>                 URL: https://issues.apache.org/jira/browse/HIVE-10792
>             Project: Hive
>          Issue Type: Bug
>          Components: File Formats, Query Processor
>    Affects Versions: 0.13.0, 0.14.0, 0.13.1, 1.0.0, 1.2.0, 1.1.0
>            Reporter: Dayue Gao
>            Assignee: Dayue Gao
>            Priority: Critical
>             Fix For: 1.2.1
>
>         Attachments: HIVE-10792.1.patch, HIVE-10792.test.sql
>
>
> Here's the steps to reproduce the bug.
> First of all, prepare a simple ORC table with one row
> {code}
> create table test_orc (c0 int, c1 int) stored as ORC;
> {code}
> Table: test_orc
> ||c0||c1||
> |0|1|
> The following SQL gets empty result which is not expected
> {code}
> select * from test_orc t1
> union all
> select * from test_orc t2
> where t2.c0 = 1
> {code}
> Self join is also broken
> {code}
> set hive.auto.convert.join=false; -- force common join
> select * from test_orc t1
> left outer join test_orc t2 on (t1.c0=t2.c0 and t2.c1=0);
> {code}
> It gets empty result while the expected answer is
> ||t1.c0||t1.c1||t2.c0||t2.c1||
> |0|1|NULL|NULL|
> In these cases, we pushdown predicates into OrcInputFormat. As a result, TableScanOperator
for "t1" can't receive its rows.
