Subject [jira] Updated: (HADOOP-1298) adding user info to file
Date Wed, 02 May 2007 00:13:15 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.patch6

Added chgrp and more functionality to ls. We now have a programmatic way to discover if the
file is readable, writable or executable. 

there is a known bug with the groups as I don't want to send the server side groups over the
wire but the permissions object uses the data structure. The probable fix is to send a FSPermissions
object instead. 

Feedback would be greatly appreciated on this. I plan to very shortly push this patch.

> 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.
