capacity scheduler LeafQueues calculate used capacity wrong
-----------------------------------------------------------
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
Priority: Blocker
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().
