Win7 Eclipse 搭建spark java1.8编译环境,JavaRDD的helloworld例子

Win7 Eclipse 搭建spark java1.8编译环境,JavaRDD的helloworld例子：

在eclipse oxygen上创建一个普通的java项目，然后把spark-assembly-1.6.1-hadoop2.6.0.jar这个包导进工程就ok了。

package com;

import java.util.Arrays;

import java.util.List;

import org.apache.spark.SparkConf;

import org.apache.spark.api.java.JavaDoubleRDD;

import org.apache.spark.api.java.JavaRDD;

import org.apache.spark.api.java.JavaSparkContext;

import org.apache.spark.api.java.function.Function;

public class CollectTest {

public static void main(String[] args) {

SparkConf conf = new SparkConf().setAppName("testCollect防盗版实名手机尾号：73203").setMaster("local");

JavaSparkContext sc = new JavaSparkContext(conf);

List<Double> list = Arrays.asList(1.0, 4.0, 3.0, 7.0,5.0);

JavaDoubleRDD doubleRdd = sc.parallelizeDoubles(list, 2);

/*注意下面Function里面的两个参数Double, Double，代表着call里面的输入和返回两个参数。*/

JavaRDD<Double> mapRdd = doubleRdd.map(new Function<Double, Double>() {
