### What changes were proposed in this pull request?
This switches Spark to use shaded Hadoop clients, namely hadoop-client-api and hadoop-client-runtime, for Hadoop 3.x. 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?
This serves two purposes:
- to unblock Spark from upgrading to Hadoop 3.2.2/3.3.0+. Latest Hadoop versions have upgraded to use Guava 27+ and in order to adopt the latest Hadoop versions in Spark, we'll need to resolve the Guava conflicts. This takes the approach by switching to shaded client jars provided by Hadoop.
- avoid pulling 3rd party dependencies from Hadoop and avoid 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.

### What changes were proposed in this pull request?
1. Set the default value for the SQL configs `spark.sql.legacy.parquet.int96RebaseModeInWrite` and `spark.sql.legacy.parquet.int96RebaseModeInRead` to `EXCEPTION`.
2. Update the SQL migration guide.
### Why are the changes needed?
Current default value `LEGACY` may lead to shifting timestamps in read or in write. We should leave the decision about rebasing to users.
### Does this PR introduce _any_ user-facing change?
Yes
### How was this patch tested?

### What changes were proposed in this pull request?
Postgres and MSSQL connection providers are not able to get custom `appEntry` because under some circumstances the driver is wrapped with `DriverWrapper`. Such case is not handled in the mentioned providers. In this PR I've added this edge case handling by passing unwrapped `Driver` from `JdbcUtils`.

### What changes were proposed in this pull request?
1. Add the SQL config `spark.sql.legacy.parquet.int96RebaseModeInWrite` to control timestamps rebasing in saving them as INT96. It supports the same set of values as `spark.sql.legacy.parquet.datetimeRebaseModeInWrite` but the default value is `LEGACY` to preserve backward compatibility with Spark <= 3.0.
2. Write the metadata key `org.apache.spark.int96NoRebase` to parquet files if the files are saved with `spark.sql.legacy.parquet.int96RebaseModeInWrite` isn't set to `LEGACY`.
3. Add the SQL config `spark.sql.legacy.parquet.datetimeRebaseModeInRead` to control loading INT96 timestamps when parquet metadata doesn't have enough info (the `org.apache.spark.int96NoRebase` tag) about parquet writer - either INT96 was written by Proleptic Gregorian system or some Julian one.
4. Modified Vectorized and Parquet-mr Readers to support loading/saving INT96 timestamps w/o rebasing depending on SQL config and the metadata tag:
- **No rebasing** in testing when the SQL config `spark.test.forceNoRebase` is set to `true`
- **No rebasing** if parquet metadata contains the tag `org.apache.spark.int96NoRebase`. This is the case when parquet files are saved by Spark >= 3.1 with `spark.sql.legacy.parquet.datetimeRebaseModeInWrite` is set to `CORRECTED`, or saved by other systems with the tag `org.apache.spark.int96NoRebase`.
- **With rebasing** if parquet files saved by Spark (any versions) without the metadata tag `org.apache.spark.int96NoRebase`.
- Rebasing depend on the SQL config `spark.sql.legacy.parquet.datetimeRebaseModeInRead` if there are no metadata tags `org.apache.spark.version` and `org.apache.spark.int96NoRebase`.
New SQL configs are added instead of re-using existing `spark.sql.legacy.parquet.datetimeRebaseModeInWrite` and `spark.sql.legacy.parquet.datetimeRebaseModeInRead` because of:
- To allow users have different modes for INT96 and for TIMESTAMP_MICROS (MILLIS). For example, users might want to save INT96 as LEGACY but TIMESTAMP_MICROS as CORRECTED.
- To have different modes for INT96 and DATE in load (or in save).
- To be backward compatible with Spark 2.4. For now, `spark.sql.legacy.parquet.datetimeRebaseModeInWrite/Read` are set to `EXCEPTION` by default.
### Why are the changes needed?
1. Parquet spec says that INT96 must be stored as Julian days (see https://github.com/apache/parquet-format/pull/49). This doesn't mean that a reader ( or a writer) is based on the Julian calendar. So, rebasing from Proleptic Gregorian to Julian calendar can be not needed.
2. Rebasing from/to Julian calendar can loose information because dates in one calendar don't exist in another one. Like 1582-10-04..1582-10-15 exist in Proleptic Gregorian calendar but not in the hybrid calendar (Julian + Gregorian), and visa versa, Julian date 1000-02-29 doesn't exist in Proleptic Gregorian calendar. We should allow users to save timestamps without loosing such dates (rebasing shifts such dates to the next valid date).
3. It would also make Spark compatible with other systems such as Impala and newer versions of Hive that write proleptic Gregorian based INT96 timestamps.
### Does this PR introduce _any_ user-facing change?
It can when `spark.sql.legacy.parquet.int96RebaseModeInWrite` is set non-default value `LEGACY`.
### How was this patch tested?
- Added a test to check the metadata key `org.apache.spark.int96NoRebase`
- By `ParquetIOSuite`

### What changes were proposed in this pull request?
Currently, actual non-dynamic partition pruning is executed in the optimizer phase (PruneFileSourcePartitions) if an input relation has a catalog file index. The current code assumes the same partition filters are generated again in FileSourceStrategy and passed into FileSourceScanExec. FileSourceScanExec uses the partition filters when listing files, but these non-dynamic partition filters do nothing because unnecessary partitions are already pruned in advance, so the filters are mainly used for explain output in this case. If a WHERE clause has DNF-ed predicates, FileSourceStrategy cannot extract the same filters with PruneFileSourcePartitions and then PartitionFilters is not shown in explain output.
This patch proposes to extract partition filters in FileSourceStrategy and HiveStrategy with `extractPredicatesWithinOutputSet` added in https://github.com/apache/spark/pull/29101/files#diff-6be42cfa3c62a7536b1eb1d6447c073c again, then It will show the partially pushed down partition filter in explain().
### Why are the changes needed?

### What changes were proposed in this pull request?
This patch proposes to add more optimization to `UpdateFields` expression chain. And optimize `UpdateFields` early in analysis phase.
### Why are the changes needed?
`UpdateFields` can manipulate complex nested data, but using `UpdateFields` can easily create inefficient expression chain. We should optimize it further.
Because when manipulating deeply nested schema, the `UpdateFields` expression tree could be too complex to analyze, this change optimizes `UpdateFields` early in analysis phase.

### What changes were proposed in this pull request?
This patch proposes to add a config we can control fast-fail behavior in FileFormatWriter and set it false by default.
### Why are the changes needed?
In SPARK-29649, we catch `FileAlreadyExistsException` in `FileFormatWriter` and fail fast for the task set to prevent task retry.
Due to latest discussion, it is important to be able to keep original behavior that is to retry tasks even `FileAlreadyExistsException` is thrown, because `FileAlreadyExistsException` could be recoverable in some cases.
We are going to add a config we can control this behavior and set it false for fast-fail by default.
### Does this PR introduce _any_ user-facing change?
Yes. By default the task in FileFormatWriter will retry even if `FileAlreadyExistsException` is thrown. This is the behavior before Spark 3.0. User can control fast-fail behavior by enabling it.

### What changes were proposed in this pull request?
SPARK-29358 added support for `unionByName` to work when the two datasets didn't necessarily have the same schema, but it does not work with nested columns like structs. This patch adds the support to work with struct columns.
The behavior before this PR:
```scala
scala> val df1 = spark.range(1).selectExpr("id c0", "named_struct('c', id + 1, 'b', id + 2, 'a', id + 3) c1")
scala> val df2 = spark.range(1).selectExpr("id c0", "named_struct('c', id + 1, 'b', id + 2) c1")
scala> df1.unionByName(df2, true).printSchema

+- Range (0, 1, step=1, splits=Some(12))
```
The behavior after this PR:
```scala
scala> df1.unionByName(df2, true).printSchema
root
|-- c0: long (nullable = false)
|-- c1: struct (nullable = false)
| |-- a: long (nullable = true)

### Why are the changes needed?
The `allowMissingColumns` of `unionByName` is a feature allowing merging different schema from two datasets when unioning them together. Nested column support makes the feature more general and flexible for usage.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
Current solution in build file to enable build failure on compilation warnings with exclusion of deprecation ones is not portable after SBT version 1.3.13 (build import fails with compilation error with SBT 1.4) and could be replaced with more robust and maintainable, especially since Scala 2.13.2 with similar built-in functionality.
Additionally, warnings were fixed to pass the build, with as few changes as possible:
warnings in 2.12 compilation fixed in code,
warnings in 2.13 compilation covered by configuration to be addressed separately
### Why are the changes needed?
Unblocks upgrade to SBT after 1.3.13.
Enhances build file maintainability.
Allows fine tune of warnings configuration in scope of Scala 2.13 compilation.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
I currently have unquoted column names in alter table, e.g. ```ALTER TABLE "test"."alt_table" DROP COLUMN c1```
should change to quoted column name ```ALTER TABLE "test"."alt_table" DROP COLUMN "c1"```
### Why are the changes needed?
We should always use quoted identifiers in JDBC SQLs, e.g. ```CREATE TABLE "test"."abc" ("col" INTEGER ) ``` or ```INSERT INTO "test"."abc" ("col") VALUES (?)```. Using unquoted column name in alterTable causes problems, for example:
```
sql("CREATE TABLE h2.test.alt_table (c1 INTEGER, c2 INTEGER) USING _")
sql("ALTER TABLE h2.test.alt_table DROP COLUMN c1")
org.apache.spark.sql.AnalysisException: Failed table altering: test.alt_table;
......
Caused by: org.h2.jdbc.JdbcSQLException: Column "C1" not found; SQL statement:
ALTER TABLE "test"."alt_table" DROP COLUMN c1 [42122-195]

