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 from which we received the acknowledgement from is still registered. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
