> The steps are the following(copied from Stephan's comments in [5931|https://github.com/apache/flink/pull/5931]):
> - JobMaster / SlotPool requests a slot (AllocationID) from the ResourceManager
> - ResourceManager starts a container with a TaskManager
> - TaskManager registers at ResourceManager, which tells the TaskManager to push a slot
to the JobManager.
> - TaskManager container is killed
> - The ResourceManager does not queue back the slot requests (AllocationIDs) that it sent
to the previous TaskManager, so the requests are lost and need to time out before another
attempt is tried.
