> *Current:* HSI config *'num_llap_nodes'* and
> *'num_llap_nodes_for_llap_daemons*' are calculated and recommended via Stack
> Advisor during Blueprint install whether or not *''num_llap_nodes''* is
> available in Blueprint.
> *Issue* : This creates the problem of calculating value for
> *'num_llap_nodes'* and *'num_llap_nodes_for_llap_daemons'* and overriding
> value for *'num_llap_nodes_for_llap_daemons'* which gets send as
> recommendation.
> We don't want to override and recommend value for
> *'num_llap_nodes_for_llap_daemons'* if *'num_llap_nodes'* is provided in the
> BP.
> *Fix* : Recommendation for *'num_llap_nodes_for_llap_daemons'* will only be
> made if *'num_llap_nodes'* is not specified in the cluster BP call.
