### What changes were proposed in this pull request?
This PR proposes applying `black` to pandas API on Spark codes, for improving static analysis.
By executing the `./dev/reformat-python` in the spark home directory, all the code of the pandas API on Spark is fixed according to the static analysis rules.
### Why are the changes needed?
This can be reduces the cost of static analysis during development.
It has been used continuously for about a year in the Koalas project and its convenience has been proven.
### Does this PR introduce _any_ user-facing change?
No, it's dev-only.
### How was this patch tested?
Manually reformat the pandas API on Spark codes by running the `./dev/reformat-python`, and checked the `./dev/lint-python` is passed.

### What changes were proposed in this pull request?
This PR proposes to update `dev/requirement.txt` file.
NOTE that:
- This file isn't used anywhere in Apache Spark CI. It's just for convenience
- To minimize the overhead of maintenance, I removed all lowerbounds of dependencies, which means that using the latest versions of them should work in the clean environment (e.g., you can reinstall all of them).
### Why are the changes needed?
To note the dependencies needed for Spark dev, and for easier env setting up.
### Does this PR introduce _any_ user-facing change?
No, dev-only.
### How was this patch tested?
Logically derived from setup.py, and other places like CI

### What changes were proposed in this pull request?
This PR adds rules to `checkstyle.xml` and `scalastyle-config.xml` to avoid introducing `Objects.toStringHelper` a Guava's API which is no longer present in newer Guava.
### Why are the changes needed?
SPARK-30272 (#26911) replaced `Objects.toStringHelper` which is an APIs Guava 14 provides with `commons.lang3` API because `Objects.toStringHelper` is no longer present in newer Guava.
But toStringHelper was introduced into Spark again and replaced them in SPARK-35420 (#32567).
I think it's better to have a style rule to avoid such repetition.
SPARK-30272 replaced some APIs aside from `Objects.toStringHelper` but `Objects.toStringHelper` seems to affect Spark for now so I add rules only for it.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
I confirmed that `lint-java` and `lint-scala` detect the usage of `toStringHelper` and let the lint check fail.
```

### What changes were proposed in this pull request?
This PR proposes to remove PySpark documentation build in linter check because:
- to speed up CI build by removing duplicate documentation build (linter and doc build)
- for https://github.com/apache/spark/pull/32726. With this PR PySpark documentation build requires a full Spark build to generate plot images in PySpark documentation. It makes less sense to require it in Python linter.
- to remove unnecessary dependency installation for Python linter in CI
### Why are the changes needed?
Python linter script includes documentation build. Because of this, we run documentation builds duplicately in CI, and requires unnecessary dependencies to be installed, and takes extra time. It would more make sense to exclude this in Python linter.
### Does this PR introduce _any_ user-facing change?
No, dev-only.
### How was this patch tested?

### What changes were proposed in this pull request?
BinaryType, which represents byte sequence values in Spark, doesn't support data-type-based operations yet. We are going to introduce BinaryOps for it.
### Why are the changes needed?
The data-type-based-operations class should be set for each individual data type, including BinaryType.
In addition, BinaryType has its special way of addition, which means concatenation.
### Does this PR introduce _any_ user-facing change?
Yes.

### What changes were proposed in this pull request?
The PR is proposed to introduce ArrayOps, MapOps and StructOps to handle data-type-based operations for StructType, ArrayType, and MapType separately.
### Why are the changes needed?
StructType, ArrayType, and MapType are not accepted by DataTypeOps now.
We should handle these complex types. Among them:
- ArrayType supports concatenation: for example, ps.Series([[1,2,3]]) + ps.Series([[4,5,6]]) should work the same as pd.Series([[1,2,3]]) + pd.Series([[4,5,6]]), as concatenation.
- StructOps will be helpful to make to/from pandas conversion data-type-based.

Yes.

### What changes were proposed in this pull request?
The PR is proposed for **pandas APIs on Spark**, in order to separate arithmetic operations shown as below into data-type-based structures.
`__add__, __sub__, __mul__, __truediv__, __floordiv__, __pow__, __mod__,
__radd__, __rsub__, __rmul__, __rtruediv__, __rfloordiv__, __rpow__,__rmod__`
DataTypeOps and subclasses are introduced.
