Naveen Gangam commented on HIVE-10808:
--------------------------------------
This issue can be reproduced very consistently in Hive 0.13 (Havent tried hive
0.14) using the following reproducer.
{code}
create table test_part (a int) partitioned by (num int, part2 int);
alter table test_part add partition (num=201501, part2=0);
alter table test_part add partition (num=201501, part2=1);
alter table test_part add partition (num=201501, part2=2);
select num from test_part a inner join (select max (num) as dt from test_part
where num<201501) b on a.num=b.dt;
{code}
Its important that the table/partition has no data in it.
The stacktrace appears in the hive.log. I have verfied that the fix in the
proposed patch resolves the issue. In Hive 1.1+, I cannot reproduce this issue.
Some other fix is either masking the issue or bypassing it.
Inspecting the code, I think the issue is a bit obvious. Would this be enough
to have this committed? Thanks
