> The output directory for the reduces is not cleaned up and therefore if you can see left
overs from previous runs, if they had more reduces. For example, if you run the application
once with reduces=10 and then rerun with reduces=8, your output directory will have frag00000
to frag00009 with the first 8 fragments from the second run and the last 2 fragments from
the first run.
