### Background
For the current status, the test script that generates coverage information was merged
into Spark, https://github.com/apache/spark/pull/20204
So, we can generate the coverage report and site by, for example:
```
run-tests-with-coverage --python-executables=python3 --modules=pyspark-sql
```
like `run-tests` script in `./python`.
### Proposed change
The next step is to host this coverage report via `github.io` automatically
by Jenkins (see https://spark-test.github.io/pyspark-coverage-site/).
This uses my testing account for Spark, spark-test, which is shared to Felix and Shivaram a long time ago for testing purpose including AppVeyor.
To cut this short, this PR targets to run the coverage in
[spark-master-test-sbt-hadoop-2.7](https://amplab.cs.berkeley.edu/jenkins/job/spark-master-test-sbt-hadoop-2.7/)
In the specific job, it will clone the page, and rebase the up-to-date PySpark test coverage from the latest commit. For instance as below:
```bash
# Clone PySpark coverage site.
git clone https://github.com/spark-test/pyspark-coverage-site.git
# Remove existing HTMLs.
rm -fr pyspark-coverage-site/*
# Copy generated coverage HTMLs.
cp -r .../python/test_coverage/htmlcov/* pyspark-coverage-site/
# Check out to a temporary branch.
git symbolic-ref HEAD refs/heads/latest_branch
# Add all the files.
git add -A
# Commit current HTMLs.
git commit -am "Coverage report at latest commit in Apache Spark"
# Delete the old branch.
git branch -D gh-pages
# Rename the temporary branch to master.
git branch -m gh-pages
# Finally, force update to our repository.
git push -f origin gh-pages
```
So, it is a one single up-to-date coverage can be shown in the `github-io` page. The commands above were manually tested.
### TODOs
- [x] Write a draft HyukjinKwon
- [x] `pip install coverage` to all python implementations (pypy, python2, python3) in Jenkins workers - shaneknapp
- [x] Set hidden `SPARK_TEST_KEY` for spark-test's password in Jenkins via Jenkins's feature
This should be set in both PR builder and `spark-master-test-sbt-hadoop-2.7` so that later other PRs can test and fix the bugs - shaneknapp
- [x] Set an environment variable that indicates `spark-master-test-sbt-hadoop-2.7` so that that specific build can report and update the coverage site - shaneknapp
- [x] Make PR builder's test passed HyukjinKwon
- [x] Fix flaky test related with coverage HyukjinKwon
- 6 consecutive passes out of 7 runs
This PR will be co-authored with me and shaneknapp
## How was this patch tested?
It will be tested via Jenkins.

## What changes were proposed in this pull request?
Upgrade Apache Arrow to version 0.12.0. This includes the Java artifacts and fixes to enable usage with pyarrow 0.12.0
Version 0.12.0 includes the following selected fixes/improvements relevant to Spark users:
* Safe cast fails from numpy float64 array with nans to integer, ARROW-4258
* Java, Reduce heap usage for variable width vectors, ARROW-4147
* Binary identity cast not implemented, ARROW-4101
* pyarrow open_stream deprecated, use ipc.open_stream, ARROW-4098
* conversion to date object no longer needed, ARROW-3910
* Error reading IPC file with no record batches, ARROW-3894
* Signed to unsigned integer cast yields incorrect results when type sizes are the same, ARROW-3790
* from_pandas gives incorrect results when converting floating point to bool, ARROW-3428
* Import pyarrow fails if scikit-learn is installed from conda (boost-cpp / libboost issue), ARROW-3048
* Java update to official Flatbuffers version 1.9.0, ARROW-3175
complete list [here](https://issues.apache.org/jira/issues/?jql=project%20%3D%20ARROW%20AND%20status%20in%20(Resolved%2C%20Closed)%20AND%20fixVersion%20%3D%200.12.0)
PySpark requires the following fixes to work with PyArrow 0.12.0
* Encrypted pyspark worker fails due to ChunkedStream missing closed property
* pyarrow now converts dates as objects by default, which causes error because type is assumed datetime64
* ArrowTests fails due to difference in raised error message
* pyarrow.open_stream deprecated
* tests fail because groupby adds index column with duplicate name
## How was this patch tested?
Ran unit tests with pyarrow versions 0.8.0, 0.10.0, 0.11.1, 0.12.0

This adds the entire memory used by spark’s executor (as measured by procfs) to the executor metrics. The memory usage is collected from the entire process tree under the executor. The metrics are subdivided into memory used by java, by python, and by other processes, to aid users in diagnosing the source of high memory usage.
The additional metrics are sent to the driver in heartbeats, using the mechanism introduced by SPARK-23429. This also slightly extends that approach to allow one ExecutorMetricType to collect multiple metrics.
Added unit tests and also tested on a live cluster.

