Damien Carol commented on HIVE-10902:
-------------------------------------

Tested on master with and without data. It works.
{code:sql}
create table t1(id string);
create table t2(id string);
select t1.INPUT__FILE__NAME  
from t1 join t2 on t1.id = t2.id;
{code}
With data :
{code:sql}
insert into t1 values("test1");
insert into t2 values("test1");
{code}
{noformat}
0: jdbc:hive2://nc-h07:10000/> select t1.INPUT__FILE__NAME
0: jdbc:hive2://nc-h07:10000/> from t1 join t2 on t1.id = t2.id;

>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 0.14.0
>         Environment: cloudera 5.3.3, but happening also in hdp 2.2 and also on clean
installs on linux.  
>            Reporter: Rani Yaroshinsky
>
> did the following:
> {code:sql}
> create table t1(id string);
> create table t2(id string);
> select t1.INPUT__FILE__NAME  
> from t1 join t2 on t1.id = t2.id;
> {code}
> {noformat}
> fails on: Execution failed with exit status: 2
> {noformat}
> notice this happens also on self joins:select t1_1.INPUT__FILE__NAME  from t1 t1_1 join
t1 t1_2 on t1_1.id = t1_2.id
> [HIVE-8186] is related to self joins and said the issue has been resolved, but this does
not seem to be the case.
> thanks for your help.
