Kent Yao 6fa2fb9eb5 [SPARK-34130][SQL] Impove preformace for char varchar padding and length check with StaticInvoke
### What changes were proposed in this pull request?

This could reduce the `generate.java` size to prevent codegen fallback which causes performance regression.

here is a case from tpcds that could be fixed by this improvement
https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/133964/testReport/org.apache.spark.sql.execution/LogicalPlanTagInSparkPlanSuite/q41/

The original case generate 20K bytes, we are trying to reduce it to less than 8k
### Why are the changes needed?

performance improvement as in the PR benchmark test, the performance  w/ codegen is 2~3x better than w/o codegen.

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

no

### How was this patch tested?

yes, it's a code reflect so the existing ut should be enough

cross-check with https://github.com/apache/spark/pull/31012 where the tpcds shall all pass

benchmark compared with master

Max Gekk a98e77c113 [SPARK-34143][SQL][TESTS] Fix adding partitions to fully partitioned v2 tables
### What changes were proposed in this pull request?
While adding new partition to v2 `InMemoryAtomicPartitionTable`/`InMemoryPartitionTable`, add single row to the table content when the table is fully partitioned.

### Why are the changes needed?
The `ALTER TABLE .. ADD PARTITION` command does not change content of fully partitioned v2 table. For instance, `INSERT INTO` changes table content:
```scala
      sql(s"CREATE TABLE t (p0 INT, p1 STRING) USING _ PARTITIONED BY (p0, p1)")
      sql(s"INSERT INTO t SELECT 1, 'def'")
      sql(s"SELECT * FROM t").show(false)

+---+---+
|p0 |p1 |
+---+---+
|1  |def|
+---+---+
```
but `ALTER TABLE .. ADD PARTITION` doesn't change v2 table content:
```scala
      sql(s"ALTER TABLE t ADD PARTITION (p0 = 0, p1 = 'abc')")
      sql(s"SELECT * FROM t").show(false)

+---+---+
|p0 |p1 |
+---+---+
+---+---+
```

### Does this PR introduce _any_ user-facing change?
No, the changes impact only on tests but for the example above in tests:
```scala
      sql(s"ALTER TABLE t ADD PARTITION (p0 = 0, p1 = 'abc')")
      sql(s"SELECT * FROM t").show(false)

+---+---+
|p0 |p1 |
+---+---+
|0  |abc|
+---+---+
```

### How was this patch tested?
By running the unified tests for `ALTER TABLE .. ADD PARTITION`.

ulysses-you 055124a048 [SPARK-34150][SQL] Strip Null literal.sql in resolve alias
### What changes were proposed in this pull request?

Change null Literal to PrettyAttribute during ResolveAlias.

### Why are the changes needed?

We will convert `Literal(null)` to target data type during analysis. Then the generated alias name will include something like `CAST(NULL AS String)` instead of `NULL`.
```
spark.sql("SELECT RAND(null)").columns

-- before
rand(CAST(NULL AS INT))

-- after
rand(NULL)
```

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

Yes, the default column name maybe changed.

### How was this patch tested?

Add test and pass exists test.

Terry Kim 78893b8dc9 [SPARK-34139][SQL] UnresolvedRelation should retain SQL text position for DDL commands
### What changes were proposed in this pull request?

Currently, there are many DDL commands where the position of the unresolved identifiers are incorrect:
```
scala> sql("CACHE TABLE unknown")
org.apache.spark.sql.AnalysisException: Table or view not found: unknown; line 1 pos 0;
```
, whereas the `pos` should be `12`.

This PR proposes to fix this issue for commands using `UnresolvedRelation`:
```
CACHE TABLE unknown
UNCACHE TABLE unknown
DELETE FROM unknown
UPDATE unknown SET name='abc'
MERGE INTO unknown1 AS target USING unknown2 AS source ON target.col = source.col WHEN MATCHED THEN DELETE
INSERT INTO TABLE unknown SELECT 1
INSERT OVERWRITE TABLE unknown VALUES (1, 'a')
```

### Why are the changes needed?

To fix a bug.

