When permission is disabled, why setOwner() && setPermission() still check the permission?

[Brahma Reddy Battula]

Hi All

why  the "dfs.permissions.enabled" flag was not considered for this setOwner() 
and setPermission() check..?

and why extra super user required for setOwner()? is the check required even in 
case of permissions disabled?

Any idea on this..?



Thanks
