搭建Spark源码阅读环境

1.安装JDK1.7、Maven3.2.5、Scala2.10.4

2.下载解压Spark1.4.0

下载地址：
http://mirrors.cnnic.cn/apache/spark/spark-1.4.0/spark-1.4.0.tgz

3.下载安装 IntelliJ IDEA 14.1.4，给IDEA安装 Scala 插件，然后导入Spark项目





4.在IDEA中编译Spark

若编译时遇到如下图所示的错误：



在Maven视窗点击“Generate Sources and Update Folders For All Projects”，可解决此问题



在“Generate Sources and Update Folders For All Projects”过程中可能会遇到“Unable to import maven project: See logs for details”错误；可点击Help-->Show Log in Exploere，查看错误日志信息如下：

这种情况应该是GFW的原因，换一个时间段或者使用代理就可以了

5.在IDE中运行master：直接运行类org.apache.spark.deploy.master.Master，若报如下图所示错误



修改项目根路径下的pom.xml，将guava的版本为范围由provided修改为compile

<dependency>

<groupId>com.google.guava</groupId>

<artifactId>guava</artifactId>

<version>14.0.1</version>

<scope>compile</scope>

</dependency>

运行成功时，控制台输出如下：



6.在IDE中运行Worker：运行类org.apache.spark.deploy.worker.Worker，并指定参数 --webui-port 8081 spark://192.168.63.1:7077
