[jira] [Created] (MAPREDUCE-6487) TaskCounter.MAP_OUTPUT_BYTES is 0 for map-only jobs

Laurent Goujon created MAPREDUCE-6487:
-----------------------------------------

             Summary: TaskCounter.MAP_OUTPUT_BYTES is 0 for map-only jobs
                 Key: MAPREDUCE-6487
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6487
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: task
            Reporter: Laurent Goujon


It looks like DirectMapOutputCollector (used by Map-only jobs) doesn't update TaskCounter.MAP_OUTPUT_BYTES although it updates TaskCounter.MAP_OUTPUT_RECORDS.
