"Thank you, I was thinking that it's generally OK to deploy a mesos scheduler on a mesos slave node, regardless performance issue, say it will communicate with mesos master frequently."
I would avoid launching the scheduler on a mesos slave since the scheduler would run outside of Mesos jurisdiction (via cgroup), and may contend with mesos tasks for resource. We have MesosNimbus running outside of the mesos cluster, master or slave.
