angerszhu 54d3f6e7ec [SPARK-28982][SQL] Implementation Spark's own GetTypeInfoOperation
### What changes were proposed in this pull request?
 Current Spark Thrift Server return TypeInfo includes
1.  INTERVAL_YEAR_MONTH
2. INTERVAL_DAY_TIME
3. UNION
4. USER_DEFINED

Spark doesn't support INTERVAL_YEAR_MONTH, INTERVAL_YEAR_MONTH, UNION
and won't return USER)DEFINED type.
This PR overwrite GetTypeInfoOperation with SparkGetTypeInfoOperation to exclude types which we don't need.

In hive-1.2.1 Type class is `org.apache.hive.service.cli.Type`
In hive-2.3.x Type class is `org.apache.hadoop.hive.serde2.thrift.Type`

Use ThrifrserverShimUtils to fit version problem and exclude types we don't need

### Why are the changes needed?

We should return type info of Spark's own type info

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

### How was this patch tested?
Manuel test & Added UT

Closes #25694 from AngersZhuuuu/SPARK-28982.

Terry Kim bf43541c92 [SPARK-28856][SQL] Implement SHOW DATABASES for Data Source V2 Tables
### What changes were proposed in this pull request?
Implement the SHOW DATABASES logical and physical plans for data source v2 tables.

### Why are the changes needed?
To support `SHOW DATABASES` SQL commands for v2 tables.

### Does this PR introduce any user-facing change?
`spark.sql("SHOW DATABASES")` will return namespaces if the default catalog is set:
```
+---------------+
|      namespace|
+---------------+
|            ns1|
|      ns1.ns1_1|
|ns1.ns1_1.ns1_2|
+---------------+
```

### How was this patch tested?
Added unit tests to `DataSourceV2SQLSuite`.

Closes #25601 from imback82/show_databases.

sychen 962e330955 [SPARK-26598][SQL] Fix HiveThriftServer2 cannot be modified hiveconf/hivevar variables
### 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.

