Currently the only cluster configuration that is done is a cluster_info file is populated on each node (parent and children) with the IP addresses and their level. something like:
123.45.67.890=parent 123.45.67.891=child 123.45.67.892=child etc This cluster_info file is either in /etc for linux or C: for windows So with that info an image creator can use that file from and init scripts and start their cluster. We have several hadoop clusters here at NCSU using this method, it's simple but seems to work well. In the future we would be better served using configuration managers like puppet, chef, bcfg2, etc. (We should put this on the roadmap.. :) ) Hope this helps.
