> MRBench has the following method:
> {code}
> public void generateTextFile(FileSystem fs, Path inputFile, long numLines, Order sortOrder)
{ ... }
> {code}
> The method is already set to accept a long datatype for numLines, for generating very
large amount of data.
> However, in {{MRBench#run(...)}}, the inputLines CLI parameter is parsed via an Integer.parseInt,
causing numbers passed > Integer.MAX_VALUE to throw NumberFormatExceptions as a result.
> The parsing should be Long.parseLong and the inputLines datatype should be switched to
the same type as passed to the method (long).
