使用Intellij构建spark源码阅读环境

步骤1：

下载spark-源码，这里以spark1.3为例。
http://spark.apache.org/downloads.html


2.下载编译后的spark源码，这里下载根据Hadoop2.3版本编译的。



3.使用Intellij新建scala工程（使用scala编写spark application，也可以新建java工程）



5.配置项目scala版本

6.导入spark依赖版-spark-assembly-1.3.0-hadoop2.4.0.jar



导入路径为：

FIle->ProjectStructure->project Settings->Libraries->+java->选择spark-assembly-1.3.0-hadoop2.4.0.jar。

7.导入spark-源码



点加号，选择spark1.3编译前源码，点确认。



8.新建spark-scala-hello-world项目，代码如下：

/**
* Created With Intellij
* User: lisongfeng
* Date: 16/6/3
* Time: 下午5:34
*/
import org.apache.spark.SparkConf
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._

/**
* @author Administrator
*/
object LineCount {

def main(args: Array[String]) {
val conf = new SparkConf()
.setAppName("LineCount")
.setMaster("local[3]")
val sc = new SparkContext(conf);

val lines = sc.textFile("/usr/local/README.md", 3)
lines.filter( _.contains("Home")).foreach(println)
val lines1 = sc.textFile("/usr/local/README1.md", 3)

val rdd2 = lines.union(lines1)
rdd2.foreach(println _ )

lines.map(_ * 2)

}

}

配置下Intellij右上角主类，就能跑起来了。

可以插入断点，可以把断点插入到Executor、Driver等中。

项目执行结果如下：
