Latest Docker releases are stricter in their enforcement of build argument scope. The location of the `ARG spark_uid` declaration in the Python and R Dockerfiles means the variable is out of scope by the time it is used in a `USER` declaration resulting in a container running as root rather than the default/configured UID.
Also with some of the refactoring of the script that has happened since my PR that introduced the configurable UID it turns out the `-u <uid>` argument is not being properly passed to the Python and R image builds when those are opted into
## What changes were proposed in this pull request?
This commit moves the `ARG` declaration to just before the argument is used such that it is in scope. It also ensures that Python and R image builds receive the build arguments that include the `spark_uid` argument where relevant
## How was this patch tested?
Prior to the patch images are produced where the Python and R images ignore the default/configured UID:
```
> docker run -it --entrypoint /bin/bash rvesse/spark-py:uid456
bash-4.4# whoami
root
bash-4.4# id -u
0
bash-4.4# exit
> docker run -it --entrypoint /bin/bash rvesse/spark:uid456
bash-4.4$ id -u
456
bash-4.4$ exit
```
Note that the Python image is still running as `root` having ignored the configured UID of 456 while the base image has the correct UID because the relevant `ARG` declaration is correctly in scope.
After the patch the correct UID is observed:
```
> docker run -it --entrypoint /bin/bash rvesse/spark-r:uid456
bash-4.4$ id -u
456
bash-4.4$ exit
exit
> docker run -it --entrypoint /bin/bash rvesse/spark-py:uid456
bash-4.4$ id -u
456
bash-4.4$ exit
exit
> docker run -it --entrypoint /bin/bash rvesse/spark:uid456
bash-4.4$ id -u
456
bash-4.4$ exit
```

