> 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.
> The problem appears when a component is set as restartRequiredAfterRackChange
> in stack definition. In this case when host components are created by
> PersistHostResourcesTask restartRequired is set to true on the same component
> on other hosts, meanwhile InstallHostTask is running which sets the
> desiredState for the same component. As both restartRequired and desiredState
> fields are stored in HostComponentDesiredState entity it could happen then
> when updating restartRequired field desiredState is reverted back to INIT
> state.
