### What changes were proposed in this pull request?
This PR reverts https://github.com/apache/spark/pull/26051 and https://github.com/apache/spark/pull/26066
### Why are the changes needed?
There is no standard requiring that `size(null)` must return null, and returning -1 looks reasonable as well. This is kind of a cosmetic change and we should avoid it if it breaks existing queries. This is similar to reverting TRIM function parameter order change.
### Does this PR introduce any user-facing change?
Yes, change the behavior of `size(null)` back to be the same as 2.4.

### What changes were proposed in this pull request?
This PR makes `dev/make-distribution.sh` a bit easier to use by not hiding errors thrown by Maven.
As a supporting change, this PR also suppresses progress bar output from curl and wget that may be output from within `build/mvn`.
### Why are the changes needed?
It's surprising for command-line options to be position-dependent. The errors that get thrown when you pass the correct option (like `--pip`) but in the wrong order are confusing.
### Does this PR introduce any user-facing change?
No.
### How was this patch tested?
I ran a few invocations of `make-distribution.sh` to confirm that, when passed incorrect options, I can actually see the errors thrown directly by Maven.

### What changes were proposed in this pull request?
In the PR, I propose to change conversion of java.sql.Timestamp/Date values to/from internal values of Catalyst's TimestampType/DateType before cutover day `1582-10-15` of Gregorian calendar. I propose to construct local date-time from microseconds/days since the epoch. Take each date-time component `year`, `month`, `day`, `hour`, `minute`, `second` and `second fraction`, and construct java.sql.Timestamp/Date using the extracted components.
### Why are the changes needed?
This will rebase underlying time/date offset in the way that collected java.sql.Timestamp/Date values will have the same local time-date component as the original values in Gregorian calendar.
Here is the example which demonstrates the issue:
```sql
scala> sql("select date '1100-10-10'").collect()
res1: Array[org.apache.spark.sql.Row] = Array([1100-10-03])
```
### Does this PR introduce any user-facing change?
Yes, after the changes:
```sql
scala> sql("select date '1100-10-10'").collect()
res0: Array[org.apache.spark.sql.Row] = Array([1100-10-10])
```
### How was this patch tested?

### What changes were proposed in this pull request?
When encoding Java Beans to Spark DataFrame, respecting `javax.annotation.Nonnull` and producing non-null fields.
### Why are the changes needed?
When encoding Java Beans to Spark DataFrame, non-primitive types are encoded as nullable fields. Although It works for most cases, it can be an issue under a few situations, e.g. the one described in the JIRA ticket when saving DataFrame to Avro format with non-null field.
We should allow Spark users more flexibility when creating Spark DataFrame from Java Beans. Currently, Spark users cannot create DataFrame with non-nullable fields in the schema from beans with non-nullable properties.
Although it is possible to project top-level columns with SQL expressions like `AssertNotNull` to make it non-null, for nested fields it is more tricky to do it similarly.
### Does this PR introduce any user-facing change?
Yes. After this change, Spark users can use `javax.annotation.Nonnull` to annotate non-null fields in Java Beans when encoding beans to Spark DataFrame.
### How was this patch tested?
Added unit test.

### What changes were proposed in this pull request?
In Spark version 2.4 and earlier, datetime parsing, formatting and conversion are performed by using the hybrid calendar (Julian + Gregorian).
Since the Proleptic Gregorian calendar is de-facto calendar worldwide, as well as the chosen one in ANSI SQL standard, Spark 3.0 switches to it by using Java 8 API classes (the java.time packages that are based on ISO chronology ). The switching job is completed in SPARK-26651.
But after the switching, there are some patterns not compatible between Java 8 and Java 7, Spark needs its own definition on the patterns rather than depends on Java API.
In this PR, we achieve this by writing the document and shadow the incompatible letters. See more details in [SPARK-31030](https://issues.apache.org/jira/browse/SPARK-31030)
### Why are the changes needed?
For backward compatibility.
### Does this PR introduce any user-facing change?
No.
After we define our own datetime parsing and formatting patterns, it's same to old Spark version.
### How was this patch tested?
Existing and new added UT.

