Liang-Chi Hsieh ea8b5df474 [SPARK-28938][K8S] Move to supported OpenJDK docker image for Kubernetes
### 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
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (build 1.8.0_222-b10)
OpenJDK 64-Bit Server VM (build 25.222-b10, mixed mode)
```

### Does this PR introduce any user-facing change?

Yes. This changes the base docker image of Spark.

### How was this patch tested?

Existing tests.

Closes #26037 from viirya/SPARK-28938.

maruilei 77510c602a [SPARK-29233][K8S] Add regex expression checks for executorEnv…
### 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.

### Does this PR introduce any user-facing change?

No.

### How was this patch tested?

Add unit tests and manually run.

Sean Owen e1ea806b30 [SPARK-29291][CORE][SQL][STREAMING][MLLIB] Change procedure-like declaration to function + Unit for 2.13
### What changes were proposed in this pull request?

Scala 2.13 emits a deprecation warning for procedure-like declarations:

```
def foo() {
 ...
```

This is equivalent to the following, so should be changed to avoid a warning:

```
def foo(): Unit = {
  ...
```

### 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.

### Does this PR introduce any user-facing change?

No behavior change at all.

### How was this patch tested?

Existing tests.

### 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

### Does this PR introduce any user-facing change?

Yes. spark-submit can now be used to run R scripts with `.r` file extension.

Sean Owen 6378d4bc06 [SPARK-28980][CORE][SQL][STREAMING][MLLIB] Remove most items deprecated in Spark 2.2.0 or earlier, for Spark 3
### 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.

Closes #25684 from srowen/SPARK-28980.

Anton Kirillov f17f1d01e2 [SPARK-28778][MESOS] Fixed executors advertised address when running in virtual network
### 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

Dongjoon Hyun f7c9de9035 [SPARK-28765][BUILD] Add explict exclusions to avoid JDK11 dependency issue
### What changes were proposed in this pull request?

This PR adds explicit exclusions to avoid Maven `JDK11` dependency issues.

### Why are the changes needed?

Maven/Ivy seems to be confused during dependency generation on `JDK11` environment.
This is not only wrong, but also causes a Jenkins failure during dependency manifest check on `JDK11` environment.

**JDK8**
```

```

### Does this PR introduce any user-facing change?

No.

### How was this patch tested?

Do the following in both `JDK8` and `JDK11` environment. The dependency manifest should not be changed. In the current `master` branch, `JDK11` changes the dependency manifest.
```

Marcelo Vanzin 0343854f54 [SPARK-28487][K8S] More responsive dynamic allocation with K8S
This change implements a few changes to the k8s pod allocator so
that it behaves a little better when dynamic allocation is on.

(i) Allow the application to ramp up immediately when there's a
change in the target number of executors. Without this change,
scaling would only trigger when a change happened in the state of
the cluster, e.g. an executor going down, or when the periodical
snapshot was taken (default every 30s).

(ii) Get rid of pending pod requests, both acknowledged (i.e. Spark
knows that a pod is pending resource allocation) and unacknowledged
(i.e. Spark has requested the pod but the API server hasn't created it
yet), when they're not needed anymore. This avoids starting those
executors to just remove them after the idle timeout, wasting resources
in the meantime.

(iii) Re-work some of the code to avoid unnecessary logging. While not
bad without dynamic allocation, the existing logging was very chatty
when dynamic allocation was on. With the changes, all the useful
information is still there, but only when interesting changes happen.

(iv) Gracefully shut down executors when they become idle. Just deleting
the pod causes a lot of ugly logs to show up, so it's better to ask pods

pods" option when dynamic allocation is on.

Liang-Chi Hsieh 37eedf6149 [SPARK-28652][TESTS][K8S] Add python version check for executor
## What changes were proposed in this pull request?

Current two PySpark version tests in PythonTestsSuite, just test against Python version at driver side. Because the test script doesn't run any spark job requiring python worker, it doesn't actually do version check at worker side. This patch adds pieces of code to the test script, to run a simple job to verify Python version.

## How was this patch tested?

Unit test. Locally manual test.

Jungtaek Lim (HeartSaVioR) 128ea37bda [SPARK-28601][CORE][SQL] Use StandardCharsets.UTF_8 instead of "UTF-8" string representation, and get rid of UnsupportedEncodingException
## What changes were proposed in this pull request?

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.

## How was this patch tested?

Existing unit tests.

