> If no input directories are specified, loadgen goes into a special mode where
> random data is generated and written. In that mode, setting the number of
> mappers (-m command line option) is overridden by a calculation. Instead, it
> should take into consideration the user specified number of mappers and fall
> back to the calculation. In addition, update the documentation as well to
> match the new behavior in the code.
