The maintenance schedules require that schedulers implement support for them. Nothing happens if the scheduler does not have support for the maintenance schedules. The DRAIN_AGENT in Mesos 1.9 does not require scheduler support (Mesos will kill the tasks). As a result, it is up to the operator issuing the DRAIN_AGENT request to not violate higher level SLAs. See this thread for context: https://lists.apache.org/thread.html/c0414897debdea2faffbffc81fa36c435e109e7ff80c72c544b4d135@%3Cdev.mesos.apache.org%3E As to what support marathon has for maintenance schedules, the ticket you pointed to what closed in favor of https://jira.mesosphere.com/browse/DCOS-54915. This new ticket is only about DRAIN_AGENT as far as I can tell. If so, then there is a gap in the marathon ticketing for supporting SLA aware maintenance.