Yuanjian Li db39f45baf [SPARK-28593][CORE] Rename ShuffleClient to BlockStoreClient which more close to its usage
## What changes were proposed in this pull request?

After SPARK-27677, the shuffle client not only handles the shuffle block but also responsible for local persist RDD blocks. For better code scalability and precise semantics(as the [discussion](https://github.com/apache/spark/pull/24892#discussion_r300173331)), here we did several changes:

- Rename ShuffleClient to BlockStoreClient.
- Correspondingly rename the ExternalShuffleClient to ExternalBlockStoreClient, also change the server-side class from ExternalShuffleBlockHandler to ExternalBlockHandler.
- Move MesosExternalBlockStoreClient to Mesos package.

Note, we still keep the name of BlockTransferService, because the `Service` contains both client and server, also the name of BlockTransferService is not referencing shuffle client only.

## How was this patch tested?

Existing UT.

HyukjinKwon 946aef0535 [SPARK-28550][K8S][TESTS] Unset SPARK_HOME environment variable in K8S integration preparation
## What changes were proposed in this pull request?

Currently, if we run the Kubernetes integration tests with `SPARK_HOME` already set, it refers the `SPARK_HOME` even when `--spark-tgz` is specified.

This PR proposes to unset `SPARK_HOME` to let the docker-image-tool script detect `SPARK_HOME`. Otherwise, it cannot indicate the unpacked directory as its home.

```bash

In KubernetesExecutorBuilder.scala, the LocalDrisFeatureStep is built before MountVolumesFeatureStep which means we cannot use any volumes mount later.

Dongjoon Hyun 767802500c [SPARK-28534][K8S][TEST] Update node affinity for DockerForDesktop backend in PVTestsSuite
## 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`.

```
$ dev/make-distribution.sh --pip --tgz -Phadoop-2.7 -Pkubernetes

Thomas Graves 43d68cd4ff [SPARK-27959][YARN] Change YARN resource configs to use .amount
## What changes were proposed in this pull request?

we are adding in generic resource support into spark where we have suffix for the amount of the resource so that we could support other configs.

Spark on yarn already had added configs to request resources via the configs spark.yarn.{executor/driver/am}.resource=<some amount>, where the <some amount> is value and unit together.  We should change those configs to have a `.amount` suffix on them to match the spark configs and to allow future configs to be more easily added. YARN itself already supports tags and attributes so if we want the user to be able to pass those from spark at some point having a suffix makes sense. it would allow for a spark.yarn.{executor/driver/am}.resource.{resource}.tag= type config.

## What changes were proposed in this pull request?

Change the resource config spark.{executor/driver}.resource.{resourceName}.count to .amount to allow future usage of containing both a count and a unit.  Right now we only support counts - # of gpus for instance, but in the future we may want to support units for things like memory - 25G. I think making the user only have to specify a single config .amount is better then making them specify 2 separate configs of a .count and then a .unit.  Change it now since its a user facing config.

Amount also matches how the spark on yarn configs are setup.

Add ability to map the spark resource configs spark.{executor/driver}.resource.{resourceName} to kubernetes Container builder so that we request resources (gpu,s/fpgas/etc) from kubernetes.

I added a generic vendor config which is only used by kubernetes right now.  I intentionally didn't put it into the kubernetes config namespace just to avoid adding more config prefixes.

## 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).

- Run integration test suite.
- Run an example using S3:

Thomas Graves db2e3c4341 [SPARK-27024] Executor interface for cluster managers to support GPU and other resources
## What changes were proposed in this pull request?

Add in GPU and generic resource type allocation to the executors.

Note this is part of a bigger feature for gpu-aware scheduling and is just how the executor find the resources. The general flow :

   - users ask for a certain set of resources, for instance number of gpus - each cluster manager has a specific way to do this.
  -  cluster manager allocates a container or set of resources (standalone mode)
-    When spark launches the executor in that container, the executor either has to be told what resources it has or it has to auto discover them.
  -  Executor has to register with Driver and tell the driver the set of resources it has so the scheduler can use that to schedule tasks that requires a certain amount of each of those resources

In this pr I added configs and arguments to the executor to be able discover resources. The argument to the executor is intended to be used by standalone mode or other cluster managers that don't have isolation so that it can assign specific resources to specific executors in case there are multiple executors on a node. The argument is a file contains JSON Array of ResourceInformation objects.

The discovery script is meant to be used in an isolated environment where the executor only sees the resources it should use.

