Doug Cutting commented on HADOOP-1298:
--------------------------------------
I forgot about EnumSet. Yes, that could work well. It'd be more work to
serialize it efficiently (we'd probably still want to pack it into a short),
but it would be much more type-safe. +0

> 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.
