Shane Kumpf commented on YARN-7814:
-----------------------------------
Thanks, [[email protected]]. I did see that one and considered just
re-purposing it, but it seemed it was aiming towards adding other options as
well. If you'd prefer, we can re-purpose that for outright removal of the
automatic mounting. I also think YARN-7231 and YARN-7232 can be closed if
everyone agrees the automatic mounting can be removed.

> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Shane Kumpf
> Assignee: Shane Kumpf
> Priority: Major
>
> Currently, all Docker containers launched by {{DockerLinuxContainerRuntime}}
> get /sys/fs/cgroup automatically mounted. Now that user supplied mounts
> (YARN-5534) are in, containers that require this mount can request it (with a
> properly configured mount whitelist).
> I propose we remove the automatic mounting of /sys/fs/cgroup into Docker
> containers.