### What changes were proposed in this pull request?
This PR proposes to fix a bug on calling `DataType.equalsIgnoreCompatibleNullability` with mistakenly swapped parameters in `V2WriteCommand.outputResolved`. The order of parameters for `DataType.equalsIgnoreCompatibleNullability` are `from` and `to`, which says that the right order of matching variables are `inAttr` and `outAttr`.
### Why are the changes needed?
Spark throws AnalysisException due to unresolved operator in v2 write, while the operator is unresolved due to a bug that parameters to call `DataType.equalsIgnoreCompatibleNullability` in `outputResolved` have been swapped.
### Does this PR introduce _any_ user-facing change?
Yes, end users no longer suffer on unresolved operator in v2 write if they're trying to write dataframe containing non-nullable complex types against table matching complex types as nullable.

This patch is a small extension to change-request SPARK-28133, which added inverse hyperbolic functions to the SQL interpreter, but did not include those methods within the Scala `sql.functions._` API. This patch makes `acosh`, `asinh` and `atanh` functions available through the Scala API.
Unit-tests have been added to `sql/core/src/test/scala/org/apache/spark/sql/MathFunctionsSuite.scala`. Manual testing has been done via `spark-shell`, using the following recipe:
```
val df = spark.range(0, 11)
.toDF("x")
.withColumn("x", ($"x" - 5) / 2.0)
val hyps = df.withColumn("tanh", tanh($"x"))
.withColumn("sinh", sinh($"x"))
.withColumn("cosh", cosh($"x"))
val invhyps = hyps.withColumn("atanh", atanh($"tanh"))
.withColumn("asinh", asinh($"sinh"))
.withColumn("acosh", acosh($"cosh"))
invhyps.show
```
which produces the following output:
```

### What changes were proposed in this pull request?
In the PR, I propose to restrict the partial result feature only by root JSON objects. JSON datasource as well as `from_json()` will return `null` for malformed nested JSON objects.
### Why are the changes needed?
1. To not raise exception to users in the PERMISSIVE mode
2. To fix a regression and to have the same behavior as Spark 2.4.x has
3. Current implementation of partial result is supposed to work only for root (top-level) JSON objects, and not tested for bad nested complex JSON fields.
### Does this PR introduce _any_ user-facing change?
Yes. Before the changes, the code below:
```scala
val pokerhand_raw = Seq("""[{"cards": [19], "playerId": 123456}]""").toDF("events")
val event = new StructType().add("playerId", LongType).add("cards", ArrayType(new StructType().add("id", LongType).add("rank", StringType)))
val pokerhand_events = pokerhand_raw.select(from_json($"events", ArrayType(event)).as("event"))
pokerhand_events.show
```
throws the exception even in the default **PERMISSIVE** mode:
```java
java.lang.ClassCastException: java.lang.Long cannot be cast to org.apache.spark.sql.catalyst.util.ArrayData
at org.apache.spark.sql.catalyst.expressions.BaseGenericInternalRow.getArray(rows.scala:48)
at org.apache.spark.sql.catalyst.expressions.BaseGenericInternalRow.getArray$(rows.scala:48)
at org.apache.spark.sql.catalyst.expressions.GenericInternalRow.getArray(rows.scala:195)
```
After the changes:
```

```

### What changes were proposed in this pull request?
As [SPARK-13860](https://issues.apache.org/jira/browse/SPARK-13860) stated, TPCDS Query 39 returns wrong results using SparkSQL. The root cause is that when stddev_samp is applied to a single element set, with TPCDS answer, it return null; as in SparkSQL, it return Double.NaN which caused the wrong result.
Add an extra legacy config to fallback into the NaN logical, and return null by default to align with TPCDS standard.
### Why are the changes needed?
SQL correctness issue.
### Does this PR introduce any user-facing change?
Yes. See sql-migration-guide
In Spark 3.1, statistical aggregation function includes `std`, `stddev`, `stddev_samp`, `variance`, `var_samp`, `skewness`, `kurtosis`, `covar_samp`, `corr` will return `NULL` instead of `Double.NaN` when `DivideByZero` occurs during expression evaluation, for example, when `stddev_samp` applied on a single element set. In Spark version 3.0 and earlier, it will return `Double.NaN` in such case. To restore the behavior before Spark 3.1, you can set `spark.sql.legacy.statisticalAggregate` to `true`.
### How was this patch tested?
Updated DataFrameAggregateSuite/DataFrameWindowFunctionsSuite to test both default and legacy behavior.
Adjust DataFrameWindowFunctionsSuite/SQLQueryTestSuite and some R case to update to the default return null behavior.

### What changes were proposed in this pull request?
In SPARK-24994 we implemented unwrapping cast for **integral types**. This extends it to support **numeric types** such as float/double/decimal, so that filters involving these types can be better pushed down to data sources.
Unlike the cases of integral types, conversions between numeric types can result to rounding up or downs. Consider the following case:
```sql
cast(e as double) < 1.9
```
assume type of `e` is short, since 1.9 is not representable in the type, the casting will either truncate or round. Now suppose the literal is truncated, we cannot convert the expression to:
```sql
e < cast(1.9 as short)
```
as in the previous implementation, since if `e` is 1, the original expression evaluates to true, but converted expression will evaluate to false.
To resolve the above, this PR first finds out whether casting from the wider type to the narrower type will result to truncate or round, by comparing a _roundtrip value_ derived from **converting the literal first to the narrower type, and then to the wider type**, versus the original literal value. For instance, in the above, we'll first obtain a roundtrip value via the conversion (double) 1.9 -> (short) 1 -> (double) 1.0, and then compare it against 1.9.
<img width="1153" alt="Screen Shot 2020-09-28 at 3 30 27 PM" src="https://user-images.githubusercontent.com/506679/94492719-bd29e780-019f-11eb-9111-71d6e3d157f7.png">
Now in the case of truncate, we'd convert the original expression to:
```sql
e <= cast(1.9 as short)
```
instead, so that the conversion also is valid when `e` is 1.
For more details, please check [this blog post](https://prestosql.io/blog/2019/05/21/optimizing-the-casts-away.html) by Presto which offers a very good explanation on how it works.
### Why are the changes needed?
For queries such as:
```sql
SELECT * FROM tbl WHERE short_col < 100.5
```
The predicate `short_col < 100.5` can't be pushed down to data sources because it involves casts. This eliminates the cast so these queries can run more efficiently.

### What changes were proposed in this pull request?
With following scenario when AQE is on, SQLMetrics could be incorrect.
1. Stage A and B are created, and UI updated thru event onAdaptiveExecutionUpdate.
2. Stage A and B are running. Subquery in stage A keep updating metrics thru event onAdaptiveSQLMetricUpdate.
3. Stage B completes, while stage A's subquery is still running, updating metrics.
4. Completion of stage B triggers new stage creation and UI update thru event onAdaptiveExecutionUpdate again (just like step 1).
So decided to make a trade off of keeping more duplicate SQLMetrics without deleting them when AQE with newPlan updated.

### What changes were proposed in this pull request?
This PR proposes to add `DataStreamWriter.table` to specify the output "table" to write from the streaming query.
### Why are the changes needed?
For now, there's no way to write to the table (especially catalog table) even the table is capable to handle streaming write, so even with Spark 3, writing to the catalog table via SS should go through the `DataStreamWriter.format(provider)` and wish the provider can handle it as same as we do with catalog table.
With the new API, we can directly point to the catalog table which supports streaming write. Some of usages are covered with tests - simply saying, end users can do the following:
```scala
// assuming `testcat` is a custom catalog, and `ns` is a namespace in the catalog
spark.sql("CREATE TABLE testcat.ns.table1 (id bigint, data string) USING foo")
val query = inputDF
.writeStream
.table("testcat.ns.table1")
.option(...)
.start()
```
### Does this PR introduce _any_ user-facing change?
Yes, as this adds a new public API in DataStreamWriter. This doesn't bring backward incompatible change.
### How was this patch tested?
New unit tests.

### What changes were proposed in this pull request?
This is a kind of a followup of SPARK-32646. New JIRA was filed to control the fixed versions properly.
When you use `map`, it might be lazily evaluated and not executed. To avoid this, we should better use `foreach`. See also SPARK-16694. Current codes look not causing any bug for now but it should be best to fix to avoid potential issues.

### What changes were proposed in this pull request?
1. Add new method to the `JdbcDialect` class - `classifyException()`. It converts dialect specific exception to Spark's `AnalysisException` or its sub-classes.

3. Add `H2Dialect`
### Why are the changes needed?
Currently JDBC v2 Table Catalog implementation throws dialect specific exception and ignores exceptions defined in the `TableCatalog` interface. This PR adds new method for converting dialect specific exception, and assumes that follow up PRs will implement `classifyException()`.

## What changes were proposed in this pull request?
Adds a SQL function `raise_error` which underlies the refactored `assert_true` function. `assert_true` now also (optionally) accepts a custom error message field.
`raise_error` is exposed in SQL, Python, Scala, and R.
`assert_true` was previously only exposed in SQL; it is now also exposed in Python, Scala, and R.
### Why are the changes needed?
Improves usability of `assert_true` by clarifying error messaging, and adds the useful helper function `raise_error`.
### Does this PR introduce _any_ user-facing change?
Yes:
- Adds `raise_error` function to the SQL, Python, Scala, and R APIs.
- Adds `assert_true` function to the SQL, Python and R APIs.
### How was this patch tested?
Adds unit tests in SQL, Python, Scala, and R for `assert_true` and `raise_error`.

### What changes were proposed in this pull request?
This PR proposes to migrate `DESCRIBE tbl colname` to use `UnresolvedTableOrView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
### Why are the changes needed?
The current behavior is not consistent between v1 and v2 commands when resolving a temp view.
In v2, the `t` in the following example is resolved to a table:
```scala
sql("CREATE TABLE testcat.ns.t (id bigint) USING foo")
sql("CREATE TEMPORARY VIEW t AS SELECT 2 as i")
sql("USE testcat.ns")
sql("DESCRIBE t i") // 't' is resolved to testcat.ns.t
Describing columns is not supported for v2 tables.;
org.apache.spark.sql.AnalysisException: Describing columns is not supported for v2 tables.;
```
whereas in v1, the `t` is resolved to a temp view:
```scala
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint) USING csv")
sql("CREATE TEMPORARY VIEW t AS SELECT 2 as i")
sql("USE spark_catalog.test")
sql("DESCRIBE t i").show // 't' is resolved to a temp view

