The shell will work on the same host as the server. The region server and master are bound
to the localhost interface. Any remote client connecting to ZK to find these addresses will
get localhost addresses. So the question is why the master and region server sockets are bound
to lo. This is some kind of configuration problem. 

- Check your hosts file on the server. Do you have a line like '127.0.0.1 server-hostname'?
Remove it. 

- Check that reverse DNS is set up correctly to resolve the IP of the public interface on
the server to a valid hostname (Hadoop DNS class requires this)

- Try using hbase.regionserver.dns.interface to specify the name of the public interface on
the server.

Subject: Re: Hbase Client problem



The hbase shell commands on unbuntu work fine.  
 
I will port my client code over to Ubuntu and try it there.  I tried a simple java client
running outside of JBOSS trying to talk to hbase and have the same issue.  From a novice point
of view it appears that the client can connect to the zookeeper, but it is unable to get to
the region server from the ip address given.  Hence it cannot connect to the region server
127.0.1.1:XXXXX.

How is the client over on ubuntu?  If you try the cell there?  Does it work?
