Re: hbase error

Hi Wanli,

I can see that on your logs:

Failed to read: org.apache.zookeeper.KeeperException$NoNodeException:
KeeperErrorCode = NoNode for /hbase/root-region-server

and Read ZNode /hbase/root-region-server got 127.0.0.1:60020

It's connecting locally, no? Do you have your Quorum configured on
your hbase-site.xml

On your master, what is "bin/hbase zkcli" giving?

JM
