counters: want rates and averages, and phase-level sums
-------------------------------------------------------

                 Key: HADOOP-1038
                 URL: https://issues.apache.org/jira/browse/HADOOP-1038
             Project: Hadoop
          Issue Type: New Feature
          Components: mapred
            Reporter: Doug Cutting


It would be nice if the web ui displayed, for each counter, not just its total, but also its
rate (counts/second).  Also, for job-level counts, per-task averages should be displayed,
of both total and rate.  Ideally we could also include phase-level counts (map versus reduce).
 Thus we could display, e.g., average map task input bytes/second for a job.
