spark读redis，JAVA版

SparkConf sparkConf = new SparkConf()
.setAppName(“MyApp”)
.setMaster(“local[*]”)
.set(“spark.redis.host”, “localhost”)
.set(“spark.redis.port”, “6379”);

RedisConfig redisConfig = RedisConfig.fromSparkConf(sparkConf);
ReadWriteConfig readWriteConfig = ReadWriteConfig.fromSparkConf(sparkConf);

JavaSparkContext jsc = new JavaSparkContext(sparkConf);
RedisContext redisContext = new RedisContext(jsc.sc());

JavaRDD<Tuple2<String, String>> rdd = jsc.parallelize(Arrays.asList(Tuple2.apply(“myKey”, “Hello”)));
int ttl = 0;

redisContext.toRedisKV(rdd.rdd(), ttl,redisConfig,readWriteConfig)
