      Description

      Currently even if pig.schematuple is set to false which is the default, the usage of TupleToMapKey and TuplesToSchemaTupleList instead of plain HashMap<Object, ArrayList<Tuple>> costs a lot of memory. Also key is currently converted to a tuple which is unnecessary. Detail see PIG-4874
