                 Key: HADOOP-3424
                 URL: https://issues.apache.org/jira/browse/HADOOP-3424
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.17.0
            Reporter: Owen O'Malley
            Assignee: Chris Douglas


Since HADOOP-2919, map tasks haven't complained if getPartition returns numbers outside of
the valid range. This leads to applications where some of the transient output is ignored
(all of the rows marked for reduce -1, for example, are discarded, because reduce -1 doesn't
exist.)
