Nicholas Jiang commented on FLINK-18407:
----------------------------------------
[~trohrmann], do you mean that get pending request according to
requestIdOfAllocatedSlot maybe null? If the pending request is null, this would
cause the NPE.
> NPE in SlotPoolImpl.maybeRemapOrphanedAllocation if no pending request is
> registered
