[jira] [Created] (YARN-7814) Remove automatic mounting of cgroups
into Docker containers
Shane Kumpf created YARN-7814:
---------------------------------
Summary: Remove automatic mounting of cgroups into Docker containers
Key: YARN-7814
URL: https://issues.apache.org/jira/browse/YARN-7814
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.
