Subject [jira] Updated: (HADOOP-1298) adding user info to file
Date Wed, 02 May 2007 23:29:15 GMT

Kurtis Heimerl updated HADOOP-1298:
-----------------------------------

    Attachment: hadoop-user-munncha.patch7

This patch addresses many of those issues:
Formatting and javadocs are future issues, once the architecture debate is settled. 

3-7 are implemented. 

I've also implemented a groups method. This will allow a programmatic access to file permissions,
if needed. 

I believe that either the scheme or the authority includes the user name, allowing it to be
multiplexed on that. I'll look over that again soon. 

Are there any other concerns over this design? A review of the DFS side of things would be
appreciated.

> 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.
