-------------------------------
Resolution: Duplicate
> Support a white list of admin approved mounts
> ---------------------------------------------
>
> Key: YARN-5645
> URL: https://issues.apache.org/jira/browse/YARN-5645
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: yarn

> 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.