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

Yes, now the above example will print the following:
```
org.apache.spark.sql.AnalysisException: Table or view not found: unknown; line 1 pos 12;
```

### How was this patch tested?

Add a new test.

Max Gekk c3d81fbe79 [SPARK-34060][SQL][FOLLOWUP] Preserve serializability of canonicalized CatalogTable
### What changes were proposed in this pull request?
Replace `toMap` by `map(identity).toMap` while getting canonicalized representation of `CatalogTable`. `CatalogTable` became not serializable after https://github.com/apache/spark/pull/31112 due to usage of `filterKeys`. The workaround was taken from https://github.com/scala/bug/issues/7005.

### Why are the changes needed?
This prevents the errors like:
```
[info]   org.apache.spark.SparkException: Job aborted due to stage failure: Task not serializable: java.io.NotSerializableException: scala.collection.immutable.MapLike$$anon$1
[info]   Cause: java.io.NotSerializableException: scala.collection.immutable.MapLike$$anon$1
```

### Does this PR introduce _any_ user-facing change?
Should not.

Chao Sun b6f46ca297 [SPARK-33212][BUILD] Upgrade to Hadoop 3.2.2 and move to shaded clients for Hadoop 3.x profile
### What changes were proposed in this pull request?

This:
1. switches Spark to use shaded Hadoop clients, namely hadoop-client-api and hadoop-client-runtime, for Hadoop 3.x.
2. upgrade built-in version for Hadoop 3.x to Hadoop 3.2.2

Note that for Hadoop 2.7, we'll still use the same modules such as hadoop-client.

In order to still keep default Hadoop profile to be hadoop-3.2, this defines the following Maven properties:

```
hadoop-client-api.artifact
hadoop-client-runtime.artifact
hadoop-client-minicluster.artifact
```

which default to:
```
hadoop-client-api
hadoop-client-runtime
hadoop-client-minicluster
```
but all switch to `hadoop-client` when the Hadoop profile is hadoop-2.7. A side affect from this is we'll import the same dependency multiple times. For this I have to disable Maven enforcer `banDuplicatePomDependencyVersions`.

Besides above, there are the following changes:
- explicitly add a few dependencies which are imported via transitive dependencies from Hadoop jars, but are removed from the shaded client jars.
- removed the use of `ProxyUriUtils.getPath` from `ApplicationMaster` which is a server-side/private API.
- modified `IsolatedClientLoader` to exclude `hadoop-auth` jars when Hadoop version is 3.x. This change should only matter when we're not sharing Hadoop classes with Spark (which is _mostly_ used in tests).

### Why are the changes needed?

Hadoop 3.2.2 is released with new features and bug fixes, so it's good for the Spark community to adopt it. However, latest Hadoop versions starting from Hadoop 3.2.1 have upgraded to use Guava 27+. In order to resolve Guava conflicts, this takes the approach by switching to shaded client jars provided by Hadoop. This also has the benefits of avoid pulling other 3rd party dependencies from Hadoop side so as to avoid more potential future conflicts.

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

When people use Spark with `hadoop-provided` option, they should make sure class path contains `hadoop-client-api` and `hadoop-client-runtime` jars. In addition, they may need to make sure these jars appear before other Hadoop jars in the order. Otherwise, classes may be loaded from the other non-shaded Hadoop jars and cause potential conflicts.

### How was this patch tested?

Relying on existing tests.

On the read-side, we should respect the original data instead of trimming it first.

It brings extra overhead on the code-gen code side, trimming and padding for the same field, and it's also unnecessary and a bug

Kousuke Saruta bec80d7eec [SPARK-34101][SQL] Make spark-sql CLI configurable for the behavior of printing header by SET command
### What changes were proposed in this pull request?

This PR introduces a new property `spark.sql.cli.print.header` to let users change the behavior of printing header for spark-sql CLI by SET command.

### Why are the changes needed?

Like Hive CLI, spark-sql CLI accepts `hive.cli.print.header` property and we can change the behavior of printing header.
But spark-sql CLI doesn't allow users to change Hive specific configurations dynamically by SET command.
So, it's better to support the way to change the behavior by SET command.