The existing behaviors of each arithmetic operation should be preserved.
### Why are the changes needed?
Currently, the same arithmetic operation of all data types is defined in one function, so it’s difficult to extend the behavior change based on the data types.
Introducing DataTypeOps would be the foundation for [pandas APIs on Spark: Separate basic operations into data type based structures.](https://docs.google.com/document/d/12MS6xK0hETYmrcl5b9pX5lgV4FmGVfpmcSKq--_oQlc/edit?usp=sharing).

### What changes were proposed in this pull request?
This PR proposes to bump up the janino version from 3.0.16 to v3.1.4.
The major changes of this upgrade are as follows:
- Fixed issue #131: Janino 3.1.2 is 10x slower than 3.0.11: The Compiler's IClassLoader was initialized way too eagerly, thus lots of classes were loaded from the class path, which is very slow.
- Improved the encoding of stack map frames according to JVMS11 4.7.4: Previously, only "full_frame"s were generated.
- Fixed issue #107: Janino requires "org.codehaus.commons.compiler.io", but commons-compiler does not export this package
- Fixed the promotion of the array access index expression (see JLS7 15.13 Array Access Expressions).
For all the changes, please see the change log: http://janino-compiler.github.io/janino/changelog.html
NOTE1: I've checked that there is no obvious performance regression. For all the data, see a link: https://docs.google.com/spreadsheets/d/1srxT9CioGQg1fLKM3Uo8z1sTzgCsMj4pg6JzpdcG6VU/edit?usp=sharing
NOTE2: We upgraded janino to 3.1.2 (#27860) once before, but the commit had been reverted in #29495 because of the correctness issue. Recently, #32374 had checked if Spark could land on v3.1.3 or not, but a new bug was found there. These known issues has been fixed in v3.1.4 by following PRs:
- janino-compiler/janino#145
- janino-compiler/janino#146
### Why are the changes needed?
janino v3.0.X is no longer maintained.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?

### What changes were proposed in this pull request?
This patch proposes to increase the maximum heap memory setting for release build.
### Why are the changes needed?
When I was cutting RCs for 2.4.8, I frequently encountered OOM during building using mvn. It happens many times until I increased the heap memory setting.
I am not sure if other release managers encounter the same issue. So I propose to increase the heap memory setting and see if it looks good for others.
### Does this PR introduce _any_ user-facing change?
No, dev only.
### How was this patch tested?
Manually used it during cutting RCs of 2.4.8.

### What changes were proposed in this pull request?
This PR proposes to add linter for JavaScript source files.
[ESLint](https://eslint.org/) seems to be a popular linter for JavaScript so I choose it.
### Why are the changes needed?
Linter enables us to check style and keeps code clean.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Manually run `dev/lint-js` (Node.js and npm are required).
In this PR, mainly indentation style is also fixed an linter passes.

### What changes were proposed in this pull request?
SPARK-10498 added the initial Jira client requirement with 1.0.3 five year ago (2016 January). As of today, it causes `dev/merge_spark_pr.py` failure with `Python 3.9.4` due to this old dependency. This PR aims to upgrade it to the latest version, 2.0.0. The latest version is also a little old (2018 July).
- https://pypi.org/project/jira/#history
### Why are the changes needed?
`Jira==2.0.0` works well with both Python 3.8/3.9 while `Jira==1.0.3` fails with Python 3.9.

### What changes were proposed in this pull request?
This PR proposes to leverage the GitHub Actions resources from the forked repositories instead of using the resources in ASF organisation at GitHub.
This is how it works:
1. "Build and test" (`build_and_test.yml`) triggers a build on any commit on any branch (except `branch-*.*`), which roughly means:
- The original repository will trigger the build on any commits in `master` branch
- The forked repository will trigger the build on any commit in any branch.
2. The build triggered in the forked repository will checkout the original repository's `master` branch locally, and merge the branch from the forked repository into the original repository's `master` branch locally.
Therefore, the tests in the forked repository will run after being sync'ed with the original repository's `master` branch.
