>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: yarn
>    Affects Versions: 3.0.0
>            Reporter: Jim Brennan
>            Assignee: Jim Brennan

> 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.
