Subject [jira] [Updated] (AMBARI-21482) 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'' is not available in Blueprint.

     [ https://issues.apache.org/jira/browse/AMBARI-21482?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Swapan Shridhar updated AMBARI-21482:
-------------------------------------
    Description: 
*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.

> 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''
is not available in Blueprint.
