Derive PriorityClassName for shadow pod group from pod PriorityClassName

[Mateusz Litwin]

Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind bug
/kind feature

Implementation

It should be fairly simple few lines change in createShadowPodGroup() in pkg/scheduler/cache/util.go

Happy to make a PR.

that makes sense to me :)

BTW, did you try Volcano: http://github.com/volcano-sh/volcano ?

[Mateusz Litwin]

@k82cn Hi! I looked it up. Volcano seems like a more complicated solution. There are more custom resource definitions to learn and services to maintain. I want batch scheduling capabilities without forcing users to use specific frameworks or workflows, ideally enabling batch scheduling should be as simple specifying scheduler name plus some optional annotations in the pod template or controller.

oh, Volcano provide the same interface for scheduling part; it's up to you whether using job or not. One more feature is Queue, whose lifecycle is managed by queue controller :)
