----------------------------------
Hi, [~openinx] Thanks for taking a look!
i did a little more testing with the test patch. Here is what I got:
Branch 1.4:
-------------------------------------------
ColumnRangeFilter StringRange(“1”, true, "9", false), ColumnPaginationFilter(5,
0)
Result: 0, 1, 2, 3, 4
StringRange(“1”, true, "9", false), ColumnPaginationFilter(5, 0)
Result: 1, 2, 3, 4
StringRange(“3”, true, "9", false), ColumnPaginationFilter(5, 0)
Result: 3, 4, 5, 6
StringRange(“0”, true, "9", false), ColumnPaginationFilter(5, 1)
Result: 1, 2, 3, 4, 5
StringRange(“1”, true, "9", false), ColumnPaginationFilter(5, 1)
Result: 1, 2, 3, 4 , 5
StringRange(“3”, true, "9", false), ColumnPaginationFilter(5, 1)
Result: 3, 4, 5, 6, 7
Branch 1.2
-------------------------------------------
ColumnRangeFilter StringRange(“0”, true, "9", false), ColumnPaginationFilter(5,
0)
Result: 0, 1, 2, 3, 4
StringRange(“1”, true, "9", false), ColumnPaginationFilter(5, 0)
Result: 1, 2, 3, 4, 5
StringRange(“3”, true, "9", false), ColumnPaginationFilter(5, 0)
Result: 3, 4, 5, 6, 7
StringRange(“0”, true, "9", false), ColumnPaginationFilter(5, 1)
Result: 1, 2, 3, 4, 5
StringRange(“1”, true, "9", false), ColumnPaginationFilter(5, 1)
Result: 2, 3, 4 , 5, 6
StringRange(“3”, true, "9", false), ColumnPaginationFilter(5, 1)
Result: 4, 5, 6, 7, 8

> Key: HBASE-20565
> URL: https://issues.apache.org/jira/browse/HBASE-20565
> 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.
