How to decommission a node in MR cluster
Hi,
I'm running hadoop 2.2.0, and I have one node which only has NodeManager
running(not a data node), now I want to decommission it from MR cluster and
followed below steps
1. add node to the file(yarn.resourcemanager.nodes.exclude-path in
yarn-site.xml)
2. run "yarn rmadmin -refreshNodes"
But nothing happened, what's wrong here?
Thanks

No, it's strange I cannot see anything in yarn-resourcemanager.log