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

Yes. Users can dynamically change the behavior by SET command.

### How was this patch tested?

I confirmed with the following commands/queries.
```
spark-sql> select (1) as a, (2) as b, (3) as c, (4) as d;
1	2	3	4
Time taken: 3.218 seconds, Fetched 1 row(s)
spark-sql> set spark.sql.cli.print.header=true;
key	value
spark.sql.cli.print.header	true
Time taken: 1.506 seconds, Fetched 1 row(s)
spark-sql> select (1) as a, (2) as b, (3) as c, (4) as d;
a	b	c	d
1	2	3	4
Time taken: 0.79 seconds, Fetched 1 row(s)
```

Closes #31173 from sarutak/spark-sql-print-header.

ulysses-you 92e5cfd58d [SPARK-33989][SQL] Strip auto-generated cast when using Cast.sql
### What changes were proposed in this pull request?

This PR aims to strip auto-generated cast. The main logic is:
1. Add tag if Cast is specified by user.
2. Wrap `PrettyAttribute` in usePrettyExpression.

### Why are the changes needed?

Make sql consistent with dsl. Here is an inconsistent example before this PR:

```
-- output field name: FLOOR(1)
spark.emptyDataFrame.select(floor(lit(1)))

-- output field name: FLOOR(CAST(1 AS DOUBLE))
spark.sql("select floor(1)")
```

Note that, we don't remove the `Cast` so the auto-generated `Cast` can still work. The only changed place is `usePrettyExpression`, we use `PrettyAttribute` replace `Cast` to give a better sql string.

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

Yes, the default field name may change.

### How was this patch tested?

Add test and pass exists test.

Closes #31034 from ulysses-you/SPARK-33989.

We need to look recursively into children to find char/varchars.

In this PR,  we try to resolve the full attributes including the original `Aggregate` expressions and the candidates in `SortOrder` together, then use the new re-resolved `Aggregate` expressions to determine which candidate in the `SortOrder` shall be pushed. This can avoid mismatch for the same attributes w/o this change, as the expressions returned by `executeSameContext` will change when `PaddingAndLengthCheckForCharVarchar` takes effects. W/ this change, the expressions can be matched correctly.

For those unmatched, w need to look recursively into children to find char/varchars instead of the expression itself only.

Liang-Chi Hsieh 0bcbafb4b8 [SPARK-34002][SQL] Fix the usage of encoder in ScalaUDF
### What changes were proposed in this pull request?

This patch fixes few issues when using encoders to serialize input/output in `ScalaUDF`.

### Why are the changes needed?

This fixes a bug when using encoders in Scala UDF. First, the output data type should be corrected to the corresponding data type of the object serializer. Second, `catalystConverter` should not serialize `Option[_]` as the ordinary row because in `ScalaUDF` case it is serialized to a column, not the top-level row. Otherwise, there will be a redundant `value` struct wrapping the serialized `Option[_]` object.

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

Yes, fixing a bug of `ScalaUDF`.

### How was this patch tested?

Unit test.

Max Gekk d97e99157e [SPARK-34060][SQL] Fix Hive table caching while updating stats by ALTER TABLE .. DROP PARTITION
### What changes were proposed in this pull request?
Fix canonicalisation of `HiveTableRelation` by normalisation of `CatalogTable`, and exclude table stats and temporary fields from the canonicalized plan.

### Why are the changes needed?
This fixes the issue demonstrated by the example below:
```scala
scala> spark.conf.set("spark.sql.statistics.size.autoUpdate.enabled", true)
scala> sql(s"CREATE TABLE tbl (id int, part int) USING hive PARTITIONED BY (part)")
scala> sql("INSERT INTO tbl PARTITION (part=0) SELECT 0")
scala> sql("INSERT INTO tbl PARTITION (part=1) SELECT 1")
scala> sql("CACHE TABLE tbl")
scala> sql("SELECT * FROM tbl").show(false)
+---+----+
|id |part|
+---+----+
|0  |0   |
|1  |1   |
+---+----+

scala> spark.catalog.isCached("tbl")
scala> sql("ALTER TABLE tbl DROP PARTITION (part=0)")
scala> spark.catalog.isCached("tbl")
res19: Boolean = false
```
`ALTER TABLE .. DROP PARTITION` must keep the table in the cache.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the drop partition command keeps the table in the cache while updating table stats:
```scala
scala> sql("ALTER TABLE tbl DROP PARTITION (part=0)")
scala> spark.catalog.isCached("tbl")
res19: Boolean = true
```

