> Existing YARN registry service for cluster membership has to depend on
> refresh intervals to get the list of instances/daemons that are running in
> the cluster. Better approach would be replace it with zookeeper based
> registry service so that custom listeners can be added to update healthiness
> of daemons in the cluster.
