Ted Yu commented on HBASE-20565:
--------------------------------
I ran the new test with ColumnPaginationFilter placed first in branch-1.3 where
there is no HBASE-18410 :
{code}
TestColumnRangeFilterWithColumnPaginationFilter(org.apache.hadoop.hbase.filter.TestColumnRangeFilter)
Time elapsed: 1.679 sec <<< FAILURE!
java.lang.AssertionError: expected:<5> but was:<4>
at
org.apache.hadoop.hbase.filter.TestColumnRangeFilter.TestColumnRangeFilterWithColumnPaginationFilter(TestColumnRangeFilter.java:278)
{code}
So the patch here is good by me.
> ColumnRangeFilter combined with ColumnPaginationFilter can produce incorrect
> result since 1.4

> 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.