### How was this patch tested?
By running new UT in `AlterTableDropPartitionSuite`.

Terry Kim 8391a4a687 [SPARK-34057][SQL] UnresolvedTableOrView should retain SQL text position for DDL commands
### What changes were proposed in this pull request?

Currently, there are many DDL commands where the position of the unresolved identifiers are incorrect:
```
scala> sql("DROP TABLE unknown")
org.apache.spark.sql.AnalysisException: Table or view not found: unknown; line 1 pos 0;
```
, whereas the `pos` should be `11`.

This PR proposes to fix this issue for commands using `UnresolvedTableOrView`:
```
DROP TABLE unknown
DESCRIBE TABLE unknown
ANALYZE TABLE unknown COMPUTE STATISTICS
ANALYZE TABLE unknown COMPUTE STATISTICS FOR COLUMNS col
ANALYZE TABLE unknown COMPUTE STATISTICS FOR ALL COLUMNS
SHOW CREATE TABLE unknown
REFRESH TABLE unknown
SHOW COLUMNS FROM unknown
SHOW COLUMNS FROM unknown IN db
ALTER TABLE unknown RENAME TO t
ALTER VIEW unknown RENAME TO v
```

### Why are the changes needed?

To fix a bug.

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

Yes, now the above example will print the following:
```
org.apache.spark.sql.AnalysisException: Table or view not found: unknown; line 1 pos 11;
```

### How was this patch tested?

Add a new test.

