Subject [jira] Created: (MAPREDUCE-1742) Job.setNumReduceTasks doesn't work
Date Thu, 29 Apr 2010 16:15:54 GMT
Job.setNumReduceTasks doesn't work

                 Key: MAPREDUCE-1742
                 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

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.
