fsck command can display usage if user passes any other arguments with '-' ( other than -move,
-delete, -files , -openforwrite, -blocks , -locations, -racks).
--------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HDFS-1727
                 URL: https://issues.apache.org/jira/browse/HDFS-1727
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Uma Maheswara Rao G
            Priority: Minor


In fsck command if user passes the arguments like 
   ./hadoop fsck -test -files -blocks -racks 
   In this case it will take / and will display whole DFS information regarding to files,blocks,racks.

But here, we are hiding the user mistake. Instead of this, we can display the usage if user
passes any invalid argument like above.
