated over two years ago at [LANG-1316](https://issues.apache.org/jira/browse/LANG-1316). There is no bug fixes after that.
```java
/**
 * <p>Escapes and unescapes {code String}s for
 * Java, Java Script, HTML and XML.</p>
 *
 * <p>#ThreadSafe#</p>
 * since 2.0
 * deprecated as of 3.6, use commons-text
 * <a href="https://commons.apache.org/proper/commons-text/javadocs/api-release/org/apache/commons/text/StringEscapeUtils.html">
 * StringEscapeUtils</a> instead
 */
Deprecated
public class StringEscapeUtils {
```

This PR aims to use the latest one from `commons-text` module which has more bug fixes like
[TEXT-100](https://issues.apache.org/jira/browse/TEXT-100), [TEXT-118](https://issues.apache.org/jira/browse/TEXT-118) and [TEXT-120](https://issues.apache.org/jira/browse/TEXT-120) by the following replacement.
```scala
-import org.apache.commons.lang3.StringEscapeUtils
+import org.apache.commons.text.StringEscapeUtils
```

This will add a new dependency to `hadoop-2.7` profile distribution. In `hadoop-3.2` profile, we already have it.
```
+commons-text-1.6.jar
```

Kousuke Saruta 6bc5c6a4e7 [SPARK-28520][SQL] WholeStageCodegen does not work property for LocalTableScanExec
Code is not generated for LocalTableScanExec although proper situations.

If a LocalTableScanExec plan has the direct parent plan which supports WholeStageCodegen,
the LocalTableScanExec plan also should be within a WholeStageCodegen domain.
But code is not generated for LocalTableScanExec and InputAdapter is inserted for now.

```
val df1 = spark.createDataset(1 to 10).toDF
val df2 = spark.createDataset(1 to 10).toDF
val df3 = df1.join(df2, df1("value") === df2("value"))
df3.explain(true)

...

== Physical Plan ==
*(1) BroadcastHashJoin [value#1], [value#6], Inner, BuildRight
:- LocalTableScan [value#1]                                             // LocalTableScanExec is not within a WholeStageCodegen domain
+- BroadcastExchange HashedRelationBroadcastMode(List(cast(input[0, int, false] as bigint)))
   +- LocalTableScan [value#6]
```

```
scala> df3.queryExecution.executedPlan.children.head.children.head.getClass
res4: Class[_ <: org.apache.spark.sql.execution.SparkPlan] = class org.apache.spark.sql.execution.InputAdapter
```

For the current implementation of LocalTableScanExec, codegen is enabled in case `parent` is not null
but `parent` is set in `consume`, which is called after `insertInputAdapter` so it doesn't work as intended.

After applying this cnahge, we can get following plan, which means LocalTableScanExec is within a WholeStageCodegen domain.

```
== Physical Plan ==
*(1) BroadcastHashJoin [value#63], [value#68], Inner, BuildRight
:- *(1) LocalTableScan [value#63]
+- BroadcastExchange HashedRelationBroadcastMode(List(cast(input[0, int, false] as bigint)))
   +- LocalTableScan [value#68]

shahid 485ae6d181 [SPARK-25474][SQL] Support spark.sql.statistics.fallBackToHdfs in data source tables
In case of CatalogFileIndex datasource table, sizeInBytes is always coming as default size in bytes, which is  8.0EB (Even when the user give fallBackToHdfsForStatsEnabled=true) . So, the datasource table which has CatalogFileIndex, always prefer SortMergeJoin, instead of BroadcastJoin, even though the size is below broadcast join threshold.
In this PR, In case of CatalogFileIndex table, if we enable "fallBackToHdfsForStatsEnabled=true", then the computeStatistics  get the sizeInBytes from the hdfs and we get the actual size of the table. Hence, during join operation, when the table size is below broadcast threshold, it will prefer broadCastHashJoin instead of SortMergeJoin.

Added UT

Dongjoon Hyun d943ee0a88 [SPARK-28545][SQL] Add the hash map size to the directional log of ObjectAggregationIterator
## What changes were proposed in this pull request?

`ObjectAggregationIterator` shows a directional info message to increase `spark.sql.objectHashAggregate.sortBased.fallbackThreshold` when the size of the in-memory hash map grows too large and it falls back to sort-based aggregation.
However, we don't know how much we need to increase. This PR adds the size of the current in-memory hash map size to the log message.

**BEFORE**
```
15:21:41.669 Executor task launch worker for task 0 INFO
ObjectAggregationIterator: Aggregation hash map reaches threshold capacity (2 entries), ...
```

**AFTER**
```
15:20:05.742 Executor task launch worker for task 0 INFO
ObjectAggregationIterator: Aggregation hash map size 2 reaches threshold capacity (2 entries), ...
```

## How was this patch tested?

Manual. For example, run `ObjectHashAggregateSuite.scala`'s `typed_count fallback to sort-based aggregation` and search the above message in `target/unit-tests.log`.

##  What changes were proposed in this pull request?

We should add `assume(shouldTestPythonUDFs)`. Maybe it's not a biggie in general but it can matter in other venders' testing base. For instance, if somebody launches a test in a minimal docker image, it might make the tests failed suddenly.

This skipping stuff isn't completely new in our test base. See `TestUtils.testCommandAvailable` for instance.

Liang-Chi Hsieh 558dd23601 [SPARK-28441][SQL][PYTHON] Fix error when non-foldable expression is used in correlated scalar subquery
## What changes were proposed in this pull request?

In SPARK-15370, We checked the expression at the root of the correlated subquery, in order to fix count bug. If a `PythonUDF` in in the checking path, evaluating it causes the failure as we can't statically evaluate `PythonUDF`. The Python UDF test added at SPARK-28277 shows this issue.

If we can statically evaluate the expression, we intercept NULL values coming from the outer join and replace them with the value that the subquery's expression like before, if it is not, we replace them with the `PythonUDF` expression, with statically evaluated parameters.

After this, the last query in `udf-except.sql` which throws `java.lang.UnsupportedOperationException` can be run:

```
SELECT t1.k
FROM   t1
WHERE  t1.v <= (SELECT   udf(max(udf(t2.v)))
                FROM     t2
                WHERE    udf(t2.k) = udf(t1.k))
MINUS
SELECT t1.k
FROM   t1
WHERE  udf(t1.v) >= (SELECT   min(udf(t2.v))
                FROM     t2
                WHERE    t2.k = t1.k)
-- !query 2 schema
struct<k:string>
-- !query 2 output
two
```

Note that this issue is also for other non-foldable expressions, like rand. As like PythonUDF, we can't call `eval` on this kind of expressions in optimization. The evaluation needs to defer to query runtime.

Gengliang Wang b367b323d2 [SPARK-28497][SQL] Disallow upcasting complex data types to string type
## What changes were proposed in this pull request?

In the current implementation. complex types like Array/Map/StructType are allowed to upcast as StringType.
This is not safe casting. We should disallow it.

## How was this patch tested?

Update the existing test case

Closes #25242 from gengliangwang/fixUpCastStringType.

Yuming Wang d67b98ea01 [SPARK-28435][SQL] Support accepting the interval keyword in the schema string
## What changes were proposed in this pull request?

https://github.com/apache/spark/pull/7355 add support casting between IntervalType and StringType for scala interface:
```scala
import org.apache.spark.sql.types._
import org.apache.spark.sql.catalyst.expressions._

Cast(Literal("interval 3 month 1 hours"), CalendarIntervalType).eval()
res0: Any = interval 3 months 1 hours
```
But SQL interface does not support it:
```sql
scala> spark.sql("SELECT CAST('interval 3 month 1 hour' AS interval)").show
org.apache.spark.sql.catalyst.parser.ParseException:
DataType interval is not supported.(line 1, pos 41)

== SQL ==
SELECT CAST('interval 3 month 1 hour' AS interval)
-----------------------------------------^^^

  at org.apache.spark.sql.catalyst.parser.AstBuilder.$anonfun$visitPrimitiveDataType$1(AstBuilder.scala:1931)
  at org.apache.spark.sql.catalyst.parser.ParserUtils$.withOrigin(ParserUtils.scala:108)
  at org.apache.spark.sql.catalyst.parser.AstBuilder.visitPrimitiveDataType(AstBuilder.scala:1909)
  at org.apache.spark.sql.catalyst.parser.AstBuilder.visitPrimitiveDataType(AstBuilder.scala:52)
...
```

This PR add supports accepting the `interval` keyword in the schema string. So that SQL interface can support this feature.

HyukjinKwon b83b7927b3 [SPARK-27234][SS][PYTHON] Use InheritableThreadLocal for current epoch in EpochTracker (to support Python UDFs)
## What changes were proposed in this pull request?

This PR proposes to use `InheritableThreadLocal` instead of `ThreadLocal` for current epoch in `EpochTracker`. Python UDF needs threads to write out to and read it from Python processes and when there are new threads, previously set epoch is lost.

After this PR, Python UDFs can be used at Structured Streaming with the continuous mode.

## How was this patch tested?

The test cases were written on the top of https://github.com/apache/spark/pull/24945.

Wenchen Fan e04f696f7f [SPARK-28346][SQL] clone the query plan between analyzer, optimizer and planner
## What changes were proposed in this pull request?

query plan was designed to be immutable, but sometimes we do allow it to carry mutable states, because of the complexity of the SQL system. One example is `TreeNodeTag`. It's a state of `TreeNode` and can be carried over during copy and transform. The adaptive execution framework relies on it to link the logical and physical plans.

This leads to a problem: when we get `QueryExecution#analyzed`, the plan can be changed unexpectedly because it's mutable. I hit a real issue in https://github.com/apache/spark/pull/25107 : I use `TreeNodeTag` to carry dataset id in logical plans. However, the analyzed plan ends up with many duplicated dataset id tags in different nodes. It turns out that, the optimizer transforms the logical plan and add the tag to more nodes.

For example, the logical plan is `SubqueryAlias(Filter(...))`, and I expect only the `SubqueryAlais` has the dataset id tag. However, the optimizer removes `SubqueryAlias` and carries over the dataset id tag to `Filter`. When I go back to the analyzed plan, both `SubqueryAlias` and `Filter` has the dataset id tag, which breaks my assumption.

Since now query plan is mutable, I think it's better to limit the life cycle of a query plan instance. We can clone the query plan between analyzer, optimizer and planner, so that the life cycle is limited in one stage.

WeichenXu 185c93e701 [SPARK-28431][SQL] Set maximum error message length in CSV datasource's parsing and writing
## What changes were proposed in this pull request?

Fix CSV datasource to throw `com.univocity.parsers.common.TextParsingException` with large size message, which will make log output consume large disk space.
This issue is troublesome when sometimes we need parse CSV with large size column.

This PR proposes to set CSV parser/writer settings by `setErrorContentLength(1000)` to limit the error message length.

## How was this patch tested?

Manually.