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

This PR is basically a followup of https://github.com/apache/spark/pull/14332.
Calling `map` alone might leave it not executed due to lazy evaluation, e.g.)

```

scala> foo.map(println)
1
2
3
res0: Seq[Unit] = List((), (), ())

scala> foo.view.map(println)
res1: scala.collection.SeqView[Unit,Seq[_]] = SeqViewM(...)

scala> foo.view.foreach(println)
1
2

We should better use `foreach` to make sure it's executed where the output is unused or `Unit`.

### Why are the changes needed?

To prevent the potential issues by not executing `map`.

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

No, the current codes look not causing any problem for now.

### How was this patch tested?

I found these item by running IntelliJ inspection, double checked one by one, and fixed them. These should be all instances across the codebase ideally.

ulysses-you 48cd11c483 [SPARK-34030][SQL] Fold RepartitionByExpression num partition should at Optimizer
### What changes were proposed in this pull request?

Move `RepartitionByExpression` fold partition number code to a new rule at `Optimizer`.

### Why are the changes needed?

We meet some ploblem when backport SPARK-33806. It is because the UnresolvedFunction.foldable will throw a exception. It's ok with master branch, but it's better to do it at Optimizer. Some reason:

1. It's not always safe to call Expression.foldable before analysis.
2. fold num partition to 1 more like a optimize behavior.

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

No.

### How was this patch tested?

Add test.

Anton Okolnychyi 6b34745cb9 [SPARK-34049][SS] DataSource V2: Use Write abstraction in StreamExecution
### What changes were proposed in this pull request?

This PR makes `StreamExecution` use the `Write` abstraction introduced in SPARK-33779.

Note: we will need separate plans for streaming writes in order to support the required distribution and ordering in SS. This change only migrates to the `Write` abstraction.

### Why are the changes needed?

These changes prevent exceptions from data sources that implement only the `build` method in `WriteBuilder`.

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

No.

### How was this patch tested?

Kousuke Saruta 0781ed4f5b [MINOR][SQL][TESTS] Fix the incorrect unicode escape test in ParserUtilsSuite
### What changes were proposed in this pull request?

This PR fixes an incorrect unicode literal test in `ParserUtilsSuite`.
In that suite, string literals in queries have unicode escape characters like `\u7328` but the backslash should be escaped because
the queriy strings are given as Java strings.

### Why are the changes needed?

Correct the test.

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

No.

### How was this patch tested?

Run `ParserUtilsSuite` and it passed.

Max Gekk 157b72ac9f [SPARK-33591][SQL] Recognize null in partition spec values
### What changes were proposed in this pull request?
1. Recognize `null` while parsing partition specs, and put `null` instead of `"null"` as partition values.
2. For V1 catalog: replace `null` by `__HIVE_DEFAULT_PARTITION__`.
3. For V2 catalogs: pass `null` AS IS, and let catalog implementations to decide how to handle `null`s as partition values in spec.

### Why are the changes needed?
Currently, `null` in partition specs is recognized as the `"null"` string which could lead to incorrect results, for example:
```sql
spark-sql> CREATE TABLE tbl5 (col1 INT, p1 STRING) USING PARQUET PARTITIONED BY (p1);
spark-sql> INSERT INTO TABLE tbl5 PARTITION (p1 = null) SELECT 0;
spark-sql> SELECT isnull(p1) FROM tbl5;
false
```
Even we inserted a row to the partition with the `null` value, **the resulted table doesn't contain `null`**.

### Does this PR introduce _any_ user-facing change?
Yes. After the changes, the example above works as expected:
```sql
spark-sql> SELECT isnull(p1) FROM tbl5;
true
```

### How was this patch tested?
1. By running the affected test suites `SQLQuerySuite`, `AlterTablePartitionV2SQLSuite` and `v1/ShowPartitionsSuite`.
2. Compiling by Scala 2.13:
```
$  ./dev/change-scala-version.sh 2.13
$ ./build/sbt -Pscala-2.13 compile
```

Kent Yao 0f8e5dd445 [SPARK-34003][SQL] Fix Rule conflicts between PaddingAndLengthCheckForCharVarchar and ResolveAggregateFunctions
### What changes were proposed in this pull request?

ResolveAggregateFunctions is a hacky rule and it calls `executeSameContext` to generate a `resolved agg` to determine which unresolved sort attribute should be pushed into the agg. However, after we add the PaddingAndLengthCheckForCharVarchar rule which will rewrite the query output, thus, the `resolved agg` cannot match original attributes anymore.

It causes some dissociative sort attribute to be pushed in and fails the query

yangjie01 26b603992c [SPARK-34028][SQL] Cleanup "unreachable code" compilation warning
### What changes were proposed in this pull request?
There is one compilation warning as follow:

```

This compilation warning is due to `NoSuchPermanentFunctionException` is sub-class of `AnalysisException` and if there is `NoSuchPermanentFunctionException` be thrown out,  it will be catch by `case _: AnalysisException => failFunctionLookup(name)`,  so `case _: NoSuchPermanentFunctionException => failFunctionLookup(name)` is `unreachable code`.

yangjie01 45a4ff8e54 [SPARK-33948][SQL] Fix CodeGen error of MapObjects.doGenCode method in Scala 2.13
### What changes were proposed in this pull request?
`MapObjects.doGenCode` method will generate wrong code when `inputDataType` is `ArrayBuffer`.

