Preston Koprivica commented on HBASE-4394:
------------------------------------------
Is there any reason that hinting/seeking can't be applied to MUST_PASS_ONE
filter lists?
It looks like this issue has added support for generating a hint for a
MUST_PASS_ONE filterlist (by retaining the minimum hint of all the internal
filters), but it doesn't look like the filterlist will ever return
SEEK_USING_NEXT_HINT return code on #filterKeyValue(..) for MUST_PASS_ONE
filters [1].
