Comment 1 for bug 1626736

The message:
 Two objects are equal when all of the attributes are equal, if you want to identify whether two objects are same one with same id, please use is_same_obj() function.
is strange, but it looks like it's just a warning from python-heatclient:

https://github.com/openstack/python-heatclient/blob/master/heatclient/openstack/common/apiclient/base.py#L526

I'd gather the failing error is
 <urlopen error [Errno 2] No such file or directory: '/usr/share/openstack-tripleo-heat-templates/overcloud-without-mergepy.yaml'>
