--------------------------------------

Thanks Christophe.

I just compiled and I noticed the following warning: 
{noformat}
   [javac] 
/home/rangadi/hadoop-perms/src/java/org/apache/hadoop/dfs/DFSPolicy.java:50: 
warning: sun.security.provider.PolicyFile is Sun proprietary API and may be 
removed in 
a future release
    [javac]   Policy delegate = new sun.security.provider.PolicyFile();
    [javac]                                              ^
    [javac] Note: Some input files use or override a deprecated API.
    [javac] Note: Recompile with -Xlint:deprecation for details.
    [javac] 1 warning
     [copy] Copying 2 files to /home/rangadi/hadoop-perms/build/classes

Is this considered? Quick search in the jira does not reveal anything.

> 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.
