This takes the HLS distribution module offline causing Matterhorn to appear in an error state on the about page. This does not indicate a real problem but you can optionally choose to fix it by manually deleting the module from the Matterhorn database:.
delete from mh_service_registration where service_type = 'org.opencastproject.distribution.hls';
Note that if you do this you should also remove the HLS distribution steps from the avalon workflows in /usr/local/matterhorn/etc/workflows.
