HBase 0.20.0 alpha not starting in distributed mode
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 org.apache.hadoop.hbase.zookeeper.ZooKeeperWrapper: Failed to create /hbase:
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase

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

Jean,
My mistake, had given a wrong machine name in zoo.cfg, the zookeeper server was not running in that box :(.
Everything resolved now, thanks!
Thanks,
Murali Krishna

Murali,
fyi hbase.master is obsolete as the master can now be on any machine.
That failure usually means that there is a connection problem because some
address is localhost or a machine is using a hostname that's not in a DNS.
Can you make sure your Master resolves it's addrress correctly? It should
say something like "my address is...". Also could you enable DEBUG (look at
the FAQ to see how) and show your master log?
Thx,

Murali,
First, thanks for trying out this alpha release, it is very appreciated.
Can we see your conf/zoo.cfg and conf/hbase-site.xml?
