>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1742
>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: job submission
>    Affects Versions: 0.22.0
>         Environment: Hadoop 0.22.0-SNAPSHOT, latest version from trunc.
>            Reporter: Danny Leshem
>            Priority: Blocker
>
> Calling Job.setNumReduceTasks(0) doesn't seem to work with the latest trunc, and the job still goes through a reduction phase.
> Also, Job.setNumReduceTasks(1) doesn't seem to work either, and several reducers are spawned.
> It seems that something about Job.setNumReduceTasks got broken recently.
