Márton Balassi commented on FLINK-31974:
----------------------------------------
In the specific case I much prefer the behaviour exhibited by 1.16.1. Resource
quota not being available changes dynamically, if the JobManager kept retrying
(ideally with a backoff) it is not unreasonable to expect that eventually it
could succeed in most real-world scenarios. Adding some guardrails around this
(if a minimum parallelism is not satisfied fail instead, if a max timeout is
reached fail etc) to avoid ending up with many small jobs competing for
insufficient resources and wasting capacity would be acceptable to me, but
outright failing on the first try is more a bug than a feature imho. :)
