Infff5923686all occurences of users.extraUsers and users.extraGroups have been changed tree-wide to users.users and users.group. In the meantime the hadoop modules were introduced via #41381 (060a98e9f4). Unfortunately those modules still use users.extraUsers, which has been renamed a long time ago (14321ae243, about three years from now), so let's actually rename it accordingly as well.
