> Configure exclude host file patch and start RM in HA mode
> # Add NM1 entry in exclude host and execute refreshnodes. NM1 will be decommissioned.
> # Switch RM. RM reads exlude hosts and update decommissioned nodes to 1
> # Remove NM1 entry from exclude hosts and execute refreshNodes.
> # Start NM1 nodemanager. Observer in the UI, activenode is 1 and decommissioned node
is 1.
> "Decommissioned Nodes" field in RM shows some value even though there is no decommissioned
node.
