Spark编程环境搭建(基于Intellij IDEA的Ultimate版本)
为什么,我要在这里提出要用Ultimate版本。
IDEA Community(社区版)再谈之无奈之下还是去安装旗舰版
IntelliJ IDEA的黑白色背景切换(Ultimate和Community版本皆通用)
使用 IntelliJ IDEA 导入 Spark 最新源码及编译 Spark 源代码
IDEA里如何多种方式打jar包,然后上传到集群
IntelliJ IDEA(Community版本)的下载、安装和WordCount的初步使用(本地模式和集群模式)
IntelliJ IDEA(Ultimate版本)的下载、安装和WordCount的初步使用(本地模式和集群模式)
基于Intellij IDEA搭建Spark开发环境搭——参考文档
参考文档http://spark.apache.org/docs/latest/programming-guide.html
操作步骤
a)创建maven 项目
b)引入依赖(Spark 依赖、打包插件等等)
基于Intellij IDEA搭建Spark开发环境—maven vs sbt
a)哪个熟悉用哪个
b)Maven也可以构建scala项目
基于Intellij IDEA搭建Spark开发环境搭—maven构建scala项目
参考文档http://docs.scala-lang.org/tutorials/scala-with-maven.html
操作步骤
a) 用maven构建scala项目(基于net.alchim31.maven:scala-archetype-simple)
spark-helloworld
E:\Code\IntelliJIDEAUltimateVersionCode\spark-helloworld
因为,我本地的scala版本是2.10.5
其实,这个就是windows里的cmd终端,只是IDEA它把这个cmd终端集成到这了。
mvn clean package
这只是做个测试而已。
b)pom.xml引入依赖(spark依赖、打包插件等等)
注意:scala与java版本的兼容性

为了养成,开发规范。
默认,创建是没有生效的,比如做如下,才能生效。
同样,对于下面的单元测试,也是一样
默认,也是没有生效的。
必须做如下的动作,才能生效。
开发第一个Spark程序
a) 第一个Scala版本的spark程序
package com.dajiangtai.test import org.apache.spark.{SparkConf, SparkContext} /** * Created by lifei on 2016-6-19. */ object MyWordCout { def main(args: Array[String]): Unit = { //参数检查 if (args.length < 2) { System.err.println("Usage: MyWordCout <input> <output> ") System.exit(1) } //获取参数 val input=args(0) val output=args(1) //创建scala版本的SparkContext val conf=new SparkConf().setAppName("myWordCount") val sc=new SparkContext(conf) //读取数据 val lines=sc.textFile(input) //进行相关计算 val resultRdd=lines.flatMap(_.split(" ")).map((_,1)).reduceByKey(_+_) //保存结果 resultRdd.saveAsTextFile(output) sc.stop() }
b) 第一个Java版本的spark程序
package com.dajiangtai.test; import org.apache.spark.SparkConf; import org.apache.spark.api.java.JavaPairRDD; import org.apache.spark.api.java.JavaRDD; import org.apache.spark.api.java.JavaSparkContext; import org.apache.spark.api.java.function.FlatMapFunction; import org.apache.spark.api.java.function.Function2; import org.apache.spark.api.java.function.PairFunction; import scala.Tuple2; import java.util.Arrays; /** * Created by lifei on 2016-6-19. */ public class MyJavaWordCount { public static void main(String[] args) { //参数检查 if(args.length<2){ System.err.println("Usage: MyJavaWordCount <input> <output> "); System.exit(1); } //获取参数 String input=args[0]; String output=args[1]; //创建java版本的SparkContext SparkConf conf=new SparkConf().setAppName("MyJavaWordCount"); JavaSparkContext sc=new JavaSparkContext(conf); //读取数据 JavaRDD inputRdd=sc.textFile(input); //进行相关计算 JavaRDD words=inputRdd.flatMap(new FlatMapFunction() { public Iterable call(String line) throws Exception { return Arrays.asList(line.split(" ")); } }); JavaPairRDD result=words.mapToPair(new PairFunction() { public Tuple2 call(String word) throws Exception { return new Tuple2(word,1); } }).reduceByKey(new Function2() { public Integer call(Integer x, Integer y) throws Exception { return x+y; } }); //保存结果 result.saveAsTextFile(output); //关闭sc sc.stop(); } }
运行自己开发第一个Spark程序
Spark maven 项目打包
mvn package
提交Spark 集群运行
a) 提交Scala版本的Wordcount
bin/spark-submit --class com.zhouls.test.MyWordCount ~/testspark/test-spark-1.0.SNAPSHOT.jar ~/testspark/words.txt ~/testspark/result
b) 提交Java版本的Wordcount
bin/spark-submit --class com.zhouls.test.MyJavaWordCount ~/testspark/test-spark-1.0.SNAPSHOT.jar ~/testspark/words.txt ~/testspark/result1
成功!