This enhancement allows for specifying the desired context to use for the initial K8S client auto-configuration. This allows users to more easily access alternative K8S contexts without having to first
explicitly change their current context via kubectl.
Explicitly set my K8S context to a context pointing to a non-existent cluster, then launched Spark jobs with explicitly specified contexts via the new `spark.kubernetes.context` configuration property.
Example Output:
```
> kubectl config current-context
minikube
> minikube status
minikube: Stopped
cluster:
kubectl:
> ./spark-submit --master k8s://https://localhost:6443 --deploy-mode cluster --name spark-pi --class org.apache.spark.examples.SparkPi --conf spark.executor.instances=2 --conf spark.kubernetes.context=docker-for-desktop --conf spark.kubernetes.container.image=rvesse/spark:debian local:///opt/spark/examples/jars/spark-examples_2.11-3.0.0-SNAPSHOT.jar 4

Currently there is code scattered in a bunch of places to do different
things related to HTTP security, such as access control, setting
security-related headers, and filtering out bad content. This makes it
really easy to miss these things when writing new UI code.
This change creates a new filter that does all of those things, and
makes sure that all servlet handlers that are attached to the UI get
the new filter and any user-defined filters consistently. The extent
of the actual features should be the same as before.
The new filter is added at the end of the filter chain, because authentication
is done by custom filters and thus needs to happen first. This means that
custom filters see unfiltered HTTP requests - which is actually the current
behavior anyway.
As a side-effect of some of the code refactoring, handlers added after
the initial set also get wrapped with a GzipHandler, which didn't happen
before.
Tested with added unit tests and in a history server with SPNEGO auth
configured.

This change modifies the behavior of the delegation token code when running
on YARN, so that the driver controls the renewal, in both client and cluster
mode. For that, a few different things were changed:
* The AM code only runs code that needs DTs when DTs are available.
In a way, this restores the AM behavior to what it was pre-SPARK-23361, but
keeping the fix added in that bug. Basically, all the AM code is run in a
"UGI.doAs()" block; but code that needs to talk to HDFS (basically the
distributed cache handling code) was delayed to the point where the driver
is up and running, and thus when valid delegation tokens are available.
* SparkSubmit / ApplicationMaster now handle user login, not the token manager.
The previous AM code was relying on the token manager to keep the user
logged in when keytabs are used. This required some odd APIs in the token
manager and the AM so that the right UGI was exposed and used in the right
places.
After this change, the logged in user is handled separately from the token
manager, so the API was cleaned up, and, as explained above, the whole AM
runs under the logged in user, which also helps with simplifying some more code.
* Distributed cache configs are sent separately to the AM.
Because of the delayed initialization of the cached resources in the AM, it
became easier to write the cache config to a separate properties file instead
of bundling it with the rest of the Spark config. This also avoids having
to modify the SparkConf to hide things from the UI.
* Finally, the AM doesn't manage the token manager anymore.
The above changes allow the token manager to be completely handled by the
driver's scheduler backend code also in YARN mode (whether client or cluster),
making it similar to other RMs. To maintain the fix added in SPARK-23361 also
in client mode, the AM now sends an extra message to the driver on initialization
to fetch delegation tokens; and although it might not really be needed, the
driver also keeps the running AM updated when new tokens are created.
Tested in a kerberized cluster with the same tests used to validate SPARK-23361,
in both client and cluster mode. Also tested with a non-kerberized cluster.

Recently, the ability to expose the metrics for YARN Shuffle Service was added as part of [SPARK-18364](https://github.com/apache/spark/pull/22485). We need to add some metrics to be able to determine the number of active connections as well as open connections to the external shuffle service to benchmark network and connection issues on large cluster environments.
Added two more shuffle server metrics for Spark Yarn shuffle service: numRegisteredConnections which indicate the number of registered connections to the shuffle service and numActiveConnections which indicate the number of active connections to the shuffle service at any given point in time.
If these metrics are outputted to a file, we get something like this:

This change hooks up the k8s backed to the updated HadoopDelegationTokenManager,
so that delegation tokens are also available in client mode, and keytab-based token
renewal is enabled.
The change re-works the k8s feature steps related to kerberos so
that the driver does all the credential management and provides all
the needed information to executors - so nothing needs to be added
to executor pods. This also makes cluster mode behave a lot more
similarly to client mode, since no driver-related config steps are run
in the latter case.
The main two things that don't need to happen in executors anymore are:
- adding the Hadoop config to the executor pods: this is not needed
since the Spark driver will serialize the Hadoop config and send
it to executors when running tasks.
- mounting the kerberos config file in the executor pods: this is
not needed once you remove the above. The Hadoop conf sent by
the driver with the tasks is already resolved (i.e. has all the
kerberos names properly defined), so executors do not need access
to the kerberos realm information anymore.
The change also avoids creating delegation tokens unnecessarily.
This means that they'll only be created if a secret with tokens
was not provided, and if a keytab is not provided. In either of
those cases, the driver code will handle delegation tokens: in
cluster mode by creating a secret and stashing them, in client
mode by using existing mechanisms to send DTs to executors.
One last feature: the change also allows defining a keytab with
a "local:" URI. This is supported in client mode (although that's
the same as not saying "local:"), and in k8s cluster mode. This
allows the keytab to be mounted onto the image from a pre-existing
secret, for example.
Finally, the new code always sets SPARK_USER in the driver and
executor pods. This is in line with how other resource managers
behave: the submitting user reflects which user will access
Hadoop services in the app. (With kerberos, that's overridden
by the logged in user.) That user is unrelated to the OS user
the app is running as inside the containers.
Tested:
- client and cluster mode with kinit
- cluster mode with keytab
- cluster mode with local: keytab
- YARN cluster with keytab (to make sure it isn't broken)

3) Go to Yarn application list UI link
4) Launch the application master for the Spark-SQL app ID and access all the tabs by appending tab name.
5) It will display an error for all tabs including SQL tab.(before able to access SQL tab,as Authentication filter is not applied for SQL tab)
6) Also can be verified with info logs,that Authentication filter applied to SQL tab.(before it is not applied).

YARN applicationMaster metrics registration introduced in SPARK-24594 causes further registration of static metrics (Codegenerator and HiveExternalCatalog) and of JVM metrics, which I believe do not belong in this context.
This looks like an unintended side effect of using the start method of [[MetricsSystem]].
