> If topology tasks are generated in parallel during Blueprint deployment
> (topology.task.creation.parallel=true) sometimes concurrent modification of
> HostComponentDesiredState entity might be modified concurrently which results
> in desiredState remaining in INIT state. As a result HostRoleCommand for
> START topology task is not generated and remains in PENDING state.
