> Caused by YARN-1372. thanks [~vinodkv] for pointing  this out.
> The problem is that in YARN-1372 we changed the behavior to remove containers from NMContext
only after the containers are acknowledged  by AM. But in the {{NodeStatusUpdaterImpl#removeCompletedContainersFromContext}}
call, we didn't check whether the container is really completed or not.  If the container
is stilll running, we shouldn't remove the container from the context
