本地Java大数据环境基础配置(Maven)[通俗易懂]

大家好，欢迎来到IT知识分享网。

创建项目

准备pom.xml文件配置（附在文档最后）

在下载jar过程中极其缓慢，简直不能忍受，查阅了下资料，得到下面的办法：

1、 maven仓库中没有支持cdh的相关依赖。cloudera自己建立了一个相关的仓库。要想利用maven添加相关依赖，则必须单独添加cloudera仓库

2、 在国内使用maven中央仓库一般会有网络问题，大部分人会使用aliyun仓库或者其他开源的仓库。所以需要修改setting.xml (以下配置中 *,!cloudera 表示除了aliyun仓库还使用cloudera仓库)

配置：

<mirror>
         <id>nexus-aliyun</id>
         <mirrorOf>*,!cloudera</mirrorOf>
         <name>Nexus aliyun</name>                    
         <url>
           http://maven.aliyun.com/nexus/content/groups/public
         </url>
</mirror>
