-----------------------------------
Integrated in Hadoop-Mapreduce-0.23-Commit #425 (See
[https://builds.apache.org/job/Hadoop-Mapreduce-0.23-Commit/425/])
Merge -c 1235103 from trunk to branch-0.23 to fix MAPREDUCE-3681. Fixed
computation of queue's usedCapacity.

> Key: MAPREDUCE-3681
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3681
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2
> Affects Versions: 0.23.0
> Reporter: Thomas Graves
> Assignee: Arun C Murthy
> Priority: Critical

> MAPREDUCE-3681.patch

>
> In the Capacity scheduler if you configure the queues to be hierarchical
> where you have root -> parent queue -> leaf queue, the leaf queue doesn't
> calculate the used capacity properly. It seems to be using the entire cluster
> memory rather then its parents memory capacity.
> In updateResource in LeafQueue:
> setUsedCapacity(
> usedResources.getMemory() / (clusterResource.getMemory() * capacity));
> I think the clusterResource.getMemory() should be something like
> getParentsMemory().
