Subject [jira] Commented: (HADOOP-1298) adding user info to file

Raghu Angadi commented on HADOOP-1298:
--------------------------------------

Yes, even if we have enough memory, I don't think there is any special advantage of including
authentication server functionality in Namenode.

What we are actually interested is examples of embedding kerberos 'client' functionality as
a 'service provider'.  I mean Namenode should be able to do what ever it needs to do to be
one of the the service providers in a kerberos network.

> 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.