2. When splitting, it's possible that we create a partition for very small amount of data..
This PR fixes them
1. don't create `PartialReducerPartitionSpec` if we can't split.

### What changes were proposed in this pull request?
RuleExecutor already support metering for analyzer/optimizer rules. By providing such information in `PlanChangeLogger`, user can get more information when debugging rule changes .
This PR enhanced `PlanChangeLogger` to display RuleExecutor metrics. This can be easily done by calling the existing API `resetMetrics` and `dumpTimeSpent`, but there might be conflicts if user is also collecting total metrics of a sql job. Thus I introduced `QueryExecutionMetrics`, as the snapshot of `QueryExecutionMetering`, to better support this feature.
Information added to `PlanChangeLogger`
```
=== Metrics of Executed Rules ===
Total number of runs: 554
Total time: 0.107756568 seconds
Total number of effective runs: 11
Total time of effective runs: 0.047615486 seconds

### What changes were proposed in this pull request?
This PR proposes two things:
1. Convert `null` to `string` type during schema inference of `schema_of_json` as JSON datasource does. This is a bug fix as well because `null` string is not the proper DDL formatted string and it is unable for SQL parser to recognise it as a type string. We should match it to JSON datasource and return a string type so `schema_of_json` returns a proper DDL formatted string.
2. Let `schema_of_json` respect `dropFieldIfAllNull` option during schema inference.
### Why are the changes needed?
To let `schema_of_json` return a proper DDL formatted string, and respect `dropFieldIfAllNull` option.
### Does this PR introduce any user-facing change?
Yes, it does.
```scala
import collection.JavaConverters._
import org.apache.spark.sql.functions._
spark.range(1).select(schema_of_json(lit("""{"id": ""}"""))).show()
spark.range(1).select(schema_of_json(lit("""{"id": "a", "drop": {"drop": null}}"""), Map("dropFieldIfAllNull" -> "true").asJava)).show(false)
```
**Before:**
```

**After:**

### What changes were proposed in this pull request?
I've applied following changed to StagePage.
1. Added `Shuffle Write Time` to task metrics summary.
2. Added checkbox for `Shuffle Write Time` as an additional metrics.
3. Renamed `Write Time` column in task table to `Shuffle Write Time` and let it as an additional column.
### Why are the changes needed?
Task metrics summary doesn't show `Shuffle Write Time` even though it shows `Shuffle Read Blocked Time`.
`Shuffle Read Blocked Time` is let as an additional metrics so I also let `Shuffle Write Time` as an other additional metrics.
### Does this PR introduce any user-facing change?
Yes. After this change, task metrics summary can show `Shuffle Write Time` and its visibility is controlled by a checkbox.
`Write Time` column is already shown in task table but the title is ambiguous so I've renamed it as `Shuffle Write Time`.

This PR makes the following refinements to the workflow for building docs:
* Install Python and Ruby consistently using pyenv and rbenv across both the docs README and the release Dockerfile.
* Pin the Python and Ruby versions we use.
* Pin all direct Python and Ruby dependency versions.
* Eliminate any use of `sudo pip`, which the Python community discourages, or `sudo gem`.
### Why are the changes needed?

