Subject [jira] [Updated] (YARN-8917) Absolute (maximum) capacity of level3+ queues is wrongly calculated for absolute resource
Date Wed, 14 Nov 2018 23:55:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-8917?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Wangda Tan updated YARN-8917:
-----------------------------
    Target Version/s: 3.2.1

> Absolute (maximum) capacity of level3+ queues is wrongly calculated for absolute resource
> -----------------------------------------------------------------------------------------

>          Components: capacityscheduler
>    Affects Versions: 3.2.1
>            Reporter: Tao Yang
>            Assignee: Tao Yang

> 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.
