看不到hdfs，Hadoop shell命令hadoop fs -ls给出错误无法访问

我面临一个奇怪的问题，我无法看到我的hdfs文件。 每当我做一个hadoop fs -ls我得到下面的错误：

hadoop fs -ls Warning: $HADOOP_HOME is deprecated. ls: Cannot access .: No such file or directory.

我可以使用像copyfromlocal等命令，但仍然不能看到他们在hdfs也不能运行猪脚本由于这个问题。 如果我做一个hadoop fs -ls / *我得到下面的错误：

hadoop fs -ls /* Warning: $HADOOP_HOME is deprecated. Found 1 items drwxr-xr-x - hduser hadoop 0 2014-02-14 16:49 /app/hadoop ls: Cannot access /bin: No such file or directory. ls: Cannot access /boot: No such file or directory. ls: Cannot access /Data: No such file or directory. ls: Cannot access /dev: No such file or directory. ls: Cannot access /etc: No such file or directory.

任何人都可以让我知道这里可能是什么问题？ 我有一个7节点hadoop群集工作正常。 我仅在2天左右才遇到这个问题。 已经尝试重启群集，重启节点等，但仍面临同样的问题。

谢谢，

你的hadoop没有问题

hadoop fs -ls

没有显示任何输出，因为当前用户的主目录中没有目录或文件（从中执行命令）

请运行第二个命令

hadoop fs -ls /

代替

hadoop fs -ls /*

这将工作正常，并会给你正确的输出。
