I don't think that your error is related to CPs stuff. What lib versions do you use? Can you compare with those of the HBaseHUT pom?
Re 127.0.1.1 vs 127.0.0.1 - what your hosts file looked like before and now? I think it's just the issue with resolving IP - at one place it resolves using localhost, at other - your hostname. Since (I suppose) those two didn't match - you got error.
