[jira] [Created] (ZEPPELIN-3215) 'pid' files cannot be deleted when interpreter is restarted.

Jaehoon Jeong created ZEPPELIN-3215:
---------------------------------------

             Summary: 'pid' files cannot be deleted when interpreter is restarted.
                 Key: ZEPPELIN-3215
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-3215
             Project: Zeppelin
          Issue Type: Bug
          Components: Interpreters
            Reporter: Jaehoon Jeong


When user click 'restart interpreter', pid file about interpreter can be remained.

But it can be removed when zeppelin is shutting down so it is not critical bug of zeppelin.

But zeppelin's shutdown process can kill another process if OS reuse pid that is used interpreter because 'zeppelin-daemon.sh' kill process with run/*.pid files.
