> Hive Query Produces Wrong Result: PPD
> -------------------------------------

> Key: HIVE-10695
> URL: https://issues.apache.org/jira/browse/HIVE-10695
> Project: Hive
> Issue Type: Bug
> Reporter: Laljo John Pullokkaran
> Assignee: Laljo John Pullokkaran

> Following query produces wrong result:
> select * from t1 s left outer join (select key, value from t1) f on
> s.key=f.key and s.value=f.value left outer join (select key, value from
> t1) c on s.key=c.key where f.key is null;
> This is due to PPD getting confused between qualified col name & non
> qualified.
> In many places in code column info doesn't include table alias which leads to
> PPD problem.
> This is fixed in trunk as part of HIVE-9327
> https://issues.apache.org/jira/browse/HIVE-9327