```
val s = "a" * 40 * 1000000
Seq(s).toDF.write.mode("overwrite").csv("/tmp/bogdan/es4196.csv")

spark.read .option("maxCharsPerColumn", 30000000) .csv("/tmp/bogdan/es4196.csv").count
```

**Before:**
The thrown message will include error content of about 30MB size (The column size exceed the max value 30MB, so the error content include the whole parsed content, so it is 30MB).

**After:**
The thrown message will include error content like "...aaa...aa" (the number of 'a' is 1024), i.e. limit the content size to be 1024.

Maxim Gekk 2d74f14d74 [SPARK-28432][SQL] Add make_date function
## What changes were proposed in this pull request?

New function `make_date()` takes 3 columns `year`, `month` and `day`, and makes new column of the `DATE` type. If values in the input columns are `null` or out of valid ranges, the function returns `null`. Valid ranges are:
- `year` - `[1, 9999]`
- `month` - `[1, 12]`
- `day` - `[1, 31]`

Also constructed date must be valid otherwise `make_date` returns `null`.

The function is implemented similarly to `make_date` in PostgreSQL: https://www.postgresql.org/docs/11/functions-datetime.html to maintain feature parity with it.

Here is an example:
```sql
select make_date(2013, 7, 15);
2013-07-15
```

## How was this patch tested?

Added new tests to `DateExpressionsSuite`.

## How was this patch tested?

Tested as guided in [SPARK-27921](https://issues.apache.org/jira/browse/SPARK-27921).
Verified pandas & pyarrow versions:
```$python3
Python 3.6.8 (default, Jan 14 2019, 11:02:34)
[GCC 8.0.1 20180414 (experimental) [trunk revision 259383]] on linux

>>> import pandas
>>> import pyarrow
>>> pyarrow.__version__

```
From the sql output it seems that sql statements are evaluated correctly given that udf returns a string and may change results as Null will be returned as None and will be counted in returned values.

mcheah 7ed0088539 [SPARK-27724][SQL] Implement REPLACE TABLE and REPLACE TABLE AS SELECT with V2
## What changes were proposed in this pull request?

Implements the `REPLACE TABLE` and `REPLACE TABLE AS SELECT` logical plans. `REPLACE TABLE` is now a valid operation in spark-sql provided that the tables being modified are managed by V2 catalogs.

This also introduces an atomic mix-in that table catalogs can choose to implement. Table catalogs can now implement `TransactionalTableCatalog`. The semantics of this API are that table creation and replacement can be "staged" and then "committed".

On the execution of `REPLACE TABLE AS SELECT`, `REPLACE TABLE`, and `CREATE TABLE AS SELECT`, if the catalog implements transactional operations, the physical plan will use said functionality. Otherwise, these operations fall back on non-atomic variants. For `REPLACE TABLE` in particular, the usage of non-atomic operations can unfortunately lead to inconsistent state.

## How was this patch tested?

Unit tests - multiple additions to `DataSourceV2SQLSuite`.

Closes #24798 from mccheah/spark-27724.

## How was this patch tested?

Tested as guided in SPARK-27921.
Verified pandas & pyarrow versions:
```$python3
Python 3.6.8 (default, Jan 14 2019, 11:02:34)
[GCC 8.0.1 20180414 (experimental) [trunk revision 259383]] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pandas
>>> import pyarrow
>>> pyarrow.__version__
'0.14.0'
>>> pandas.__version__
'0.24.2'
```
From the sql output it seems that sql statements are evaluated correctly given that udf returns a string and may change results as Null will be returned as None and will be counted in returned values.

Closes #25196 from skonto/group-analytics.sql.
