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
> MRBench: setting the baseDir parameter has no effect

> Key: MAPREDUCE-2398
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2398
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: benchmarks
> Affects Versions: 2.3.0, 0.22.0, 0.20.2, 2.4.0, 2.5.0
> Reporter: Michael Noll
> Assignee: Yang Hao
> Priority: Minor
> Fix For: 1.3.0, 2.5.0
>
> Attachments: MAPREDUCE-2398-trunk.patch, MAPREDUCE-2398_0.20.2.patch,
> MAPREDUCE-2398_v2-0.20.203.0.patch, MAPREDUCE-2398_v2-trunk.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.
