[jira] [Created] (YARN-5645) Support a white list of admin approved mounts.

Shane Kumpf created YARN-5645:
---------------------------------

             Summary: 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
            Reporter: Shane Kumpf
            Assignee: Shane Kumpf


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.
