Not sure if this helps... With CDH3B3 if you're using the hbase version that ships, when you install hbase, you're also installing zookeeper. So that each node has its own ZK config in /etc/zookeeper. (zoo.cfg)
You need to make sure that these zoo.cfg files match the versions on your zoo keeper machines. A quick thing to check... on a Region Server, do you see the line localhost in the file?
