Till Rohrmann commented on FLINK-13165:
---------------------------------------
Yes agreed. One needs to set the input dependency constraint to ALL. This issue
should simply make the behaviour of the {{SlotPoolImpl}} more predictable in
terms of semantics.
> Complete requested slots in request order

> When executing batch jobs with fewer slots than requested we should make sure
> that the slot requests are being completed in the order in which they were
> enqueued into the {{SlotPool}}. Otherwise we might risk that a consumer task
> gets deployed before a producer causing a resource deadlock situation.
