> The optional {{-baseDir}} parameter lets user specify the base DFS path for output/input
of MRBench.
> However, the two private variables {{INPUT_DIR}} and {{OUTPUT_DIR}} (MRBench.java) are
not updated in the case that the default value of  {{-baseDir}} is actually overwritten by
the user. Hence any input and output is always written to the default locations ({{/benchmarks/MRBench/...}}),
even though the user-supplied location for {{-baseDir}} is created (and eventually deleted
again) on HDFS.
> The bug affects at least Hadoop 0.20.2 and the current trunk (r1082703) as of March 21,
2011.
