> Column pruner for union could fail if one source of union have the schema and
> the other does not have schema. For example, the following script fail:
> {code}
> a = load '1.txt' as (a0, a1, a2);
> b = foreach a generate a0;
> c = load '2.txt';
> d = foreach c generate $0;
> e = union b, d;
> dump e;
> {code}
> However, this issue is in trunk only and is not applicable to 0.6 branch.
