> [HOD] Cleanup idle HOD clusters whose ringmaster nodes might have gone down
> ---------------------------------------------------------------------------

> Key: HADOOP-4938

> As mentioned in HADOOP-4937, sometimes in large cluster deployments, faulty
> nodes on which the ringmaster process comes up may go down after the cluster
> is successfully allocated. Such clusters fail to deallocate automatically
> even if the idleness limit of the cluster is exceeded. This is because the
> idleness is tracked by the ringmaster process which itself has gone down.
> As large number of nodes can get held up due to this, such clusters should be
> detected and deallocated in some manner.
