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. > -------------------------------------------------------------------------- > > Key: HADOOP-8457 > URL: https://issues.apache.org/jira/browse/HADOOP-8457 > Project: Hadoop Common > Issue Type: Bug > Components: native > Affects Versions: 1.1.0, 0.24.0 > Reporter: Chuan Liu > Assignee: Ivan Mitic > Priority: Minor > Attachments: HADOOP-8457-branch-1-win_Admins(2).patch, > HADOOP-8457-branch-1-win_Admins.patch > > > On Linux, the initial file owners are the creators.
