添加cloudera仓库

</repository>
</repositories>
  <dependencies>

添加hadoop依赖
  <dependency>
      <groupId>org.apache.hadoop</groupId>
      <artifactId>hadoop-client</artifactId>
      <version>${hadoop.version}</version>
    </dependency>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>${junit.version}</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  
</project>

但是始终下载不了 hadoop的相关jar包  

最终我发现一个错误 ，就是  install的时候 下downloading hadoop  的地址竟然是aliyun  !!!

于是我在 maven --conf----setting.xml   配置aliyun 的地方进行修改

<mirror>
    <!--This sends everything else to /public -->
    <id>nexus-aliyun</id>
    <mirrorOf>*,!cloudera</mirrorOf>    这里 * ,!cloudera是既使用aliyun  又使用cloudera仓库的意思
    <name>Nexus aliyun</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>

然后重新install 发现 开始下载hadoop相关jar包了
