Hopefully this question isn't off topic. I asked this on AskUbuntu but haven't gotten a responses:
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:
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?
