### What changes were proposed in this pull request?
This change is to allow custom resource scheduler (GPUs,FPGAs,etc) resource discovery to be more flexible. Users are asking for it to work with hadoop 2.x versions that do not support resource scheduling in YARN and/or also they may not run in an isolated environment.
This change creates a plugin api that users can write their own resource discovery class that allows a lot more flexibility. The user can chain plugins for different resource types. The user specified plugins execute in the order specified and will fall back to use the discovery script plugin if they don't return information for a particular resource.
I had to open up a few of the classes to be public and change them to not be case classes and make them developer api in order for the the plugin to get enough information it needs.
I also relaxed the yarn side so that if yarn isn't configured for resource scheduling we just warn and go on. This helps users that have yarn 3.1 but haven't configured the resource scheduling side on their cluster yet, or aren't running in isolated environment.
The user would configured this like:
--conf spark.resources.discovery.plugin="org.apache.spark.resource.ResourceDiscoveryFPGAPlugin, org.apache.spark.resource.ResourceDiscoveryGPUPlugin"
Note the executor side had to be wrapped with a classloader to make sure we include the user classpath for jars they specified on submission.
Note this is more flexible because the discovery script has limitations such as spawning it in a separate process. This means if you are trying to allocate resources in that process they might be released when the script returns. Other things are the class makes it more flexible to be able to integrate with existing systems and solutions for assigning resources.
### Why are the changes needed?
to more easily use spark resource scheduling with older versions of hadoop or in non-isolated enivronments.
### Does this PR introduce any user-facing change?
Yes a plugin api
### How was this patch tested?
Unit tests added and manual testing done on yarn and standalone modes.

### What changes were proposed in this pull request?
This is the second PR for the Stage Level Scheduling. This is adding in the necessary executor side changes:
1) executors to know what ResourceProfile they should be using
2) handle parsing the resource profile settings - these are not in the global configs
3) then reporting back to the driver what resource profile it was started with.
This PR adds all the piping for YARN to pass the information all the way to executors, but it just uses the default ResourceProfile (which is the global applicatino level configs).
At a high level these changes include:
1) adding a new --resourceProfileId option to the CoarseGrainedExecutorBackend
2) Add the ResourceProfile settings to new internal confs that gets passed into the Executor
3) Executor changes that use the resource profile id passed in to read the corresponding ResourceProfile confs and then parse those requests and discover resources as necessary
4) Executor registers to Driver with the Resource profile id so that the ExecutorMonitor can track how many executor with each profile are running
5) YARN side changes to show that passing the resource profile id and confs actually works. Just uses the DefaultResourceProfile for now.
I also removed a check from the CoarseGrainedExecutorBackend that used to check to make sure there were task requirements before parsing any custom resource executor requests. With the resource profiles this becomes much more expensive because we would then have to pass the task requests to each executor and the check was just a short cut and not really needed. It was much cleaner just to remove it.
Note there were some changes to the ResourceProfile, ExecutorResourceRequests, and TaskResourceRequests in this PR as well because I discovered some issues with things not being immutable. That api now look like:
val rpBuilder = new ResourceProfileBuilder()
val ereq = new ExecutorResourceRequests()
val treq = new TaskResourceRequests()
ereq.cores(2).memory("6g").memoryOverhead("2g").pysparkMemory("2g").resource("gpu", 2, "/home/tgraves/getGpus")
treq.cpus(2).resource("gpu", 2)
val resourceProfile = rpBuilder.require(ereq).require(treq).build
This makes is so that ResourceProfile is immutable and Spark can use it directly without worrying about the user changing it.
### Why are the changes needed?
These changes are needed for the executor to report which ResourceProfile they are using so that ultimately the dynamic allocation manager can use that information to know how many with a profile are running and how many more it needs to request. Its also needed to get the resource profile confs to the executor so that it can run the appropriate discovery script if needed.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
Unit tests and manually on YARN.

The issue here is that when Spark is downscaling the application and deletes
a few pod requests that aren't needed anymore, it may actually race with the
K8S scheduler, who may be bringing up those executors. So they may have enough
time to connect back to the driver, register, to just be deleted soon after.
This wastes resources and causes misleading entries in the driver log.
The change (ab)uses the blacklisting mechanism to consider the deleted excess
pods as blacklisted, so that if they try to connect back, the driver will deny
it.
It also changes the executor registration slightly, since even with the above
change there were misleading logs. That was because the executor registration
message was an RPC that always succeeded (bar network issues), so the executor
would always try to send an unregistration message to the driver, which would
then log several messages about not knowing anything about the executor. The
change makes the registration RPC succeed or fail directly, instead of using
the separate failure message that would lead to this issue.
Note the last change required some changes in a standalone test suite related
to dynamic allocation, since it relied on the driver not throwing exceptions
when a duplicate executor registration happened.
Tested with existing unit tests, and with live cluster with dyn alloc on.

