HBase 0.20.0 alpha not starting in distributed mode

[murali krishna]

Hi,
    just upgraded to hbase 20 alpha, it is refusing to start in distributed 
mode. Following is the exception coming from zookeeper

2009-06-24 03:14:48,005 WARN

I am seeing the HQuorumPeer, HMaster and HRegionserver process running. What 
could be wrong ?

Thanks,
