> 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]).