For example `encode/decode for Tuple2: (ArrayBuffer[(String, String)],ArrayBuffer((a,b))) (codegen path)` in `ExpressionEncoderSuite`, the error generated code part as follow:

```
/* 126 */   private scala.collection.mutable.ArrayBuffer MapObjects_0(InternalRow i) {
/* 127 */     boolean isNull_4 = i.isNullAt(1);
/* 128 */     ArrayData value_4 = isNull_4 ?
/* 129 */     null : (i.getArray(1));
/* 130 */     scala.collection.mutable.ArrayBuffer value_3 = null;
/* 131 */
/* 132 */     if (!isNull_4) {
/* 133 */
/* 134 */       int dataLength_0 = value_4.numElements();
/* 135 */
/* 136 */       scala.Tuple2[] convertedArray_0 = null;
/* 137 */       convertedArray_0 = new scala.Tuple2[dataLength_0];
/* 138 */
/* 139 */
/* 140 */       int loopIndex_0 = 0;
/* 141 */
/* 142 */       while (loopIndex_0 < dataLength_0) {
/* 143 */         value_MapObject_lambda_variable_1 = (InternalRow) (value_4.getStruct(loopIndex_0, 2));
/* 144 */         isNull_MapObject_lambda_variable_1 = value_4.isNullAt(loopIndex_0);
/* 145 */
/* 146 */         boolean isNull_5 = false;
/* 147 */         scala.Tuple2 value_5 = null;
/* 148 */         if (!false && isNull_MapObject_lambda_variable_1) {
/* 149 */
/* 150 */           isNull_5 = true;
/* 151 */           value_5 = ((scala.Tuple2)null);
/* 152 */         } else {
/* 153 */           scala.Tuple2 value_13 = NewInstance_0(i);
/* 154 */           isNull_5 = false;
/* 155 */           value_5 = value_13;
/* 156 */         }
/* 157 */         if (isNull_5) {
/* 158 */           convertedArray_0[loopIndex_0] = null;
/* 159 */         } else {
/* 160 */           convertedArray_0[loopIndex_0] = value_5;
/* 161 */         }
/* 162 */
/* 163 */         loopIndex_0 += 1;
/* 164 */       }
/* 165 */
/* 166 */       value_3 = new org.apache.spark.sql.catalyst.util.GenericArrayData(convertedArray_0);
/* 167 */     }
/* 168 */     globalIsNull_0 = isNull_4;
/* 169 */     return value_3;
/* 170 */   }

```

Line 166 in generated code try to assign `GenericArrayData`  to `value_3(ArrayBuffer)` because `ArrayBuffer` type can't match `s.c.i.Seq` branch in Scala 2.13 in `MapObjects.doGenCode` method now.

So this pr change to use `s.c.Seq` instead of `Seq` alias to let `ArrayBuffer` type can enter  the same branch as Scala 2.12.

After this pr the generate code when `inputDataType` is `ArrayBuffer` as follow:

```
/* 126 */   private scala.collection.mutable.ArrayBuffer MapObjects_0(InternalRow i) {
/* 127 */     boolean isNull_4 = i.isNullAt(1);
/* 128 */     ArrayData value_4 = isNull_4 ?
/* 129 */     null : (i.getArray(1));
/* 130 */     scala.collection.mutable.ArrayBuffer value_3 = null;
/* 131 */
/* 132 */     if (!isNull_4) {
/* 133 */
/* 134 */       int dataLength_0 = value_4.numElements();
/* 135 */
/* 136 */       scala.collection.mutable.Builder collectionBuilder_0 = scala.collection.mutable.ArrayBuffer$.MODULE$.newBuilder();
/* 137 */       collectionBuilder_0.sizeHint(dataLength_0);
/* 138 */
/* 139 */
/* 140 */       int loopIndex_0 = 0;
/* 141 */
/* 142 */       while (loopIndex_0 < dataLength_0) {
/* 143 */         value_MapObject_lambda_variable_1 = (InternalRow) (value_4.getStruct(loopIndex_0, 2));
/* 144 */         isNull_MapObject_lambda_variable_1 = value_4.isNullAt(loopIndex_0);
/* 145 */
/* 146 */         boolean isNull_5 = false;
/* 147 */         scala.Tuple2 value_5 = null;

/* 154 */           isNull_5 = false;
/* 155 */           value_5 = value_13;
/* 156 */         }

/* 163 */         loopIndex_0 += 1;
/* 164 */       }
/* 165 */
/* 166 */       value_3 = (scala.collection.mutable.ArrayBuffer) collectionBuilder_0.result();
/* 167 */     }

The implementation in `JoinReorderDP.betterThan` does not match this documentaiton:
```
def betterThan(other: JoinPlan, conf: SQLConf): Boolean = {
      if (other.planCost.card == 0 || other.planCost.size == 0) {
        false
      } else {
        val relativeRows = BigDecimal(this.planCost.card) / BigDecimal(other.planCost.card)
        val relativeSize = BigDecimal(this.planCost.size) / BigDecimal(other.planCost.size)
        relativeRows * conf.joinReorderCardWeight +
          relativeSize * (1 - conf.joinReorderCardWeight) < 1
      }
    }
```

This different implementation has an unfortunate consequence:
given two plans A and B, both A betterThan B and B betterThan A might give the same results. This happes when one has many rows with small sizes and other has few rows with large sizes.

A example values, that have this fenomen with the default weight value (0.7):
A.card = 500, B.card = 300
A.size = 30, B.size = 80
Both A betterThan B and B betterThan A would have score above 1 and would return false.

This happens with several of the TPCDS queries.

The new implementation does not have this behavior.

Kent Yao f0ffe0cd65 [SPARK-33992][SQL] override transformUpWithNewOutput to add allowInvokingTransformsInAnalyzer
### What changes were proposed in this pull request?

In https://github.com/apache/spark/pull/29643, we move  the plan rewriting methods to QueryPlan. we need to override transformUpWithNewOutput to add allowInvokingTransformsInAnalyzer
 because it and resolveOperatorsUpWithNewOutput are called in the analyzer.
For example,

PaddingAndLengthCheckForCharVarchar could fail query when resolveOperatorsUpWithNewOutput
with
```logtalk

