HPL/SQL does not support table aliases on column names in loops

HPL/SQL does not support table aliases on column names in cursor loops where as the same works in Oracle's PL/SQL.

This works in Oracle:

CREATE OR replace PROCEDURE test2
AS
BEGIN
FOR rec IN (select tab.a from test tab) LOOP
dbms_output.put_line(rec.a);
END LOOP;
END;
SQL> call test2();
one
two

This does not work in Hive -
ERROR : Unhandled exception in HPL/SQL
No other errors are shown

Without alias, it works in Hive:

BEGIN
FOR rec IN (select a from test tab) LOOP
dbms_output.put_line(rec.a);
END LOOP;
END;
