Moon, > ZeppelinServer try to terminate interpreter process when shutting down [1].
Unfortunatally, this does not happen all the time. I have seen zombie spark interpreter processes many times. As a double conirmation - I see spark yarn application was still running. > Also bin/zeppelin-deamon.sh script clean up if some processes are left [2]. We were not using that script. We were just running like zeppelin.sh --config .. Will try to switch to zeppelin-deamon.sh and see if it makes a difference.
