Subject [jira] Commented: (HADOOP-1298) adding user info to file
Date Fri, 04 May 2007 00:01:15 GMT

Kurtis Heimerl commented on HADOOP-1298:
----------------------------------------

I've thought of a possible solution. Assuming no one comments by tomorrow, i'll implement
it then and move onto the documentation. 

My problem was that the client was sending 777 and getting 0xffff in return. 

So, this object can take an int in the chmod format. That makes a lot more sense. So 777 is
stored as 111111111 in the inode. However, in the FileStatus it will be 777. Thus the seperation
of the generic and non-generic FS. 

This seems a lot more sensible to me.

> 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.