A possible solution proposed here, is to introduce startNoRegisterSources to avoid these additional registrations of static sources and of JVM sources in the case of YARN applicationMaster metrics (this could be useful for other metrics that may be added in the future).

This change makes the driver and executor builders a lot simpler
by encapsulating almost all feature logic into the respective
feature classes. The only logic that remains is the creation of
the initial pod, which needs to happen before anything else so
is better to be left in the builder class.
Most feature classes already behave fine when the config has nothing
they should handle, but a few minor tweaks had to be added. Unit
tests were also updated or added to account for these.
The builder suites were simplified a lot and just test the remaining
pod-related code in the builders themselves.

This change modifies the logic in the SecurityManager to do two
things:
- generate unique app secrets also when k8s is being used
- only store the secret in the user's UGI on YARN
The latter is needed so that k8s won't unnecessarily create
k8s secrets for the UGI credentials when only the auth token
is stored there.
On the k8s side, the secret is propagated to executors using
an environment variable instead. This ensures it works in both
client and cluster mode.
Security doc was updated to mention the feature and clarify that
proper access control in k8s should be enabled for it to be secure.

## What changes were proposed in this pull request?
Keeps K8s executor resources present if case of failure or normal termination.
Introduces a new boolean config option: `spark.kubernetes.deleteExecutors`, with default value set to true.
The idea is to update Spark K8s backend structures but leave the resources around.
The assumption is that since entries are not removed from the `removedExecutorsCache` we are immune to updates that refer to the the executor resources previously removed.
The only delete operation not touched is the one in the `doKillExecutors` method.
Reason is right now we dont support [blacklisting](https://issues.apache.org/jira/browse/SPARK-23485) and dynamic allocation with Spark on K8s. In both cases in the future we might want to handle these scenarios although its more complicated.
More tests can be added if approach is approved.

There are a few issues with the current configuration types used in
the kubernetes backend:
- they use type parameters for role-specific specialization, which makes
type signatures really noisy throughout the code base.
- they break encapsulation by forcing the code that creates the config
object to remove the configuration from SparkConf before creating the
k8s-specific wrapper.
- they don't provide an easy way for tests to have default values for
fields they do not use.
This change fixes those problems by:
- creating a base config type with role-specific specialization using
inheritance
- encapsulating the logic of parsing SparkConf into k8s-specific views
inside the k8s config classes
- providing some helper code for tests to easily override just the part
of the configs they want.
Most of the change relates to the above, especially cleaning up the
tests. While doing that, I also made some smaller changes elsewhere:
- removed unnecessary type parameters in KubernetesVolumeSpec
- simplified the error detection logic in KubernetesVolumeUtils; all
the call sites would just throw the first exception collected by
that class, since they all called "get" on the "Try" object. Now
the unnecessary wrapping is gone and the exception is just thrown
where it occurs.
- removed a lot of unnecessary mocking from tests.
- changed the kerberos-related code so that less logic needs to live
in the driver builder. In spirit it should be part of the upcoming
work in this series of cleanups, but it made parts of this change
simpler.
Tested with existing unit tests and integration tests.

Closes#22959 from vanzin/SPARK-25876.
Adds USER directives to the Dockerfiles which is configurable via build argument (`spark_uid`) for easy customisation. A `-u` flag is added to `bin/docker-image-tool.sh` to make it easy to customise this e.g.
```
> bin/docker-image-tool.sh -r rvesse -t uid -u 185 build
> bin/docker-image-tool.sh -r rvesse -t uid push
```
If no UID is explicitly specified it defaults to `185` - this is per skonto's suggestion to align with the OpenShift standard reserved UID for Java apps (
https://lists.openshift.redhat.com/openshift-archives/users/2016-March/msg00283.html)
Notes:
- We have to make the `WORKDIR` writable by the root group or otherwise jobs will fail with `AccessDeniedException`
To Do:
- [x] Debug and resolve issue with client mode test
- [x] Consider whether to always propagate `SPARK_USER_NAME` to environment of driver and executor pods so `entrypoint.sh` can insert that into `/etc/passwd` entry
- [x] Rebase once PR #23013 is merged and update documentation accordingly
Built the Docker images with the new Dockerfiles that include the `USER` directives. Ran the Spark on K8S integration tests against the new images. All pass except client mode which I am currently debugging further.
Also manually dropped myself into the resulting container images via `docker run` and checked `id -u` output to see that UID is as expected.
Tried customising the UID from the default via the new `-u` argument to `docker-image-tool.sh` and again checked the resulting image for the correct runtime UID.

The "build context" for a docker image - basically the whole contents of the
current directory where "docker" is invoked - can be huge in a dev build,
easily breaking a couple of gigs.
Doing that copy 3 times during the build of docker images severely slows
down the process.
This patch creates a smaller build context - basically mimicking what the
make-distribution.sh script does, so that when building the docker images,
only the necessary bits are in the current directory. For PySpark and R that
is optimized further, since those images are built based on the previously
built Spark main image.
In my current local clone, the dir size is about 2G, but with this script
the "context" sent to docker is about 250M for the main image, 1M for the
pyspark image and 8M for the R image. That speeds up the image builds
considerably.
I also snuck in a fix to the k8s integration test dependencies in the sbt
build, so that the examples are properly built (without having to do it
manually).

The build has a lot of deprecation warnings. Some are new in Scala 2.12 and Java 11. We've fixed some, but I wanted to take a pass at fixing lots of easy miscellaneous ones here.
They're too numerous and small to list here; see the pull request. Some highlights:
- `BeanInfo` is deprecated in 2.12, and BeanInfo classes are pretty ancient in Java. Instead, case classes can explicitly declare getters
- Eta expansion of zero-arg methods; foo() becomes () => foo() in many cases
- Floating-point Range is inexact and deprecated, like 0.0 to 100.0 by 1.0
- finalize() is finally deprecated (just needs to be suppressed)
- StageInfo.attempId was deprecated and easiest to remove here
I'm not now going to touch some chunks of deprecation warnings:
- Parquet deprecations
- Hive deprecations (particularly serde2 classes)
- Deprecations in generated code (mostly Thriftserver CLI)

This PR makes Spark's default Scala version as 2.12, and Scala 2.11 will be the alternative version. This implies that Scala 2.12 will be used by our CI builds including pull request builds.
We'll update the Jenkins to include a new compile-only jobs for Scala 2.11 to ensure the code can be still compiled with Scala 2.11.

The integration tests can now be run in sbt if the right profile
is enabled, using the "test" task under the respective project.
