Not able to start/stop hadoop daemons

0 votes

Hi, I am not able to start/stop the hadoop daemons. Currently, I have below list of daemons running: 

3871 Jps 
1853 NodeManager 
1734 DataNode 
1797 ResourceManager 

I tried to stop all daemons, but got below error: 

$ sudo ./stop-all.sh 
no org.apache.spark.deploy.worker.Worker to stop 
no org.apache.spark.deploy.master.Master to stop

If you were able to start the daemons, you should also be able to stop them. Are you stopping the daemons as the same user that started them? Sometimes when you switch users, you get this error.
