             Summary: Column name map is broken 
                 Key: HIVE-6349

          Issue Type: Sub-task
            Reporter: Jitendra Nath Pandey

Following query results in exception at run time in vector mode.

explain select n_name from supplier_orc s join ( select n_name, n_nationkey from nation_orc
n join region_orc r on n.n_regionkey = r.r_regionkey and r.r_name = 'XYZ') n1 on s.s_nationkey
= n1.n_nationkey;

Here n_name is a string and all other fields are int.

The stack trace:
