URL: http://<db.host>:<hm.port>/admin/alter/host
Alter properties on an existing host in the cluster. Currently, the only property that can be altered is a hosts ability to accept failover processes. NOTE: This endpoint is serviced by the host manager, not the database cluster itself, so the port specified needs to be the host manager port instead. The default host manager port can be found under Default Ports. For more information on the host manager, see Host Manager.
