- When "hive.warehouse.subdir.inherit.perms" flag is enabled in Hive, Hive will try to do all above inheritances. In the future, we can add more flags for more finer-grained control.
- Failure by Hive to inherit will not cause operation to fail. Rule of thumb of when security-prop inheritance will happen is the following:
- To run chmod, a user must be the owner of the file, or else a super-user.
- To run chgrp, a user must be the owner of files, or else a super-user.
- Hence, user that hive runs as (either 'hive' or the logged-in user in case of impersonation), must be super-user or owner of the file whose security properties are going to be changed.