Note that there will be follow on PRs to add other parts like the scheduler part. See the epic high level jira: https://issues.apache.org/jira/browse/SPARK-24615

## How was this patch tested?

Added unit tests and manually tested.

Sam Tran bcd3b61c4b [SPARK-27347][MESOS] Fix supervised driver retry logic for outdated tasks
## What changes were proposed in this pull request?

This patch fixes a bug where `--supervised` Spark jobs would retry multiple times whenever an agent would crash, come back, and re-register even when those jobs had already relaunched on a different agent.

That is:
```
- supervised driver is running on agent1
- agent1 crashes
- driver is relaunched on another agent as `<task-id>-retry-1`
- agent1 comes back online and re-registers with scheduler
- spark relaunches the same job as `<task-id>-retry-2`
- now there are two jobs running simultaneously
```

This is because when an agent would come back and re-register it would send a status update `TASK_FAILED` for its old driver-task. Previous logic would indiscriminately remove the `submissionId` from Zookeeper's `launchedDrivers` node and add it to `retryList` node. Then, when a new offer came in, it would relaunch another `-retry-`  task even though one was previously running.

For example logs, scroll to bottom

## How was this patch tested?

- Added a unit test to simulate behavior described above
- Tested manually on a DC/OS cluster by
  ```
  - launching a --supervised spark job
  - dcos node ssh <to the agent with the running spark-driver>
  - systemctl stop dcos-mesos-slave
  - docker kill <driver-container-id>
  - [ wait until spark job is relaunched ]
  - systemctl start dcos-mesos-slave
  - [ observe spark driver is not relaunched as `-retry-2` ]
  ```

Log snippets included below. Notice the `-retry-1` task is running when status update for the old task comes in afterward:

jiafu.zhang@intel.com fa5dc0a45a [SPARK-26632][CORE] Separate Thread Configurations of Driver and Executor
## What changes were proposed in this pull request?

For the below three thread configuration items applied to both driver and executor,
spark.rpc.io.serverThreads
spark.rpc.io.clientThreads
spark.rpc.netty.dispatcher.numThreads,
we separate them to driver specifics and executor specifics.
spark.driver.rpc.io.serverThreads                     < - > spark.executor.rpc.io.serverThreads
spark.driver.rpc.io.clientThreads                      < - > spark.executor.rpc.io.clientThreads
spark.driver.rpc.netty.dispatcher.numThreads < - > spark.executor.rpc.netty.dispatcher.numThreads

Spark reads these specifics first and fall back to the common configurations.

## How was this patch tested?
We ran the SimpleMap app without shuffle for benchmark purpose to test Spark's scalability in HPC with omini-path NIC which has higher bandwidth than normal ethernet NIC.

Spark's base version is 2.4.0.
Spark ran in the Standalone mode. Driver was in a standalone node.
After the separation, the performance is improved a lot in 256 nodes and 512 nodes. see below test results of SimpleMapTask before and after the enhancement. You can view the tables in the  [JIRA](https://issues.apache.org/jira/browse/SPARK-26632) too.

ds: spark.driver.rpc.io.serverThreads
dc: spark.driver.rpc.io.clientThreads
dd: spark.driver.rpc.netty.dispatcher.numThreads
ed: spark.executor.rpc.netty.dispatcher.numThreads
time: Overall Time (s)
old time: Overall Time without Separation (s)

**Before:**

 nodes | ds | dc | dd | ed | time
-- |-- | -- | -- | -- | --
128 nodes | 8 | 8 | 8 | 8 | 108
256 nodes | 8 | 8 | 8 | 8 | 196
512 nodes | 8 | 8 | 8 | 8 | 377

**After:**

nodes | ds | dc | dd | ed | time | improvement
-- | -- | -- | -- | -- | -- | --
128 nodes | 15 | 15 | 10 | 30 | 107 | 0.9%
256 nodes | 12 | 15 | 10 | 30 | 159 | 18.8%

Adi Muraru 8ef4da753d [SPARK-27610][YARN] Shade netty native libraries
## 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

Rob Vesse b1c6b60ce7 [SPARK-26729][K8S] Fix typo with default value for R image name
## What changes were proposed in this pull request?

As discovered by users making use of this feature, there is a bug in the
declaration of the `R_IMAGE_NAME` variable that causes the default name to
not be properly set to `spark-r` but rather to just `-r`

## How was this patch tested?

Verified that the image name for the R image is now appropriately populated in the integration test script via Bash debug output.

