Jim Brennan reassigned YARN-8029:
---------------------------------
Assignee: Jim Brennan
I've put up a patch for this that changes the delimiter for the docker mount path variables to semicolon instead of comma.

> Key: YARN-8029
> URL: https://issues.apache.org/jira/browse/YARN-8029
> Project: Hadoop YARN
> Issue Type: Bug
> Components: yarn
> Affects Versions: 3.0.0
> Reporter: Jim Brennan
> Assignee: Jim Brennan
> Priority: Major
> Attachments: YARN-8029.001.patch
>
>
> The following docker-related environment variables specify a comma-separated list of mounts:
> YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS
> YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS
> This is a problem because hadoop -Dmapreduce.map.env and related options use comma as a delimiter. So if I put more than one mount in YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS the comma in the variable will be treated as a delimiter for the hadoop command line option and all but the first mount will be ignored.
