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

Hi [~jagadesh.kiran] & [~brahmareddy]
I feel this is not a issue, as the usage of the command is to pass the Log name 
for example
/yarn daemonlog -setlevel xx.xx.xx.xxx:45020 
org.apache.hadoop.yarn.server.resourcemanager.rmapp.RMAppImpl  DEBUG

After running the above command you can run a yarn app and check the RM logs to 
find the debug logs for  
org.apache.hadoop.yarn.server.resourcemanager.rmapp.RMAppImpl.
If its working then will close this issue.
