> 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.
