---------------------------------------
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.
