> When executing {{ambari-server start}} command via ssh, process hangs.
> Reproducible only when executing ambari-server start without login only on Ubuntu
> {code}
> andrew@pc:~/vagrant/ubuntu12.4$ ssh -i ../insecure_private_key root@u1201 "ambari-server start"
> Using python  /usr/bin/python2.7
> Starting ambari-server
> Ambari Server running with 'root' privileges.
> About to start PostgreSQL
> Organizing resource files at /var/lib/ambari-server/resources...
> Server PID at: /var/run/ambari-server/ambari-server.pid
> Server out at: /var/log/ambari-server/ambari-server.out
> Server log at: /var/log/ambari-server/ambari-server.log
> Waiting for server start....................
> Ambari Server 'start' completed successfully.
> {code}
> User need to drop ssh connection afterwards.
> This affects our QA automation tests, because we need to create workaround for it.
> Per my investigations, in tests we can now make something like:
> {code}
> ssh root@host "ambari-server start < /dev/null > /tmp/ambari-start-log 2>&1 &"
> {code}
> But this will breaks our ability for easily checking outputs of ambari-server
> We had similar bug before, but for different OS
