> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: benchmarks
> Affects Versions: 2.0.0-alpha
> Reporter: Harsh J
> Assignee: Harsh J
> Priority: Trivial
> Labels: mrbench
> Fix For: 3.0.0

>
> 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).