When we create a UDAF function use class extended `UserDefinedAggregeteFunction`, when we call the function, in support hive mode, in HiveSessionCatalog, it will call super.makeFunctionExpression,
but it will catch error such as the function need 2 parameter and we only give 1, throw exception only show
```
No handler for UDF/UDAF/UDTF xxxxxxxx
```
This is confused for develop , we should show error thrown by super method too,
For this pr's UT :
Before change, throw Exception like
```
No handler for UDF/UDAF/UDTF 'org.apache.spark.sql.hive.execution.LongProductSum'; line 1 pos 7
```

### What changes were proposed in this pull request?
1. Refactored `WithFields` Expression to make it more extensible (now `UpdateFields`).
2. Added a new `dropFields` method to the `Column` class. This method should allow users to drop a `StructField` in a `StructType` column (with similar semantics to the `drop` method on `Dataset`).
### Why are the changes needed?
Often Spark users have to work with deeply nested data e.g. to fix a data quality issue with an existing `StructField`. To do this with the existing Spark APIs, users have to rebuild the entire struct column.
For example, let's say you have the following deeply nested data structure which has a data quality issue (`5` is missing):
```
import org.apache.spark.sql._
import org.apache.spark.sql.functions._
import org.apache.spark.sql.types._
val data = spark.createDataFrame(sc.parallelize(
Seq(Row(Row(Row(1, 2, 3), Row(Row(4, null, 6), Row(7, 8, 9), Row(10, 11, 12)), Row(13, 14, 15))))),
StructType(Seq(
StructField("a", StructType(Seq(
StructField("a", StructType(Seq(
StructField("a", IntegerType),
StructField("b", IntegerType),
StructField("c", IntegerType)))),
StructField("b", StructType(Seq(
StructField("a", StructType(Seq(
StructField("a", IntegerType),
StructField("b", IntegerType),
StructField("c", IntegerType)))),
StructField("b", StructType(Seq(
StructField("a", IntegerType),
StructField("b", IntegerType),
StructField("c", IntegerType)))),
StructField("c", StructType(Seq(
StructField("a", IntegerType),
StructField("b", IntegerType),
StructField("c", IntegerType))))
))),
StructField("c", StructType(Seq(
StructField("a", IntegerType),
StructField("b", IntegerType),
StructField("c", IntegerType))))
)))))).cache
data.show(false)
+---------------------------------+
|a |
+---------------------------------+
|[[1, 2, 3], [[4,, 6], [7, 8, 9]]]|
+---------------------------------+
```
Currently, to drop the missing value users would have to do something like this:
```
val result = data.withColumn("a",
struct(
$"a.a",
struct(
struct(
$"a.b.a.a",
$"a.b.a.c"
).as("a"),
$"a.b.b",
$"a.b.c"
).as("b"),
$"a.c"
))
result.show(false)
+---------------------------------------------------------------+
|a |
+---------------------------------------------------------------+
|[[1, 2, 3], [[4, 6], [7, 8, 9], [10, 11, 12]], [13, 14, 15]]|
+---------------------------------------------------------------+
```
As you can see above, with the existing methods users must call the `struct` function and list all fields, including fields they don't want to change. This is not ideal as:
>this leads to complex, fragile code that cannot survive schema evolution.
[SPARK-16483](https://issues.apache.org/jira/browse/SPARK-16483)
In contrast, with the method added in this PR, a user could simply do something like this to get the same result:
```
val result = data.withColumn("a", 'a.dropFields("b.a.b"))
result.show(false)
+---------------------------------------------------------------+
|a |
+---------------------------------------------------------------+
|[[1, 2, 3], [[4, 6], [7, 8, 9], [10, 11, 12]], [13, 14, 15]]|
+---------------------------------------------------------------+
```
This is the second of maybe 3 methods that could be added to the `Column` class to make it easier to manipulate nested data.
Other methods under discussion in [SPARK-22231](https://issues.apache.org/jira/browse/SPARK-22231) include `withFieldRenamed`.
However, this should be added in a separate PR.
### Does this PR introduce _any_ user-facing change?
The documentation for `Column.withField` method has changed to include an additional note about how to write optimized queries when adding multiple nested Column directly.
### How was this patch tested?
New unit tests were added. Jenkins must pass them.

### What changes were proposed in this pull request?
This PR intends to fix corner-case bugs in the `QueryPlan#transformUpWithNewOutput` that is used to propagate updated `ExprId`s in a bottom-up way. Let's say we have a rule to simply assign new `ExprId`s in a projection list like this;
```
case class TestRule extends Rule[LogicalPlan] {
override def apply(plan: LogicalPlan): LogicalPlan = plan.transformUpWithNewOutput {
case p Project(projList, _) =>
val newPlan = p.copy(projectList = projList.map { _.transform {
// Assigns a new `ExprId` for references
case a: AttributeReference => Alias(a, a.name)()
}}.asInstanceOf[Seq[NamedExpression]])
val attrMapping = p.output.zip(newPlan.output)
newPlan -> attrMapping
}
}
```
Then, this rule is applied into a plan below;
```
(3) Project [a#5, b#6]
+- (2) Project [a#5, b#6]
+- (1) Project [a#5, b#6]
+- LocalRelation <empty>, [a#5, b#6]
```
In the first transformation, the rule assigns new `ExprId`s in `(1) Project` (e.g., a#5 AS a#7, b#6 AS b#8). In the second transformation, the rule corrects the input references of `(2) Project` first by using attribute mapping given from `(1) Project` (a#5->a#7 and b#6->b#8) and then assigns new `ExprId`s (e.g., a#7 AS a#9, b#8 AS b#10). But, in the third transformation, the rule fails because it tries to correct the references of `(3) Project` by using incorrect attribute mapping (a#7->a#9 and b#8->b#10) even though the correct one is a#5->a#9 and b#6->b#10. To fix this issue, this PR modified the code to update the attribute mapping entries that are obsoleted by generated entries in a given rule.

