>    Affects Versions: 3.0.0
>            Reporter: Gopal V

>
> Left & Right outer joins without keys are valid in SQL and they have 
> different semantics from cross-products
> {code}
> create temporary table foo(x int) stored as orc;
> insert into foo values(1),(2);
> create temporary table bar(y int) stored as orc;
> select count(*) from bar right outer join foo; -- = 2
> select count(*) from bar, foo; -- = 0 
> {code}
> canSpecializeMapJoin should bail on these cases.
