---------------------------------------
I think this makes sense, it's most likely just a miss. I'll take a look.
Thanks for the report.

> Key: FLINK-36201
> URL: https://issues.apache.org/jira/browse/FLINK-36201
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Reporter: Rui Fan
> Priority: Major
>
> SlotSharingSlotAllocator created the StateLocalitySlotAssigner[1] instead of
> DefaultSlotAssigner whenever failover happens.
> I'm curious why we use StateLocalitySlotAssigner when local recovery is
> disable.
> As I understand, the local recovery doesn't take effect if flink doesn't
> backup state on the TM local disk. So StateLocalitySlotAssigner should be
> only used when local recovery is enabled.
