Mufeed Usman I followed the above steps. 1st i created a copy of both the directories and then run the cp -p command. after that i created a backup of the env.sh file and then added the 2 lines in it. the nodemanager not running alarm disappeared after that but it again came back after sometime. now it goes away and comes back at every 10 mins interval. could you provide a permanent solution to this. here is the output to the above commands you asked to run.