3. In the original repository, it triggers a workflow that detects the workflow triggered in the forked repository, and add a comment, to the PR, pointing out the workflow in forked repository.
In short, please see this example HyukjinKwon#34
1. You create a PR and your repository triggers the workflow. Your PR uses the resources allocated to you for testing.
2. Apache Spark repository finds your workflow, and links it in a comment in your PR
**NOTE** that we will still run the tests in the original repository for each commit pushed to `master` branch. This distributes the workflows only in PRs.
### Why are the changes needed?
ASF shares the resources across all the ASF projects, which makes the development slow down.
Please see also:
- Discussion in the buildsa.o mailing list: https://lists.apache.org/x/thread.html/r48d079eeff292254db22705c8ef8618f87ff7adc68d56c4e5d0b4105%3Cbuilds.apache.org%3E
- Infra ticket: https://issues.apache.org/jira/browse/INFRA-21646
By distributing the workflows to use author's resources, we can get around this issue.
### Does this PR introduce _any_ user-facing change?
No, this is a dev-only change.

### What changes were proposed in this pull request?
As a first step of [SPARK-34849](https://issues.apache.org/jira/browse/SPARK-34849), this PR proposes porting the Koalas main code into PySpark.
This PR contains minimal changes to the existing Koalas code as follows:
1. `databricks.koalas` -> `pyspark.pandas`
2. `from databricks import koalas as ks` -> `from pyspark import pandas as pp`
3. `ks.xxx -> pp.xxx`
Other than them:
1. Added a line to `python/mypy.ini` in order to ignore the mypy test. See related issue at [SPARK-34941](https://issues.apache.org/jira/browse/SPARK-34941).
2. Added a comment to several lines in several files to ignore the flake8 F401. See related issue at [SPARK-34943](https://issues.apache.org/jira/browse/SPARK-34943).
When this PR is merged, all the features that were previously used in [Koalas](https://github.com/databricks/koalas) will be available in PySpark as well.
Users can access to the pandas API in PySpark as below:
```python
>>> from pyspark import pandas as pp
>>> ppdf = pp.DataFrame({"A": [1, 2, 3], "B": [15, 20, 25]})
>>> ppdf
A B
0 1 15
1 2 20
2 3 25
```
The existing "options and settings" in Koalas are also available in the same way:
```python
>>> from pyspark.pandas.config import set_option, reset_option, get_option
>>> ppser1 = pp.Series([1, 2, 3])
>>> ppser2 = pp.Series([3, 4, 5])
>>> ppser1 + ppser2
Traceback (most recent call last):
...
ValueError: Cannot combine the series or dataframe because it comes from a different dataframe. In order to allow this operation, enable 'compute.ops_on_diff_frames' option.
>>> set_option("compute.ops_on_diff_frames", True)
>>> ppser1 + ppser2
0 4
1 6
2 8
dtype: int64
```
Please also refer to the [API Reference](https://koalas.readthedocs.io/en/latest/reference/index.html) and [Options and Settings](https://koalas.readthedocs.io/en/latest/user_guide/options.html) for more detail.
**NOTE** that this PR intentionally ports the main codes of Koalas first almost as are with minimal changes because:
- Koalas project is fairly large. Making some changes together for PySpark will make it difficult to review the individual change.
Koalas dev includes multiple Spark committers who will review. By doing this, the committers will be able to more easily and effectively review and drive the development.
- Koalas tests and documentation require major changes to make it look great together with PySpark whereas main codes do not require.
- We lately froze the Koalas codebase, and plan to work together on the initial porting. By porting the main codes first as are, it unblocks the Koalas dev to work on other items in parallel.
I promise and will make sure on:
- Rename Koalas to PySpark pandas APIs and/or pandas-on-Spark accordingly in documentation, and the docstrings and comments in the main codes.
- Triage APIs to remove that don’t make sense when Koalas is in PySpark
The documentation changes will be tracked in [SPARK-34885](https://issues.apache.org/jira/browse/SPARK-34885), the test code changes will be tracked in [SPARK-34886](https://issues.apache.org/jira/browse/SPARK-34886).

