In packaging we package contrail built version of python-redis and using it in a freshly installed system.
[python-redis]
file = python-redis_2.8.0-1contrail1_all.deb <<<<<<<<<<<<<<<<<<<<<
md5 = a2c82a2b974ed10471570c09aef0673d
https://github.com/Juniper/contrail-packaging/blob/master/build/package_configs/ubuntu1204/havana/depends_packages.cfg

And in the contrail-packages, contrail-analytics requires python-redis (>= 2.4.9)
https://github.com/Juniper/contrail-packages/blob/master/debian/contrail/debian/control
Package: contrail-analytics
Architecture: any
Depends: adduser,
         contrail-lib (= ${binary:Version}),
         libprotobuf7,
         python-bottle (>= 0.11.6),
         python-contrail (= ${source:Version}),
         python-pkg-resources,
         python-redis (>= 2.4.9),<<<<<<<<<<<<<<<<<<<<<<<<<<<

However with python-redis= 2.4.9, observer is not coming up, Following is the error in observer.log, with python-redis_2.8.0-1contrail1_all.deb, we are not hitting this issue.
