[jira] [Created] (MAPREDUCE-5941) JobCounter's should be organized in groups for map and reduce

Gera Shegalov created MAPREDUCE-5941:
----------------------------------------

             Summary: JobCounter's should be organized in groups  for map and reduce 
                 Key: MAPREDUCE-5941
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5941
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: mrv2
            Reporter: Gera Shegalov


JobCounters are currently organized counterintuitively.  We duplicate the same logical counter. For example, there is NUM_FAILED_MAPS and NUM_FAILED_REDUCES instead of NUM_FAILED_TASKS in map group and reduce group. 

As a consequence the counters are displayed in two lines in the UI instead of filling the map and reduce column in a single Counter table row.
