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

             Summary: Support unqualified column references in Joining conditions
                 Key: HIVE-6393
                 URL: https://issues.apache.org/jira/browse/HIVE-6393
             Project: Hive
          Issue Type: Improvement
            Reporter: Harish Butani


Support queries of the form:
{noformat}
create table r1(a int);
create table r2(b);
select a, b
from r1 join r2 on a = b
{noformat}
This becomes more useful in old style syntax:
{noformat}
select a, b
from r1, r2
where a = b
{noformat}
