>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2398
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: benchmarks
>    Affects Versions: 2.3.0
>            Reporter: Michael Noll
>            Assignee: Yang Hao
>            Priority: Minor
>         Attachments: MAPREDUCE-2398-trunk.patch, MAPREDUCE-2398_0.20.2.patch, MAPREDUCE-2398_v2-0.20.203.0.patch,

> 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.
