Andrew Purtell commented on HBASE-16296:
----------------------------------------
I applied Ted's change to master and ran all scanner and filter tests locally
and they pass except for TestPartialResultsFromClientSide, which fails anyway
with REEs complaining about socket timeout after region move (not good -
separate issue). Checking branch-1 now.
> Reverse scan performance degrades when using filter lists

> 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]).
