Ted Yu commented on HBASE-20565:
--------------------------------
I am a little curious about the following change:
{code}
filterList = new FilterList(Operator.MUST_PASS_ALL, filter4, filter5,
filter6);
- assertEquals(ReturnCode.SEEK_NEXT_USING_HINT, filterList.filterCell(kv1));
+ assertEquals(ReturnCode.NEXT_COL, filterList.filterCell(kv1));
{code}
Does this mean that the hint is not utilized with the fix ?

> When ColumnPaginationFilter is combined with ColumnRangeFilter, we may see
> incorrect result.
> Here is a simple example.
> One row with 10 columns c0, c1, c2, .., c9. I have a ColumnRangeFilter for
> range c2 to c9. Then I have a ColumnPaginationFilter with limit 5 and offset
> 0. FileterList is FilterList(Operator.MUST_PASS_ALL, ColumnRangeFilter,
> ColumnPaginationFilter).
> We expect 5 columns being returned. But in HBase 1.4 and after, 4 columns
> are returned.
> In 1.2.x, the correct 5 columns are returned.
