Hi Srini, Did you start the NodeManager process on node "C"? "yarn rmadmin -refreshNodes" does not remotely start processes on the NodeManager nodes if that is what you mean.
If you haven't already, you might want to take a look at the cluster setup guide for Hadoop: http://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/ClusterSetup.html On Tue, May 20, 2014 at 10:56 PM, Srinivas Reddy Kancharla < [email protected]> wrote: > Hi Gary, > > Thank you for this information.
