Description

Given that "num_llap_nodes_for_llap_daemons" only exists in 2.6 HDP stack, there can be a scenario where "num_llap_nodes_for_llap_daemons" doesnt exist in hive-interactive-site. This can happen if we upgrade from Ambari 2.4 (with HDP 2.5) to Ambari 2.5.

Fix: Set this config in SA only if it present in hive-interactive-env.
