Tsz Wo (Nicholas), SZE commented on HADOOP-1298:
------------------------------------------------
checkPermission header should be checkPermission(FilePermission), like the one
in java.security.AccessController. Don't need to pass principal since the
current javax.security.auth.Subject should be known to the system.
I will have a updated class layout very soon.

> I'm working on adding a permissions model to hadoop's DFS. The first step is
> this change, which associates user info with files. Following this I'll
> assoicate permissions info, then block methods based on that user info, then
> authorization of the user info.
> So, right now i've implemented adding user info to files. I'm looking for
> feedback before I clean this up and make it offical.
> I wasn't sure what release, i'm working off trunk.
