> If AM release a container, and container completes not killed by rm, there is a race condition the container complete msg are lost, because In  RMNodeImpl.handleContainerStatus:
>       if (containersToClean.contains(containerId)) {
>         LOG.info("Container " + containerId + " already scheduled for "
>             + "cleanup, no further processing");
>         continue;
>       }