<hive.version>1.2.1.spark2</hive.version>
```
For the forked Hive 1.2.1.spark2 users, Apache Spark 2.4(LTS) and 3.0 (~ 2021.12) will provide it.
### Why are the changes needed?
- First, Apache Spark community should not use the unofficial forked release of another Apache project.
- Second, Apache Hive 1.2.1 was released at 2015-06-26 and the forked Hive `1.2.1.spark2` exposed many unfixable bugs in Apache because the forked `1.2.1.spark2` is not maintained at all. Apache Hive 2.3.0 was released at 2017-07-19 and it has been used with less number of bugs compared with `1.2.1.spark2`. Many bugs still exist in `hive-1.2` profile and new Apache Spark unit tests are added with `HiveUtils.isHive23` condition so far.
### Does this PR introduce _any_ user-facing change?
No. This is a dev-only change. PRBuilder will not accept `[test-hive1.2]` on master and `branch-3.1`.

### What changes were proposed in this pull request?
This PR combines the current plan and the initial plan in the AQE query plan string when the two plans are the same. It also removes the `== Current Plan ==` and `== Initial Plan ==` headers:
Before
```scala
AdaptiveSparkPlan isFinalPlan=false
+- == Current Plan ==
SortMergeJoin [key#13], [a#23], Inner
:- Sort [key#13 ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(key#13, 5), true, [id=#94]
...
+- == Initial Plan ==
SortMergeJoin [key#13], [a#23], Inner
:- Sort [key#13 ASC NULLS FIRST], false, 0
: +- Exchange hashpartitioning(key#13, 5), true, [id=#94]
...
```
After
```scala
AdaptiveSparkPlan isFinalPlan=false

### What changes were proposed in this pull request?
At the moment only the baked in JDBC connection providers can be used but there is a need to support additional databases and use-cases. In this PR I'm proposing a new developer API name `JdbcConnectionProvider`. To show how an external JDBC connection provider can be implemented I've created an example [here](https://github.com/gaborgsomogyi/spark-jdbc-connection-provider).
The PR contains the following changes:
* Added connection provider developer API
* Made JDBC connection providers constructor to noarg => needed to load them w/ service loader
* Connection providers are now loaded w/ service loader
* Added tests to load providers independently
* Moved `SecurityConfigurationLock` into a central place because other areas will change global JVM security config
### Why are the changes needed?
No custom authentication possibility.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
* Existing + additional unit tests
* Docker integration tests
* Tested manually the newly created external JDBC connection provider

### What changes were proposed in this pull request?
This PR is to add support to decide bucketed table scan dynamically based on actual query plan. Currently bucketing is enabled by default (`spark.sql.sources.bucketing.enabled`=true), so for all bucketed tables in the query plan, we will use bucket table scan (all input files per the bucket will be read by same task). This has the drawback that if the bucket table scan is not benefitting at all (no join/groupby/etc in the query), we don't need to use bucket table scan as it would restrict the # of tasks to be # of buckets and might hurt parallelism.
The feature is to add a physical plan rule right after `EnsureRequirements`:
The rule goes through plan nodes. For all operators which has "interesting partition" (i.e., require `ClusteredDistribution` or `HashClusteredDistribution`), check if the sub-plan for operator has `Exchange` and bucketed table scan (and only allow certain operators in plan (i.e. `Scan/Filter/Project/Sort/PartialAgg/etc`.), see details in `DisableUnnecessaryBucketedScan.disableBucketWithInterestingPartition`). If yes, disable the bucketed table scan in the sub-plan. In addition, disabling bucketed table scan if there's operator with interesting partition along the sub-plan.
Why the algorithm works is that if there's a shuffle between the bucketed table scan and operator with interesting partition, then bucketed table scan partitioning will be destroyed by the shuffle operator in the middle, and we don't need bucketed table scan for sure.
The idea of "interesting partition" is inspired from "interesting order" in "Access Path Selection in a Relational Database Management System"(http://www.inf.ed.ac.uk/teaching/courses/adbs/AccessPath.pdf), after discussion with cloud-fan .
### Why are the changes needed?
To avoid unnecessary bucketed scan in the query, and this is prerequisite for https://github.com/apache/spark/pull/29625 (decide bucketed sorted scan dynamically will be added later in that PR).
### Does this PR introduce _any_ user-facing change?
A new config `spark.sql.sources.bucketing.autoBucketedScan.enabled` is introduced which set to false by default (the rule is disabled by default as it can regress cached bucketed table query, see discussion in https://github.com/apache/spark/pull/29804#issuecomment-701151447). User can opt-in/opt-out by enabling/disabling the config, as we found in prod, some users rely on assumption of # of tasks == # of buckets when reading bucket table to precisely control # of tasks. This is a bad assumption but it does happen on our side, so leave a config here to allow them opt-out for the feature.
### How was this patch tested?
Added unit tests in `DisableUnnecessaryBucketedScanSuite.scala`

### What changes were proposed in this pull request?
Add code in `ScalaReflection` to support scala enumeration and make enumeration type as string type in Spark.
### Why are the changes needed?
We support java enum but failed with scala enum, it's better to keep the same behavior.
Here is a example.
```
package test
object TestEnum extends Enumeration {
type TestEnum = Value
val E1, E2, E3 = Value
}
import TestEnum._
case class TestClass(i: Int, e: TestEnum) {
}
import test._
Seq(TestClass(1, TestEnum.E1)).toDS
```

