Harsh J updated MAPREDUCE-2398: ------------------------------- Assignee: (was: Yang Hao) > 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 > Reporter: Michael Noll > Priority: Minor > Attachments: MAPREDUCE-2398-trunk.patch, MAPREDUCE-2398.2.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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
