> Key: PIG-3083

> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Jonathan Coveney
> Labels: PIG-3078
> Fix For: 0.14.0

> This is basically a more refined approach than PIG-3078, but it is also more
> work. That JIRA is more of a stopgap until we do something like this.
> The idea would be to support something like the following:
> a = load 'a' as (x,y,z);
> b = load 'b' as (x,y,z);
> c = join a by x, b by x;
> d = foreach c generate a::*;
> Obviously this is useful for any case where you have relations with columns
> with various prefixes.
