Till Rohrmann commented on FLINK-8044:
--------------------------------------
Thanks for letting me know. We currently also follow the simple heuristic that
whenever you have a previous location, try to be scheduled to the same place
again. I think this should already help a lot with recovering.

> Project: Flink
> Issue Type: New Feature
> Components: Scheduler
> Affects Versions: 1.4.0
> Reporter: Sihua Zhou
> Priority: Major
>
> For local recovery we need a scheduler to satisfy both state locality and

> topologically, this can cause bad result if we allocate base on both state
> and input, so some revision for scheduler is necessary now.
