-------------------------------

             Summary: Remove SlotProvider from SchedulerNG
                 Key: FLINK-19922
                 URL: https://issues.apache.org/jira/browse/FLINK-19922
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Coordination
    Affects Versions: 1.12.0
            Reporter: Zhu Zhu
             Fix For: 1.12.0


SchedulerNG now uses ExecutionSlotAllocator to allocate slots. SlotProvider is no longer directly needed by SchedulerNG and ExecutionGraph. Currently a ThrowingSlotProvider is used as a SlotProvider placeholder in SchedulerNG and ExecutionGraph.
After legacy scheduling is removed in FLINK-19919, the placeholder for SlotProvider is not needed anymore and thus can be removed.
