In the PR, I propose new CSV option `emptyValue` and an update in the SQL Migration Guide which describes how to revert previous behavior when empty strings were not written at all. Since Spark 2.4, empty strings are saved as `""` to distinguish them from saved `null`s.

## 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?
Ran with this option in our diskless compute environments to verify functionality

As described in [SPARK-25261](https://issues.apache.org/jira/projects/SPARK/issues/SPARK-25261),the unit of spark.executor.memory and spark.driver.memory is parsed as bytes in some cases if no unit specified, while in https://spark.apache.org/docs/latest/configuration.html#application-properties, they are descibed as MiB, which may lead to some misunderstandings.

After SPARK-18371, it is guaranteed that there would be at least one message per partition per batch using direct kafka API when new messages exist in the topics. This change will give the user the option of setting the minimum instead of just a hard coded 1 limit
The related unit test is updated and some internal tests verified that the topic partitions with new messages will be progressed by the specified minimum.

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.

(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.

## What changes were proposed in this pull request?
Currently the set operations INTERSECT, UNION and EXCEPT are assigned the same precedence. This PR fixes the problem by giving INTERSECT higher precedence than UNION and EXCEPT. UNION and EXCEPT operators are evaluated in the order in which they appear in the query from left to right.
This results in change in behavior because of the change in order of evaluations of set operators in a query. The old behavior is still preserved under a newly added config parameter.
Query `:`
```
SELECT * FROM t1
UNION
SELECT * FROM t2
EXCEPT
SELECT * FROM t3
INTERSECT
SELECT * FROM t4
```
Parsed plan before the change `:`

## 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.
Fetch-to-mem is guaranteed to fail if the message is bigger than 2 GB,
so we might as well use fetch-to-disk in that case. The message includes
some metadata in addition to the block data itself (in particular
UploadBlock has a lot of metadata), so we leave a little room.

In hive its displayed as "UNKNOWN" which makes more sense than displaying wrong date. seems to be a limitation as of now even from hive, better we can follow the hive behavior unless the limitation has been resolved from hive.

## 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
...
-- Gauges ----------------------------------------------------------------------

This commit adds the `cascadeTruncate` option to the JDBC datasource
API, for databases that support this functionality (PostgreSQL and
Oracle at the moment). This allows for applying a cascading truncate
that affects tables that have foreign key constraints on the table
being truncated.
## What changes were proposed in this pull request?
Add `cascadeTruncate` option to JDBC datasource API. Allow this to affect the
`TRUNCATE` query for databases that support this option.
## How was this patch tested?
Existing tests for `truncateQuery` were updated. Also, an additional test was added
to ensure that the correct syntax was applied, and that enabling the config for databases
that do not support this option does not result in invalid queries.

## What changes were proposed in this pull request?
The example wants to create a dense matrix ((1.0, 2.0), (3.0, 4.0), (5.0, 6.0)), but the list is given as [1, 2, 3, 4, 5, 6]. Now it is changed as [1, 3, 5, 2, 4, 6].
And the example wants to create an RDD of coordinate entries like:
entries = sc.parallelize([(0, 0, 1.2), (1, 0, 2.1), (2, 1, 3.7)]).
However, it is done with the MatrixEntry class like:
entries = sc.parallelize([MatrixEntry(0, 0, 1.2), MatrixEntry(1, 0, 2.1), MatrixEntry(6, 1, 3.7)]),
where the third MatrixEntry has a different row index.
Now it is changed as MatrixEntry(2, 1, 3.7).

Closes#21778 from HyukjinKwon/SPARK-20220.
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.

In the case of getting tokens via customized `ServiceCredentialProvider`, it is required that `ServiceCredentialProvider` be available in local spark-submit process classpath. In this case, all the configured remote sources should be forced to download to local.
