You need to cancel and resubmit the patch. I just did that for your
patch.

> When an UDF returns a map and the outputSchema method is not
overridden, Pig does not figure out the data type. As a result, the type
is set to unknown resulting in run time failure. An example script and
UDF follow
> {code}
> public class mapUDF extends EvalFunc<Map<Object, Object>> {
>     @Override
>     public Map<Object, Object> exec(Tuple input) throws IOException {
>             return new HashMap<Object, Object>();
>     }
> //Note that the outputSchema method is commented out
> /*
>     @Override
>     public Schema outputSchema(Schema input) {
>         try {
>             return new Schema(new Schema.FieldSchema(null, null,
DataType.MAP));
>         } catch (FrontendException e) {
>             return null;
>         }
>     }
