> When a reverse scan is done, the server seems to not know it's done when the 
> scanner cache size matches the number of rows in a PageFilter. See 
> PHOENIX-3121 for how this manifests itself. We have a standalone, pure HBase 
> API reproducer too that I'll attach (courtesy of [~churromorales] and 
> [~mujtabachohan]).
