Little? Check out the Import.java in mapreduce package. See how its pulling from SequenceFiles into a map that outputs to a TableOutputFormat inside in the map. Make a new MR job that has same input but that outputs to HFileOutputFormat instead (you'll need the total order partitioner and a reducer in the mix which Import doesn't have). St.Ack