This avoids having to fall back to maven to run the tests, which
invalidates all your compiled stuff when you go back to sbt, making
development way slower than it should.
There's also a task to run the tests directly without refreshing
the docker images, which is helpful if you just made a change to
the submission code which should not affect the code in the images.
The sbt tasks currently are not very customizable; there's some
very minor things you can set in the sbt shell itself, but otherwise
it's hardcoded to run on minikube.
I also had to make some slight adjustments to the IT code itself,
mostly to remove assumptions about the existing harness.
Tested on sbt and maven.

Right now there are 3 different classes dealing with building the driver
command to run inside the pod, one for each "binding" supported by Spark.
This has two main shortcomings:
- the code in the 3 classes is very similar; changing things in one place
would probably mean making a similar change in the others.
- it gives the false impression that the step implementation is the only
place where binding-specific logic is needed. That is not true; there
was code in KubernetesConf that was binding-specific, and there's also
code in the executor-specific config step. So the 3 classes weren't really
working as a language-specific abstraction.
On top of that, the current code was propagating command line parameters in
a different way depending on the binding. That doesn't seem necessary, and
in fact using environment variables for command line parameters is in general
a really bad idea, since you can't handle special characters (e.g. spaces)
that way.
This change merges the 3 different code paths for Java, Python and R into
a single step, and also merges the 3 code paths to start the Spark driver
in the k8s entry point script. This increases the amount of shared code,
and also moves more feature logic into the step itself, so it doesn't live
in KubernetesConf.
Note that not all logic related to setting up the driver lives in that
step. For example, the memory overhead calculation still lives separately,
except it now happens in the driver config step instead of outside the
step hierarchy altogether.
Some of the noise in the diff is because of changes to KubernetesConf, which
will be addressed in a separate change.
Tested with new and updated unit tests + integration tests.

Closes#22897 from vanzin/SPARK-25875.
## What changes were proposed in this pull request?
Currently K8S integration tests are hardcoded to use a `minikube` based backend. `minikube` is VM based so can be resource hungry and also doesn't cope well with certain networking setups (for example using Cisco AnyConnect software VPN `minikube` is unusable as it detects its own IP incorrectly).
This PR Adds a new K8S integration testing backend that allows for using the Kubernetes support in [Docker for Desktop](https://blog.docker.com/2018/07/kubernetes-is-now-available-in-docker-desktop-stable-channel/). It also generalises the framework to be able to run the integration tests against an arbitrary Kubernetes cluster.
To Do:
- [x] General Kubernetes cluster backend
- [x] Documentation on Kubernetes integration testing
- [x] Testing of general K8S backend
- [x] Check whether change from timestamps being `Time` to `String` in Fabric 8 upgrade needs additional fix up

Closes#22805 from rvesse/SPARK-25809.
This avoids having two classes to deal with tokens; now the above
class is a one-stop shop for dealing with delegation tokens. The
YARN backend extends that class instead of doing composition like
before, resulting in a bit less code there too.
The renewer functionality is basically the same code that used to
be in YARN's AMCredentialRenewer. That is also the reason why the
public API of HadoopDelegationTokenManager is a little bit odd;
the YARN AM has some odd requirements for how this all should be
initialized, and the weirdness is needed currently to support that.
Tested:
- YARN with stress app for DT renewal
- Mesos and K8S with basic kerberos tests (both tgt and keytab)

`removeExecutorFromSpark` tries to fetch the reason the executor exited from Kubernetes, which may be useful if the pod was OOMKilled. However, the code previously deleted the pod from Kubernetes first which made retrieving this status impossible. This fixes the ordering.
On a separate but related note, it would be nice to wait some time before removing the pod - to let the operator examine logs and such.

The test fix is to allocate a `Resource` object only after the resource
types have been initialized. Otherwise the YARN classes get in a weird
state and throw a different exception than expected, because the resource
has a different view of the registered resources.
I also removed a test for a null resource since that seems unnecessary
and made the fix more complicated.
All the other changes are just cleanup; basically simplify the tests by
defining what is being tested and deriving the resource type registration
and the SparkConf from that data, instead of having redundant definitions
in the tests.
Ran tests with Hadoop 3 (and also without it).

## What changes were proposed in this pull request?
This PR adds CLI support for YARN custom resources, e.g. GPUs and any other resources YARN defines.
The custom resources are defined with Spark properties, no additional CLI arguments were introduced.
The properties can be defined in the following form:
**AM resources, client mode:**
Format: `spark.yarn.am.resource.<resource-name>`
The property name follows the naming convention of YARN AM cores / memory properties: `spark.yarn.am.memory and spark.yarn.am.cores
`
**Driver resources, cluster mode:**
Format: `spark.yarn.driver.resource.<resource-name>`
The property name follows the naming convention of driver cores / memory properties: `spark.driver.memory and spark.driver.cores.`
**Executor resources:**
Format: `spark.yarn.executor.resource.<resource-name>`
The property name follows the naming convention of executor cores / memory properties: `spark.executor.memory / spark.executor.cores`.
For the driver resources (cluster mode) and executor resources properties, we use the `yarn` prefix here as custom resource types are specific to YARN, currently.
**Validation:**
Please note that a validation logic is added to avoid having requested resources defined in 2 ways, for example defining the following configs:
```
"--conf", "spark.driver.memory=2G",
"--conf", "spark.yarn.driver.resource.memory=1G"
```
will not start execution and will print an error message.
## How was this patch tested?
Unit tests + manual execution with Hadoop2 and Hadoop 3 builds.
Testing have been performed on a real cluster with Spark and YARN configured:
Cluster and client mode
Request Resource Types with lowercase and uppercase units
Start Spark job with only requesting standard resources (mem / cpu)
Error handling cases:
- Request unknown resource type
- Request Resource type (either memory / cpu) with duplicate configs at the same time (e.g. with this config:
```
--conf spark.yarn.am.resource.memory=1G \
--conf spark.yarn.driver.resource.memory=2G \
--conf spark.yarn.executor.resource.memory=3G \
```
), ResourceTypeValidator handles these cases well, so it is not permitted
- Request standard resource (memory / cpu) with the new style configs, e.g. --conf spark.yarn.am.resource.memory=1G, this is not permitted and handled well.
An example about how I ran the testcases:
```
cd ~;export HADOOP_CONF_DIR=/opt/hadoop/etc/hadoop/;
./spark-2.4.0-SNAPSHOT-bin-custom-spark/bin/spark-submit \
--class org.apache.spark.examples.SparkPi \
--master yarn \
--deploy-mode cluster \
--driver-memory 1G \
--driver-cores 1 \
--executor-memory 1G \
--executor-cores 1 \
--conf spark.logConf=true \
--conf spark.yarn.executor.resource.gpu=3G \
--verbose \

