>
> Deploy a cluster using blueprint when all nodes are in HEARTBEAT_LOST state
> (e.g. nodes already registered with Ambari server once but than all were
> stopped prior posting the blueprint/cluster creation template to the server).
> The blueprint and cluster creation succeeded and UI looked good with all the
> hosts in heartbeat-lost state.
> Then start the agents one by one. Expected behaviour is that as soon as all
> required nodes are up Ambari to start scheduling tasks on the connected
> nodes to install the cluster.
> However the hosts were stuck in {{host_status: UNKNOWN}} state and Ambari did
> not start scheduling any tasks to the connected hosts.
