--------------------------------------
Resolution: Fixed
> Blueprints: HSI config 'num_llap_nodes' and 'num_llap_nodes_for_llap_daemons'
> should be calculated and recommended via Stack Advisor during Blueprint
> install only if 'num_llap_nodes' config value is not provided in Blueprint.

> *Current:* HSI config *'num_llap_nodes_for_llap_daemons*' is calculated and
> recommended via Stack Advisor during Blueprint install and
> *''num_llap_nodes''* value is not used for
> *'num_llap_nodes_for_llap_daemons*' calculation, if available in Blueprint.
> *Issue* : This creates the problem of calculating value for
> *'num_llap_nodes_for_llap_daemons'*, in which calculation doesn't includes
> using the *'num_llap_nodes'* value.
> We need to use *'num_llap_nodes'* config value (if provided in BP) while
> calculating value for *'num_llap_nodes_for_llap_daemons'* during cluster
> creation call to Stack Advisor.
> *Fix* : During BP cluster install call to SA, recommendation for
> *'num_llap_nodes_for_llap_daemons'* should use value of *'num_llap_nodes'*
> config if specified in the cluster BP call.
