Subject [jira] Commented: (HADOOP-1298) adding user info to file
Date Thu, 26 Apr 2007 07:39:15 GMT

Owen O'Malley commented on HADOOP-1298:
---------------------------------------

This looks like a reasonable start. I think that in the ClientProtocol that the create method
should have User rather than complete. My reasoning is that you want to stop the user quickly,
before  they start writing to the file. Actually, all of the namespace operations should take
User:
   create
   delete
   exists
   getHints
   getListing
   isDir
   mkDirs
   open
   rename
   setReplication

On a side note, you've got some spurious whitespace changes that should be reverted.

> 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.
