------------------------------------------
Regarding point 7 above. Suppose we support creation time/modification time of
a file. These will not be part of the Permissions object becuase they have
nothing in common with uid/gid. Instead they might be two new fields in the
INode. This means that logCreateFile would need to take two additional
parameters. The second parameter to logEdit() is currently an array of size 2.
Instead it could be an array of size 3.
Regarding having a Permission object embedded in the INode: it might be
preferable to make the INode contain the two new Integer fields (owner and
ownerGroup) directly. It should save some memory.

> 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.
