Short, blind answer: You could run 10 reducers. Otherwise, you'll have to run another job that picks up a few files each in mapper and merges them out. But having 60 files shouldn't really be a problem if they are sufficiently large (at least 80% of a block size perhaps -- you can tune # of reducers to achieve this).