This PR excludes the cases above for SQL code path for external calls like table name, column name and etc.
For test suites, or when it's clear there's no locale problem like Turkish locale problem, it uses `Locale.ROOT`.

Heartbeat shouldn't include accumulators for zero metrics.
Heartbeats sent from executors to the driver every 10 seconds contain metrics and are generally on the order of a few KBs. However, for large jobs with lots of tasks, heartbeats can be on the order of tens of MBs, causing tasks to die with heartbeat failures. We can mitigate this by not sending zero metrics to the driver.

Fixes the collision issue with spark executor names in client mode, see SPARK-25295 for the details.
It follows the cluster name convention as app-name will be used as the prefix and if that is not defined we use "spark" as the default prefix. Eg. `spark-pi-1536781360723-exec-1` where spark-pi is the name of the app passed at the config side or transformed if it contains illegal characters.
Also fixes the issue with spark app name having spaces in cluster mode.
If you run the Spark Pi test in client mode it passes.
The tricky part is the user may set the app name:
3030b82c89/examples/src/main/scala/org/apache/spark/examples/SparkPi.scala (L30)
If i do:
```
./bin/spark-submit
...
--deploy-mode cluster --name "spark pi"
...
```
it will fail as the app name is used for the prefix of driver's pod name and it cannot have spaces (according to k8s conventions).

