Subject [jira] [Created] (MAPREDUCE-3182) loadgen ignore -m command line when using writing random data
Date Thu, 13 Oct 2011 21:56:11 GMT
loadgen ignore -m command line when using writing random data
-------------------------------------------------------------

                 Key: MAPREDUCE-3182
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3182
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2, test
    Affects Versions: 0.23.0, 0.24.0
            Reporter: Jonathan Eagles
            Assignee: Jonathan Eagles


If no input directories are specified, loadgen goes into a special mode where random data
is generated and written. In that mode, setting the number of mappers (-m command line option)
is overridden by a calculation. Instead, it should take into consideration the user specified
number of mappers and fall back to the calculation. In addition, update the documentation
as well to match the new behavior in the code.
