MRBench allows Long-sized input-lines value but parses CLI argument as an Integer
---------------------------------------------------------------------------------

                 Key: MAPREDUCE-3990
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3990
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: test
    Affects Versions: 0.23.0
            Reporter: Harsh J
            Assignee: Harsh J
            Priority: Trivial
         Attachments: MAPREDUCE-3990.patch

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).
