[jira] [Created] (ZEPPELIN-79) Zeppelin does not kill some interpreters when server is stopped

Jonathan Kelly created ZEPPELIN-79:
--------------------------------------

             Summary: Zeppelin does not kill some interpreters when server is stopped
                 Key: ZEPPELIN-79
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-79
             Project: Zeppelin
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.5.0
            Reporter: Jonathan Kelly
             Fix For: 0.5.0


When the Zeppelin server is stopped (e.g., with a SIGTERM), it should also stop all interpreter processes that it has started.  Instead, I sometimes see them hang around as orphaned children after the Zeppelin server has stopped.  This seems to be the case with the spark interpreter (at least with yarn-client mode; haven't tested with standalone or local modes) and with the shell interpreter.  It does not seem to occur with the hive or angular interpreters; those ones stop when the server is stopped.
