We are not actively developing and testing against this configuration.
I got this info of the userlist of Mesos. Can you confirm this?
AFAIK, the OpenShift do not include Kubenetes-Mesos distro when I try it month ago, but I do not know if it includes Kubenetes-Mesos distro for now. You can double check if there is a binary named as "km" which is in same directory as "kubelet", if the "km" is there, then you can migrate your Kubernetes running on Mesos by following https://github.com/kubernetes/kubernetes/blob/master/docs/getting-started-guides/mesos.md
; otherwise, you cannot.