### What changes were proposed in this pull request?
This pr intends to support 32 or more grouping attributes for GROUPING_ID. In the current master, an integer overflow can occur to compute grouping IDs;
e75d9afb2f/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/plans/logical/basicLogicalOperators.scala (L613)
For example, the query below generates wrong grouping IDs in the master;
```
scala> val numCols = 32 // or, 31
scala> val cols = (0 until numCols).map { i => s"c$i" }
scala> sql(s"create table test_$numCols (${cols.map(c => s"$c int").mkString(",")}, v int) using parquet")
scala> val insertVals = (0 until numCols).map { _ => 1 }.mkString(",")
scala> sql(s"insert into test_$numCols values ($insertVals,3)")
scala> sql(s"select grouping_id(), sum(v) from test_$numCols group by grouping sets ((${cols.mkString(",")}), (${cols.init.mkString(",")}))").show(10, false)
scala> sql(s"drop table test_$numCols")
// numCols = 32
+-------------+------+
|grouping_id()|sum(v)|
+-------------+------+
|0 |3 |
|0 |3 | // Wrong Grouping ID
+-------------+------+
// numCols = 31
+-------------+------+
|grouping_id()|sum(v)|
+-------------+------+
|0 |3 |
|1 |3 |

Add `OrcV2QuerySuite` which explicitly sets the configuration `USE_V1_SOURCE_LIST` as `""` to use ORC V2 implementation.
### Why are the changes needed?
As now file source V2 is disabled by default, the test suite `OrcQuerySuite` is testing V1 implementation as well as the `OrcV1QuerySuite`. We should fix it.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Unit test.

### What changes were proposed in this pull request?
Use scala annotation deprecate to deprecate untyped scala UDF.
### Why are the changes needed?
After #27488, it's weird to see the untyped scala UDF will fail by default without deprecation.
### Does this PR introduce any user-facing change?
Yes, user will see the warning:
```
<console>:26: warning: method udf in object functions is deprecated (since 3.0.0): Untyped Scala UDF API is deprecated, please use typed Scala UDF API such as 'def udf[RT: TypeTag](f: Function0[RT]): UserDefinedFunction' instead.
val myudf = udf(() => Math.random(), DoubleType)

```
### How was this patch tested?
Tested manually.

### What changes were proposed in this pull request?
In the PR, I propose:
1. To replace matching by `Literal` in `ExprUtils.evalSchemaExpr()` to checking foldable property of the `schema` expression.
2. To replace matching by `Literal` in `ExprUtils.evalTypeExpr()` to checking foldable property of the `schema` expression.
3. To change checking of the input parameter in the `SchemaOfCsv` expression, and allow foldable `child` expression.
4. To change checking of the input parameter in the `SchemaOfJson` expression, and allow foldable `child` expression.
### Why are the changes needed?
This should improve Spark SQL UX for `from_csv`/`from_json`. Currently, Spark expects only literals:
```sql
spark-sql> select from_csv('1,Moscow', replace('dpt_org_id INT, dpt_org_city STRING', 'dpt_org_', ''));
Error in query: Schema should be specified in DDL format as a string literal or output of the schema_of_csv function instead of replace('dpt_org_id INT, dpt_org_city STRING', 'dpt_org_', '');; line 1 pos 7
spark-sql> select from_json('{"id":1, "city":"Moscow"}', replace('dpt_org_id INT, dpt_org_city STRING', 'dpt_org_', ''));
Error in query: Schema should be specified in DDL format as a string literal or output of the schema_of_json function instead of replace('dpt_org_id INT, dpt_org_city STRING', 'dpt_org_', '');; line 1 pos 7
```
and only string literals are acceptable as CSV examples by `schema_of_csv`/`schema_of_json`:
```sql
spark-sql> select schema_of_csv(concat_ws(',', 0.1, 1));
Error in query: cannot resolve 'schema_of_csv(concat_ws(',', CAST(0.1BD AS STRING), CAST(1 AS STRING)))' due to data type mismatch: The input csv should be a string literal and not null; however, got concat_ws(',', CAST(0.1BD AS STRING), CAST(1 AS STRING)).; line 1 pos 7;
'Project [unresolvedalias(schema_of_csv(concat_ws(,, cast(0.1 as string), cast(1 as string))), None)]
+- OneRowRelation
