Owen O'Malley updated HADOOP-2376:
----------------------------------

    Attachment: sort-no-maps.patch

This just pulls out the code from the example that is trying to pick a good number of maps. Letting it match the number of input blocks is a much better idea.

> The sort example currently overrides the number of maps. It should just take the default, because the current behavior can end up with a bad number of maps by default. In particular, I had a small data set where the sort picked too many maps and split blocks badly.
