Chesnay Schepler commented on FLINK-20605:
------------------------------------------

Yes, for 1 and 2 that was my plan as well.

For 3 I will first try to confirm whether it really is just a duplicate 
message; it could also be that the slot is marked as allocated for another job.

> DeclarativeSlotManager crashes if slot allocation notification is processed 
> after taskexecutor shutdown

> It is possible that a notification from a task executor about a slot being 
> allocated can be processed after that very task executor has unregistered 
> itself from the resource manager.
> As a result we run into an exception when trying to mark this slot as 
> allocated, because it no longer exists and a precondition catches this case.
> We could solve this by checking in 
> {{DeclarativeResourceManager#allocateSlot}} whether the task executor we 
> received the acknowledge from is still registered.
