Subject [jira] Updated: (HADOOP-1298) adding user info to file
Date Fri, 18 May 2007 00:12:16 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1298?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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

    Attachment: hadoop-user-munncha.patch16

Next patch with some of doug's suggestions implemented. I finally broke down and had FileStatus
and Permissions extend PosixConstants. So shared functionality is stored there. This does
preclude any other implementations of the posix standard from existing, but i think that the
code reuse is what you want. I will probably change PosixConstants to PosixStandard to clear
up confusion. Permissions can become DFSPermissions, but it's not a big deal. 

Likewise some javadocs have been cleaned up. That process will continue tomorrow.

> 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.
