Doug Cutting commented on HADOOP-1298:
--------------------------------------

This is looking pretty good.  A few quick, mostly minor, comments:

0. You forgot to include Users.java.

1. FileStatus constructor javadoc example should use "0777" instead of "777".

2. FileStatus getters need javadoc comments.

3. Javadoc comments should start with a correctly punctuated sentence.

4. Commented-out code in FileSystem.java should be removed.

5. Whitespace-only changes should be removed.

6. Permissions should be package-private, not public.

I've still not closely examined the DFS-internal changes.  Konstantin, Dhruba, 
can you please look this over again when you have a chance?  Thanks.

> 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.
