> Current PerformanceEvaluation class have two problems:
> - It is not updated for hadoop-0.20.0.
> - The approach to split maps is not strict. Need to provide correct InputSplit and InputFormat classes. Current code uses TextInputFormat and FileSplit, it is not reasonable.
> We will fix these problems.