After `SPARK-32851` set `CODEGEN_FACTORY_MODE` to `CODEGEN_ONLY` of `sparkConf` in `SharedSparkSessionBase` to construction `SparkSession` in test, the test suite `SPARK-32459: UDF should not fail on WrappedArray` in s.sql.UDFSuite exposed a codegen fallback issue in Scala 2.13 as follow:
```

Manually tested on JDK8u and JDK11u and observed expected behavior:
- JDK8u: the test case triggers the "Malformed class name" issue and the fix works;
- JDK11u: the test case does not trigger the "Malformed class name" issue, and the test case is safely skipped.

### Why are the changes needed?
Users can directly use this API to get a Streaming DataFrame on a table. Below is a simple example:
Application 1 for initializing and starting the streaming job:

val path = "/home/yuanjian.li/runtime/to_be_deleted"
val tblName = "my_table"
// Write some data to `my_table`
spark.range(3).write.format("parquet").option("path", path).saveAsTable(tblName)
// Read the table as a streaming source, write result to destination directory
val table = spark.readStream.table(tblName)
table.writeStream.format("parquet").option("checkpointLocation", "/home/yuanjian.li/runtime/to_be_deleted_ck").start("/home/yuanjian.li/runtime/to_be_deleted_2")
```
Application 2 for appending new data:
```
// Append new data into the path
spark.range(5).write.format("parquet").option("path", "/home/yuanjian.li/runtime/to_be_deleted").mode("append").save()
```
Check result:
```
// The desitination directory should contains all written data
spark.read.parquet("/home/yuanjian.li/runtime/to_be_deleted_2").show()

### What changes were proposed in this pull request?
This PR proposes to migrate `REFRESH TABLE` to use `UnresolvedTableOrView` to resolve the table/view identifier. This allows consistent resolution rules (temp view first, etc.) to be applied for both v1/v2 commands. More info about the consistent resolution rule proposal can be found in [JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
### Why are the changes needed?
The current behavior is not consistent between v1 and v2 commands when resolving a temp view.
In v2, the `t` in the following example is resolved to a table:
```scala
sql("CREATE TABLE testcat.ns.t (id bigint) USING foo")
sql("CREATE TEMPORARY VIEW t AS SELECT 2")
sql("USE testcat.ns")
sql("REFRESH TABLE t") // 't' is resolved to testcat.ns.t
```
whereas in v1, the `t` is resolved to a temp view:
```scala
sql("CREATE DATABASE test")
sql("CREATE TABLE spark_catalog.test.t (id bigint) USING csv")
sql("CREATE TEMPORARY VIEW t AS SELECT 2")
sql("USE spark_catalog.test")
sql("REFRESH TABLE t") // 't' is resolved to a temp view
```
### Does this PR introduce _any_ user-facing change?
After this PR, `REFRESH TABLE t` is resolved to a temp view `t` instead of `testcat.ns.t`.
### How was this patch tested?

This moves and refactors the parallel listing utilities from `InMemoryFileIndex` to Spark core so it can be reused by modules beside SQL. Along the process this also did some cleanups/refactorings:
- Created a `HadoopFSUtils` class under core
- Moved `InMemoryFileIndex.bulkListLeafFiles` into `HadoopFSUtils.parallelListLeafFiles`. It now depends on a `SparkContext` instead of `SparkSession` in SQL. Also added a few parameters which used to be read from `SparkSession.conf`: `ignoreMissingFiles`, `ignoreLocality`, `parallelismThreshold`, `parallelismMax ` and `filterFun` (for additional filtering support but we may be able to merge this with `filter` parameter in future).
- Moved `InMemoryFileIndex.listLeafFiles` into `HadoopFSUtils.listLeafFiles` with similar changes above.
### Why are the changes needed?

Currently the locality-aware parallel listing mechanism only applies to `InMemoryFileIndex`. By moving this to core, we can potentially reuse the same mechanism for other code paths as well.

### What changes were proposed in this pull request?
Remove unnecessary code.
### Why are the changes needed?
General housekeeping. Might be a slight performance improvement, especially on big-endian systems.
There is no need for separate code paths for big- and little-endian
platforms in putDoubles and putFloats anymore (since PR #24861). On
all platforms values are encoded in native byte order and can just
be copied directly.
### Does this PR introduce _any_ user-facing change?
No.

MurmurHash3 and xxHash64 interpret sequences of bytes as integers
encoded in little-endian byte order. This requires a byte reversal
on big endian platforms.
I've left the hashInt and hashLong functions as-is for now. My
interpretation of these functions is that they perform the hash on
the integer value as if it were serialized in little-endian byte
order. Therefore no byte reversal is necessary.
### What changes were proposed in this pull request?
Modify hash functions to produce correct results on big-endian platforms.
### Why are the changes needed?
Hash functions produce incorrect results on big-endian platforms which, amongst other potential issues, causes test failures.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Existing tests run on the IBM Z (s390x) platform which uses a big-endian byte order.

### What changes were proposed in this pull request?
This PR addresses two issues related to the `Relation: view text` test in `DataSourceV2SQLSuite`.
1. The test has the following block:
```scala
withView("view1") { v1: String =>
sql(...)
}
```
Since `withView`'s signature is `withView(v: String*)(f: => Unit): Unit`, the `f` that will be executed is ` v1: String => sql(..)`, which is just defining the anonymous function, and _not_ executing it.
2. Once the test is fixed to run, it actually fails. The reason is that the v2 session catalog implementation used in tests does not correctly handle `V1Table` for views in `loadTable`. And this results in views resolved to `ResolvedTable` instead of `ResolvedView`, causing the test failure: f1dc479d39/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/analysis/Analyzer.scala (L1007-L1011)

In the PR, I propose to replace current examples for `percentile_approx()` with **only one** input value by example **with multiple values** in the input column.

### What changes were proposed in this pull request?
In current mode, when explain a SQL plan with HiveTableRelation, it will show so many info about HiveTableRelation's prunedPartition, this make plan hard to read, this pr make this information simpler.
Before:
For UT
```
test("Make HiveTableScanExec message simple") {
withSQLConf("hive.exec.dynamic.partition.mode" -> "nonstrict") {
withTable("df") {
spark.range(30)
.select(col("id"), col("id").as("k"))
.write
.partitionBy("k")
.format("hive")
.mode("overwrite")
.saveAsTable("df")
val df = sql("SELECT df.id, df.k FROM df WHERE df.k < 2")
df.explain(true)
}
}
}
```
After this pr will show
```
== Parsed Logical Plan ==
'Project ['df.id, 'df.k]
+- 'Filter ('df.k < 2)
+- 'UnresolvedRelation [df], []
== Analyzed Logical Plan ==
id: bigint, k: bigint
Project [id#11L, k#12L]
+- Filter (k#12L < cast(2 as bigint))
+- SubqueryAlias spark_catalog.default.df
+- HiveTableRelation [`default`.`df`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, Data Cols: [id#11L], Partition Cols: [k#12L]]
== Optimized Logical Plan ==
Filter (isnotnull(k#12L) AND (k#12L < 2))
+- HiveTableRelation [`default`.`df`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, Data Cols: [id#11L], Partition Cols: [k#12L], Pruned Partitions: [(k=0), (k=1)]]
== Physical Plan ==
Scan hive default.df [id#11L, k#12L], HiveTableRelation [`default`.`df`, org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe, Data Cols: [id#11L], Partition Cols: [k#12L], Pruned Partitions: [(k=0), (k=1)]], [isnotnull(k#12L), (k#12L < 2)]
```
In my pr, I will construct `HiveTableRelation`'s `simpleString` method to avoid show too much unnecessary info in explain plan. compared to what we had before，I decrease the detail metadata of each partition and only retain the partSpec to show each partition was pruned. Since for detail information, we always don't see this in Plan but to use DESC EXTENDED statement.

### What changes were proposed in this pull request?
After https://github.com/apache/spark/pull/29660 and https://github.com/apache/spark/pull/29689 there are 13 remaining failed cases of sql core module with Scala 2.13.
The reason for the remaining failed cases is the optimization result of `CostBasedJoinReorder` maybe different with same input in Scala 2.12 and Scala 2.13 if there are more than one same cost candidate plans.
In this pr give a way to make the optimization result deterministic as much as possible to pass all remaining failed cases of `sql/core` module in Scala 2.13, the main change of this pr as follow:
- Change to use `LinkedHashMap` instead of `Map` to store `foundPlans` in `JoinReorderDP.search` method to ensure same iteration order with same insert order because iteration order of `Map` behave differently under Scala 2.12 and 2.13
- Fixed `StarJoinCostBasedReorderSuite` affected by the above change
- Regenerate golden files affected by the above change.
### Why are the changes needed?
We need to support a Scala 2.13 build.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
- Scala 2.12: Pass the Jenkins or GitHub Action
- Scala 2.13: All tests passed.
Do the following:
```
dev/change-scala-version.sh 2.13
mvn clean install -DskipTests -pl sql/core -Pscala-2.13 -am
mvn test -pl sql/core -Pscala-2.13
```

1. Change the target error calculation according to the paper [Space-Efficient Online Computation of Quantile Summaries](http://infolab.stanford.edu/~datar/courses/cs361a/papers/quantiles.pdf). It says that the error `e = max(gi, deltai)/2` (see the page 59). Also this has clear explanation [ε-approximate quantiles](http://www.mathcs.emory.edu/~cheung/Courses/584/Syllabus/08-Quantile/Greenwald.html#proofprop1).
2. Added a test to check different accuracies.

### What changes were proposed in this pull request?
This PR rewrites `FoldablePropagation` rule to replace attribute references in a node with foldables coming only from the node's children.
Before this PR in the case of this example (with setting`spark.sql.optimizer.excludedRules=org.apache.spark.sql.catalyst.optimizer.ConvertToLocalRelation`):
```scala
val a = Seq("1").toDF("col1").withColumn("col2", lit("1"))
val b = Seq("2").toDF("col1").withColumn("col2", lit("2"))
val aub = a.union(b)
val c = aub.filter($"col1" === "2").cache()
val d = Seq("2").toDF( "col4")
val r = d.join(aub, $"col2" === $"col4").select("col4")
val l = c.select("col2")
val df = l.join(r, $"col2" === $"col4", "LeftOuter")
df.show()
```
foldable propagation happens incorrectly:
```
Join LeftOuter, (col2#6 = col4#34) Join LeftOuter, (col2#6 = col4#34)
!:- Project [col2#6] :- Project [1 AS col2#6]
: +- InMemoryRelation [col1#4, col2#6], StorageLevel(disk, memory, deserialized, 1 replicas) : +- InMemoryRelation [col1#4, col2#6], StorageLevel(disk, memory, deserialized, 1 replicas)
: +- Union : +- Union
: :- *(1) Project [value#1 AS col1#4, 1 AS col2#6] : :- *(1) Project [value#1 AS col1#4, 1 AS col2#6]
: : +- *(1) Filter (isnotnull(value#1) AND (value#1 = 2)) : : +- *(1) Filter (isnotnull(value#1) AND (value#1 = 2))
: : +- *(1) LocalTableScan [value#1] : : +- *(1) LocalTableScan [value#1]
: +- *(2) Project [value#10 AS col1#13, 2 AS col2#15] : +- *(2) Project [value#10 AS col1#13, 2 AS col2#15]
: +- *(2) Filter (isnotnull(value#10) AND (value#10 = 2)) : +- *(2) Filter (isnotnull(value#10) AND (value#10 = 2))
: +- *(2) LocalTableScan [value#10] : +- *(2) LocalTableScan [value#10]
+- Project [col4#34] +- Project [col4#34]
+- Join Inner, (col2#6 = col4#34) +- Join Inner, (col2#6 = col4#34)
:- Project [value#31 AS col4#34] :- Project [value#31 AS col4#34]
: +- LocalRelation [value#31] : +- LocalRelation [value#31]
+- Project [col2#6] +- Project [col2#6]
+- Union false, false +- Union false, false
:- Project [1 AS col2#6] :- Project [1 AS col2#6]
: +- LocalRelation [value#1] : +- LocalRelation [value#1]
+- Project [2 AS col2#15] +- Project [2 AS col2#15]
+- LocalRelation [value#10] +- LocalRelation [value#10]
```
and so the result is wrong:
```
+----+----+
|col2|col4|
+----+----+
| 1|null|
+----+----+
```
After this PR foldable propagation will not happen incorrectly and the result is correct:
```
+----+----+
|col2|col4|
+----+----+
| 2| 2|
+----+----+

