> 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.
