Allen Wittenauer resolved MAPREDUCE-1679.
-----------------------------------------
Resolution: Won't Fix
No one looks at Hadoop's documentation so this won't get fixed.
> capacity scheduler's user-limit documentation is not helpful
> ------------------------------------------------------------
>
> Key: MAPREDUCE-1679
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1679
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: contrib/capacity-sched
> Affects Versions: 0.20.2, 0.21.0, 0.22.0
> Reporter: Allen Wittenauer
> Priority: Trivial
>
> The example given for the user limit tunable doesn't actually show how that
> value comes into play. With 4 users, the Max() is 25 for both the user limit
> and the capacity limit (from my reading of the source). Either pushing the
> example to 5 users or raising the user limit to something higher than 25
> would help a great deal. Also, presenting this info in tabular format
> showing how the max() value is in play would also be great.
