> ambari-server stop kills parent process
> ---------------------------------------
>
> Key: AMBARI-12238
> URL: https://issues.apache.org/jira/browse/AMBARI-12238
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.0.1, 2.1.0
> Reporter: Greg Hill
>
> When you do ambari-server stop inside a script, it kills the calling script
> as well. This is because ambari-server stop kills the entire process group,
> but ambari-server start does not detach itself from the parent process.
> 'stop' kills the whole process group:
> https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/python/ambari-server.py#L145
> 'start' does not detach from its parent:
> https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/python/ambari_server_main.py#L276
> If you add an os.setsid() call to the start process, I think that would fix
> the bug, but more research/testing is needed:
> https://docs.python.org/2/library/os.html#os.setsid
