Subject [jira] Commented: (HADOOP-1298) adding user info to file
Date Fri, 18 May 2007 21:51:16 GMT

Doug Cutting commented on HADOOP-1298:
--------------------------------------

I forgot about EnumSet.  Yes, that could work well.  It'd be more work to serialize it efficiently
(we'd probably still want to pack it into a short), but it would be much more type-safe.

> 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.
