> When we are trying to use order-preserving sorted union:
> ....
> We got the following schema, where the type of 'source_table' is (null) with no column
name:
> {id: chararray,name: chararray,context: chararray,writer: chararray,rev: chararray,schema:
chararray,(null)}
> I tried to project the 'source_table' field but failed:
> B = FOREACH A GENERATE id, $6; 
> DUMP B;
> But then we got exception org.apache.pig.impl.logicalLayer.FrontendException: ERROR 1066:
Unable to open iterator for alias B.
> Can you guys please let us know how to access this column? Or is the symptom described
above is a bug?