This pr fix failed and aborted cases in sql hive-thriftserver module in Scala 2.13, the main change of this pr as follow:
- Use `s.c.Seq` instead of `Seq` in `HiveResult` because the input type maybe `mutable.ArraySeq`, but `Seq` represent `immutable.Seq` in Scala 2.13.
- Reset classLoader after `HiveMetastoreLazyInitializationSuite` completed because context class loader is `NonClosableMutableURLClassLoader` in `HiveMetastoreLazyInitializationSuite` running process, and it propagate to `HiveThriftServer2ListenerSuite` trigger following problems in Scala 2.13:
```
HiveThriftServer2ListenerSuite:

### What changes were proposed in this pull request?
This is a follow-up on #29565, and addresses a few issues in the last PR:
- style issue pointed by [this comment](https://github.com/apache/spark/pull/29565#discussion_r487646749)
- skip optimization when `fromExp` is foldable (by [this comment](https://github.com/apache/spark/pull/29565#discussion_r487646973)) as there could be more efficient rule to apply for this case.
- pass timezone info to the generated cast on the literal value
- a bunch of cleanups and test improvements
Originally I plan to handle this when implementing [SPARK-32858](https://issues.apache.org/jira/browse/SPARK-32858) but now think it's better to isolate these changes from that.
### Why are the changes needed?
To fix a few left over issues in the above PR.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?

This patch proposes to make GeneratePredicate eliminate common sub-expressions.
### Why are the changes needed?
Both GenerateMutableProjection and GenerateUnsafeProjection, such codegen objects can eliminate common sub-expressions. But GeneratePredicate currently doesn't do it.
We encounter a customer issue that a Filter pushed down through a Project causes performance issue, compared with not pushed down case. The issue is one expression used in Filter predicates are run many times. Due to the complex schema, the query nodes are not wholestage codegen, so it runs Filter.doExecute and then call GeneratePredicate. The common expression was run many time and became performance bottleneck. GeneratePredicate should be able to eliminate common sub-expressions for such case.

### What changes were proposed in this pull request?
Credits to tdas who reported and described the fix to [SPARK-26425](https://issues.apache.org/jira/browse/SPARK-26425). I just followed the description of the issue.
This patch adds more checks on commit log as well as file streaming source so that multiple concurrent runs of streaming query don't mess up the status of query/checkpoint. This patch addresses two different spots which are having a bit different issues:
1. FileStreamSource.fetchMaxOffset()
In structured streaming, we don't allow multiple streaming queries to run with same checkpoint (including concurrent runs of same query), so query should fail if it fails to write the metadata of specific batch ID due to same batch ID being written by others.
2. commit log
As described in JIRA issue, assertion is already applied to the `offsetLog` for the same reason.
8167714cab/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/MicroBatchExecution.scala (L394-L402)
This patch applied the same for commit log.
### Why are the changes needed?
This prevents the inconsistent behavior on streaming query and lets query fail instead.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
N/A, as the change is simple and obvious, and it's really hard to artificially reproduce the issue.

### What changes were proposed in this pull request?
This PR fixes a conflict between `RewriteDistinctAggregates` and `DecimalAggregates`.
In some cases, `DecimalAggregates` will wrap the decimal column to `UnscaledValue` using
different rules for different aggregates.
This means, same distinct column with different aggregates will change to different distinct columns
after `DecimalAggregates`. For example:
`avg(distinct decimal_col), sum(distinct decimal_col)` may change to
`avg(distinct UnscaledValue(decimal_col)), sum(distinct decimal_col)`
We assume after `RewriteDistinctAggregates`, there will be at most one distinct column in aggregates,
but `DecimalAggregates` breaks this assumption. To fix this, we have to switch the order of these two
rules.

### What changes were proposed in this pull request?
This PR updates the `RemoveRedundantProjects` rule to make `GenerateExec` require column ordering.
### Why are the changes needed?
`GenerateExec` was originally considered as a node that does not require column ordering. However, `GenerateExec` binds its input rows directly with its `requiredChildOutput` without using the child's output schema.
In `doExecute()`:
```scala
val proj = UnsafeProjection.create(output, output)
```
In `doConsume()`:
```scala
val values = if (requiredChildOutput.nonEmpty) {
input
} else {
Seq.empty
}
```
In this case, changing input column ordering will result in `GenerateExec` binding the wrong schema to the input columns. For example, if we do not require child columns to be ordered, the `requiredChildOutput` [a, b, c] will directly bind to the schema of the input columns [c, b, a], which is incorrect:
```
GenerateExec explode(array(a, b, c)), [a, b, c], false, [d]
HashAggregate(keys=[a, b, c], functions=[], output=[c, b, a])
...
```

### What changes were proposed in this pull request?
The `LiteralGenerator` for float and double datatypes was supposed to yield special values (NaN, +-inf) among others, but the `Gen.chooseNum` method does not yield values that are outside the defined range. The `Gen.chooseNum` for a wide range of floats and doubles does not yield values in the "everyday" range as stated in https://github.com/typelevel/scalacheck/issues/113 .
There is an similar class `RandomDataGenerator` that is used in some other tests. Added `-0.0` and `-0.0f` as special values to there too.
These changes revealed an inconsistency with the equality check between `-0.0` and `0.0`.
### Why are the changes needed?

Add a new config `spark.sql.maxMetadataStringLength`. This config aims to limit metadata value length, e.g. file location.

### What changes were proposed in this pull request?
This PR refactors the way we propagate the options from the `SparkSession.Builder` to the` SessionState`. This currently done via a mutable map inside the SparkSession. These setting settings are then applied **after** the Session. This is a bit confusing when you expect something to be set when constructing the `SessionState`. This PR passes the options as a constructor parameter to the `SessionStateBuilder` and this will set the options when the configuration is created.
### Why are the changes needed?
It makes it easier to reason about the configurations set in a SessionState than before. We recently had an incident where someone was using `SparkSessionExtensions` to create a planner rule that relied on a conf to be set. While this is in itself probably incorrect usage, it still illustrated this somewhat funky behavior.

### What changes were proposed in this pull request?
Several minor code and documentation improvement for stream-stream join. Specifically:
* Remove extending from `SparkPlan`, as extending from `BinaryExecNode` is enough.
* Return `left/right.outputPartitioning` for `Left/RightOuter` in `outputPartitioning`, as the `PartitioningCollection` wrapper is unnecessary (similar to batch joins `ShuffledHashJoinExec`, `SortMergeJoinExec`).
* Avoid per-row check for join type (https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/streaming/StreamingSymmetricHashJoinExec.scala#L486-L492), by creating the method before the loop of reading rows (`generateFilteredJoinedRow` in `storeAndJoinWithOtherSide`). Similar optimization (i.e. create auxiliary method/variable per different join type before the iterator of input rows) has been done in batch join world (`SortMergeJoinExec`, `ShuffledHashJoinExec`).
* Minor fix for comment/indentation for better readability.
### Why are the changes needed?
Minor optimization to avoid per-row unnecessary work (this probably can be optimized away by compiler, but we can do a better join to avoid it at the first place). And other comment/indentation fix to have better code readability for future developers.

### What changes were proposed in this pull request?
Currently, in cases like the following:
```sql
SELECT * FROM t WHERE age < 40
```
where `age` is of short type, Spark won't be able to simplify this and can only generate filter `cast(age, int) < 40`. This won't get pushed down to datasources and therefore is not optimized.
This PR proposes a optimizer rule to improve this when the following constraints are satisfied:
- input expression is binary comparisons when one side is a cast operation and another is a literal.
- both the cast child expression and literal are of integral type (i.e., byte, short, int or long)
When this is true, it tries to do several optimizations to either simplify the expression or move the cast to the literal side, so
result filter for the above case becomes `age < cast(40 as smallint)`. This is better since the cast can be optimized away later and the filter can be pushed down to data sources.
This PR follows a similar effort in Presto (https://prestosql.io/blog/2019/05/21/optimizing-the-casts-away.html). Here we only handles integral types but plan to extend to other types as follow-ups.
### Why are the changes needed?
As mentioned in the previous section, when cast is not optimized, it cannot be pushed down to data sources which can lead
to unnecessary IO and therefore longer job time and waste of resources. This helps to improve that.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Added unit tests for both the optimizer rule and filter pushdown on datasource level for both Orc and Parquet.

### What changes were proposed in this pull request?
This is an attempt to adapt Spark REPL to Scala 2.13.
It is based on a [scala-2.13 branch](https://github.com/smarter/spark/tree/scala-2.13) made by smarter.
I had to set Scala version to 2.13 in some places, and to adapt some other modules, before I could start working on the REPL itself. These are separate commits on the branch that probably would be fixed beforehand, and thus dropped before the merge of this PR.
I couldn't find a way to run the initialization code with existing REPL classes in Scala 2.13.2, so I [modified REPL in Scala](e9cc0dd547) to make it work. With this modification I managed to run Spark Shell, along with the units tests passing, which is good news.
The bad news is that it requires an upstream change in Scala, which must be accepted first. I'd be happy to change it if someone points a way to do it differently. If not, I'd propose a PR in Scala to introduce `ILoop.internalReplAutorunCode`.
### Why are the changes needed?
REPL in Scala changed quite a lot, so current version of Spark REPL needed to be adapted.
### Does this PR introduce _any_ user-facing change?
In the previous version of `SparkILoop`, a lot of Scala's `ILoop` code was [overridden and duplicated](2bc7b75537) to make the welcome message a bit more pleasant. In this PR, the message is in a bit different order, but it's still acceptable IMHO.

It seems that currently the welcoming message is still an improvement from [the original ticket](https://issues.apache.org/jira/browse/SPARK-24785), albeit in a different order. As a bonus, some fragile code duplication was removed.

### What changes were proposed in this pull request?
This PR intends to set `CODEGEN_ONLY` at `CODEGEN_FACTORY_MODE` in test spark context so that tests can fail if errors happen when generating expr code.
### Why are the changes needed?
I noticed that the code generation of `SafeProjection` failed in the existing test (https://issues.apache.org/jira/browse/SPARK-32828) but it passed because `FALLBACK` was set at `CODEGEN_FACTORY_MODE` (by default) in `SharedSparkSession`.

### What changes were proposed in this pull request?
This PR aims to add `sinkParameter` to check sink options robustly and independently in DataStreamReaderWriterSuite
### Why are the changes needed?
`LastOptions.parameters` is designed to catch three cases: `sourceSchema`, `createSource`, `createSink`. However, `StreamQuery.stop` invokes `queryExecutionThread.join`, `runStream`, `createSource` immediately and reset the stored options by `createSink`.
To catch `createSink` options, currently, the test suite is trying a workaround pattern. However, we observed a flakiness in this pattern sometimes. If we split `createSink` option separately, we don't need this workaround and can eliminate this flakiness.
```scala
val query = df.writeStream.
...
.start()
assert(LastOptions.paramters(..))
query.stop()
```

### What changes were proposed in this pull request?
This is a followup of https://github.com/apache/spark/pull/29328
In https://github.com/apache/spark/pull/29328 , we forbid the use case that path option and path parameter are both specified. However, it breaks some use cases:
```
val dfr = spark.read.format(...).option(...)
dfr.load(path1).xxx
dfr.load(path2).xxx
```
The reason is that: `load` has side effects. It will set path option to the `DataFrameReader` instance. The next time you call `load`, Spark will fail because both path option and path parameter are specified.
This PR removes the side effect of `save`/`load`/`start` to not set the path option.

### What changes were proposed in this pull request?
This patch proposes to update the doc (both SS guide doc and Dataset dropDuplicates method doc) to leave a note to check on using SQL statements with streaming Dataset.
Once end users create a temp view based on streaming Dataset, they won't bother with thinking about "streaming" and do whatever they do with batch query. In many cases it works, but not just smoothly for the case when streaming aggregation is involved. They still need to concern about maintaining state store.
### Why are the changes needed?
Although SPARK-32456 fixed the weird error message, as a side effect some operations are enabled on streaming workload via SQL statement, which is error-prone if end users don't indicate what they're doing.

### What changes were proposed in this pull request?
This PR renames `SupportsStreamingUpdate` to `SupportsStreamingUpdateAsAppend` as the new interface name represents the actual behavior clearer. This PR also removes the `update()` method (so the interface is more likely a marker), as the implementations of `SupportsStreamingUpdateAsAppend` should support append mode by default, hence no need to trigger some flag on it.
### Why are the changes needed?
SupportsStreamingUpdate was intended to revive the functionality of Streaming update output mode for internal data sources, but despite the name, that interface isn't really used to do actual update on sink; all sinks are implementing this interface to do append, so strictly saying, it's just to support update as append. Renaming the interface would make it clear.
### Does this PR introduce _any_ user-facing change?
No, as the class is only for internal data sources.

### What changes were proposed in this pull request?
This patch proposes to check `ignoreNullability` parameter recursively in `equalsStructurally` method.
### Why are the changes needed?
`equalsStructurally` is used to check type equality. We can optionally ask to ignore nullability check. But the parameter `ignoreNullability` is not passed recursively down to nested types. So it produces weird error like:
```
data type mismatch: argument 3 requires array<array<string>> type, however ... is of array<array<string>> type.
```
when running the query `select aggregate(split('abcdefgh',''), array(array('')), (acc, x) -> array(array( x ) ) )`.

### What changes were proposed in this pull request?
This PR is a follow up to https://github.com/apache/spark/pull/29543#discussion_r485409606, which correctly points out that the check for the empty string is not necessary.
### Why are the changes needed?
The unnecessary check actually could cause more confusion.
For example,
```scala
scala> Seq(1).toDF.write.option("path", "/tmp/path1").parquet("")
java.lang.IllegalArgumentException: Can not create a Path from an empty string
at org.apache.hadoop.fs.Path.checkPathArg(Path.java:168)
```
even when `path` option is available. This PR addresses to fix this confusion.
### Does this PR introduce _any_ user-facing change?
Yes, now the above example prints the consistent exception message whether the path parameter value is empty or not.
```scala
scala> Seq(1).toDF.write.option("path", "/tmp/path1").parquet("")
org.apache.spark.sql.AnalysisException: There is a 'path' option set and save() is called with a path parameter. Either remove the path option, or call save() without the parameter. To ignore this check, set 'spark.sql.legacy.pathOptionBehavior.enabled' to 'true'.;

