Zheng Hu commented on HBASE-18368:
----------------------------------
bq. How about we rename NEXT_ROW to NEXT_FAMILY directly?
I would like to separate them into NEXT_ROW & NEXT_FAMILY. for
ScanQueryMatcher , they are the same logic, but for filter, their meanings are
different, the former means skip to the next row, and the later means skip to
the next family. besides, for FilterList , their logic are different
now.
> FilterList with multiple FamilyFilters concatenated by OR does not work.

> Scan gives back incomplete list if multiple filters are combined with OR /
> MUST_PASS_ONE.
> Using 2 FamilyFilters in a FilterList using MUST_PASS_ONE operator will give
> back results for only the first Filter.
