Hi, yun:
In shell, you can use bin/hadoop dfs -ls to list directory.
If you want to access dfs in your code, you need write code as
following:
Configuration conf = new Configuration();
FileSystem fs = get (conf);
And then, you can access file system through fs. Refer java doc for more
details.
Regards.