### What changes were proposed in this pull request?
Make MicroBatchExecution explicitly call `getBatch` when the start and end offsets are the same.
### Why are the changes needed?
Structured Streaming micro-batch engine has the contract with V1 data sources that, after a restart, it will call `source.getBatch()` on the last batch attempted before the restart. However, a very rare combination of sequences violates this contract. It occurs only when
- The streaming query has specific types of stateful operations with watermarks (e.g., aggregation in append, mapGroupsWithState with timeouts).
- These queries can execute a batch even without new data when the previous updates the watermark and the stateful ops are such that the new watermark can cause new output/cleanup. Such batches are called no-data-batches.
- The last batch before termination was an incomplete no-data-batch. Upon restart, the micro-batch engine fails to call `source.getBatch` when attempting to re-execute the incomplete no-data-batch.
This occurs because no-data-batches has the same and end offsets, and when a batch is executed, if the start and end offset is same then calling `source.getBatch` is skipped as it is assumed the generated plan will be empty. This only affects V1 data sources like Delta and Autoloader which rely on this invariant to detect in the source whether the query is being started from scratch or restarted.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?

### What changes were proposed in this pull request?
`--` method of `AttributeSet` behave differently under Scala 2.12 and 2.13 because `--` method of `LinkedHashSet` in Scala 2.13 can't maintains the insertion order.
This pr use a Scala 2.12 based code to ensure `--` method of AttributeSet have same behavior under Scala 2.12 and 2.13.
### Why are the changes needed?
The behavior of `AttributeSet` needs to be compatible with Scala 2.12 and 2.13
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Scala 2.12: Pass the Jenkins or GitHub Action
Scala 2.13: Manual test sub-suites of `PlanStabilitySuite`
- **Before** ：293 TESTS FAILED
- **After**：13 TESTS FAILED(The remaining failures are not associated with the current issue)

### What changes were proposed in this pull request?
The purpose of this pr is to partial resolve [SPARK-32808](https://issues.apache.org/jira/browse/SPARK-32808), total of 26 failed test cases were fixed, the related suite as follow:
- `StreamingAggregationSuite` related test cases (2 FAILED -> Pass)
- `GeneratorFunctionSuite` related test cases (2 FAILED -> Pass)
- `UDFSuite` related test cases (2 FAILED -> Pass)
- `SQLQueryTestSuite` related test cases (5 FAILED -> Pass)
- `WholeStageCodegenSuite` related test cases (1 FAILED -> Pass)
- `DataFrameSuite` related test cases (3 FAILED -> Pass)
- `OrcV1QuerySuite\OrcV2QuerySuite` related test cases (4 FAILED -> Pass)
- `ExpressionsSchemaSuite` related test cases (1 FAILED -> Pass)
- `DataFrameStatSuite` related test cases (1 FAILED -> Pass)
- `JsonV1Suite\JsonV2Suite\JsonLegacyTimeParserSuite` related test cases (6 FAILED -> Pass)
The main change of this pr as following:
- Fix Scala 2.13 compilation problems in `ShuffleBlockFetcherIterator` and `Analyzer`
- Specified `Seq` to `scala.collection.Seq` in `objects.scala` and `GenericArrayData` because internal use `Seq` maybe `mutable.ArraySeq` and not easy to call `.toSeq`
- Should specified `Seq` to `scala.collection.Seq` when we call `Row.getAs[Seq]` and `Row.get(i).asInstanceOf[Seq]` because the data maybe `mutable.ArraySeq` but `Seq` is `immutable.Seq` in Scala 2.13
- Use a compatible way to let `+` and `-` method of `Decimal` having the same behavior in Scala 2.12 and Scala 2.13
- Call `toList` in `RelationalGroupedDataset.toDF` method when `groupingExprs` is `Stream` type because `Stream` can't serialize in Scala 2.13
- Add a manual sort to `classFunsMap` in `ExpressionsSchemaSuite` because `Iterable.groupBy` in Scala 2.13 has different result with `TraversableLike.groupBy` in Scala 2.12
### Why are the changes needed?
We need to support a Scala 2.13 build.
### Does this PR introduce _any_ user-facing change?

### What changes were proposed in this pull request?
In the PR, I propose to move the test `SPARK-32810: CSV and JSON data sources should be able to read files with escaped glob metacharacter in the paths` from `DataFrameReaderWriterSuite` to `CSVSuite` and to `JsonSuite`. This will allow to run the same test in `CSVv1Suite`/`CSVv2Suite` and in `JsonV1Suite`/`JsonV2Suite`.

Based on the discussion in [comment](https://github.com/apache/spark/pull/29589#discussion_r484657207), propagation for thread local properties in `SubqueryBroadcastExec` is not necessary, since they will be propagated by broadcast exchange threads anyway.

