创建RDD的方式

创建RDD的方法：

JavaRDD<String> lines = sc.textFile("hdfs://spark1:9000/spark.txt");

 

JavaRDD<String> lines = sc.textFile("C://Users//Administrator//Desktop//spark.txt");

 

List<Integer> numbers = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);

JavaRDD<Integer> numberRDD = sc.parallelize(numbers);
