      Description

      0.21 mapreduce.Reducer introduced a blind cast to ReduceContext.ValueIterator. There should an instanceof check around this block to ensure we don't throw a CastClassException:

             // If a back up store is used, reset it
            ((ReduceContext.ValueIterator)
                (context.getValues().iterator())).resetBackupStore();

        Attached is a patch which wraps the cast in an instanceof thereby avoiding a possible cast class exception.
