This is (somewhat expected) after HBASE-7600. A wipe of HDFS needs to be followed by a wipe of the /hbase folder in ZK. I filed HBASE-10145 for further discussion, yesterday.

I have been able to download and check the signature. I deployed on 4 nodes, but I'm getting that on stratup: 2013-12-13 17:19:26,373 FATAL [master:hbasetest1:60000] master.HMaster: Unhandled exception.

I have been able to start after clearing ZK too. But not sure if this is something we want to address or not. I will continue my tests...
