> 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
> command usage if user passes any invalid argument like above.
> If user passes illegal optional arguments like
> ./hadoop fsck /test -listcorruptfileblocks instead of
> ./hadoop fsck /test -list-corruptfileblocks also we can display the proper
> command usage