NB - The fact that this wasn't spotted earlier highlights the fact that currently the K8S integration test suite does not have any tests for the R image as if it had this would have failed integration testing in the original PR #23846

LantaoJin 52838e74af [SPARK-13704][CORE][YARN] Reduce rack resolution time
## What changes were proposed in this pull request?

When you submit a stage on a large cluster, rack resolving takes a long time when initializing TaskSetManager because a script is invoked to resolve the rack of each host, one by one.
Based on current implementation, it takes 30~40 seconds to resolve the racks in our 5000 nodes' cluster. After applied the patch, it decreased to less than 15 seconds.

YARN-9332 has added an interface to handle multiple hosts in one invocation to save time. But before upgrading to the newest Hadoop, we could construct the same tool in Spark to resolve this issue.

## How was this patch tested?

UT and manually testing on a 5000 node cluster.

Rob Vesse 61d99462a0 [SPARK-26729][K8S] Make image names under test configurable
## What changes were proposed in this pull request?

Allow specifying system properties to customise the image names for the images used in the integration testing.  Useful if your CI/CD pipeline or policy requires using a different naming format.

This is one part of addressing SPARK-26729, I plan to have a follow up patch that will also make the names configurable when using `docker-image-tool.sh`

## How was this patch tested?

Ran integration tests against custom images generated by our CI/CD pipeline that do not follow Spark's existing hardcoded naming conventions using the new system properties to override the image names appropriately:

To avoid the case where the YARN libraries would swallow the exception and

As a safeguard, also explicitly stop the executor launch thread pool when

after the application started its shutdown.

