Andrew Purtell commented on HBASE-16296:
----------------------------------------
I will read the relevant code when back in front of a computer but my read of
this issue suggests this would be an allowable bug fix change in the next 0.98
minor.
> Reverse scan performance degrades when scanner cache size matches page filter

> 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]).
