Devaraj Das commented on MAPREDUCE-467:
---------------------------------------
Looks fine to me. The UI can be improved. For example, the metrics could be
printed out in a sorted fashion by number of succeeded tasks. The UI could also
have percentage information instead of absolute numbers for the succeeded
tasks' metrics.
> Collect information about number of tasks succeeded / total per time unit for
> a tasktracker.