### What changes were proposed in this pull request?
This PR fixes the build failure with Scala 2.13 which is related to `commons-cli`.
The last few days, build with Scala 2.13 on GA continues to fail and the error message says like as follows.
```
[error] /home/runner/work/spark/spark/sql/hive-thriftserver/src/main/java/org/apache/hive/service/server/HiveServer2.java:26:1: error: package org.apache.commons.cli does not exist
1278[error] import org.apache.commons.cli.GnuParser;
```
The reason is that `mvn help` in `change-scala-version.sh` downloads the POM file of `commons-cli` but doesn't download the JAR file, leading the build failure.
This PR also adds `commons-cli` to the dependencies explicitly because HiveThriftServer depends on it.
### Why are the changes needed?
Expect to fix the build failure with Scala 2.13.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
I confirmed that build successfully finishes with Scala 2.13 on my laptop.

### What changes were proposed in this pull request?
The `change-scala-version.sh` script updates Scala versions across the build for cross-build purposes. It manually changes `scala.binary.version` but not `scala.version`.
### Why are the changes needed?
It seems that this has always been an oversight, and the cross-built builds of Spark have an incorrect scala.version. See 2.4.5's 2.12 POM for example, which shows a Scala 2.11 version.

### What changes were proposed in this pull request?
Cleanup all Zinc standalone server code, and realated coniguration.
### Why are the changes needed?
- Zinc is the incremental compiler to speed up builds of compilation.
- The scala-maven-plugin is the mave plugin, which is used by Spark, one of the function is to integrate the Zinc to enable the incremental compiler.
- Since Spark v3.0.0 ([SPARK-28759](https://issues.apache.org/jira/browse/SPARK-28759)), the scala-maven-plugin is upgraded to v4.X, that means Zinc v0.3.13 standalone server is useless anymore.
However, we still download, install, start the standalone Zinc server. we should remove all zinc standalone server code, and all related configuration.
See more in [SPARK-34539](https://issues.apache.org/jira/projects/SPARK/issues/SPARK-34539) or the doc [Zinc standalone server is useless after scala-maven-plugin 4.x](https://docs.google.com/document/d/1u4kCHDx7KjVlHGerfmbcKSB0cZo6AD4cBdHSse-SBsM).
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Run any mvn build:
./build/mvn -DskipTests clean package -pl core
You could see the increamental compilation is still working, the stage of "scala-maven-plugin:4.3.0:compile (scala-compile-first)" with incremental compilation info, like:
```

### What changes were proposed in this pull request?
This PR fixes an issue that `bundler exec jekyll` build fails to generate Scala API docs even though after `dev/change-scala-version.sh 2.13` run.
### Why are the changes needed?
The reason of this issue is that `build/sbt` in `copy_api_dirs.rb` runs without `-Pscala-2.13`.
So, it's a bug.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
I tested the following patterns manually.
* `dev/change-scala-version 2.13` and then `bundler exec jekyll build`
* `dev/change-scala-version 2.12` to change back to Scala 2.12 and then `bundler exec jekyll build`
* `dev/change-scala-version 2.13` two times to confirm the idempotency and then `bundler exec jekyll build`

### What changes were proposed in this pull request?
This adds `hadoop-yarn-server-web-proxy` as dependency for Yarn and Hadoop 3.x profile (it is already a dependency for 2.x). Also excludes some dependencies from the module which are already covered by other Hadoop jars used by Spark.
### Why are the changes needed?
The class `org.apache.hadoop.yarn.server.webproxy.amfilter.AmIpFilter` is used by `ApplicationMaster`:
```scala
private def addAmIpFilter(driver: Option[RpcEndpointRef], proxyBase: String) = {
val amFilter = "org.apache.hadoop.yarn.server.webproxy.amfilter.AmIpFilter"
val params = client.getAmIpFilterParams(yarnConf, proxyBase)
driver match {
case Some(d) =>
d.send(AddWebUIFilter(amFilter, params, proxyBase))
...
```
and will be loaded at runtime. Therefore, without the above jar Spark Yarn app will fail with `ClassNotFoundError`.

