stack commented on HBASE-1778:
------------------------------

@Schubert: Thanks for updating to use new APIs.  One question.  What do you mean by the "approach to split maps is not strict".  Your additions look good, but please help me understand why the old was 'off'.  Thanks.

> 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.
