----------------------------------
Attachment: random-writer.patch

> and Counters
> -----------------------------------------------------------------------------------------

> Reporter: Owen O'Malley
> Assigned To: Owen O'Malley

>
> It would be good if the RandomWriter example used custom InputFormat and
> OutputFormats rather than creating temporary files in DFS. It is not only
> faster, it provides a better example to users of how to handle programs that
> don't have any input. (It still uses FileSplits rather than custom
> InputSplits, since the FileSplits would do want I need.)
> I also added Counters to the example to count records and bytes written.