```
Spark uses `GITHUB_OAUTH_KEY` for GitHub token, but `translate-contributors.py` script alone uses `GITHUB_API_TOKEN`. We should better match to make it easier to run the script

### What changes were proposed in this pull request?
Improving the documentation and release process by pinning Jekyll version by Gemfile and Bundler.
Some files and their responsibilities within this PR:
- `docs/.bundle/config` is used to specify a directory "docs/.local_ruby_bundle" which will be used as destination to install the ruby packages into instead of the global one which requires root access
- `docs/Gemfile` is specifying the required Jekyll version and other top level gem versions
- `docs/Gemfile.lock` is generated by the "bundle install". This file contains the exact resolved versions of all the gems including the top level gems and all the direct and transitive dependencies of those gems. When this file is generated it contains a platform related section "PLATFORMS" (in my case after the generation it was "universal-darwin-19"). Still this file must be under version control as when the version of a gem does not fit to the one specified in `Gemfile` an error comes (i.e. if the `Gemfile.lock` was generated for Jekyll 4.1.0 and its version is updated in the `Gemfile` to 4.2.0 then it triggers the error: "The bundle currently has jekyll locked at 4.1.0."). This is solution is also suggested officially in [its documentation](https://bundler.io/rationale.html#checking-your-code-into-version-control). To get rid of the specific platform (like "universal-darwin-19") first we have to add "ruby" as platform [which means this should work on every platform where Ruby runs](https://guides.rubygems.org/what-is-a-gem/)) by running "bundle lock --add-platform ruby" then the specific platform can be removed by "bundle lock --remove-platform universal-darwin-19".
After this the correct process to update Jekyll version is the following:
1. update the version in `Gemfile`
2. run "bundle update" which updates the `Gemfile.lock`
3. commit both files
This process for version update is tested for details please check the testing section.
### Why are the changes needed?
Using different Jekyll versions can generate different output documents.
This PR standardize the process.
### Does this PR introduce _any_ user-facing change?
No, assuming the release was done via docker by using `do-release-docker.sh`.
In that case there should be no difference at all as the same Jekyll version is specified in the Gemfile.
### How was this patch tested?
#### Testing document generation
Doc generation step was triggered via the docker release:
```
$ ./do-release-docker.sh -d ~/working -n -s docs

#### Testing Jekyll (or other gem) update
First locally I reverted Jekyll to 4.1.0:
```
$ rm Gemfile.lock
$ rm -rf .local_ruby_bundle
# edited Gemfile to use version 4.1.0
$ cat Gemfile
source "https://rubygems.org"
gem "jekyll", "4.1.0"
gem "rouge", "3.26.0"
gem "jekyll-redirect-from", "0.16.0"
gem "webrick", "1.7"
$ bundle install
...
```
Testing Jekyll version before the update:
```
$ bundle exec jekyll --version
jekyll 4.1.0
```
Imitating Jekyll update coming from git by reverting my local changes:
```
$ git checkout Gemfile
Updated 1 path from the index
$ cat Gemfile
source "https://rubygems.org"
gem "jekyll", "4.2.0"
gem "rouge", "3.26.0"
gem "jekyll-redirect-from", "0.16.0"
gem "webrick", "1.7"
$ git checkout Gemfile.lock
Updated 1 path from the index
```
Run the install:
```
$ bundle install
...
```
Checking the updated Jekyll version:
```
$ bundle exec jekyll --version
jekyll 4.2.0
```

### What changes were proposed in this pull request?
This PR aims to fix the Scala 2.12 release profile in `release-build.sh`.
### Why are the changes needed?
Since 3.0.0 (SPARK-26132), the release script is using `SCALA_2_11_PROFILES` to publish Scala 2.12 artifacts.
After looking at the code, this is not a blocker because `-Pscala-2.11` is no-op in `branch-3.x`.
In addition `scala-2.12` profile is enabled by default and it's an empty profile without any configuration technically.
### Does this PR introduce _any_ user-facing change?
No.

### What changes were proposed in this pull request?
This:
1. switches Spark to use shaded Hadoop clients, namely hadoop-client-api and hadoop-client-runtime, for Hadoop 3.x.
