---------------------------------

             Summary: Create a thread in TezAM which periodically fetches 
LlapDaemon metrics
                 Key: HIVE-21846
                 URL: https://issues.apache.org/jira/browse/HIVE-21846
             Project: Hive
          Issue Type: Sub-task
          Components: llap, Tez
            Reporter: Peter Vary


LlapTaskSchedulerService should start a thread which periodically fetches the 
LlapDaemon metrics and stores them in the NodeInfo object.

This should be just the first implementation - later we should find a way where 
we do not need NxM requests between N TezAM and M LlapDaemon
