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.
