Gunther Hagleitner commented on HIVE-10379:
-------------------------------------------
Doesn't happen in trunk any more. Might be HIVE-8888.
(the patch file only contains the test case, if you run against trunk it'll
give same result.)
> Wrong result when executing with tez

> I do a left join with a lateral view outer , too many row are generated with

> in map reduce , i have 125 rows , in tez 132 .....
> Example :
> {noformat}
> drop table foo ;
> create table foo ( dummyfoo int ) ;
> insert into table foo select count(*) from foo ;
> select count(*) as cnt from (
> select a.val,p.code from
> ( select cast((((one*5)+two)*5+three) as int) as val
> from foo
> lateral view outer
> explode(split("0,1,2,3,4",",")) tbl_1 as one
> lateral view outer
> explode(split("0,1,2,3,4",",")) tbl_2 as two
> lateral view outer
> explode(split("0,1,2,3,4",",")) tbl_3 as three ) as a
> left join
> ( select dummyfoo as code from foo ) p on p.code=a.val
