Hi Chanaka, Yes, I have encountered with this error while I was testing MSMP tasks in cluster mode. It was an intermittent issue.
@Kathees: Could you please restart the manager node again and make sure that you have started one or more workers in the meantime as Chanaka mentioned. AFAIK, manager node collects them as pending tasks and schedules later once workers joined the cluster.
