------------------------------------------------
bq. is the scenario you outline in TestFilterList? (
Haven't checked that. But some of the filter tests does not have @Test tag - so
even if the scenario is there may be they don't run. I have raised a JIRA to
add @Test tag for all the tests.
I will check the patch and see if there could be a possible bug as far as I can
see. +1 to fix FilterList behaviour consistency in 1.3+.

> 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
