RE: ANN: The first hbase 0.94.0 release candidate is available for download
Hi

When we tried to start the 0.94 version with hadoop 0.23.1 we got the
following exception stack trace.. Even 0.92.2 snapshot also had the same
problem.  

2012-03-30 11:12:19,487 FATAL org.apache.hadoop.hbase.master.HMaster:

I tried to build a jar with profile as 23 but still could not resolve this.
Am I doing some mistake with this?

Regards
Ram
