如何下载cdh版本的软件包

由于cdh版本的所有的软件涉及版权的问题，所以并没有将所有的jar包托管到maven仓库当中去，而是托管在了CDH自己的服务器上面，所以我们默认去maven的仓库下载不到，需要自己手动的添加repository去CDH仓库进行下载，以下两个地址是官方文档说明，请仔细查阅

例如：

创建Maven工程，引入pom依赖

<repositories>
    <repository>
        <id>cloudera</id>
        <url>https://repository.cloudera.com/artifactory/cloudera-repos/</url>
    </repository>
</repositories>
