Marcelo Vanzin b095232f63 [SPARK-29865][K8S] Ensure client-mode executors have same name prefix
This basically does what BasicDriverFeatureStep already does to achieve the
same thing in cluster mode; but since that class (or any other feature) is
not invoked in client mode, it needs to be done elsewhere.

I also modified the client mode integration test to check the executor name
prefix; while there I had to fix the minikube backend to parse the output
from newer minikube versions (I have 1.5.2).

Xingbo Jiang 007c873ae3 Prepare Spark release v3.0.0-preview-rc2
### What changes were proposed in this pull request?

To push the built jars to maven release repository, we need to remove the 'SNAPSHOT' tag from the version name.

Made the following changes in this PR:
* Update all the `3.0.0-SNAPSHOT` version name to `3.0.0-preview`
* Update the sparkR version number check logic to allow jvm version like `3.0.0-preview`

**Please note those changes were generated by the release script in the past, but this time since we manually add tags on master branch, we need to manually apply those changes too.**

We shall revert the changes after 3.0.0-preview release passed.

### Why are the changes needed?

To make the maven release repository to accept the built jars.

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

No

igor.calabria 78bdcfade1 [SPARK-27812][K8S] Bump K8S client version to 4.6.1
### What changes were proposed in this pull request?

Updated kubernetes client.

### Why are the changes needed?

https://issues.apache.org/jira/browse/SPARK-27812
https://issues.apache.org/jira/browse/SPARK-27927

We need this fix https://github.com/fabric8io/kubernetes-client/pull/1768 that was released on version 4.6 of the client. The root cause of the problem is better explained in https://github.com/apache/spark/pull/25785

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

Nope, it should be transparent to users

### How was this patch tested?

This patch was tested manually using a simple pyspark job

```python
from pyspark.sql import SparkSession

if __name__ == '__main__':
    spark = SparkSession.builder.getOrCreate()
```

The expected behaviour of this "job" is that both python's and jvm's process exit automatically after the main runs. This is the case for spark versions <= 2.4. On version 2.4.3, the jvm process hangs because there's a non daemon thread running

```
"OkHttp WebSocket https://10.96.0.1/..." #121 prio=5 os_prio=0 tid=0x00007fb27c005800 nid=0x24b waiting on condition [0x00007fb300847000]
"OkHttp WebSocket https://10.96.0.1/..." #117 prio=5 os_prio=0 tid=0x00007fb28c004000 nid=0x247 waiting on condition [0x00007fb300e4b000]
```
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

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.

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.

## How was this patch tested?

```bash
export SPARK_HOME=`pwd`
dev/make-distribution.sh --pip --tgz -Phadoop-2.7 -Pkubernetes

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

Stavros Kontopoulos 5e74570c8f [SPARK-23153][K8S] Support client dependencies with a Hadoop Compatible File System
## What changes were proposed in this pull request?
- solves the current issue with --packages in cluster mode (there is no ticket for it). Also note of some [issues](https://issues.apache.org/jira/browse/SPARK-22657) of the past here when hadoop libs are used at the spark submit side.
- supports spark.jars, spark.files, app jar.

It works as follows:
Spark submit uploads the deps to the HCFS. Then the driver serves the deps via the Spark file server.
No hcfs uris are propagated.

The related design document is [here](https://docs.google.com/document/d/1peg_qVhLaAl4weo5C51jQicPwLclApBsdR1To2fgc48/edit). the next option to add is the RSS but has to be improved given the discussion in the past about it (Spark 2.3).
## How was this patch tested?

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

```

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

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:

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

Note: While I was facing disk pressure issues locally on machine, I noticed minikube status command would report that everything was working fine even if some kube-system pods were not up. I don't think the output is 100% reliable but it is good enough for most cases.

Marcelo Vanzin dbd90e5440 [SPARK-26194][K8S] Auto generate auth secret for k8s apps.
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.

Rob Vesse 1144df3b5d [SPARK-26015][K8S] Set a default UID for Spark on K8S Images
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.

This is a Hadoop issue that fails to parse some java.version. It has been fixed from Hadoop-2.7.4(see [HADOOP-14586](https://issues.apache.org/jira/browse/HADOOP-14586)).

Note, Hadoop-2.7.5 or upper have another problem with Spark ([SPARK-25330](https://issues.apache.org/jira/browse/SPARK-25330)). So upgrading to 2.7.4 would be fine for now.

Nagaram Prasad Addepally 9b48107f9c [SPARK-25957][K8S] Make building alternate language binding docker images optional
## What changes were proposed in this pull request?
bin/docker-image-tool.sh tries to build all docker images (JVM, PySpark
and SparkR) by default. But not all spark distributions are built with
SparkR and hence this script will fail on such distros.

With this change, we make building alternate language binding docker images (PySpark and SparkR) optional. User has to specify dockerfile for those language bindings using -p and -R flags accordingly, to build the binding docker images.

## How was this patch tested?

Tested following scenarios.
*bin/docker-image-tool.sh -r <repo> -t <tag> build* --> Builds only JVM docker image (default behavior)

*bin/docker-image-tool.sh -r <repo> -t <tag> -p kubernetes/dockerfiles/spark/bindings/python/Dockerfile build* --> Builds both JVM and PySpark docker images

*bin/docker-image-tool.sh -r <repo> -t <tag> -p kubernetes/dockerfiles/spark/bindings/python/Dockerfile -R kubernetes/dockerfiles/spark/bindings/R/Dockerfile build* --> Builds JVM, PySpark and SparkR docker images.

[SPARK-25956] Make Scala 2.12 as default Scala version in Spark 3.0
## What changes were proposed in this pull request?

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.

Marcelo Vanzin e4561e1c55 [SPARK-25897][K8S] Hook up k8s integration tests to sbt build.
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.

Closes #22909 from vanzin/SPARK-25897.
