Can you tell me a little about how HBase works with MR? If the MR source/sink has to go through just ONE region client, then it is not I am looking for. But if MR can plug directly with the region server containing specific rows, then it might work. Furthermore, MR is a heavy weight process with lots of overhead. Ideally, we want something light weight and can get result fast. Many thanks.
