-----------------------------------------------------------
It's complex now...if a FilterListWithAND has two sub filters A & B, and B has
a row-level global state (such as column offset...), after HBASE-18410, we
optimze the forward step to be maximum, so we consider the return code from
sub-filters at global level, which means that a cell may not be included the
sub-filter A, but we still need to pass the cell to sub-filter B for
calculating B' return code (for global return code purpose), finally B's
row-level global state messed up ...

> Project: HBase
> Issue Type: Bug
> Components: Filters
> Affects Versions: 1.4.4
> Reporter: Jerry He
> Assignee: Zheng Hu
> Priority: Major
> Attachments: debug.diff, debug.log, test-branch-1.4.patch
>
>
> 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.