### Does this PR introduce any user-facing change?
```
cat <<EOF > test.sql

Sean Owen 6378d4bc06 [SPARK-28980][CORE][SQL][STREAMING][MLLIB] Remove most items deprecated in Spark 2.2.0 or earlier, for Spark 3
### What changes were proposed in this pull request?

- Remove SQLContext.createExternalTable and Catalog.createExternalTable, deprecated in favor of createTable since 2.2.0, plus tests of deprecated methods
- Remove HiveContext, deprecated in 2.0.0, in favor of `SparkSession.builder.enableHiveSupport`
- Remove deprecated KinesisUtils.createStream methods, plus tests of deprecated methods, deprecate in 2.2.0
- Remove deprecated MLlib (not Spark ML) linear method support, mostly utility constructors and 'train' methods, and associated docs. This includes methods in LinearRegression, LogisticRegression, Lasso, RidgeRegression. These have been deprecated since 2.0.0
- Remove deprecated Pyspark MLlib linear method support, including LogisticRegressionWithSGD, LinearRegressionWithSGD, LassoWithSGD
- Remove 'runs' argument in KMeans.train() method, which has been a no-op since 2.0.0
- Remove deprecated ChiSqSelector isSorted protected method
- Remove deprecated 'yarn-cluster' and 'yarn-client' master argument in favor of 'yarn' and deploy mode 'cluster', etc

Notes:

- I was not able to remove deprecated DataFrameReader.json(RDD) in favor of DataFrameReader.json(Dataset); the former was deprecated in 2.2.0, but, it is still needed to support Pyspark's .json() method, which can't use a Dataset.
- Looks like SQLContext.createExternalTable was not actually deprecated in Pyspark, but, almost certainly was meant to be? Catalog.createExternalTable was.
- I afterwards noted that the toDegrees, toRadians functions were almost removed fully in SPARK-25908, but Felix suggested keeping just the R version as they hadn't been technically deprecated. I'd like to revisit that. Do we really want the inconsistency? I'm not against reverting it again, but then that implies leaving SQLContext.createExternalTable just in Pyspark too, which seems weird.
- I *kept* LogisticRegressionWithSGD, LinearRegressionWithSGD, LassoWithSGD, RidgeRegressionWithSGD in Pyspark, though deprecated, as it is hard to remove them (still used by StreamingLogisticRegressionWithSGD?) and they are not fully removed in Scala. Maybe should not have been deprecated.

### Why are the changes needed?

Deprecated items are easiest to remove in a major release, so we should do so as much as possible for Spark 3. This does not target items deprecated 'recently' as of Spark 2.3, which is still 18 months old.

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

Yes, in that deprecated items are removed from some public APIs.

### How was this patch tested?

Existing tests.

Marco Gaido 3d6b33a49a [SPARK-28939][SQL] Propagate SQLConf for plans executed by toRdd
### What changes were proposed in this pull request?

The PR proposes to create a custom `RDD` which enables to propagate `SQLConf` also in cases not tracked by SQL execution, as it happens when a `Dataset` is converted to and RDD either using `.rdd` or `.queryExecution.toRdd` and then the returned RDD is used to invoke actions on it.

In this way, SQL configs are effective also in these cases, while earlier they were ignored.

### Why are the changes needed?

Without this patch, all the times `.rdd` or `.queryExecution.toRdd` are used, all the SQL configs set are ignored. An example of a reproducer can be:
```
  withSQLConf(SQLConf.SUBEXPRESSION_ELIMINATION_ENABLED.key, "false") {
    val df = spark.range(2).selectExpr((0 to 5000).map(i => s"id as field_$i"): _*)
    df.createOrReplaceTempView("spark64kb")
    val data = spark.sql("select * from spark64kb limit 10")
    // Subexpression elimination is used here, despite it should have been disabled
    data.describe()
  }
```

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

When a user calls `.queryExecution.toRdd`, a `SQLExecutionRDD` is returned wrapping the `RDD` of the execute. When `.rdd` is used, an additional `SQLExecutionRDD` is present in the hierarchy.

Wenchen Fan abec6d7763 [SPARK-28341][SQL] create a public API for V2SessionCatalog
## What changes were proposed in this pull request?

The `V2SessionCatalog` has 2 functionalities:
1. work as an adapter: provide v2 APIs and translate calls to the `SessionCatalog`.
2. allow users to extend it, so that they can add hooks to apply custom logic before calling methods of the builtin catalog (session catalog).

To leverage the second functionality, users must extend `V2SessionCatalog` which is an internal class. There is no doc to explain this usage.

This PR does 2 things:
1. refine the document of the config `spark.sql.catalog.session`.
2. add a public abstract class `CatalogExtension` for users to write implementations.

TODOs for followup PRs:
1. discuss if we should allow users to completely overwrite the v2 session catalog with a new one.
2. discuss to change the name of session catalog, so that it's less likely to conflict with existing namespace names.

Yuming Wang 4a3a6b66be [SPARK-28637][SQL] Thriftserver support interval type
## What changes were proposed in this pull request?

`bin/spark-shell` support query interval value:
```scala
scala> spark.sql("SELECT interval 3 months 1 hours AS i").show(false)
+-------------------------+
|i                        |
+-------------------------+
|interval 3 months 1 hours|
+-------------------------+
```

But `sbin/start-thriftserver.sh` can't support query interval value:
```sql
0: jdbc:hive2://localhost:10000/default> SELECT interval 3 months 1 hours AS i;
Error: java.lang.IllegalArgumentException: Unrecognized type name: interval (state=,code=0)
```

This PR maps `CalendarIntervalType` to `StringType` for `TableSchema` to make Thriftserver support  query interval value because we do not support `INTERVAL_YEAR_MONTH` type and `INTERVAL_DAY_TIME`:
02c33694c8/sql/hive-thriftserver/v1.2.1/src/main/java/org/apache/hive/service/cli/Type.java (L73-L78)

turbofei d4eca7c99d [SPARK-29000][SQL] Decimal precision overflow when don't allow precision loss
### What changes were proposed in this pull request?

When we set spark.sql.decimalOperations.allowPrecisionLoss to false.

For the sql below, the result will overflow and return null.

Case a:

`select case when 1=2 then 1 else 1.000000000000000000000001 end * 1`
Similar  with the division operation.

This sql below will lost precision.

Case b:

`select case when 1=2 then 1 else 1.000000000000000000000001 end / 1`

Let us check the code of TypeCoercion.scala.

 a75467432e/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/TypeCoercion.scala (L864-L875).

For binaryOperator, if the two operands have differnt datatype, rule ImplicitTypeCasts will find a  common type and cast both operands to common type.

So, for these cases menthioned,  their left operand is Decimal(34, 24) and right operand is Literal.

Their common type is Decimal(34,24), and Literal(1) will be casted to Decimal(34,24).

Then both operands are decimal type and they will be processed by decimalAndDecimal method of DecimalPrecision class.

Let's check the relative code.

a75467432e/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/DecimalPrecision.scala (L123-L153)

When we don't allow precision loss, the result type of multiply operation in case a is Decimal(38, 38), and that of division operation in case b is Decimal(38, 20).

Then the multi operation in case a will overflow and division operation in case b will lost precision.

In this PR, we skip to handle the  binaryOperator if DecimalType operands are involved and rule `DecimalPrecision` will handle it.

### Why are the changes needed?

Data will corrupt without this change.

No.

The PR proposes to split the code for subexpression elimination before inlining the function calls all in the apply method for `Generate[Mutable|Unsafe]Projection`.

maryannxue b2f06608b7 [SPARK-29002][SQL] Avoid changing SMJ to BHJ if the build side has a high ratio of empty partitions