spark-sql> select schema_of_json(regexp_replace('{"item_id": 1, "item_price": 0.1}', 'item_', ''));
Error in query: cannot resolve 'schema_of_json(regexp_replace('{"item_id": 1, "item_price": 0.1}', 'item_', ''))' due to data type mismatch: The input json should be a string literal and not null; however, got regexp_replace('{"item_id": 1, "item_price": 0.1}', 'item_', '').; line 1 pos 7;
'Project [unresolvedalias(schema_of_json(regexp_replace({"item_id": 1, "item_price": 0.1}, item_, )), None)]
+- OneRowRelation
```
### Does this PR introduce any user-facing change?
Yes, after the changes users can pass any foldable string expression as the `schema` parameter to `from_csv()/from_json()`. For the example above:
```sql
spark-sql> select from_csv('1,Moscow', replace('dpt_org_id INT, dpt_org_city STRING', 'dpt_org_', ''));
{"id":1,"city":"Moscow"}
spark-sql> select from_json('{"id":1, "city":"Moscow"}', replace('dpt_org_id INT, dpt_org_city STRING', 'dpt_org_', ''));
{"id":1,"city":"Moscow"}
```
After change the `schema_of_csv`/`schema_of_json` functions accept foldable expressions, for example:
```sql
spark-sql> select schema_of_csv(concat_ws(',', 0.1, 1));
struct<_c0:double,_c1:int>
spark-sql> select schema_of_json(regexp_replace('{"item_id": 1, "item_price": 0.1}', 'item_', ''));
struct<id:bigint,price:double>
```
### How was this patch tested?

### Why are the changes needed?
For backward compatibility, SPARK-28093 is reverted. However, from Apache Spark 3.0.0, we should give a safe guideline to use SQL syntax instead of the esoteric function signatures.

### What changes were proposed in this pull request?
This PR proposes to respect hidden parameters by using `stringArgs` in `Expression.toString `. By this, we can show the strings properly in some cases such as `NonSQLExpression`.
### Why are the changes needed?
To respect "hidden" arguments in the string representation.
### Does this PR introduce any user-facing change?
Yes, for example, on the top of https://github.com/apache/spark/pull/27657,
```scala
val identify = udf((input: Seq[Int]) => input)
spark.range(10).select(identify(array("id"))).show()
```
shows hidden parameter `useStringTypeWhenEmpty`.
```
+---------------------+
|UDF(array(id, false))|
+---------------------+
| [0]|
| [1]|
...
```
whereas:
```scala
spark.range(10).select(array("id")).show()
```
```
+---------+
|array(id)|
+---------+
| [0]|
| [1]|
...
```
### How was this patch tested?
Manually tested as below:
```scala
val identify = udf((input: Boolean) => input)
spark.range(10).select(identify(exists(array(col("id")), _ % 2 === 0))).show()
```
Before:
```
+-------------------------------------------------------------------------------------+
|UDF(exists(array(id), lambdafunction(((lambda 'x % 2) = 0), lambda 'x, false), true))|
+-------------------------------------------------------------------------------------+
| true|
| false|
| true|
...
```
After:
```
+-------------------------------------------------------------------------------+
|UDF(exists(array(id), lambdafunction(((lambda 'x % 2) = 0), lambda 'x, false)))|

### What changes were proposed in this pull request?
This PR propose
1. Explicitly include xml-apis. xml-apis is already the part of xerces 2.12.0 (https://repo1.maven.org/maven2/xerces/xercesImpl/2.12.0/xercesImpl-2.12.0.pom). However, we're excluding it by setting `scope` to `test`. This seems causing `spark-shell`, built from Maven, to fail.
Seems like previously xml-apis wasn't reached for some reasons but after we upgrade, it seems requiring. Therefore, this PR proposes to include it.
2. Pins `xerces` version in SBT as well. Seems this dependency is resolved differently from Maven.
Note that Hadoop 3 does not looks requiring this as they replaced xerces as of [HDFS-12221](https://issues.apache.org/jira/browse/HDFS-12221).
### Why are the changes needed?
To make `spark-shell` working from Maven build, and uses the same xerces version.
### Does this PR introduce any user-facing change?
No, it's master only.
### How was this patch tested?
**1.**
```bash
./build/mvn -DskipTests -Psparkr -Phive clean package
