### What changes were proposed in this pull request?
Two different versions are used for the same artifacts, `exec-maven-plugin` and `scalatest-maven-plugin`. This PR aims to use the same versions for `exec-maven-plugin` and `scalatest-maven-plugin`. In addition, this PR removes `scala-maven-plugin.version` from `K8s` integration suite because it's unused.
### Why are the changes needed?
This will prevent the mistake which upgrades only one place and forgets the others.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Pass the Jenkins K8S IT.

### What is changed?
This pull request adds the ability to migrate shuffle files during Spark's decommissioning. The design document associated with this change is at https://docs.google.com/document/d/1xVO1b6KAwdUhjEJBolVPl9C6sLj7oOveErwDSYdT-pE .
To allow this change the `MapOutputTracker` has been extended to allow the location of shuffle files to be updated with `updateMapOutput`. When a shuffle block is put, a block update message will be sent which triggers the `updateMapOutput`.
Instead of rejecting remote puts of shuffle blocks `BlockManager` delegates the storage of shuffle blocks to it's shufflemanager's resolver (if supported). A new, experimental, trait is added for shuffle resolvers to indicate they handle remote putting of blocks.
The existing block migration code is moved out into a separate file, and a producer/consumer model is introduced for migrating shuffle files from the host as quickly as possible while not overwhelming other executors.
### Why are the changes needed?
Recomputting shuffle blocks can be expensive, we should take advantage of our decommissioning time to migrate these blocks.
### Does this PR introduce any user-facing change?
This PR introduces two new configs parameters, `spark.storage.decommission.shuffleBlocks.enabled` & `spark.storage.decommission.rddBlocks.enabled` that control which blocks should be migrated during storage decommissioning.
### How was this patch tested?
New unit test & expansion of the Spark on K8s decom test to assert that decommisioning with shuffle block migration means that the results are not recomputed even when the original executor is terminated.
This PR is a cleaned-up version of the previous WIP PR I made https://github.com/apache/spark/pull/28331 (thanks to attilapiros for his very helpful reviewing on it :)).

### What changes were proposed in this pull request?
This PR aims to drop Python 2.7, 3.4 and 3.5.
Roughly speaking, it removes all the widely known Python 2 compatibility workarounds such as `sys.version` comparison, `__future__`. Also, it removes the Python 2 dedicated codes such as `ArrayConstructor` in Spark.
### Why are the changes needed?
1. Unsupport EOL Python versions
2. Reduce maintenance overhead and remove a bit of legacy codes and hacks for Python 2.
3. PyPy2 has a critical bug that causes a flaky test, SPARK-28358 given my testing and investigation.
4. Users can use Python type hints with Pandas UDFs without thinking about Python version
5. Users can leverage one latest cloudpickle, https://github.com/apache/spark/pull/28950. With Python 3.8+ it can also leverage C pickle.
### Does this PR introduce _any_ user-facing change?
Yes, users cannot use Python 2.7, 3.4 and 3.5 in the upcoming Spark version.
### How was this patch tested?
Manually tested and also tested in Jenkins.

### What changes were proposed in this pull request?
This PR aims to activate `hadoop-2.7` profile by default in Kubernetes IT module.
### Why are the changes needed?
While SPARK-31881 added Hadoop 3.2 support, one default test dependency was moved to `hadoop-2.7` profile. It works when we give one of `hadoop-2.7` and `hadoop-3.2`, but it fails when we don't give any profile.

### What changes were proposed in this pull request?
This PR aims to upgrade `kubernetes-client` library to bring the JDK8 related fixes. Please note that JDK11 works fine without any problem.
- https://github.com/fabric8io/kubernetes-client/releases/tag/v4.9.2
- JDK8 always uses http/1.1 protocol (Prevent OkHttp from wrongly enabling http/2)
### Why are the changes needed?
OkHttp "wrongly" detects the Platform as Jdk9Platform on JDK 8u251.

- https://stackoverflow.com/questions/61565751/why-am-i-not-able-to-run-sparkpi-example-on-a-kubernetes-k8s-cluster
Although there is a workaround `export HTTP2_DISABLE=true` and `Downgrade JDK or K8s`, we had better avoid this problematic situation.
### Does this PR introduce _any_ user-facing change?
No. This will recover the failures on JDK 8u252.

### Why are the changes needed?
minikube 1.8.0 ~ 1.8.2 generate a cluster with a nodename `m01` while all the other versions have `minikube`. This causes `PVTestSuite` failure.

```
Also, the image size is unnecessarily big (almost `1GB`) and growing while `minio` is `55.8MB` with the same features.
```

This PR is based on an existing/previou PR - https://github.com/apache/spark/pull/19045
### What changes were proposed in this pull request?
This changes adds a decommissioning state that we can enter when the cloud provider/scheduler lets us know we aren't going to be removed immediately but instead will be removed soon. This concept fits nicely in K8s and also with spot-instances on AWS / preemptible instances all of which we can get a notice that our host is going away. For now we simply stop scheduling jobs, in the future we could perform some kind of migration of data during scale-down, or at least stop accepting new blocks to cache.
There is a design document at https://docs.google.com/document/d/1xVO1b6KAwdUhjEJBolVPl9C6sLj7oOveErwDSYdT-pE/edit?usp=sharing
### Why are the changes needed?
With more move to preemptible multi-tenancy, serverless environments, and spot-instances better handling of node scale down is required.
### Does this PR introduce any user-facing change?
There is no API change, however an additional configuration flag is added to enable/disable this behaviour.
### How was this patch tested?
New integration tests in the Spark K8s integration testing. Extension of the AppClientSuite to test decommissioning seperate from the K8s.

