stack commented on HBASE-3254:
------------------------------

Hey Cheddar.  You got a patch that would illustrate how you'd fix this (We should be using
hostnames rather than IPs I'd say)?

> 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 :).