## What changes were proposed in this pull request?
The default behaviour of Spark on K8S currently is to create `emptyDir` volumes to back `SPARK_LOCAL_DIRS`. In some environments e.g. diskless compute nodes this may actually hurt performance because these are backed by the Kubelet's node storage which on a diskless node will typically be some remote network storage.
Even if this is enterprise grade storage connected via a high speed interconnect the way Spark uses these directories as scratch space (lots of relatively small short lived files) has been observed to cause serious performance degradation. Therefore we would like to provide the option to use K8S's ability to instead back these `emptyDir` volumes with `tmpfs`. Therefore this PR adds a configuration option that enables `SPARK_LOCAL_DIRS` to be backed by Memory backed `emptyDir` volumes rather than the default.
Documentation is added to describe both the default behaviour plus this new option and its implications. One of which is that scratch space then counts towards your pods memory limits and therefore users will need to adjust their memory requests accordingly.
*NB* - This is an alternative version of PR #22256 reduced to just the `tmpfs` piece
## How was this patch tested?

The configuration parameter "spark.shuffle.service.enabled" has defined in `package.scala`, and it is also used in many place, so we can replace it with `SHUFFLE_SERVICE_ENABLED`.
and unified this configuration parameter "spark.shuffle.service.port" together.

This adds `spark.executor.pyspark.memory` to configure Python's address space limit, [`resource.RLIMIT_AS`](https://docs.python.org/3/library/resource.html#resource.RLIMIT_AS). Limiting Python's address space allows Python to participate in memory management. In practice, we see fewer cases of Python taking too much memory because it doesn't know to run garbage collection. This results in YARN killing fewer containers. This also improves error messages so users know that Python is consuming too much memory:
```
File "build/bdist.linux-x86_64/egg/package/library.py", line 265, in fe_engineer
fe_eval_rec.update(f(src_rec_prep, mat_rec_prep))
File "build/bdist.linux-x86_64/egg/package/library.py", line 163, in fe_comp
comparisons = EvaluationUtils.leven_list_compare(src_rec_prep.get(item, []), mat_rec_prep.get(item, []))
File "build/bdist.linux-x86_64/egg/package/evaluationutils.py", line 25, in leven_list_compare
permutations = sorted(permutations, reverse=True)
MemoryError
```
The new pyspark memory setting is used to increase requested YARN container memory, instead of sharing overhead memory between python and off-heap JVM activity.
## How was this patch tested?
Tested memory limits in our YARN cluster and verified that MemoryError is thrown.

YARN `AmIpFilter` adds a new parameter "RM_HA_URLS" to support RM HA, but Spark on YARN doesn't provide a such parameter, so it will be failed to redirect when running on RM HA. The detailed exception can be checked from JIRA. So here fixing this issue by adding "RM_HA_URLS" parameter.