### What changes were proposed in this pull request?
This PR aims to support JDK11 test in K8S integration tests.
- This is an update in testing framework instead of individual tests.
- This will enable JDK11 runtime test when you didn't installed JDK11 on your local system.
### Why are the changes needed?
Apache Spark 3.0.0 adds JDK11 support, but K8s integration tests use JDK8 until now.
### Does this PR introduce any user-facing change?
No. This is a dev-only test-related PR.
### How was this patch tested?
This is irrelevant to Jenkins UT, but Jenkins K8S IT (JDK8) should pass.

This basically does what BasicDriverFeatureStep already does to achieve the
same thing in cluster mode; but since that class (or any other feature) is
not invoked in client mode, it needs to be done elsewhere.
I also modified the client mode integration test to check the executor name
prefix; while there I had to fix the minikube backend to parse the output
from newer minikube versions (I have 1.5.2).

### Does this PR introduce any user-facing change?
Nope, it should be transparent to users
### How was this patch tested?
This patch was tested manually using a simple pyspark job
```python
from pyspark.sql import SparkSession
if __name__ == '__main__':
spark = SparkSession.builder.getOrCreate()
```
The expected behaviour of this "job" is that both python's and jvm's process exit automatically after the main runs. This is the case for spark versions <= 2.4. On version 2.4.3, the jvm process hangs because there's a non daemon thread running
```
"OkHttp WebSocket https://10.96.0.1/..." #121 prio=5 os_prio=0 tid=0x00007fb27c005800 nid=0x24b waiting on condition [0x00007fb300847000]

```
This is caused by a bug on `kubernetes-client` library, which is fixed on the version that we are upgrading to.
When the mentioned job is run with this patch applied, the behaviour from spark <= 2.4.3 is restored and both processes terminate successfully

This patch tries to keep consistency whenever UTF-8 charset is needed, as using `StandardCharsets.UTF_8` instead of using "UTF-8". If the String type is needed, `StandardCharsets.UTF_8.name()` is used.
This change also brings the benefit of getting rid of `UnsupportedEncodingException`, as we're providing `Charset` instead of `String` whenever possible.
This also changes some private Catalyst helper methods to operate on encodings as `Charset` objects rather than strings.

## What changes were proposed in this pull request?
This PR aims to recover our K8s integration test suite by extending node affinity in order to pass `PVTestsSuite` in `DockerForDesktop` environment, too. Previously, `PVTestsSuite` fails at `--deploy-mode docker-for-desktop` option because the node affinity requires `minibase` node.
For `Docker Desktop`, there are two node names like the following. Note that Spark testing needs K8s v1.13 and above. So, this PR should be verified with `Docker Desktop (Edge)` version. This PR adds both because next stable `Docker Desktop` will have K8s v1.14.3.
**Docker Desktop (Stable, K8s v1.10.11)**
```
$ kubectl get node
NAME STATUS ROLES AGE VERSION
docker-for-desktop Ready master 52s v1.10.11
```
**Docker Desktop 2.1.0.0 (Edge, K8s v1.14.3, Released 2019-07-26)**
```
$ kubectl get node
NAME STATUS ROLES AGE VERSION
docker-desktop Ready master 16h v1.14.3
```
## How was this patch tested?
Pass the Jenkins K8s integration test (`minibase`) and install `Docker Desktop 2.1.0.0 (Edge)` and run the integration test in `DockerForDesktop`. Note that this fixes only `PVTestsSuite`.

Change the format of the build command in the README to start with a `./` prefix

## What changes were proposed in this pull request?
Fixes the service account inconsistency that breaks pull secrets. It gives the option to the user to setup a specific service account for the executors if he has to
(via `spark.kubernetes.authenticate.executor.serviceAccountName`). Defaults to the driver's one.
We are not supporting special authentication credentials for the executors with this PR.
## How was this patch tested?
Tested manually by launching a Spark job exercising the introduced settings.
Added a new integration tests for this fix.

## What changes were proposed in this pull request?
- solves the current issue with --packages in cluster mode (there is no ticket for it). Also note of some [issues](https://issues.apache.org/jira/browse/SPARK-22657) of the past here when hadoop libs are used at the spark submit side.
- supports spark.jars, spark.files, app jar.
It works as follows:
Spark submit uploads the deps to the HCFS. Then the driver serves the deps via the Spark file server.
No hcfs uris are propagated.
The related design document is [here](https://docs.google.com/document/d/1peg_qVhLaAl4weo5C51jQicPwLclApBsdR1To2fgc48/edit). the next option to add is the RSS but has to be improved given the discussion in the past about it (Spark 2.3).
## How was this patch tested?
- Run integration test suite.
- Run an example using S3:
```
./bin/spark-submit \

```
Added integration tests based on [Ceph nano](https://github.com/ceph/cn). Looks very [active](http://www.sebastien-han.fr/blog/2019/02/24/Ceph-nano-is-getting-better-and-better/).
Unfortunately minio needs hadoop >= 2.8.

## What changes were proposed in this pull request?
This replaces use of collection classes like `MutableList` and `ArrayStack` with workalikes that are available in 2.12, as they will be removed in 2.13. It also removes use of `.to[Collection]` as its uses was superfluous anyway. Removing `collection.breakOut` will have to wait until 2.13

## What changes were proposed in this pull request?
Fixed the `spark-<version>-yarn-shuffle.jar` artifact packaging to shade the native netty libraries:
- shade the `META-INF/native/libnetty_*` native libraries when packagin
the yarn shuffle service jar. This is required as netty library loader
derives that based on shaded package name.
- updated the `org/spark_project` shade package prefix to `org/sparkproject`
(i.e. removed underscore) as the former breaks the netty native lib loading.
This was causing the yarn external shuffle service to fail
when spark.shuffle.io.mode=EPOLL