2. upgrade built-in version for Hadoop 3.x to Hadoop 3.2.2
Note that for Hadoop 2.7, we'll still use the same modules such as hadoop-client.
In order to still keep default Hadoop profile to be hadoop-3.2, this defines the following Maven properties:
```
hadoop-client-api.artifact
hadoop-client-runtime.artifact
hadoop-client-minicluster.artifact
```
which default to:
```
hadoop-client-api
hadoop-client-runtime
hadoop-client-minicluster
```
but all switch to `hadoop-client` when the Hadoop profile is hadoop-2.7. A side affect from this is we'll import the same dependency multiple times. For this I have to disable Maven enforcer `banDuplicatePomDependencyVersions`.
Besides above, there are the following changes:
- explicitly add a few dependencies which are imported via transitive dependencies from Hadoop jars, but are removed from the shaded client jars.
- removed the use of `ProxyUriUtils.getPath` from `ApplicationMaster` which is a server-side/private API.
- modified `IsolatedClientLoader` to exclude `hadoop-auth` jars when Hadoop version is 3.x. This change should only matter when we're not sharing Hadoop classes with Spark (which is _mostly_ used in tests).
### Why are the changes needed?
Hadoop 3.2.2 is released with new features and bug fixes, so it's good for the Spark community to adopt it. However, latest Hadoop versions starting from Hadoop 3.2.1 have upgraded to use Guava 27+. In order to resolve Guava conflicts, this takes the approach by switching to shaded client jars provided by Hadoop. This also has the benefits of avoid pulling other 3rd party dependencies from Hadoop side so as to avoid more potential future conflicts.
### Does this PR introduce _any_ user-facing change?
When people use Spark with `hadoop-provided` option, they should make sure class path contains `hadoop-client-api` and `hadoop-client-runtime` jars. In addition, they may need to make sure these jars appear before other Hadoop jars in the order. Otherwise, classes may be loaded from the other non-shaded Hadoop jars and cause potential conflicts.

org.apache.spark.sql.hive.thriftserver.HiveThriftHttpServerSuite.JDBC query execution
org.apache.spark.sql.hive.thriftserver.HiveThriftHttpServerSuite.Checks Hive version
org.apache.spark.sql.hive.thriftserver.HiveThriftHttpServerSuite.SPARK-24829 Checks cast as float
```
The root cause here is a jar conflict issue.
`NewCookie.isHttpOnly` is not defined in the `jsr311-api.jar` which conflicts
The transitive artifact `jsr311-api.jar` of `hadoop-client` is excluded at the maven side. See https://issues.apache.org/jira/browse/SPARK-27179.
The Jenkins PR builder and Github Action use `SBT` as the compiler tool.
First, the exclusion rule from maven is not followed by sbt, so I was able to see `jsr311-api.jar` from maven cache to be added to the classpath directly. **This seems to be a bug of `sbt-pom-reader` plugin but I'm not that sure.**
Then I added an `ExcludeRule` for the `hive-thriftserver` module at the SBT side and did see the `jsr311-api.jar` gone, but the CI jobs still failed with the same error.
I added a trace log in ThriftHttpServlet
```s
ERROR ThriftHttpServlet: !!!!!!!!! Suspect???????? --->
file:/home/jenkins/workspace/SparkPullRequestBuilder/assembly/target/scala-2.12/jars/jsr311-api-1.1.1.jar
```
And the log pointed out that the assembly phase copied it to `assembly/target/scala-2.12/jars/` which will be added to the classpath too. With the help of SBT `dependencyTree` tool, I saw the `jsr311-api` again as a transitive of `jersery-core` from `yarn` module with a `test` scope. So **This seems to be another bug from the SBT side of the `sbt-assembly` plugin.** It copied a test scope transitive artifact to the assembly output.
In this PR, I defined some rules in SparkBuild.scala to bypass the potential bugs from the SBT side.
First, exclude the `jsr311` from all over the project and then add it back separately to the YARN module for SBT.
Additionally, the HiveThriftServerSuites was reflected for reducing flakiness too, but not related to the bugs I have found so far.
