Spark将JavaDStream方法转换为JavaPairDStream方法

我在Spark流媒体代码中有这个函数，它将推特拆分为单个单词

JavaDStream<String> words = statuses
                .flatMap(new FlatMapFunction<String, String>() {
                    public Iterable<String> call(String in) {
                        return Arrays.asList(in.split(" "));
                    }
                });

使用以下命令获取功能

JavaPairDStream<String, String> locationspairRdd=OutStreamRDD.mapToPair(new PairFunction<String, String, String>() {
    public Tuple2<String, String> call(String arg0) throws Exception {
        return null;
    }
});

JavaPairDStream<String, String> locationspairRdd=OutStreamRDD.mapToPair(new PairFunction<String, String, String>() {
    public Tuple2<String, String> call(String arg0) throws Exception {
        return null;
    }
});
