> see HIVE-14589.
> Basic idea (spent about 7 minutes thinking about this based on RB comment ;)) 
> is to return locations for all slots to HostAffinitySplitLocationProvider, 
> the missing slots being inactive locations (based solely on the last slot 
> actually present). For the splits mapped to these locations, fall back via 
> different hash functions, or some sort of probing.
> This still doesn't handle all the cases, namely when the last slots are gone 
> (consistent hashing is supposed to be good for this?); however for that we'd 
> need more involved coordination between nodes or a central updater to 
> indicate the number of nodes
