    Description

      To reproduce, please run the following query-

      b = FOREACH a GENERATE (map[])udfs.empty_dict();
      DUMP b;
      

      where empty_dict() is a Python udf-

      @outputSchema("map_out: []")
      def empty_dict():
          return {}
      

      This returns ([]) in jython while ([null#]) in streaming_python.
