As far as replication goes, you should look at a project called pastry. Apparently some people have used hadoop mapreduce on top of it. You will need to be clever, however, in how you do your mapreduce because you probably won't want the job to eat all the users cpu time.

Can someone else comment on whether HOD (hadoop-on-demand) would fit this scenario? Bill -----Original Message----- From: Maciej Trebacz [mailto: maciej.treb...@gmail.com] Sent: Wednesday,...
