Dongjoon Hyun updated SPARK-29474:
----------------------------------
Affects Version/s: (was: 3.0.0)
3.1.0
> CLI support for Spark-on-Docker-on-Yarn
> ---------------------------------------
>
> Key: SPARK-29474
> URL: https://issues.apache.org/jira/browse/SPARK-29474
> Project: Spark
> Issue Type: Improvement
> Components: Spark Shell, YARN
> Affects Versions: 3.1.0
> Reporter: Adam Antal
> Priority: Major
>
> The Docker-on-Yarn feature is stable for a while now in Hadoop.
> One can run Spark on Docker using the Docker-on-Yarn feature by providing runtime environments to the Spark AM and Executor containers similar to this:
> {noformat}
> --conf spark.yarn.appMasterEnv.YARN_CONTAINER_RUNTIME_TYPE=docker
> --conf spark.yarn.appMasterEnv.YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=repo/image:tag
> --conf spark.yarn.appMasterEnv.YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS="/etc/passwd:/etc/passwd:ro,/etc/hadoop:/etc/hadoop:ro"
> --conf spark.executorEnv.YARN_CONTAINER_RUNTIME_TYPE=docker
> --conf spark.executorEnv.YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=repo/image:tag
> --conf spark.executorEnv.YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS="/etc/passwd:/etc/passwd:ro,/etc/hadoop:/etc/hadoop:ro"
> {noformat}
> This is not very user friendly. I suggest to add CLI options to specify:
> - whether docker image should be used ({{--docker}})
> - which docker image should be used ({{--docker-image}})
> - what docker mounts should be used ({{--docker-mounts}})
> for the AM and executor containers separately.
> Let's discuss!
