Cristina L. Abad commented on PIG-2743:
---------------------------------------

I would also find it helpful if the rank ends up in position $0. Does anybody think this would
have any disadvantages?

> For the rank operator, I was considering the following schema:
> E.g.
> A = load 'data' as (x:int,y:chararray,z:int,rz:chararray);
> C = rank A by x;
> So the output schema could be: 
> C: {x: int,y: chararray,z: int,rz: chararray,A::rank: int}
> In general 
> {<schema_of_working_alias>,<alias>::rank#int}
