就像我运行命令时的状态一样 sudo service hadoop-hdfs-namenode start 命令失败，出现以下消息。

这个错误本身是不言自明的，目录/var/lib/hadoop hdfs/cache/hdfs/dfs/name丢失，这是正确的。缓存目录为空，因此我创建了/cache/hdfs/dfs/name。我还更改了所有者和组，使其与上面目录的所有者和组匹配。hdfs:hadoop.
我再次运行format命令 sudo -u hdfs hdfs namenode –format 其结束方式与创建此目录之前相同。

我的系统运行在virtualbox中，带有centos6.6客户机oraclejdk1.7，并尝试运行clouderacdh4。如果您对下一步如何解决这个问题有任何意见，我们将不胜感激。

格式化namenode时遇到了相同的问题。重新键入突击队（不是复制粘贴）：

hdfs namenode -format

成功了。谢谢https://stackoverflow.com/users/4533812/james

如果从幻灯片或其他地方复制并粘贴format命令，您是否可以实际键入它并查看它是否有效？
我不知道你能不能看出
–格式和–格式。
我觉得 Jmeter 盘不一样。
