Sumit Mohanty commented on AMBARI-12510:
----------------------------------------

[~tctruong213], do you have a sample of the output on RHEL7? 

The change looks safe to me except I am not sure how to quickly verify that the status codes are the same for all OSes. I think the return codes of 0 and 3 are what the command should return based on http://refspecs.linuxbase.org/LSB_3.1.0/LSB-Core-generic/LSB-Core-generic/iniscrptact.html.

> Ambari-server failed to initalize the postgre db when postgresql packages are installed as part of Ambari installation on RHEL 7.1, and 7.0 in some scenario.  
> Ambari-server detects status of Postgre via the "service postgresql status" call, and perform regex on  the output for "running" or "stopped".   This works OK for RHEL 6, but not for RHEL 7 as its output may include "running" when postgres is not actually running.
