> Once a node reports a container running in a status update, the corresponding
> RMNodeImpl will track the container in its launchedContainers map. If the
> node somehow misses sending the completed container status to the RM and the
> container simply disappears from subsequent heartbeats, the container will
> leak in launchedContainers forever and the container completion event will
> not be sent to the scheduler.
