[jira] [Created] (MAPREDUCE-5292) ShuffleConsumerPlugin.Context should support org.apache.hadoop.mapreduce.Reducer

Tsuyoshi OZAWA created MAPREDUCE-5292:
-----------------------------------------

             Summary: ShuffleConsumerPlugin.Context should support org.apache.hadoop.mapreduce.Reducer
                 Key: MAPREDUCE-5292
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5292
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: trunk
            Reporter: Tsuyoshi OZAWA
            Assignee: Tsuyoshi OZAWA
            Priority: Blocker


ShuffleConsumerPlugin.Context only supports org.apache.hadoop.mapred.Reducer currently. Because of this, Reduce side Combiner is not used when using the new API, and just ignored. Please see MAPREDUCE-5221 for more detail.
