> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 3.1.0
> Reporter: Naveen Gangam
> Assignee: Mustafa Iman
> Priority: Major
> Labels: pull-request-available
> Attachments: HIVE-23435.1.patch, HIVE-23435.patch, HIVE-23435.patch,

> Full Outer join result has missing rows. Appears to be a bug with the full
> outer join logic. Expected output is receiving when we do a left and right
> outer join.
> Reproducible steps are mentioned below.
> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
> SUPPORT ANALYSIS
> Steps to Reproduce:
> 1. Create a table and insert data:
> create table x (z char(5), x int, y int);
> insert into x values ('one', 1, 50),
> ('two', 2, 30),
> ('three', 3, 30),
> ('four', 4, 60),
> ('five', 5, 70),
> ('six', 6, 80);
> 2. Try full outer with the below command. The result is incomplete, it is
> missing the row:
> NULL NULL NULL three 3 30.0
> Full Outer Join:
> select x1.`z`, x1.`x`, x1.`y`, x2.`z`,
> x2.`x`, x2.`y`
> from `x` x1 full outer join
> `x` x2 on (x1.`x` > 3) and (x2.`x` < 4) and (x1.`x` =
> x2.`x`);
> Result:
> ----------------------------------+
> x1.z x1.x x1.y x2.z x2.x x2.y
> ----------------------------------+
> one 1 50 NULL NULL NULL
> NULL NULL NULL one 1 50
> two 2 30 NULL NULL NULL
> NULL NULL NULL two 2 30
> three 3 30 NULL NULL NULL
> four 4 60 NULL NULL NULL
> NULL NULL NULL four 4 60
> five 5 70 NULL NULL NULL
> NULL NULL NULL five 5 70
> six 6 80 NULL NULL NULL
> NULL NULL NULL six 6 80
> ----------------------------------+
> 3. Expected output is coming when we use left/right join + union:
> select x1.`z`, x1.`x`, x1.`y`, x2.`z`,
> x2.`x`, x2.`y`
> from `x` x1 left outer join
> `x` x2 on (x1.`x` > 3) and (x2.`x` < 4) and (x1.`x` =
> x2.`x`)
> union
> select x1.`z`, x1.`x`, x1.`y`, x2.`z`,
> x2.`x`, x2.`y`
> from `x` x1 right outer join
> `x` x2 on (x1.`x` > 3) and (x2.`x` < 4) and (x1.`x` =
> x2.`x`);
> Result:
> ------------------------------------+
> z x y _col3 _col4 _col5
> ------------------------------------+
> NULL NULL NULL five 5 70
> NULL NULL NULL four 4 60
> NULL NULL NULL one 1 50
> four 4 60 NULL NULL NULL
> one 1 50 NULL NULL NULL
> six 6 80 NULL NULL NULL
> three 3 30 NULL NULL NULL
> two 2 30 NULL NULL NULL
> NULL NULL NULL six 6 80
> NULL NULL NULL three 3 30
> NULL NULL NULL two 2 30
> five 5 70 NULL NULL NULL
> ------------------------------------+
