As visible from following OOM charts:

dmaap/charts/message-router/charts/message-router-kafka/values.yaml: 
dmaap/charts/message-router/charts/message-router-zookeeper/values.yaml: 

DMAAP requires casablanca branch of repo,

what is also interesting that current version based on 3.0.1 tag is not at all in casablanca branch, mentioned in DMAAP-1144. 

#application configuration

config:

1. gerrit branch where the latest code is checked in
   gerritBranch: casablanca
2. gerrit project where the latest code is checked in
   gerritProject:http://gerrit.onap.org/r/dmaap/messagerouter/messageservice.git

we need to align our bare repo to be created with expected version, which is also safer to align for other repos.
