Spark用IntelliJ + maven打jar包上传到Spark集群上运行
因为需要用Hadoop的HDFS所以要启动Hadoop
1.启动Hadoop
2.启动Spark集群
3.打开IntelliJ
创建maven项目
然后配置maven项目的pom.xml文件
内容如下
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<encoding>UTF-8</encoding>

删掉多余jar除了最后一个文件（因为这样jar包内存会小很多，一般集群上都有删除掉的那些jar包的），点击apply然后点击ok
拷贝jar包到你方便的位置
5.上传jar包并运行
6。查看结果
