> The Zeppelin alert check doesn't check the actual Zeppelin pid file. Instead it can pick up interpreter pid files.
> {code}
> pid_file = glob.glob(zeppelin_pid_dir + '/zeppelin-*.pid')[0]
> {code}
> This is wrong when there are multiple files in the pid dir starting with "zeppelin-".
> {code}
> ls -l /var/run/zeppelin/