### What changes were proposed in this pull request?
This PR aims to avoid AQE regressions by avoiding changing a sort merge join to a broadcast hash join when the expected build plan has a high ratio of empty partitions, in which case sort merge join can actually perform faster. This PR achieves this by adding an internal join hint in order to let the planner know which side has this high ratio of empty partitions and it should avoid planning it as a build plan of a BHJ. Still, it won't affect the other side if the other side qualifies for a build plan of a BHJ.

### Why are the changes needed?
It is a performance improvement for AQE.

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

Maxim Gekk 67b4329fb0 [SPARK-28690][SQL] Add date_part function for timestamps/dates
## What changes were proposed in this pull request?

In the PR, I propose new function `date_part()`. The function is modeled on the traditional Ingres equivalent to the SQL-standard function `extract`:
```
date_part('field', source)
```
and added for feature parity with PostgreSQL (https://www.postgresql.org/docs/11/functions-datetime.html#FUNCTIONS-DATETIME-EXTRACT).

The `source` can have `DATE` or `TIMESTAMP` type. Supported string values of `'field'` are:
- `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_.
- `century` - the current millennium for given date (or timestamp). The first century starts at 0001-01-01 AD.
- `decade` - the current decade for given date (or timestamp). Actually, this is the year field divided by 10.
- 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.
- `year`, `month`, `day`, `hour`, `minute`, `second`
- `week` - the number of the ISO 8601 week-numbering week of the year. By definition, ISO weeks start on Mondays and the first week of a year contains January 4 of that year.
- `quarter` - the quarter of the year (1 - 4)
- `dayofweek` - the day of the week for date/timestamp (1 = Sunday, 2 = Monday, ..., 7 = Saturday)
- `dow` - the day of the week as Sunday (0) to Saturday (6)
- `isodow` - the day of the week as Monday (1) to Sunday (7)
- `doy` - the day of the year (1 - 365/366)
- `milliseconds` - the seconds field including fractional parts multiplied by 1,000.
- `microseconds` - the seconds field including fractional parts multiplied by 1,000,000.
- `epoch` - the number of seconds since 1970-01-01 00:00:00 local time in microsecond precision.

Here are examples:
```sql
spark-sql> select date_part('year', timestamp'2019-08-12 01:00:00.123456');
2019
spark-sql> select date_part('week', timestamp'2019-08-12 01:00:00.123456');
33
spark-sql> select date_part('doy', timestamp'2019-08-12 01:00:00.123456');
224
```

I changed implementation of `extract` to re-use `date_part()` internally.

## How was this patch tested?

Added `date_part.sql` and regenerated results of `extract.sql`.

Closes #25410 from MaxGekk/date_part.

Takeshi Yamamuro cb0cddffe9 [SPARK-21870][SQL] Split aggregation code into small functions
## What changes were proposed in this pull request?
This pr proposed to split aggregation code into small functions in `HashAggregateExec`. In #18810, we got performance regression if JVMs didn't compile too long functions. I checked and I found the codegen of `HashAggregateExec` frequently goes over the limit when a query has too many aggregate functions (e.g., q66 in TPCDS).

The current master places all the generated aggregation code in a single function. In this pr, I modified the code to assign an individual function for each aggregate function (e.g., `SUM`
 and `AVG`). For example, in a query
`SELECT SUM(a), AVG(a) FROM VALUES(1) t(a)`, the proposed code defines two functions
for `SUM(a)` and `AVG(a)` as follows;

Mukul Murthy 3929d16604 [SPARK-26046][SS] Add StreamingQueryManager.listListeners()
### What changes were proposed in this pull request?

Add a listListeners() method to StreamingQueryManager that lists all StreamingQueryListeners that have been added to that manager.

### Why are the changes needed?

While it's best practice to keep handles on all listeners added, it's still nice to have an API to be able to list what listeners have been added to a StreamingQueryManager.

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

No

### How was this patch tested?

Modified existing unit tests to use the new API instead of using reflection.

Wenchen Fan c81fd0cd61 [SPARK-28974][SQL] centralize the Data Source V2 table capability checks
### What changes were proposed in this pull request?

merge the `V2WriteSupportCheck` and `V2StreamingScanSupportCheck` to one rule: `TableCapabilityCheck`.

### Why are the changes needed?

It's a little confusing to have 2 rules to check DS v2 table capability, while one rule says it checks write and another rule says it checks streaming scan. We can clearly tell it from the rule names that the batch scan check is missing.

It's better to have a centralized place for this check, with a name that clearly says it checks table capability.

maryannxue a7a3935c97 [SPARK-11150][SQL] Dynamic Partition Pruning
### What changes were proposed in this pull request?
This patch implements dynamic partition pruning by adding a dynamic-partition-pruning filter if there is a partitioned table and a filter on the dimension table. The filter is then planned using a heuristic approach:
1. As a broadcast relation if it is a broadcast hash join. The broadcast relation will then be transformed into a reused broadcast exchange by the `ReuseExchange` rule; or
2. As a subquery duplicate if the estimated benefit of partition table scan being saved is greater than the estimated cost of the extra scan of the duplicated subquery; otherwise
3. As a bypassed condition (`true`).

### Why are the changes needed?
This is an important performance feature.

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

### How was this patch tested?
Added UT
- Testing DPP by enabling / disabling the reuse broadcast results feature and / or the subquery duplication feature.
- Testing DPP with reused broadcast results.
- Testing the key iterators on different HashedRelation types.
- Testing the packing and unpacking of the broadcast keys in a LongType.

### What changes were proposed in this pull request?

The Experimental and Evolving annotations are both (like Unstable) used to express that a an API may change. However there are many things in the code that have been marked that way since even Spark 1.x. Per the dev thread, anything introduced at or before Spark 2.3.0 is pretty much 'stable' in that it would not change without a deprecation cycle. Therefore I'd like to remove most of these annotations. And, remove the `:: Experimental ::` scaladoc tag too. And likewise for Python, R.

The changes below can be summarized as:
- Generally, anything introduced at or before Spark 2.3.0 has been unmarked as neither Evolving nor Experimental
- Obviously experimental items like DSv2, Barrier mode, ExperimentalMethods are untouched
- I _did_ unmark a few MLlib classes introduced in 2.4, as I am quite confident they're not going to change (e.g. KolmogorovSmirnovTest, PowerIterationClustering)

It's a big change to review, so I'd suggest scanning the list of _files_ changed to see if any area seems like it should remain partly experimental and examine those.

### Why are the changes needed?

Many of these annotations are incorrect; the APIs are de facto stable. Leaving them also makes legitimate usages of the annotations less meaningful.

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

No.

### How was this patch tested?

Existing tests.

Closes #25558 from srowen/SPARK-28855.

Ryan Blue 3821d75b83 [SPARK-28612][SQL] Add DataFrameWriterV2 API
## What changes were proposed in this pull request?

This adds a new write API as proposed in the [SPIP to standardize logical plans](https://issues.apache.org/jira/browse/SPARK-23521). This new API:

* Uses clear verbs to execute writes, like `append`, `overwrite`, `create`, and `replace` that correspond to the new logical plans.
* Only creates v2 logical plans so the behavior is always consistent.
* Does not allow table configuration options for operations that cannot change table configuration. For example, `partitionedBy` can only be called when the writer executes `create` or `replace`.

Here are a few example uses of the new API:

```scala
df.writeTo("catalog.db.table").append()
df.writeTo("catalog.db.table").overwrite($"date" === "2019-06-01")
df.writeTo("catalog.db.table").overwritePartitions()
df.writeTo("catalog.db.table").asParquet.create()
df.writeTo("catalog.db.table").partitionedBy(days($"ts")).createOrReplace()
df.writeTo("catalog.db.table").using("abc").replace()
```

## How was this patch tested?

Added `DataFrameWriterV2Suite` that tests the new write API. Existing tests for v2 plans.

```

Root cause seems a bug in SBT - it truncates the test name based on the last dot.

https://github.com/sbt/sbt/issues/2949
https://github.com/sbt/sbt/blob/v0.13.18/testing/src/main/scala/sbt/JUnitXmlTestsListener.scala#L71-L79

I tried to find a better way but couldn't find. Therefore, this PR proposes a workaround by appending the test file name into the assert log:

```diff
  [info] - inner-join.sql *** FAILED *** (4 seconds, 306 milliseconds)
+ [info]   inner-join.sql
  [info]   Expected "1	a
  [info]   1	a
  [info]   1	b
  [info]   1[]", but got "1	a
  [info]   1	a
  [info]   1	b
  [info]   1[	b]" Result did not match for query #6
  [info]   SELECT tb.* FROM ta INNER JOIN tb ON ta.a = tb.a AND ta.tag = tb.tag (SQLQueryTestSuite.scala:377)
  [info]   org.scalatest.exceptions.TestFailedException:
  [info]   at org.scalatest.Assertions.newAssertionFailedException(Assertions.scala:528)
```

It will at least prevent us to search full logs to identify which test file is failed by clicking filed test.

