> 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]).
