Amareshwari Sriramadasu commented on MAPREDUCE-467:
---------------------------------------------------
Sorry for the late comment,
update statistics should use tip.machineWhereTaskRan(taskid) insteadof
status.getTaskTracker(). Then you may have to introduce a non-null check for
the lost tracker case.
> Collect information about number of tasks succeeded / total per time unit for
> a tasktracker.
