Prasanth Jayachandran updated HIVE-12935:
-----------------------------------------
    Attachment: 12935.1.patch

This is the first take on the patch. Haven't tested secure zk client-server connection yet. There could be some more cleanup on LlapTaskSchedulerService. In case if something can be cleaned up will do so in follow up patches.

> 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.
