> 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.
