----------------------------------------
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
