Tom White commented on HADOOP-1298:
-----------------------------------
Point 2. could also been done with enums in a more typesafe manner with
something like
public enum Permission {
OWNER_READ,
OWNER_WRITE,
GROUP_READ,
GROUP_WRITE,
OTHER_READ,
OTHER_WRITE
}
FileStatus status = new FileStatus(Path, user, group,
EnumSet.allOf(Permission.class);
FileStatus status = new FileStatus(Path, user, group, EnumSet.of(OWNER_READ,
OWNER_WRITE, GROUP_READ));
We could also define constants for OWNER_RW etc and PERMIT_ALL as EnumSets if
desired.

> 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.