Chongguang LIU 976e97a80d [SPARK-33794][SQL] NextDay expression throw runtime IllegalArgumentException when receiving invalid input under ANSI mode
### What changes were proposed in this pull request?

Instead of returning NULL, the next_day function throws runtime IllegalArgumentException when ansiMode is enable and receiving invalid input of the dayOfWeek parameter.

### Why are the changes needed?

For ansiMode.

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

Yes.
When spark.sql.ansi.enabled = true, the next_day function will throw IllegalArgumentException when receiving invalid input of the dayOfWeek parameter.
When spark.sql.ansi.enabled = false, same behaviour as before.

### How was this patch tested?

Ansi mode is tested with existing tests.
End-to-end tests have been added.

tanel.kiis@gmail.com bb6d6b5602 [SPARK-33964][SQL] Combine distinct unions in more cases
### What changes were proposed in this pull request?

Added the `RemoveNoopOperators` rule to optimization batch `Union`.  Also made sure that the `RemoveNoopOperators` would be idempotent.

### Why are the changes needed?

In several TPCDS queries the `CombineUnions` rule does not manage to combine unions, because they have noop `Project`s between them.
The `Project`s will be removed by `RemoveNoopOperators`, but by then `ReplaceDistinctWithAggregate` has been applied and there are aggregates between the unions. Adding a copy of `RemoveNoopOperators` earlier in the optimization chain allows `CombineUnions` to work on more queries.

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

No

New UTs and the output of `PlanStabilitySuite`

### What changes were proposed in this pull request?
Remove partition data by `ALTER TABLE .. DROP PARTITION` in V2 table catalog used in tests.

### Why are the changes needed?
This is a bug fix. Before the fix, `ALTER TABLE .. DROP PARTITION` does not remove the data belongs to the dropped partition. As a consequence of that, the `select` query returns removed data.

This PR proposes to implement `DESCRIBE COLUMN` for v2 tables.

Note that `isExnteded` option is not implemented in this PR.

### Why are the changes needed?

Parity with v1 tables.

Liang-Chi Hsieh 963c60fe49 [SPARK-33955][SS] Add latest offsets to source progress
### What changes were proposed in this pull request?

This patch proposes to add latest offset to source progress for streaming queries.

### Why are the changes needed?

Currently we record start and end offsets per source in streaming process. Latest offset is an important information for streaming process but the progress lacks of this info. We can use it to track the process lag and adjust streaming queries. We should add latest offset to source progress.

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

Yes, for new metric about latest source offset in source progress.
