             Summary: Better debugging for agent start failure due to stuck fuser call
                 Key: AMBARI-24560
                 URL: https://issues.apache.org/jira/browse/AMBARI-24560
             Project: Ambari
          Issue Type: Bug
            Reporter: Andrew Onischuk
            Assignee: Andrew Onischuk
             Fix For: 3.0.0


While debugging with we encountered an issue where call to `fuser 8670/tcp` it got blocked for minutes
- in fact we did not ever see the agent start and had to comment the call. Two
improvements:

  * Need timeout for such calls (lets also research and see why the call may get stuck). We checked that the port was free.
  * Need more debug logging in the initial start up path to help debug what command is getting stuck - in main.py, and PingPortListener.py lets see if more debug logging can be added
