Kurtis Heimerl commented on HADOOP-1298:
----------------------------------------
I've sent a new version up, as I'm sure everyone can see.
This implements groups and seperates the client side from the server side.
There are a few unresolved issues. the first of which is the mechanism for
putting groups into the server. It uses config and is ugly.
Currently,
fs.groups -> list of groups
for each in this list, a property fs.group.GROUP_NAME should exist.
It has the associated users.
You should be able to call the init method at run time to add new users to the
system. It's that or check this file every time a user connects.
Lastly, I need to implement Unix permissions. I don't see any obvious way to do
this in java, the closest is 3 integers, one for user, one for groups and one
for everyone. Does that sound reasonable?

> 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.
