             Summary: Add cgroups support for docker containers
                 Key: YARN-4553
                 URL: https://issues.apache.org/jira/browse/YARN-4553
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Sidharta Seethana
            Assignee: Sidharta Seethana


Currently, cgroups-based resource isolation does not work with docker 
containers under YARN. The processes in these containers are launched by the 
docker daemon and they are not children of a container-executor process. Docker 
supports a --cgroup-parent flag which can be used to point to the 
container-specific cgroups that are created by the nodemanager. This will allow 
the Nodemanager to manage cgroups (as it does today) while allowing resource 
isolation to work with docker containers.
