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.
