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: 0.20.2
Reporter: Michael Noll
Priority: Minor
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.
