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.

Facing something strange...

I have been able to download and check the signature. I deployed on 4
nodes, but I'm getting that on stratup:

I have done a rm -r of the /hbase hdfs folder to get it clean.

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...
