Cloudera Hadoop - 安装错误

Question

我是Linux和Hadoop的新手。 我想学习Pig，MapReduce和Hive的基础知识，我正在尝试在Ubuntu上安装Cloudera的Hadoop解决方案。 这是我正在关注的教程。 我坚持第1步。我没有使用代理，所以我跳过了代理配置步骤。 得到步骤1.6，然后我收到以下错误消息。 任何想法我应该尝试什么？

Refreshing repository metadata failed. See /var/log/cloudera-manager-installer/2.refresh-repo.log for details. Click OK to revert this installation.

这就是该日志文件中的内容：

Answer 1

看起来您已破坏与Cloudera无关的存储库引用，但导致安装失败。
