--------------------------------
Summary: Move application-specific container allocation logic from
LeafQueue to FiCaSchedulerApp
Key: YARN-3026
URL: https://issues.apache.org/jira/browse/YARN-3026
Project: Hadoop YARN
Issue Type: Task
Components: capacityscheduler
Reporter: Wangda Tan
Assignee: Wangda Tan
Have a discussion with [~vinodkv] and [~jianhe]:
In existing Capacity Scheduler, all allocation logics of and under LeafQueue
are located in LeafQueue.java in implementation. To make a cleaner scope of
LeafQueue, we'd better move some of them to FiCaSchedulerApp.
Ideal scope of LeafQueue should be: when a LeafQueue receives some resources
from ParentQueue (like 15% of cluster resource), and it distributes resources
to children apps, and it should be agnostic to internal logic of children apps
(like delayed-scheduling, etc.). IAW, LeafQueue shouldn't decide how
application allocating container from given resources.
