### 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?
The `LiteralGenerator` is mostly used in the `checkConsistencyBetweenInterpretedAndCodegen` method in `MathExpressionsSuite`. This change would have caught the bug fixed in #29495 .

### What changes were proposed in this pull request?
Add a new config `spark.sql.maxMetadataStringLength`. This config aims to limit metadata value length, e.g. file location.
### Why are the changes needed?
Some metadata have been abbreviated by `...` when I tried to add some test in `SQLQueryTestSuite`. We need to replace such value to `notIncludedMsg`. That caused we can't replace that like location value by `className` since the `className` has been abbreviated.
Here is a case:
```

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

### 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.

### 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`. To get aware of these failures quickly, I think its worth setting `CODEGEN_ONLY` at `CODEGEN_FACTORY_MODE`.

### 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()
```
### Does this PR introduce _any_ user-facing change?
No. This is a test-only change.

### 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.
### Why are the changes needed?

### What changes were proposed in this pull request?
This PR changes the behavior of RangeExec with WholeStageCodegen disabled or falled back to change the number of partitions to zero when a range is empty.
In the current master, if WholeStageCodegen effects, the number of partitions of an empty range will be changed to zero.
```
spark.range(1, 1, 1, 1000).rdd.getNumPartitions
res0: Int = 0
```
But it doesn't if WholeStageCodegen is disabled or falled back.
```
spark.conf.set("spark.sql.codegen.wholeStage", false)
spark.range(1, 1, 1, 1000).rdd.getNumPartitions

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

### 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.
### How was this patch tested?
Jenkins test will follow.

### What changes were proposed in this pull request?
Upgrade Apache Arrow to version 1.0.1 for the Java dependency and increase minimum version of PyArrow to 1.0.0.
This release marks a transition to binary stability of the columnar format (which was already informally backward-compatible going back to December 2017) and a transition to Semantic Versioning for the Arrow software libraries. Also note that the Java arrow-memory artifact has been split to separate dependence on netty-buffer and allow users to select an allocator. Spark will continue to use `arrow-memory-netty` to maintain performance benefits.
Version 1.0.0 - 1.0.0 include the following selected fixes/improvements relevant to Spark users:
ARROW-9300 - [Java] Separate Netty Memory to its own module
ARROW-9272 - [C++][Python] Reduce complexity in python to arrow conversion
ARROW-9016 - [Java] Remove direct references to Netty/Unsafe Allocators
ARROW-8664 - [Java] Add skip null check to all Vector types
ARROW-8485 - [Integration][Java] Implement extension types integration
ARROW-8434 - [C++] Ipc RecordBatchFileReader deserializes the Schema multiple times
ARROW-8314 - [Python] Provide a method to select a subset of columns of a Table
ARROW-8230 - [Java] Move Netty memory manager into a separate module
ARROW-8229 - [Java] Move ArrowBuf into the Arrow package
ARROW-7955 - [Java] Support large buffer for file/stream IPC
ARROW-7831 - [Java] unnecessary buffer allocation when calling splitAndTransferTo on variable width vectors
ARROW-6111 - [Java] Support LargeVarChar and LargeBinary types and add integration test with C++
ARROW-6110 - [Java] Support LargeList Type and add integration test with C++
ARROW-5760 - [C++] Optimize Take implementation
ARROW-300 - [Format] Add body buffer compression option to IPC message protocol using LZ4 or ZSTD
ARROW-9098 - RecordBatch::ToStructArray cannot handle record batches with 0 column
ARROW-9066 - [Python] Raise correct error in isnull()
ARROW-9223 - [Python] Fix to_pandas() export for timestamps within structs
ARROW-9195 - [Java] Wrong usage of Unsafe.get from bytearray in ByteFunctionsHelper class
ARROW-7610 - [Java] Finish support for 64 bit int allocations
ARROW-8115 - [Python] Conversion when mixing NaT and datetime objects not working
ARROW-8392 - [Java] Fix overflow related corner cases for vector value comparison
ARROW-8537 - [C++] Performance regression from ARROW-8523

### 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?
New unit test with a mock v1 source that fails without the fix.

- `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.
