Yes, that would make sense, if we had sessions. But the current RPC framework
does not have any notion of session. So we either need to add it to RPC, or
make it a part of this protocol. We're likely to want user validation for
other protocols, so it does make sense to consider somehow adding it to the
framework. But, for now, explicitly passing a context as a parameter is
probably right. Longer-term, to implement sessions we might use a Proxy that
wraps a raw RPC proxy, keeping a context with the client that's passed to the
server on each call. Does that sound reasonable? Or should we add sessions
before users?

> 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.
