for some details - you can use mapreduce or pig to get data out of cassandra.  If it's going
to a separate hadoop cluster, I don't think you'd need to co-locate task trackers or data
nodes on your cassandra nodes - it would just need to copy over the network though.  We also
use oozie for job scheduling, fwiw.
