>
> 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.
