-----------------------------------------
Thanks for the review, [~vvasudev]. The log lines weren't added in this patch -
just re-indented. In any case, I'll make the fixes you proposed and upload a
new patch.
> Add cgroups support for docker containers

> 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.
