--------------------------------------

Can you give us the schema for the two tables?

>             Project: Hive
>          Issue Type: Bug
>          Components: ORC, SQL
>    Affects Versions: 1.2.1
>         Environment: Hive 1.2.1 + Hadoop 2.6.2

> We have the scenario of ORC with ACID joining with TXT table and it can't retrieve that ID based row which should.
> Here is the HQL:
> select a.id a_id,b.id b_id from txtdb.order a, orcdb.order_cln b where a.id = b.id and b.id = '8a708a864faf8ef6014fb70426d62a67';
> Table txtdb.order is TXT format and orcdb.order_cln is ORC format. Both of tables have this ID based row. But the result is empty.
> Surprisingly, if I switch the position of TXT and ORC as follows,
> select a.id a_id,b.id b_id from orcdb.order_cln a, txtdb.order b where a.id = b.id and b.id = '8a708a864faf8ef6014fb70426d62a67';
> Then this ID based row returns correctly.,
