Hi Greg, The API call you mentioned to stop all components on a host still works in 1.7.0 (I just verified on my recent 1.7.0 cluster). Operation_level is not mandatory and the WARN can be ignored. Operation_level drives the behavior of operations when services/hosts/host_components are in maintenance mode. Unfortunately I don't see any documentation on this. I presume you are getting 200 because all components on the specified host are already stopped.
