Subject Re: Non-collocated distributed SQL Joins across caches over separate cluster groups

Yes, this can happen if caches were created on different versions of
topology, because FairAffinityFunction is stateful and requires previous
affinity assignment state.

Generally, this can be fixed by introducing cache groups that use the same
affinity and use this shared state across all caches.
