Map Reduce on Cassandra Store
Hello!
Has anyone tried to run MapReduce analytics on data stored in Cassandra? I feel like I saw a patch once to get hadoop working on top of Cassandra, but I can't find it now. I know that Hadoop integration is big on people's wishlists for future versions of Cassandra, but I'm just curious as to what's available now.
Can anybody out there lend me a hand, or should I stick to HBase? Thanks a lot!

There's no easy way to do it now, but I know we will certainly need it
at some point (as will others), so I'm sure it will eventually happen.
