Ravi Gummadi commented on MAPREDUCE-2264:
-----------------------------------------
Is this an issue at job level progress only ? Are task progress percentages for
all tasks under 100% ? If a particular task's progress is shown as > 100%,
please provide the info of which phase that task is in when you see progress >
100%.
> Job status exceeds 100% in some cases

> Key: MAPREDUCE-2264
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-2264
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: jobtracker
> Reporter: Adam Kramer
>
> I'm looking now at my jobtracker's list of running reduce tasks. One of them
> is 120.05% complete, the other is 107.28% complete.
> I understand that these numbers are estimates, but there is no case in which
> an estimate of 100% for a non-complete task is better than an estimate of
> 99.99%, nor is there any case in which an estimate greater than 100% is valid.
> I suggest that whatever logic is computing these set 99.99% as a hard maximum.
