Subject Re: upgrading HBase 0.90.2 to HBase 0.94
Date Mon, 28 May 2012 15:40:34 GMT
 From 0.92.2 to 0.94, you can´t use rolling upgrade,because the wire 
protocol changed in these versions.
So, yo have to shutdown the cluster, install the new version, update the 
HBase classpath and start the cluster with
the new version
