不多说，直接查询相关的内容
https://mvnrepository.com/search?q=spark

我们可以看到很多常见的东西，spark-core,spark-sql,spark-streaming等等
点开这些链接进入到版本列表界面，选择自己需要的配置
spark-core

spark-streaming

这里就不一一说明了，下面我直接列出一个已经测试成功的pom.xml

这里不建议在dependency中写死version，而是采用一下方式

<hadoop.version>2.6.5</hadoop.version>

在我的配置中有4个hadoop.version，如果写死了，那么后边要进行统一的hadoop升级，你该如何操作？一个一个找，然后修改4个位置？如果这里有上百个依赖，你该如何操作。

这个pom.xml修改完毕，保存后，我的eclipse上爆出了170个problems，但是不要慌，进行如下操作
