Is it possible to submit a series of MR Jobs to the JobTracker to run in sequence (one finishes, take the output of that if successful and feed it into the next, etc), or does it need to run client side by using the JobControl or something like Oozie, or rolling our own? What I'm looking for is a fire & forget, and occasionally check back to see if it's done. So client-side doesn't need to really know anything or keep track of anything. Does something like that exist within the Hadoop framework?