Our HDFS cluster configured 5 nameservices: `nameservices1`, `nameservices2`, `nameservices3`, `nameservices-dev1` and `nameservices4`, but `nameservices-dev1` unstable. So sometimes an error occurred and causing the entire job failed since [SPARK-24149](https://issues.apache.org/jira/browse/SPARK-24149):
I think it's best to add a switch here.

## What changes were proposed in this pull request?
When using older versions of spark releases, a use case generated a huge code-gen file which hit the limitation `Constant pool has grown past JVM limit of 0xFFFF`. In this situation, it should fail immediately. But the diagnosis message sent to RM is too large, the ApplicationMaster suspended and RM's ZKStateStore was crashed. For 2.3 or later spark releases the limitation of code-gen has been removed, but maybe there are still some uncaught exceptions that contain oversized error message will cause such a problem.
This PR is aim to cut down the diagnosis message size.

**## What changes were proposed in this pull request?**
When the yarn.nodemanager.resource.memory-mb or yarn.scheduler.maximum-allocation-mb
memory assignment is insufficient, Spark always reports an error request to adjust
yarn.scheduler.maximum-allocation-mb even though in message it shows the memory value
of yarn.nodemanager.resource.memory-mb parameter,As the error Message is bit misleading to the user we can modify the same, We can keep the error message same as executor memory validation message.
Defintion of **yarn.nodemanager.resource.memory-mb:**
Amount of physical memory, in MB, that can be allocated for containers. It means the amount of memory YARN can utilize on this node and therefore this property should be lower then the total memory of that machine.
**yarn.scheduler.maximum-allocation-mb:**
It defines the maximum memory allocation available for a container in MB
it means RM can only allocate memory to containers in increments of "yarn.scheduler.minimum-allocation-mb" and not exceed "yarn.scheduler.maximum-allocation-mb" and It should not be more than total allocated memory of the Node.

We shall check whether the barrier stage requires more slots (to be able to launch all tasks in the barrier stage together) than the total number of active slots currently, and fail fast if trying to submit a barrier stage that requires more slots than current total number.
This PR proposes to add a new method `getNumSlots()` to try to get the total number of currently active slots in `SchedulerBackend`, support of this new method has been added to all the first-class scheduler backends except `MesosFineGrainedSchedulerBackend`.
## How was this patch tested?

## What changes were proposed in this pull request?
(a) disabled rest submission server by default in standalone mode
(b) fails the standalone master if rest server enabled & authentication secret set
(c) fails the mesos cluster dispatcher if authentication secret set
(d) doc updates
(e) when submitting a standalone app, only try the rest submission first if spark.master.rest.enabled=true
otherwise you'd see a 10 second pause like
18/08/09 08:13:22 INFO RestSubmissionClient: Submitting a request to launch an application in spark://...
18/08/09 08:13:33 WARN RestSubmissionClient: Unable to connect to server spark://...
I also made sure the mesos cluster dispatcher failed with the secret enabled, though I had to do that on slightly different code as I don't have mesos native libs around.
## How was this patch tested?
I ran the tests in the mesos module & in core for org.apache.spark.deploy.*
I ran a test on a cluster with standalone master to make sure I could still start with the right configs, and would fail the right way too.

Closes#21900 from mccheah/fix-integration-test-service-account.
## What changes were proposed in this pull request?
Propose new APIs and modify job/task scheduling to support barrier execution mode, which requires all tasks in a same barrier stage start at the same time, and retry all tasks in case some tasks fail in the middle. The barrier execution mode is useful for some ML/DL workloads.
The proposed API changes include:
- `RDDBarrier` that marks an RDD as barrier (Spark must launch all the tasks together for the current stage).
- `BarrierTaskContext` that support global sync of all tasks in a barrier stage, and provide extra `BarrierTaskInfo`s.
In DAGScheduler, we retry all tasks of a barrier stage in case some tasks fail in the middle, this is achieved by unregistering map outputs for a shuffleId (for ShuffleMapStage) or clear the finished partitions in an active job (for ResultStage).
## How was this patch tested?
Add `RDDBarrierSuite` to ensure we convert RDDs correctly;
Add new test cases in `DAGSchedulerSuite` to ensure we do task scheduling correctly;
Add new test cases in `SparkContextSuite` to ensure the barrier execution mode actually works (both under local mode and local cluster mode).
Add new test cases in `TaskSchedulerImplSuite` to ensure we schedule tasks for barrier taskSet together.

