YARN resourc manager


I had set up a HA cluster, using two masters. Starting dfs  works correctly, starting the journalnode,DFSZKFailover, quorumpeermain, and namenode processes without errors.  However, when starting YARN, the resource manager process is only started on one master.  I am able to manually start the YARN process on the second master. I have checked my configuration file yarn-site.xml and  am unable to find the problem.  I am attaching my yarn-site.xml file.  Thank you.

Hi Joe,

YARN Resource Manager is similar to JobTracker in Hadoop 1.x versions so only one Resource Manager will be there in hadoop cluster

Hope this helps.
