So does that mean that HDFS will break a file at exactly <blocksize> bytes? Map/Reduce *does* operate with records in mind, so what happens to the split record? Does HDFS put the fragments back together and deliver the reconstructed record to one map? Or are both fragments and consequently the whole record discarded? Thanks, -Kelly
