             Summary: Zeppelin Alert checks wrong pid file
                 Key: AMBARI-22834
                 URL: https://issues.apache.org/jira/browse/AMBARI-22834
             Project: Ambari
          Issue Type: Bug
          Components: alerts
    Affects Versions: trunk, 2.6.2
            Reporter: Kevin Risden


The Zeppelin alert check doesn't check hte actual Zeppelin pid file. Instead it can pick up interpreter pid files.

{code:python}
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:bash}
ls -l /var/run/zeppelin/
-rw-r--r-- 1 zeppelin hadoop 7 Jan 16 12:01 zeppelin-interpreter-livy-zeppelin-HOSTNAME.pid
-rw-r--r-- 1 zeppelin hadoop 7 Jan 16 11:56 zeppelin-zeppelin-HOSTNAME.pid
{code}
