Issue Type: Improvement (was: Bug)
> type checking with order-by following user-defined function
> -----------------------------------------------------------
>
> Key: PIG-549
> URL: https://issues.apache.org/jira/browse/PIG-549
> Project: Pig
> Issue Type: Improvement
> Affects Versions: types_branch
> Environment: type checker fails here:
> A = load ...;
> B = foreach A generate UDF1(*), UDF2();
> C = order B by $1;
> where UDF2() is of type EvalFunc<Integer>.
> I tried all sorts of things, including overriding outputSchema() of the UDF to specify Integer, and also adding "as x : int" to the foreach command -- in all cases I get the same error.
> Reporter: Christopher Olston
> Fix For: types_branch
