While doing ./stack.sh, noticed in middle both senlin and heat moved from ocata to master branch and throwing errror as below

I am wondering why it is checking pike version, when I did checkout ocata branch.. ?

Well the error looks like you have several versions around. Maybe remove your pyc files in /opt/stack/heat. A git log of /opt/stack/heat would be useful too.

[maestropandy (maestropandy)]

yes, if clone devstack, definetly will have all versions and i did checkout to ocata and also all plugins like ceilometer, aodh, heat to stable/ocata, while cloning except heat.. other plugins properly cloning ocata branch, where heat initially in ocata branch.. after sometime it automatically swtiches to master ... so modules mismatching is happening

I just stacked with ocata devstack and heat. Did not see any of these issues. We also have stable branch dsvm jobs at the gate that are running fine. Probably something wrong with your setup.
