Description

MRBench has the following method:

public void generateTextFile(FileSystem fs, Path inputFile, long numLines, Order sortOrder) { ... }

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).
