Yang Hao updated MAPREDUCE-2398:
--------------------------------

                 Tags: MRBench
        Fix Version/s:     (was: 0.22.1)
                       2.5.0
                       1.3.0
             Assignee: Yang Hao
     Target Version/s: 2.3.0, 2.5.0
    Affects Version/s: 2.5.0
                       2.4.0
                       2.3.0
               Status: In Progress  (was: Patch Available)

This problem still exists in the version Hadoop-2.3.0, so please fix it in the  java "org.apache.hadoop.mapred.MRBench".Sometimes we don't have the permission to operate all the HDFS file, so we have to change the BASE_DIR , and the INPUT_DIR and OUTPUT_DIR should be updated when BASE_DIR is set. Only two extra lines be put into the java source code can solve the bug

> 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.
