hdfs - why does my hadoop command does not work? -

-

i have hadoop cluster set 1 master , 2 slaves. when type 

hadoop fs -ls  ls: cannot access .: no such file or directory.

but when type following:

hadoop fs -ls / found 1 items drwxr-xr-x   - mike supergroup          0 2014-06-24 00:24 /usr

i same output both on master , slaves. why hadoop fs -ls not work?

thanks!

  hadoop fs -ls

this tries list current user's home directory on hdfs. since think /user/{username} directory doesn't exist in case hence error, 

  hadoop fs -ls /

you telling list root directory exist.
