Alexander Pivovarov commented on HIVE-1534:
-------------------------------------------
to reproduce:
hive> create table tt1 (c1 int);
hive> create table tt2 (c1 int);
$ vi tt1
1
2
3
4
$ vi tt2
1
2
8
9
$ hadoop fs -put tt1 /user/hive/warehouse/tt1/
$ hadoop fs -put tt2 /user/hive/warehouse/tt2/
wrong result:
hive> select * from tt1 left outer join tt2 on (tt1.c1 = tt2.c1 and tt1.c1 <=
2);
1 1
2 2
3 NULL
4 NULL
correct result:
select * from tt1 left outer join tt2 on (tt1.c1 = tt2.c1) where tt1.c1 <= 2;
1 1
2 2
