Sanjay Radia commented on HADOOP-8457:
--------------------------------------
The two approaches explored in this jira are
# When a local file is created, change the owner to the creator of the file
# Leave the owner of local file to policies of local file (ie Admin in the case
of Windows if the owner is an Admin). Add a method in FileStatus to check if
the owner is current user (so that it can match the behavior of the local file
system for local files) - current patch
Approach (2) seems reasonable except given the Hadoop APIs, apps are justified
to do fileStatus.getOwner().equals(currentUser).
Such code is probably all over the place and can't be avoided. Good news is
that LocalFs is used only for emulating Hadoop or for copying files back and
forth. Hard call on which is the right approach.
> 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.
