The jar in hbase/lib/ always needs to be exactly in sync with what you are running on the DNs. I believe there are a few additional HDFS patches applied to the Hadoop 0.20-append branch that HBase is building from, but as you may have seen recently on the general@hadoop list, there still is no official 0.20-append release. You're better off using the much better tested cdh3b2 Hadoop at this point. --gh On Tue, Dec 28, 2010 at 11:42 AM, Ted Yu wrote: > Hi, > I noticed this when trying to start 0.90 rc2: > > 2010-12-28 19:37:43,318 FATAL org.apache.hadoop.hbase.master.HMaster: > Unhandled exception.
