Ability to specify the "host" published in zookeeper
----------------------------------------------------

                 Key: HBASE-3254
                 URL: https://issues.apache.org/jira/browse/HBASE-3254
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 0.89.20100924
            Reporter: Eric Tschetter


We are running HBase on EC2 and I'm trying to get a client external from EC2 to 
connect to the cluster.  But, each of the nodes appears to be publishing its IP 
address into zookeeper.  The problem is that the nodes on EC2 see a 10. IP 
address that is only resolvable inside of EC2.

Specifically for EC2, there is a DNS name that will resolve properly both 
externally and internally, so it would be nice if I could tell each of the 
processes what host to publish into zookeeper via a property.  As it stands, I 
have to do ssh tunnelling/muck with the hosts file in order to get my client to 
connect.
 
This problem could occur anywhere that you have a different DNS entry for 
public vs. private access.  That might only ever happen on EC2, but it might 
happen elsewhere.  I don't really know :).
