I think I figured it out. stop-yarn.sh and start-yarn.sh restarts resourcemanager on the same node but not on all other nodes. The workaround is to go to all rm nodes and start rm individually. I see that these scripts invoke another command yarn-daemon.sh which takes a argument --hosts. I tried to add this but dint do the trick. I atleast have a workaround but may not be optimal.