Remove `executorsPendingToRemove.clear()` from `CoarseGrainedSchedulerBackend.reset()`.
### Why are the changes needed?
Clear `executorsPendingToRemove` before remove executors will cause all tasks running on those "pending to remove" executors to count failures. But that's not true for the case of `executorsPendingToRemove(execId)=true`.
Besides, `executorsPendingToRemove` will be cleaned up within `removeExecutor()` at the end just as same as `executorsPendingLossReason`.

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

```
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

### What changes were proposed in this pull request?
The current docker image used by Kubernetes is `openjdk:8-alpine`. It was not supported and was removed with the commit 3eb0351b20 (diff-f95ffa3d1377774732c33f7b8368e099).
This PR proposes to move to a supported docker image.
### Why are the changes needed?
I think there are at least two reasons:
1. According to the commit, Alpine/musl is not officially supported by the OpenJDK project.
2. As no more OpenJDK 8 Alpine images, new JDK updates including security fixes
, are not applied to it. See below:
```
docker run -it --rm openjdk:8-alpine java -version
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (IcedTea 3.12.0) (Alpine 8.212.04-r0)
OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode)
```
```
docker run -it --rm openjdk:8-jdk-slim java -version

### What changes were proposed in this pull request?
In kubernetes, there are some naming regular expression requirements and restrictions on environment variable names, such as:
- In kubernetes version release-1.7 and earlier, the naming rules of pod environment variable names should meet the requirements of regular expressions: [[A-Za-z_] [A-Za-z0-9_]*](https://github.com/kubernetes/kubernetes/blob/release-1.7/staging/src/k8s.io/apimachinery/pkg/util/validation/validation.go#L169)
- In kubernetes version release-1.8 and later, the naming rules of pod environment variable names should meet the requirements of regular expressions: [[-. _ A-ZA-Z][-. _ A-ZA-Z0-9].*](https://github.com/kubernetes/kubernetes/blob/release-1.8/staging/src/k8s.io/apimachinery/pkg/util/validation/validation.go#L305)
However, in spark on k8s mode, spark should add restrictions on environmental variable names when creating executorEnv.
In addition, we need to use regular expressions adapted to the high version of k8s to increase the restrictions on the names of environmental variables.
Otherwise, the pod will not be created properly and the spark application will be suspended.
To solve the problem above, a regular validation to executorEnv is added and committed.
### Why are the changes needed?
If no validation rules are added, the environment variable names that don't meet the requirements will cause the pod to not be created properly and the application will be suspended.

### Why are the changes needed?
It will avoid about a thousand compiler warnings when we start to support Scala 2.13. I wanted to make the change in 3.0 as there are less likely to be back-ports from 3.0 to 2.4 than 3.1 to 3.0, for example, minimizing that downside to touching so many files.
Unfortunately, that makes this quite a big change.

### What changes were proposed in this pull request?
Make r file extension check case insensitive for spark-submit.
### Why are the changes needed?
spark-submit does not accept `.r` files as R scripts. Some codebases have r files that end with lowercase file extensions. It is inconvenient to use spark-submit with lowercase extension R files. The error is not very clear (https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmitArguments.scala#L232).
```
$ ./bin/spark-submit examples/src/main/r/dataframe.r
Exception in thread "main" org.apache.spark.SparkException: Cannot load main class from JAR file:/Users/dongjoon/APACHE/spark-release/spark-2.4.4-bin-hadoop2.7/examples/src/main/r/dataframe.r
```
### Does this PR introduce any user-facing change?
Yes. spark-submit can now be used to run R scripts with `.r` file extension.
### How was this patch tested?
Manual.