Note that this PR does not fully fix the issue but only fix the logs on its failed tests.

### Why are the changes needed?
To debug Jenkins logs easier. Otherwise, we should open full logs and search which test was failed.

### Does this PR introduce any user-facing change?
It will print out the file name of failed tests in Jenkins' test reports.

### How was this patch tested?
Manually tested but Jenkins tests are required in this PR.

Now it at least shows which file it is:

Gengliang Wang 24655583f1 [SPARK-28495][SQL][FOLLOW-UP] Disallow conversions between timestamp and long in ASNI mode
### What changes were proposed in this pull request?

Disallow conversions between `timestamp` type and `long` type in table insertion with ANSI store assignment policy.

### Why are the changes needed?

In the PR https://github.com/apache/spark/pull/25581, timestamp type is allowed to be converted to long type, since timestamp type is represented by long type internally, and both legacy mode and strict mode allows the conversion.

After reconsideration, I think we should disallow it. As per ANSI SQL section "4.4.2 Characteristics of numbers":
> A number is assignable only to sites of numeric type.

In PostgreSQL, the conversion between timestamp and long is also disallowed.

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

Conversion between timestamp and long is disallowed in table insertion with ANSI store assignment policy.

### How was this patch tested?

Matt Hawes 137b20b964 [SPARK-28818][SQL] Respect source column nullability in the arrays created by freqItems()
### What changes were proposed in this pull request?
This PR replaces the hard-coded non-nullability of the array elements returned by `freqItems()` with a nullability that reflects the original schema. Essentially [the functional change](https://github.com/apache/spark/pull/25575/files#diff-bf59bb9f3dc351f5bf6624e5edd2dcf4R122) to the schema generation is:
```
StructField(name + "_freqItems", ArrayType(dataType, false))
```
Becomes:
```
StructField(name + "_freqItems", ArrayType(dataType, originalField.nullable))
```

Respecting the original nullability prevents issues when Spark depends on `ArrayType`'s `containsNull` being accurate. The example that uncovered this is calling `collect()` on the dataframe (see [ticket](https://issues.apache.org/jira/browse/SPARK-28818) for full repro). Though it's likely that there a several places where this could cause a problem.

I've also refactored a small amount of the surrounding code to remove some unnecessary steps and group together related operations.

### Why are the changes needed?
I think it's pretty clear why this change is needed. It fixes a bug that currently prevents users from calling `df.freqItems.collect()` along with potentially causing other, as yet unknown, issues.

### Does this PR introduce any user-facing change?
Nullability of columns when calling freqItems on them is now respected after the change.

### How was this patch tested?
I added a test that specifically tests the carry-through of the nullability as well as explicitly calling `collect()` to catch the exact regression that was observed. I also ran the test against the old version of the code and it fails as expected.

Gengliang Wang 2b24a71fec [SPARK-28495][SQL] Introduce ANSI store assignment policy for table insertion
### What changes were proposed in this pull request?
 Introduce ANSI store assignment policy for table insertion.
With ANSI policy, Spark performs the type coercion of table insertion as per ANSI SQL.

### Why are the changes needed?
In Spark version 2.4 and earlier, when inserting into a table, Spark will cast the data type of input query to the data type of target table by coercion. This can be super confusing, e.g. users make a mistake and write string values to an int column.

In data source V2, by default, only upcasting is allowed when inserting data into a table. E.g. int -> long and int -> string are allowed, while decimal -> double or long -> int are not allowed. The rules of UpCast was originally created for Dataset type coercion. They are quite strict and different from the behavior of all existing popular DBMS. This is breaking change. It is possible that existing queries are broken after 3.0 releases.

Following ANSI SQL standard makes Spark consistent with the table insertion behaviors of popular DBMS like PostgreSQL/Oracle/Mysql.

### Does this PR introduce any user-facing change?
A new optional mode for table insertion.

### How was this patch tested?
Unit test

Closes #25581 from gengliangwang/ANSImode.
