             Summary: LLAP: Act on Node update notifications from registry, fix isAlive checks
                 Key: HIVE-15242
                 URL: https://issues.apache.org/jira/browse/HIVE-15242
             Project: Hive
          Issue Type: Task
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth


isAlive checks are currently completely broken, since the ZK registry does not update existing ServiceIsntances. Instead it creates new instances each time.
This causes non-existant nodes to be used for scheduling in case of node failures.

Also, act on the notifications sent by the registry about nodes going down, or new nodes being added. (new nodes already handled)