### What changes were proposed in this pull request?
- Remove SQLContext.createExternalTable and Catalog.createExternalTable, deprecated in favor of createTable since 2.2.0, plus tests of deprecated methods
- Remove HiveContext, deprecated in 2.0.0, in favor of `SparkSession.builder.enableHiveSupport`
- Remove deprecated KinesisUtils.createStream methods, plus tests of deprecated methods, deprecate in 2.2.0
- Remove deprecated MLlib (not Spark ML) linear method support, mostly utility constructors and 'train' methods, and associated docs. This includes methods in LinearRegression, LogisticRegression, Lasso, RidgeRegression. These have been deprecated since 2.0.0
- Remove deprecated Pyspark MLlib linear method support, including LogisticRegressionWithSGD, LinearRegressionWithSGD, LassoWithSGD
- Remove 'runs' argument in KMeans.train() method, which has been a no-op since 2.0.0
- Remove deprecated ChiSqSelector isSorted protected method
- Remove deprecated 'yarn-cluster' and 'yarn-client' master argument in favor of 'yarn' and deploy mode 'cluster', etc
Notes:
- I was not able to remove deprecated DataFrameReader.json(RDD) in favor of DataFrameReader.json(Dataset); the former was deprecated in 2.2.0, but, it is still needed to support Pyspark's .json() method, which can't use a Dataset.
- Looks like SQLContext.createExternalTable was not actually deprecated in Pyspark, but, almost certainly was meant to be? Catalog.createExternalTable was.
- I afterwards noted that the toDegrees, toRadians functions were almost removed fully in SPARK-25908, but Felix suggested keeping just the R version as they hadn't been technically deprecated. I'd like to revisit that. Do we really want the inconsistency? I'm not against reverting it again, but then that implies leaving SQLContext.createExternalTable just in Pyspark too, which seems weird.
- I *kept* LogisticRegressionWithSGD, LinearRegressionWithSGD, LassoWithSGD, RidgeRegressionWithSGD in Pyspark, though deprecated, as it is hard to remove them (still used by StreamingLogisticRegressionWithSGD?) and they are not fully removed in Scala. Maybe should not have been deprecated.
### Why are the changes needed?
Deprecated items are easiest to remove in a major release, so we should do so as much as possible for Spark 3. This does not target items deprecated 'recently' as of Spark 2.3, which is still 18 months old.
### Does this PR introduce any user-facing change?
Yes, in that deprecated items are removed from some public APIs.
### How was this patch tested?
Existing tests.

### What changes were proposed in this pull request?
Resolves [SPARK-28778: Shuffle jobs fail due to incorrect advertised address when running in a virtual network on Mesos](https://issues.apache.org/jira/browse/SPARK-28778).
This patch fixes a bug which occurs when shuffle jobs are launched by Mesos in a virtual network. Mesos scheduler sets executor `--hostname` parameter to `0.0.0.0` in the case when `spark.mesos.network.name` is provided. This makes executors use `0.0.0.0` as their advertised address and, in the presence of shuffle, executors fail to fetch shuffle blocks from each other using `0.0.0.0` as the origin. When a virtual network is used the hostname or IP address is not known upfront and assigned to a container at its start time so the executor process needs to advertise the correct dynamically assigned address to be reachable by other executors.
Changes:
- added a fallback to `Utils.localHostName()` in Spark Executors when `--hostname` is not provided
- removed setting executor address to `0.0.0.0` from Mesos scheduler
- refactored the code related to building executor command in Mesos scheduler
- added network configuration support to Docker containerizer
- added unit tests
### Why are the changes needed?
The bug described above prevents Mesos users from running any jobs which involve shuffle due to the inability of executors to fetch shuffle blocks because of incorrect advertised address when virtual network is used.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
- added unit test to `MesosCoarseGrainedSchedulerBackendSuite` which verifies the absence of `--hostname` parameter when `spark.mesos.network.name` is provided and its presence otherwise
- added unit test to `MesosSchedulerBackendUtilSuite` which verifies that `MesosSchedulerBackendUtil.buildContainerInfo` sets network-related properties for Docker containerizer
- unit tests from this repo launched with profiles: `./build/mvn test -Pmesos -Pnetlib-lgpl -Psparkr -Phive -Phive-thriftserver`, build log attached: [mvn.test.log](https://github.com/apache/spark/files/3516891/mvn.test.log)
- integration tests from [DCOS Spark repo](https://github.com/mesosphere/spark-build), more specifically - [test_spark_cni.py](https://github.com/mesosphere/spark-build/blob/master/tests/test_spark_cni.py) which runs a specific [shuffle job](https://github.com/mesosphere/spark-build/blob/master/tests/jobs/scala/src/main/scala/ShuffleApp.scala) and verifies its successful completion, Mesos task network configuration, and IP addresses for both Mesos and Docker containerizers

This change makes the client mode AM ignore any login configuration,
which is now always handled by the driver. The previous code tried
to achieve that by modifying the configuration visible to the AM, but
that missed the case where old configuration names were being used.
