Christophe Taton commented on HADOOP-1298:
------------------------------------------
I'll add a new kind of ticket which holds a user name
instead of a user id. Should I enhance the DFSClient to set
the user name as specified in the Configuration, or the
current user id, if nothing is specified?
If the user name is not in the user.database.file, any
operation will fail (throws an IOException as a result of
not being able to resolve the name into an id).
This makes the system quite static. Can we assume, for now
at least, that users will not be created/removed everyday?

> 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.