## What changes were proposed in this pull request?

while performing some tests on our existing minikube and k8s infrastructure, i noticed that the integration tests were failing. i dug in and discovered the following message buried at the end of the stacktrace:

```
  Caused by: java.io.FileNotFoundException: /usr/lib/libnss3.so

after i added the `nss` package to `resource-managers/kubernetes/docker/src/main/dockerfiles/spark/Dockerfile`, everything worked.

this is also impacting current builds.  see:  https://amplab.cs.berkeley.edu/jenkins/job/testing-k8s-prb-make-spark-distribution-unified/8959/console

Ajith c324e1da9d [SPARK-27122][CORE] Jetty classes must not be return via getters in org.apache.spark.ui.WebUI
## What changes were proposed in this pull request?

When we run YarnSchedulerBackendSuite, the class path seems to be made from the classes folder(resource-managers/yarn/target/scala-2.12/classes) instead of jar (resource-managers/yarn/target/spark-yarn_2.12-3.0.0-SNAPSHOT.jar) . ui.getHandlers is in spark-core and its loaded from spark-core.jar which is shaded and hence refers to org.spark_project.jetty.servlet.ServletContextHandler

Here in  org.apache.spark.scheduler.cluster.YarnSchedulerBackend, as its not shaded, it expects org.eclipse.jetty.servlet.ServletContextHandler
Refer discussion  https://issues.apache.org/jira/browse/SPARK-27122?focusedCommentId=16792318&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16792318

Hence as a fix, org.apache.spark.ui.WebUI must only return a wrapper class instance or references so that Jetty classes can be avoided in getters which are accessed outside spark-core

Luca Canali f13ea15d79 [SPARK-26995][K8S] Make ld-linux-x86-64.so.2 visible to snappy native library under /lib in docker image with Alpine Linux
Running Spark in Docker image with Alpine Linux 3.9.0 throws errors when using snappy.

The issue can be reproduced for example as follows: `Seq(1,2).toDF("id").write.format("parquet").save("DELETEME1")`
The key part of the error stack is as follows `SparkException: Task failed while writing rows. .... Caused by: java.lang.UnsatisfiedLinkError: /tmp/snappy-1.1.7-2b4872f1-7c41-4b84-bda1-dbcb8dd0ce4c-libsnappyjava.so: Error loading shared library ld-linux-x86-64.so.2: Noded by /tmp/snappy-1.1.7-2b4872f1-7c41-4b84-bda1-dbcb8dd0ce4c-libsnappyjava.so)`

The source of the error appears to be that libsnappyjava.so needs ld-linux-x86-64.so.2 and looks for it in /lib, while in Alpine Linux 3.9.0 with libc6-compat version 1.1.20-r3 ld-linux-x86-64.so.2 is located in /lib64.
Note: this issue is not present with Alpine Linux 3.8 and libc6-compat version 1.1.19-r10

## What changes were proposed in this pull request?

A possible workaround proposed with this PR is to modify the Dockerfile by adding a symbolic link between /lib and /lib64 so that linux-x86-64.so.2 can be found in /lib. This is probably not the cleanest solution, but I have observed that this is what happened/happens already when using Alpine Linux 3.8.1 (a version of Alpine Linux which was not affected by the issue reported here).

## How was this patch tested?

Manually tested by running a simple workload with spark-shell, using docker on a client machine and using Spark on a Kubernetes cluster. The test workload is: `Seq(1,2).toDF("id").write.format("parquet").save("DELETEME1")`

Added a test to the KubernetesSuite / BasicTestsSuite

Marcelo Vanzin a6ddc9d083 [SPARK-24736][K8S] Let spark-submit handle dependency resolution.
Before this change, there was some code in the k8s backend to deal
with how to resolve dependencies and make them available to the
Spark application. It turns out that none of that code is necessary,
since spark-submit already handles all that for applications started
in client mode - like the k8s driver that is run inside a Spark-created
pod.

For that reason, specifically for pyspark, there's no need for the
k8s backend to deal with PYTHONPATH; or, in general, to change the URIs
provided by the user at all. spark-submit takes care of that.

For testing, I created a pyspark script that depends on another module
that is shipped with --py-files. Then I used:

- --py-files http://.../dep.py http://.../test.py
- --py-files http://.../dep.zip http://.../test.py
- --py-files local:/.../dep.py local:/.../test.py
- --py-files local:/.../dep.zip local:/.../test.py

Without this change, all of the above commands fail. With the change, the
driver is able to see the dependencies in all the above cases; but executors
don't see the dependencies in the last two. That's a bug in shared Spark code
that deals with local: dependencies in pyspark (SPARK-26934).

I also tested a Scala app using the main jar from an http server.

Jungtaek Lim (HeartSaVioR) c17150a5f5 [SPARK-22860][CORE][YARN] Redact command line arguments for running Driver and Executor before logging (standalone and YARN)
## What changes were proposed in this pull request?

This patch applies redaction to command line arguments before logging them. This applies to two resource managers: standalone cluster and YARN.

This patch only concerns about arguments starting with `-D` since Spark is likely passing the Spark configuration to command line arguments as `-Dspark.blabla=blabla`. More change is necessary if we also want to handle the case of `--conf spark.blabla=blabla`.

## How was this patch tested?

Added UT for redact logic. This patch only touches how to log so not easy to add UT regarding it.

seancxmao ce3a157f00 [SPARK-26939][CORE][DOC] Fix some outdated comments about task schedulers
## What changes were proposed in this pull request?
This PR aims to fix some outdated comments about task schedulers.

1. Change "ClusterScheduler" to "YarnScheduler" in comments of `YarnClusterScheduler`

According to [SPARK-1140 Remove references to ClusterScheduler](https://issues.apache.org/jira/browse/SPARK-1140), ClusterScheduler is not used anymore.

I also searched "ClusterScheduler" within the whole project, no other occurrences are found in comments or test cases. Note classes like `YarnClusterSchedulerBackend` or `MesosClusterScheduler` are not relevant.

2. Update comments about `statusUpdate` from `TaskSetManager`
