Bikas Saha commented on HADOOP-8457:
------------------------------------
IMO, to me calling FileStatus.isOwnedBy() seems like a natural API to use. I
agree it would be nice to have something other than UGI to represent user/group
information but unfortunately there does not seem to be any such abstraction. I
would ideally like to see FileStatus.getOwner().equals(ownerObj) where ownerObj
is an object representing the owner that encapsulates users/groups etc.
Currently ownerObj is simply a string name and it has worked because of simple
1 owner, 1 group Unix model.
> Address file ownership issue for users in Administrators group on Windows.

> On Linux, the initial file owners are the creators. (I think this is true in
> general. If there are exceptions, please let me know.) On Windows, the file
> created by a user in the Administrators group has the initial owner
> ‘Administrators’, i.e. the the Administrators group is the initial owner of
> the file. As a result, this leads to an exception when we check file
> ownership in SecureIOUtils .checkStat() method. As a result, this method is
> disabled right now. We need to address this problem and enable the method on
> Windows.
