Arun Suresh commented on YARN-6022:
-----------------------------------
So, looks like the original class was created to unify Update requests and new
Resource Request. So I think we should capture that in the new class.
Given that the Scheduler deals with resources as requests and returns
containers as response, I was thinking it should have atleast these 3 fields:
# Resource capability
# ContainerId containerToUpdate (defaults to null)
# int numContainers (if containerToUpdate != null, this will be 1)
> Revert changes of AbstractResourceRequest

> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Wangda Tan
> Priority: Blocker
>
> YARN-5774 added AbstractResourceRequest to make easier internal scheduler
> change, this is not a correct approach: For example, with this change, we
> need to make AbstractResourceRequest to be public/stable. And end users can
> use it like:
> {code}
> AbstractResourceRequest request = ...
> request.setCapability(...)
> {code}
> But AbstractResourceRequest should not be visible by application at all.
> We need to revert it from branch-2.8 / branch-2 / trunk.
