>            Reporter: Pradeep Kamath
>            Assignee: Alan Gates
>             Fix For: types_branch
> JOIN should follow SQL semantics .i.e if the join key is a null or part of the join key
is null in the first table, it should not join with similar keys in the second table.
> Cogroup should coalesce all NULL key rows into one group.
