Actual results:

/usr/lib/python2.6/site-packages/babel/__init__.py:33: UserWarning: Module backports was already imported from /usr/lib64/python2.6/site-packages/backports/__init__.pyc, but /usr/lib/python2.6/site-packages is being added to sys.path
  from pkg_resources import get_distribution, ResolutionError

Expected results:

seems we have a problem with the cli

Additional info:
Comment 1 Jakub Ruzicka 2013-10-30 12:45:37 UTC 
I can't reproduce this on RHEL 6.5 beta with latest RHOS puddle. 

Also, this warning doesn't seem related to gluster cinder backend as cinderclient doesn't care about such things.

Can you reproduce this with latest puddle? Did you do something extra beyond packstack install?
Comment 2 Dafna Ron 2013-10-30 12:55:03 UTC 
yep, its no longer happening in the latest puddle. 
However, you should know that I am working with the rdo package: 
python-backports-1.0-4.el6.x86_64.rpm

if this package has no effect at all on cli please move this to on_qa for latest build and I will move to verify.
Comment 3 Jakub Ruzicka 2013-10-31 09:56:13 UTC 
That version contains Pádraig's quick fix.

However, I can't reproduce even with RHOS
python-backports-ssl_match_hostname-3.2-0.2.1.a3.el6.noarch

I'm moving to ON_QA as requested, but I think it's worth an additional check by someone else then me before moving to VERIFIED.

Párdaig, do you know what triggered this? Can it happen in RHOS?
Comment 4 Pádraig Brady 2013-10-31 10:39:02 UTC 
There may be some mixing of RDO and RHOS going on here.
We shouldn't do that ask it may mask/cause various issues.
A guess is the RHOS system under test had python-backports-1.0-3 installed
which triggers the issues in the keystone puppet modules at least.
Comment 5 Yogev Rabl 2013-11-05 11:56:21 UTC 
verified with version: openstack-cinder-2013.2-1.el6ost.noarch
Comment 7 Scott Lewis 2013-12-16 18:56:40 UTC 
Auto qa_ack+ for VERIFIED bugs so they can be added to RC erratum
