--------------------------------
Hi, [~rohithsharma], I can't reproduce this failure on trunk branch in my local
environment, according to the standard output, the assignment which should
allocate a container was broke for unknown reason after checking node, debug
info is not enough to locate the cause. Moreover, this patch only affect the
capacity shown in WebUI or REST results, won't affect the scheduling process.
So I think they are not related.
> Absolute (maximum) capacity of level3+ queues is wrongly calculated for
> absolute resource

> Key: YARN-8917
> URL: https://issues.apache.org/jira/browse/YARN-8917
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Affects Versions: 3.2.1
> Reporter: Tao Yang
> Assignee: Tao Yang
> Priority: Critical
> Attachments: YARN-8917.001.patch, YARN-8917.002.patch

> Absolute capacity should be equal to multiply capacity by parent-queue's
> absolute-capacity,
> but currently it's calculated as dividing capacity by parent-queue's
> absolute-capacity.
> Calculation for absolute-maximum-capacity has the same problem.
> For example:
> root.a capacity=0.4 maximum-capacity=0.8
> root.a.a1 capacity=0.5 maximum-capacity=0.6
> Absolute capacity of root.a.a1 should be 0.2 but is wrongly calculated as 1.25
> Absolute maximum capacity of root.a.a1 should be 0.48 but is wrongly
> calculated as 0.75
> Moreover:
> {{childQueue.getQueueCapacities().getCapacity()}} should be changed to
> {{childQueue.getQueueCapacities().getCapacity(label)}} to avoid getting wrong
> capacity from default partition when calculating for a non-default partition.
