> Quoting from HADOOP-3222 ("fsck should require superuser privilege"), 
> bq. I agree that it makes sense to make fsck do permission checking for the nodes that
it traverses. If a user does a fsck on files/directories that he/she has access to (using
permissions) then that invocation of fsck should be allowed. Since "/" is usually owned by
super-user, only super-user should be allowed to run fsck on "/".
