There is nothing in HBase natively that will do this but no reason you can't do this in a map or reduce task. You'd set up two or more HTable instances on task init each pointing to a particular table. Then, inside in your task you'd send the puts to one of the possible HTables switching on whatever your fancy. St.Ack