### What changes were proposed in this pull request?
This is a Spark 3.0 regression introduced by https://github.com/apache/spark/pull/26761. We missed a corner case that `java.lang.Double.compare` treats 0.0 and -0.0 as different, which breaks SQL semantic.
This PR adds back the `OrderingUtil`, to provide custom compare methods that take care of 0.0 vs -0.0
### Why are the changes needed?
Fix a correctness bug.

This is a followup of https://github.com/apache/spark/pull/29485
It moves the plan rewriting methods from `Analyzer` to `QueryPlan`, so that it can work with `SparkPlan` as well. This PR also does an improvement to support a corner case (The attribute to be replace stays together with an unresolved attribute), and make it more general, so that `WidenSetOperationTypes` can rewrite the plan in one shot like before.

### What changes were proposed in this pull request?
In the PR, I propose to fix an issue with the CSV and JSON data sources in Spark SQL when both of the following are true:
* no user specified schema
* some file paths contain escaped glob metacharacters, such as `[``]`, `{``}`, `*` etc.
### Why are the changes needed?
To fix the issue when the follow two queries try to read from paths `[abc].csv` and `[abc].json`:
```scala
spark.read.csv("""/tmp/\[abc\].csv""").show
spark.read.json("""/tmp/\[abc\].json""").show
```
but would end up hitting an exception:
```

### What changes were proposed in this pull request?
Only copy tags to node with no tags when transforming plans.
### Why are the changes needed?
cloud-fan [made a good point](https://github.com/apache/spark/pull/29593#discussion_r482013121) that it doesn't make sense to append tags to existing nodes when nodes are removed. That will cause such bugs as duplicate rows when deduplicating and repartitioning by the same column with AQE.
```
spark.range(10).union(spark.range(10)).createOrReplaceTempView("v1")
val df = spark.sql("select id from v1 group by id distribute by id")
println(df.collect().toArray.mkString(","))
println(df.queryExecution.executedPlan)
// With AQE
[4],[0],[3],[2],[1],[7],[6],[8],[5],[9],[4],[0],[3],[2],[1],[7],[6],[8],[5],[9]
AdaptiveSparkPlan(isFinalPlan=true)
+- CustomShuffleReader local
+- ShuffleQueryStage 0
+- Exchange hashpartitioning(id#183L, 10), true
+- *(3) HashAggregate(keys=[id#183L], functions=[], output=[id#183L])
+- Union
:- *(1) Range (0, 10, step=1, splits=2)
+- *(2) Range (0, 10, step=1, splits=2)
// Without AQE
[4],[7],[0],[6],[8],[3],[2],[5],[1],[9]
*(4) HashAggregate(keys=[id#206L], functions=[], output=[id#206L])
+- Exchange hashpartitioning(id#206L, 10), true
+- *(3) HashAggregate(keys=[id#206L], functions=[], output=[id#206L])
+- Union
:- *(1) Range (0, 10, step=1, splits=2)
+- *(2) Range (0, 10, step=1, splits=2)
```
It's too expensive to detect node removal so we make a compromise only to copy tags to node with no tags.

### What changes were proposed in this pull request?
Change `CreateFunctionCommand` code that add class check before create function.
### Why are the changes needed?
We have different behavior between create permanent function and temporary function when function class is invaild. e.g.,
```
create function f as 'test.non.exists.udf';
-- Time taken: 0.104 seconds
create temporary function f as 'test.non.exists.udf'
-- Error in query: Can not load class 'test.non.exists.udf' when registering the function 'f', please make sure it is on the classpath;

### What changes were proposed in this pull request?
Currently, Spark Public Rest APIs support Application attemptId except SQL API. This causes `no such app: application_X` issue when the application has `attemptId` (e.g: YARN cluster mode).
Please find existing and supported Rest endpoints with attemptId.
```
// Existing Rest Endpoints
applications/{appId}/sql
applications/{appId}/sql/{executionId}
// Rest Endpoints required support
applications/{appId}/{attemptId}/sql
applications/{appId}/{attemptId}/sql/{executionId}
```
Also fixing following compile warning on `SqlResourceSuite`:
```
[WARNING] [Warn] ~/spark/sql/core/src/test/scala/org/apache/spark/status/api/v1/sql/SqlResourceSuite.scala:67: Reference to uninitialized value edges
```
### Why are the changes needed?
This causes `no such app: application_X` issue when the application has `attemptId`.
### Does this PR introduce _any_ user-facing change?
Not yet because SQL Rest API is being planned to release with `Spark 3.1`.
### How was this patch tested?
1. New Unit tests are added for existing Rest endpoints. `attemptId` seems not coming in `local-mode` and coming in `YARN cluster mode` so could not be added for `attemptId` case (Suggestions are welcome).
2. Also, patch has been tested manually through both Spark Core and History Server Rest APIs.

### What changes were proposed in this pull request?
`sql-expression-schema.md` automatically generated by `ExpressionsSchemaSuite`, but only expressions entries are checked in `ExpressionsSchemaSuite`. So if we manually modify the contents of the file, `ExpressionsSchemaSuite` does not necessarily guarantee the correctness of the it some times. For example, [Spark-24884](https://github.com/apache/spark/pull/27507) added `regexp_extract_all` expression support, and manually modify the `sql-expression-schema.md` but not change the content of `Number of queries` cause file content inconsistency.
Some additional checks have been added to `ExpressionsSchemaSuite` to improve the correctness guarantee of `sql-expression-schema.md` as follow:
- `Number of queries` should equals size of `expressions entries` in `sql-expression-schema.md`
- `Number of expressions that missing example` should equals size of `Expressions missing examples` in `sql-expression-schema.md`
- `MissExamples` from case should same as `expectedMissingExamples` from `sql-expression-schema.md`
### Why are the changes needed?
Ensure the correctness of `sql-expression-schema.md` content.

The whole `DynamicPartitionPruningSuite` takes about 2 min on my laptop (either AE on or off). The slowest tests are `test("simple inner join triggers DPP with mock-up tables")` and `test("cleanup any DPP filter that isn't pushed down due to expression id clashes")`, which totally take about 1 min.
We can reuse existing test tables or use smaller tables to reduce the cost. After that, the two tests takes only about 1 sec in total, leading to 2x speedup for the suite.

### What changes were proposed in this pull request?
This PR intends to fix a bug where references can be missing when adding aliases to widen data types in `WidenSetOperationTypes`. For example,
```
CREATE OR REPLACE TEMPORARY VIEW t3 AS VALUES (decimal(1)) tbl(v);
SELECT t.v FROM (
SELECT v FROM t3
UNION ALL
SELECT v + v AS v FROM t3
) t;
org.apache.spark.sql.AnalysisException: Resolved attribute(s) v#1 missing from v#3 in operator !Project [v#1]. Attribute(s) with the same name appear in the operation: v. Please check if the right attribute(s) are used.;;
!Project [v#1] <------ the reference got missing
+- SubqueryAlias t
+- Union
:- Project [cast(v#1 as decimal(11,0)) AS v#3]
: +- Project [v#1]
: +- SubqueryAlias t3
: +- SubqueryAlias tbl
: +- LocalRelation [v#1]
+- Project [v#2]
+- Project [CheckOverflow((promote_precision(cast(v#1 as decimal(11,0))) + promote_precision(cast(v#1 as decimal(11,0)))), DecimalType(11,0), true) AS v#2]
+- SubqueryAlias t3
+- SubqueryAlias tbl
+- LocalRelation [v#1]
```
In the case, `WidenSetOperationTypes` added the alias `cast(v#1 as decimal(11,0)) AS v#3`, then the reference in the top `Project` got missing. This PR correct the reference (`exprId` and widen `dataType`) after adding aliases in the rule.

### What changes were proposed in this pull request?
This PR changes `AttributeSet` and `ExpressionSet` to maintain the insertion order of the elements. More specifically, we:
- change the underlying data structure of `AttributeSet` from `HashSet` to `LinkedHashSet` to maintain the insertion order.
- `ExpressionSet` already uses a list to keep track of the expressions, however, since it is extending Scala's immutable.Set class, operations such as map and flatMap are delegated to the immutable.Set itself. This means that the result of these operations is not an instance of ExpressionSet anymore, rather it's a implementation picked up by the parent class. We also remove this inheritance from `immutable.Set `and implement the needed methods directly. ExpressionSet has a very specific semantics and it does not make sense to extend `immutable.Set` anyway.
- change the `PlanStabilitySuite` to not sort the attributes, to be able to catch changes in the order of expressions in different runs.
### Why are the changes needed?
Expressions identity is based on the `ExprId` which is an auto-incremented number. This means that the same query can yield a query plan with different expression ids in different runs. `AttributeSet` and `ExpressionSet` internally use a `HashSet` as the underlying data structure, and therefore cannot guarantee the a fixed order of operations in different runs. This can be problematic in cases we like to check for plan changes in different runs.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Passes `PlanStabilitySuite` after regenerating the golden files.

### Why are the changes needed?
Currently, the StreamingRelationV2 is bind with TableProvider. Since the V2 relation is not bound with `DataSource`, to make it more flexible and have better expansibility, it should be moved to the catalyst module and bound with the Table interface. We did a similar thing for DataSourceV2Relation.
