While restarting Livy and Livy2 on a non-root cluster, the following is seen:

```
This occurs because the PID file cannot be accessed by the non-root agent and
returns an exit code of 1:
{code}
call returned (1, 'cat: /var/run/livy/livy-cstm-livy-server.pid: Permission
denied')
{code}
This tricks out PID detection into thinking that there is no process running
(or a missing PID file) and therefore, we do not need to stop Livy/Livy2.
