>                 URL: https://issues.apache.org/jira/browse/YARN-5645
>             Project: Hadoop YARN
>          Issue Type: Sub-task

> When launching docker containers, it is common to need to bind mount OS files and directories
into the container. YARN-5042 added /sys/fs/cgroup, however, other mounts will also be required
for specific use cases (such as /dev/urandom). 
> Allowing an administrator to define a while list of allowed mounts would avoid the need
to hard code these bind mounts each time a new need arises. Users could specify any mounts
they require through a similar mechanism as was added in YARN-4595, but with values checked
against the white list.
