Win7 Eclipse 搭建spark java1.8编译环境,JavaRDD的helloworld例子：马克-to-win @ 马克java社区：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马克-to-win @ 马克java社区：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>() { public Double call(Double in) throws Exception { return in + 2; } }); List<Double> douList = mapRdd.collect(); for (Double d : douList) { System.out.println("d:" + d); } }} 更多请看下节：https://blog.csdn.net/qq_44596980/article/details/93384494
