Zilong Zhu commented on YARN-11146:
-----------------------------------
I think CapacityConfigType of 0 resource leafqueue should follow its
parentqueue.
> Can't create 0 resources leafqueue in absolute mode

> Issue Type: Bug
> Components: capacityscheduler
> Reporter: Zilong Zhu

> I can't create 0 resources leafqueue ([memory=0,vcores=0]) in absoulte mode.
> For example:
> root.prod = [memory=2048,vcores=2]
> root.prod.prod_default = [memory=0,vcores=0]
> I got Exception:
> {code:java}
> refreshQueues: java.io.IOException: Failed to re-init queues : Parent queue
> 'prod' and child queue 'prod_default' should use either percentage based
> capacity configuration or absolute resource together.
