[SPARK-27936][K8S] Support python deps by skonto · Pull Request #25870 · apache/spark

skonto · 2019-09-20T15:33:03Z

What changes were proposed in this pull request?

Supports python client deps from the launcher fs.

Why are the changes needed?

This is a feature that was added for java deps. This PR adds support fo rpythona s well.

Does this PR introduce any user-facing change?

yes

How was this patch tested?

Manually running different scenarios and via examining the driver & executors logs. Also there is an integration test added.
I verified that the python resources are added to the spark file server and they are named properly so they dont fail the executors. Note here that as previously the following will not work:
primary resource A.py: uses a closure defined in submited pyfile B.py, context.py only adds to the pythonpath files with certain extension eg. zip, egg, jar.

@erikerlandson @holdenk pls review. I know there are some other changes (other PRs) related to the tests, I can always rebase if they get merged first.

+ .set("spark.hadoop.fs.s3a.impl", "org.apache.hadoop.fs.s3a.S3AFileSystem")
+ .set("spark.jars.packages", "com.amazonaws:aws-java-sdk:" +
+ "1.7.4,org.apache.hadoop:hadoop-aws:2.7.6")
+ .set("spark.driver.extraJavaOptions", "-Divy.cache.dir=/tmp -Divy.home=/tmp")


I can refactor this part to have the properties set once as they are shared with the existing test. In general I think we should separate the Suites in the future to allow better setup for before and after conditions.

holdenk · 2019-09-21T01:23:01Z

cc @ifilonenko who I think did some related work?

skonto · 2019-09-30T12:44:55Z

@erikerlandson if you have some free time pls have a look :)

erikerlandson · 2019-09-30T15:27:27Z

@skonto this LGTM

holdenk

Follow up question re: uploading.

skonto · 2019-10-11T10:02:30Z

@holdenk this is because spark-submit adds the resource to the sparks.jars property by default,
check bellow:

Classpath elements:

So since the PR here uploads whatever is needed from spark.jars we dont need to do double work. For python its different as technically the main resource is not a jar.

skonto · 2019-10-16T13:25:14Z

@erikerlandson I added one test which uses a zip file as we discussed previously:

ls tests/
py_container_checks.py py_container_checks.zip pyfiles.py worker_memory_check.py
Run starting. Expected test count is: 3
KubernetesSuite:
- Launcher java client dependencies
- Launcher python client dependencies using py
- Launcher python client dependencies using a zip file

In general there are many ways to setup the python env for a python Spark job at the driver/executor side: https://medium.com/criteo-labs/packaging-code-with-pex-a-pyspark-example-9057f9f144f3
but at least we cover the basic ones.

Minor comment about Python 2, but really excited to see this.

holdenk · 2019-10-17T06:05:46Z

+ val (accessKey, secretKey) = getCephCredentials()
+ sparkAppConf
+ .set("spark.kubernetes.container.image", pyImage)
+ .set("spark.kubernetes.pyspark.pythonVersion", "2")


Lets not use Python 2 since this is targeted for Spark 3 I believe.

I got used to 2 for years will miss it :) Sure will change.

I'm also back after my motorcycle crash last year, let me know when it's up to date and I'd be happy to take another look. Thanks for sticking with this.

erikerlandson · 2020-07-19T20:18:05Z

I notice this is targeted for 3.1, is it worth trying to get on the 3.0.1 train?

holdenk · 2020-07-19T21:43:24Z

I think the plan is to cut 3.0.1 pretty soon since there are some almost show stopper bugs in 3.0 so I’d leave it targeted to 3.1 and once it’s in we can discuss if backporting makes sense.

dongjoon-hyun · 2020-07-20T22:09:42Z

+1 for @holdenk 's comment. Also, in general, we cannot backport the improvement JIRA.

…tainer` ### What changes were proposed in this pull request? This PR aims to simply steps to re-write primary resource in k8s spark application. ### Why are the changes needed? Re-write primary resource uses `renameMainAppResource` twice. * First `renameMainAppResource` in `baseDriverContainer` in is introduced by #23546 * #25870 refactors `renameMainAppResource` and introduces `renameMainAppResource` in `configureForJava`. Refactoring and `renameMainAppResource` in `configureForJava` makes `renameMainAppResource` in `baseDriverContainer` useless. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? * Pass the GA. * Pass k8s IT. ``` $ build/sbt -Pkubernetes -Pkubernetes-integration-tests -Dtest.exclude.tags=r -Dspark.kubernetes.test.imageRepo=kubespark "kubernetes-integration-tests/test" [info] KubernetesSuite: [info] - Run SparkPi with no resources (17 seconds, 443 milliseconds) [info] - Run SparkPi with no resources & statefulset allocation (17 seconds, 858 milliseconds) [info] - Run SparkPi with a very long application name.

This PR can pass `DepsTestsSuite`, which can prove deletion about `renameMainAppResource` in `baseDriverContainer` does not affect the process about re-write primary resource.
