Naganarasimha G R commented on YARN-4372:
-----------------------------------------

Thanks for raising this issue [~vinodkv], yes it would be better to correct the order, as in future if we start collecting ATSv2 system events then we will be having issues later. Issue i faced when i was testing with correcting the order was : the timeline service was having some issue starting the web service though the port was correctly set (was not an expert with jersey and guice, hence had stopped further analysis there) 

Also one more point(not related to this jira) to note in MiniYARNCluster, we no more support old  AHS interfce so basically {{yarn.timeline-service.generic-application-history.store-class}} should not be configured in {{ApplicationHistoryServerWrapper}} so that levelDBtimelinestore is created. which i feel is correct atleast for existing 2.7.x versions. And if you agree with it, can we fix it along with this jira as its a small thing ?,

> The way daemons are started inside MiniYARNCluster, RM is not setup correctly to send information to TimelineService.
