Subject [jira] Commented: (HADOOP-1298) adding user info to file
Date Mon, 10 Sep 2007 19:09:30 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12526226

Raghu Angadi commented on HADOOP-1298:

bq. Only a rough one at this point. The idea is that the client submits an authorization ticket
along with each job, then the tasktracker uses that ticket when accessing the filesystem.
Folks who are serious will use something like Kerberos, which is well suited. By default,
the ticket will just be a username, with no authentication.

This outline matches what I was thinking. I will file another jira. I could look into the
changes required.

> 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.