…. Other related changes to get JDK 11 working, to test
## What changes were proposed in this pull request?
- Access `sun.misc.Cleaner` (Java 8) and `jdk.internal.ref.Cleaner` (JDK 9+) by reflection (note: the latter only works if illegal reflective access is allowed)
- Access `sun.misc.Unsafe.invokeCleaner` in Java 9+ instead of `sun.misc.Cleaner` (Java 8)
In order to test anything on JDK 11, I also fixed a few small things, which I include here:
- Fix minor JDK 11 compile issues
- Update scala plugin, Jetty for JDK 11, to facilitate tests too
This doesn't mean JDK 11 tests all pass now, but lots do. Note also that the JDK 9+ solution for the Cleaner has a big caveat.
## How was this patch tested?
Existing tests. Manually tested JDK 11 build and tests, and tests covering this change appear to pass. All Java 8 tests should still pass, but this change alone does not achieve full JDK 11 compatibility.

## What changes were proposed in this pull request?
This is the official first attempt to break huge single `tests.py` file - I did it locally before few times and gave up for some reasons. Now, currently it really makes the unittests super hard to read and difficult to check. To me, it even bothers me to to scroll down the big file. It's one single 7000 lines file!
This is not only readability issue. Since one big test takes most of tests time, the tests don't run in parallel fully - although it will costs to start and stop the context.
We could pick up one example and follow. Given my investigation, the current style looks closer to NumPy structure and looks easier to follow. Please see https://github.com/numpy/numpy/tree/master/numpy.
Basically this PR proposes to break down `pyspark/sql/tests.py` into ...:
```bash
pyspark

...
│ ├── tests # Includes all tests broken down from 'pyspark/sql/tests.py'
│ │ │ # Each matchs to module in 'pyspark/sql'. Additionally, some logical group can

## How was this patch tested?
Existing tests should cover.
`cd python` and `./run-tests-with-coverage`. Manually checked they are actually being ran.
Each test (not officially) can be ran via:
```
SPARK_TESTING=1 ./bin/pyspark pyspark.sql.tests.test_pandas_udf_scalar
```
Note that if you're using Mac and Python 3, you might have to `OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES`.

When running the release script, you will be interrupted unexpectedly
```
ATTENTION! Your password for authentication realm:

can only be stored to disk unencrypted! You are advised to configure
your system so that Subversion can store passwords encrypted, if
possible. See the documentation for details.
You can avoid future appearances of this warning by setting the value
of the 'store-plaintext-passwords' option to either 'yes' or 'no' in
'/home/spark-rm/.subversion/servers'.

## What changes were proposed in this pull request?
We vote for the artifacts. All releases are in the form of the source materials needed to make changes to the software being released. (http://www.apache.org/legal/release-policy.html#artifacts)
From Spark 2.4.0, the source artifact and binary artifact starts to contain own proper LICENSE files (LICENSE, LICENSE-binary). It's great to have them. However, unfortunately, `dev/make-distribution.sh` inside source artifacts start to fail because it expects `LICENSE-binary` and source artifact have only the LICENSE file.
https://dist.apache.org/repos/dist/dev/spark/v2.4.0-rc4-bin/spark-2.4.0.tgz
`dev/make-distribution.sh` is used during the voting phase because we are voting on that source artifact instead of GitHub repository. Individual contributors usually don't have the downstream repository and starts to try build the voting source artifacts to help the verification for the source artifact during voting phase. (Personally, I did before.)
This PR aims to recover that script to work in any way. This doesn't aim for source artifacts to reproduce the compiled artifacts.
## How was this patch tested?
Manual.
```
$ rm LICENSE-binary
$ dev/make-distribution.sh
```

We find below warnings when build spark project:
```
[warn] * com.google.code.findbugs:jsr305:3.0.0 is selected over 1.3.9
[warn] +- org.apache.hadoop:hadoop-common:2.7.3 (depends on 3.0.0)
[warn] +- org.apache.spark:spark-core_2.11:3.0.0-SNAPSHOT (depends on 1.3.9)
[warn] +- org.apache.spark:spark-network-common_2.11:3.0.0-SNAPSHOT (depends on 1.3.9)
[warn] +- org.apache.spark:spark-unsafe_2.11:3.0.0-SNAPSHOT (depends on 1.3.9)
```
So ideally we need to upgrade jsr305 from 1.3.9 to 3.0.0 to fix this warning
Upgrade one of the dependencies jsr305 version from 1.3.9 to 3.0.0

## What changes were proposed in this pull request?
Upgrade netty dependency from 4.1.17 to 4.1.30.
Explanation:
Currently when sending a ChunkedByteBuffer with more than 16 chunks over the network will trigger a "merge" of all the blocks into one big transient array that is then sent over the network. This is problematic as the total memory for all chunks can be high (2GB) and this would then trigger an allocation of 2GB to merge everything, which will create OOM errors.
And we can avoid this issue by upgrade the netty. https://github.com/netty/netty/pull/8038

Many companies have their own enterprise GitHub to manage Spark code. To build and test in those repositories with Jenkins need to modify this script.
