[jira] [Created] (YUNIKORN-232) Send essential container scheduling state to shim as a supplementary info for autoscaling

Weiwei Yang created YUNIKORN-232:
------------------------------------

             Summary: Send essential container scheduling state to shim as a supplementary info for autoscaling 
                 Key: YUNIKORN-232
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-232
             Project: Apache YuniKorn
          Issue Type: Improvement
          Components: core - scheduler, scheduler-interface, shim - kubernetes
            Reporter: Weiwei Yang
            Assignee: Weiwei Yang


On cloud env, when partition resource (physical nodes) resource is not enough, but YK still has enough capacity, we do want to trigger auto-scaling; but if queue capacity is exceeded, we do not want to trigger auto-scaling.

Introduce a scheduler plugin to send some supplementary info to the shim to handle this accordingly.
