[jira] [Created] (ZEPPELIN-3201) Detached Zeppelin processes after server shutdown

Jasper Knulst created ZEPPELIN-3201:
---------------------------------------

             Summary: Detached Zeppelin processes after server shutdown
                 Key: ZEPPELIN-3201
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3201
             Project: Zeppelin
          Issue Type: Bug
          Components: zeppelin-interpreter
    Affects Versions: 0.7.2
            Reporter: Jasper Knulst


If you check the number of Zeppelin processes running after the server has been up for a while (ps aux | grep zeppelin) there are a lot of very old OS level processes around. They seem to be detached somehow (if you kill them nobody would notice it) and can run into hundreds of them.

Moreover, if you shut down the Zeppelin server and run " ps aux | grep zeppelin " there are also lots of detached processes not under management of the server anymore. Some of those are isolated, impersonated shell processes belonging to the %sh interpreter.

I created script to clean-up but the server should be aware of its child processes and manage them, especially on shut down.
