Sumit Mohanty, i've created separate jira https://hortonworks.jira.com/browse/BUG-74552 for RU/EU changes and assigned it to Dmytro Grinenko. Pay attention that iset "add on upgrade false", i think we don't need it. It's first ambari version where we have HDP-2.6. For fresh install of HDP 2.6 it will appear because it's already added to config and stack advisor. And during RU/EU it will appear too after Dmytro Grinenko's changes.
