Raghu Angadi commented on HADOOP-2381:
--------------------------------------
will remove 's' from {{getPermissions()}} etc.
> Since we cannot make FsPermission immutable, is it better to return a new
> object every time? Otherwise, it is a security hole.
I was hoping 'final' will some how prevent it at runtime. I will make it throw
RuntimeException if someone invokes readfields one this default object. Would
that be ok?
> In RawLocalFileSystem.loadPermissions(), should it throws IOException (or
> return null) if there is any exception? Otherwise, we cannot tell whether the
> permission returned is real or just the default because the command failed.
Should getOwner() etc throw the IOException or return null?
> Support permission information in FileStatus
