Setting up multiple clusters

Hi all,

I've followed Michael Noll's excellent guide to get Hadoop set up on a single cluster: http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/

I'd now like to get a second node set up to do some processing. In this guide, and all others I've seen, these other clusters are all on the same LAN. However, I am doing my project using a Virtual Machine that I was given by my university that I access using PuTTY by connecting to its IP address. Can I connect this machine, across Hadoop, to a different machine on an entirely different IP address? Is this even possible? I tried editing the /etc/hosts of both computers and storing the IP address like this:

117.118.45.205:127.0.0.1 localhost

With the real IP address first, then the "local" IP address after, but that didn't work. Does anybody have any suggestions, or is this simply not possible?
 
It is sorta covered in the JavaRanch Style Guide.
