> {quote}
> Current by design behavior is for winutils to ACL the folders only for the
> user passed in thru chmod/chown. This causes some un-natural side effects in
> cases where Hadoop services run in the context of a non-admin user. For
> example, Administrators on the box will no longer be able to:
> - delete files created in the context of Hadoop services (other users)
> - check the size of the folder where HDFS blocks are stored
> {quote}
> In my opinion, it is natural for some special accounts on Windows to be able
> to access all the folders, including Hadoop folders. This is similar to Linux
> in the way root users on Linux can always access any directories regardless
> the permissions set the those directories.
