> When a host is removed from the cluster and later from ambari there's a chance the agent
registers back to the ambari server before the agent is stopped.
> Stopping the machine running the agent without the host being deleted again leads to
an inconsistent state in the ambari-server due to cached state.
> Resolution:
> The cached resources get cleared on host delete event.
