今日目标：sortByKey

今日总结：

 new PairFunction<Tuple2<Integer,String>, String, Integer>() {

                                    private static final long serialVersionUID = 7017380215451671038L;

                                    @Override
                                    public Tuple2<String, Integer> call(Tuple2<Integer, String> tuple)
                                            throws Exception {

                                        return new Tuple2<String, Integer>(tuple._2, tuple._1);
                                    }
                                });

                            return sortRDD;
                        }
                    });
        
        // print result
        ResultSortDStream.print();
        
        jssc.start();
        
        jssc.awaitTermination();
        
        jssc.close();
        
    }
}
