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
