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,
