spark学习10（win下利用Intellij IDEA搭建spark开发环境）
第一步：启动IntelliJ IDEA，选择Create New Project，然后选择Scala，点击下一步，输入项目名称wujiadong.spark继续下一步
第二步：导入spark-assembly-1.5.1-hadoop2.6.0.jar包
File——Project Structure——Libraries——点+号——点java——选择下载好的spark-assembly-1.5.1-hadoop2.6.0.jar包——点ok
第三步：创建WordCount类编写代码
第四步：导出jar包
依次选择“File”–> “Project Structure” –> “Artifact”，选择“+”–> “Jar” –> “From Modules with dependencies”，选择main函数，并在弹出框中选择输出jar位置，并选择“OK”。
最后依次选择“Build”–> “Build Artifact”编译生成jar包。具体如下图所示。
第五步：spark-submit提交运行
