I have noticed that the Reducer does not enforce that the key is kept unaltered after the reduce operation. What would happen if output with a different key was collected? I realize that the output would no longer be sorted, but would it cause the job to fail?
I believe it will work fine. The collector that is passed to the reduce is just a wrapper around the SequenceFile.Writer. SequenceFile.Writer is more than willing to write unsorted files.