`statusUpdate` has been moved to `TaskSchedulerImpl`. StatusUpdate event handling is delegated to `handleSuccessfulTask`/`handleFailedTask`.

## How was this patch tested?
N/A. Fix comments only.

Closes #23844 from seancxmao/taskscheduler-comments.

Liupengcheng eb6fd7eab7 [SPARK-26877][YARN] Support user-level app staging directory in yarn mode when spark.yarn…
Currently, when running applications on yarn mode, the app staging directory of  is controlled by `spark.yarn.stagingDir` config if specified, and this directory cannot separate different users, sometimes, it's inconvenient for file and quota management for users.

Sometimes, there might be an unexpected increasing of the staging files, two possible reasons are:
1. The `spark.yarn.preserve.staging.files` provided can be misused by users
2. cron task constantly starting new applications on non-existent yarn queue(wrong configuration).

But now, we are not easy to find out the which user obtains the most HDFS files or spaces.
what's more, even we want set HDFS name quota or space quota for each user to limit the increase is impossible.

So I propose to add user sub directories under this app staging directory which is more clear.

Marcelo Vanzin 61c3cdc706 [SPARK-24894][K8S] Make sure valid host names are created for executors.
Since the host name is derived from the app name, which can contain arbitrary
characters, it needs to be sanitized so that only valid characters are allowed.

On top of that, take extra care that truncation doesn't leave characters that

“attilapiros” e4e4e2b842 [SPARK-26891][YARN] Fixing flaky test in YarnSchedulerBackendSuite
The test "RequestExecutors reflects node blacklist and is serializable" is flaky because of multi threaded access of the mock task scheduler. For details check [Mockito FAQ (occasional exceptions like: WrongTypeOfReturnValue)](https://github.com/mockito/mockito/wiki/FAQ#is-mockito-thread-safe). So instead of mocking the task scheduler in the test TaskSchedulerImpl is simply subclassed.

This multithreaded access of the `nodeBlacklist()` method is coming from:
1) the unit test thread via calling of the method `prepareRequestExecutors()`
2) the `DriverEndpoint.onStart` which runs a periodic task that ends up calling this method

Gabor Somogyi 28ced387b9 [SPARK-26772][YARN] Delete ServiceCredentialProvider and make HadoopDelegationTokenProvider a developer API
## What changes were proposed in this pull request?

`HadoopDelegationTokenProvider` has basically the same functionality just like `ServiceCredentialProvider` so the interfaces can be merged.

`YARNHadoopDelegationTokenManager` now loads `ServiceCredentialProvider`s in one step. The drawback of this if one provider fails all others are not loaded. `HadoopDelegationTokenManager` loads `HadoopDelegationTokenProvider`s independently so it provides more robust behaviour.

In this PR I've I've made the following changes:
* Deleted `YARNHadoopDelegationTokenManager` and `ServiceCredentialProvider`
* Made `HadoopDelegationTokenProvider` a `DeveloperApi`

Jungtaek Lim (HeartSaVioR) b6c6875571 [SPARK-26790][CORE] Change approach for retrieving executor logs and attributes: self-retrieve
## What changes were proposed in this pull request?

This patch proposes to change the approach on extracting log urls as well as attributes from YARN executor:

 - AS-IS: extract information from `Container` API and include them to container launch context
- TO-BE: let YARN executor self-extracting information

This approach leads us to populate more attributes like nodemanager's IPC port which can let us configure custom log url to JHS log url directly.

Maxim Gekk a829234df3 [SPARK-26817][CORE] Use System.nanoTime to measure time intervals
## What changes were proposed in this pull request?

In the PR, I propose to use `System.nanoTime()` instead of `System.currentTimeMillis()` in measurements of time intervals.

`System.currentTimeMillis()` returns current wallclock time and will follow changes to the system clock. Thus, negative wallclock adjustments can cause timeouts to "hang" for a long time (until wallclock time has caught up to its previous value again). This can happen when ntpd does a "step" after the network has been disconnected for some time. The most canonical example is during system bootup when DHCP takes longer than usual. This can lead to failures that are really hard to understand/reproduce. `System.nanoTime()` is guaranteed to be monotonically increasing irrespective of wallclock changes.

## How was this patch tested?

By existing test suites.

Jungtaek Lim (HeartSaVioR) af4c59c0fb [SPARK-26843][MESOS] Use ConfigEntry for hardcoded configs for "mesos" resource manager
## What changes were proposed in this pull request?

This patch makes hardcoded configs in "mesos" module to use ConfigEntry, avoiding issues on mistake like SPARK-26082.

Please note that there're some changes on type while migrating to ConfigEntry: specifically "comma-separated list on a string" becomes "sequence of strings". While SparkConf smoothly handles on the change (comma-separated list on a string is still supported so backward compatible), there're some methods in utility class (`mesos` package private) to depend on the type change, so this patch also modifies the method signature for them a bit.

Jungtaek Lim (HeartSaVioR) ae5b2a6a92 [SPARK-26311][CORE] New feature: apply custom log URL pattern for executor log URLs in SHS
## What changes were proposed in this pull request?

This patch proposes adding a new configuration on SHS: custom executor log URL pattern. This will enable end users to replace executor logs to other than RM provide, like external log service, which enables to serve executor logs when NodeManager becomes unavailable in case of YARN.

End users can build their own of custom executor log URLs with pre-defined patterns which would be vary on each resource manager. This patch adds some patterns to YARN resource manager. (For others, there's even no executor log url available so cannot define patterns as well.)

Please refer the doc change as well as added UTs in this patch to see how to set up the feature.

## How was this patch tested?

Added UT, as well as manual test with YARN cluster