Closes#21874 from mccheah/enable-client-mode-test.
## What changes were proposed in this pull request?
Support client mode for the Kubernetes scheduler.
Client mode works more or less identically to cluster mode. However, in client mode, the Spark Context needs to be manually bootstrapped with certain properties which would have otherwise been set up by spark-submit in cluster mode. Specifically:
- If the user doesn't provide a driver pod name, we don't add an owner reference. This is for usage when the driver is not running in a pod in the cluster. In such a case, the driver can only provide a best effort to clean up the executors when the driver exits, but cleaning up the resources is not guaranteed. The executor JVMs should exit if the driver JVM exits, but the pods will still remain in the cluster in a COMPLETED or FAILED state.
- The user must provide a host (spark.driver.host) and port (spark.driver.port) that the executors can connect to. When using spark-submit in cluster mode, spark-submit generates the headless service automatically; in client mode, the user is responsible for setting up their own connectivity.
We also change the authentication configuration prefixes for client mode.
## How was this patch tested?
Adding an integration test to exercise client mode support.

Closes#21748 from mccheah/k8s-client-mode.
## What changes were proposed in this pull request?
In this PR metrics are introduced for YARN. As up to now there was no metrics in the YARN module a new metric system is created with the name "applicationMaster".
To support both client and cluster mode the metric system lifecycle is bound to the AM.
## How was this patch tested?
Both client and cluster mode was tested manually.
Before the test on one of the YARN node spark-core was removed to cause the allocation failure.
Spark was started as (in case of client mode):
```
spark2-submit \
--class org.apache.spark.examples.SparkPi \
--conf "spark.yarn.blacklist.executor.launch.blacklisting.enabled=true" --conf "spark.blacklist.application.maxFailedExecutorsPerNode=2" --conf "spark.dynamicAllocation.enabled=true" --conf "spark.metrics.conf.*.sink.console.class=org.apache.spark.metrics.sink.ConsoleSink" \
--master yarn \
--deploy-mode client \
original-spark-examples_2.11-2.4.0-SNAPSHOT.jar \
1000
```
In both cases the YARN logs contained the new metrics as:
```
$ yarn logs --applicationId application_1529926424933_0015
...

…rEnv properly
Running in yarn cluster mode and trying to set pythonpath via spark.yarn.appMasterEnv.PYTHONPATH doesn't work.
the yarn Client code looks at the env variables:
val pythonPathStr = (sys.env.get("PYTHONPATH") ++ pythonPath)
But when you set spark.yarn.appMasterEnv it puts it into the local env.
So the python path set in spark.yarn.appMasterEnv isn't properly set.
You can work around if you are running in cluster mode by setting it on the client like:
PYTHONPATH=./addon/python/ spark-submit
## What changes were proposed in this pull request?
In Client.scala, PYTHONPATH was being overridden, so changed code to append values to PYTHONPATH instead of overriding them.
## How was this patch tested?
Added log statements to ApplicationMaster.scala to check for environment variable PYTHONPATH, ran a spark job in cluster mode before the change and verified the issue. Performed the same test after the change and verified the fix.

This PR enables a Java bytecode check tool [spotbugs](https://spotbugs.github.io/) to avoid possible integer overflow at multiplication. When an violation is detected, the build process is stopped.
Due to the tool limitation, some other checks will be enabled. In this PR, [these patterns](http://spotbugs-in-kengo-toda.readthedocs.io/en/lqc-list-detectors/detectors.html#findpuzzlers) in `FindPuzzlers` can be detected.
This check is enabled at `compile` phase. Thus, `mvn compile` or `mvn package` launches this check.

Closes#21542 from kiszk/SPARK-24529.
This PR continues #21095 and intersects with #21238. I've added volume mounts as a separate step and added PersistantVolumeClaim support.
There is a fundamental problem with how we pass the options through spark conf to fabric8. For each volume type and all possible volume options we would have to implement some custom code to map config values to fabric8 calls. This will result in big body of code we would have to support and means that Spark will always be somehow out of sync with k8s.
I think there needs to be a discussion on how to proceed correctly (eg use PodPreset instead)
----
Due to the complications of provisioning and managing actual resources this PR addresses only volume mounting of already present resources.
