> Key: FLINK-14314
> URL: https://issues.apache.org/jira/browse/FLINK-14314
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Affects Versions: 1.10.0
> Reporter: Zhu Zhu
> Assignee: Zhu Zhu
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.10.0
>
>
> With FLINK-14058, it is assumed that a shared slot should be large enough to
> be used by one instance of each JobVertex in the group simultaneously.
> To support it, a shared slot resources should be the sum of all JobVertex
> resources in the group.
> Here's the concrete proposal:
> 1. Add a physicalSlotResourceProfile in SlotProfile. If the task is not in a
> shared slot, it is the task resource profile. Otherwise it is the slot
> sharing group resource profile. It should be used for physical slot
> allocation. Rename previous ResourceProfile to be taskResourceProfile for
> logical slot allocation.
> 2. SharedSlotOversubscribedException and its handling can be removed,
> including part of the children slots releasing and re-allocating. This is
> because partial fulfillment should not happen anymore with #1. A simple
> sanity check can be kept for oversubscribing.
