> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Shane Kumpf

> 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.
