Hi Noorul,

Here's the link to the more recently written 'Openstack CI documentation' which has some additional details you might find helpful [1].
It mentions zuul and the zuul  mergers [2]

Indeed! Thanks a lot! It worked after running zuul-merger on same zuul node. The documentation
(http://docs.openstack.org/infra/system-config/running-your-own.html)
does not mention anything about merger. And it looks like merger puppet module assumes zuul-merger will be running on separate node.

Thanks and Regards
Noorul
