Subject [jira] Commented: (HADOOP-1298) adding user info to file
Date Thu, 26 Jul 2007 00:02:31 GMT

Christophe Taton commented on HADOOP-1298:
------------------------------------------

Ok I agree with you on the point and open a new issue for this now.

Sure I still want to work on adding user info to file.
The way you want to implement permissions, using java.security.Permission, and the way I did
it seems completely different, to my mind. I am deeply thinking about this now. Do you have
more details on the way you would like to implement this?

What is done in the previous patch is only an imitation of what we find in traditional file
systems.

> 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.
