    Description

      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.
