Raghu Angadi commented on HADOOP-1298:
--------------------------------------
FSNamesystem.create() (startFile() actually) does an
implicit mkdirs(), which does not check for permissions. We
should check that too. Currently client does an unnecessary
mkdirs() which helps with permissions, but I filed a jira to
remove it (HADOOP-1910).

> 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.
