public void forwardUDTFOutput(Object o) throws HiveException {
    // Since the output of the UDTF is a struct, we can just forward that
    forward(o, outputObjInspector);
  }
forwardUDTFOutput is typically called indirectly by the GenericUDTF when
the GenericUDTF has generated output rows that should be passed on to the
next operator(s) in the DAG.
