[jira] [Commented] (FLINK-12122) Spread out tasks evenly across all
available registered TaskManagers

Ben La Monica commented on FLINK-12122:
---------------------------------------
I am able to get even distribution as long as everything at the same parallelism, so that is what I'll do for now and will eagerly await your feature :).

> With Flip-6, we changed the default behaviour how slots are assigned to {{TaskManages}}. Instead of evenly spreading it out over all registered {{TaskManagers}}, we randomly pick slots from {{TaskManagers}} with a tendency to first fill up a TM before using another one. This is a regression wrt the pre Flip-6 code.
> I suggest to change the behaviour so that we try to evenly distribute slots across all available {{TaskManagers}} by considering how many of their slots are already allocated.
