--------------------------------------
Hi [~jianhe], do you mind finishing YARN-1474? These JIRAs can be conflicted.
> Fix ordering of starting services inside the RM
> -----------------------------------------------
>
> Key: YARN-2000
> URL: https://issues.apache.org/jira/browse/YARN-2000
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: resourcemanager
> Reporter: Jian He
> Assignee: Jian He
>
> The order of starting services in RM would be:
> - Recovery of the app/attempts
> - Start the scheduler and add scheduler app/attempts
> - Start ResourceTrackerService and re-populate the containers in scheduler
> based on the containers info from NMs
> - ApplicationMasterService either don’t start or start but block until all
> the previous NMs registers.
> Other than these, there are other services like ClientRMService, Webapps
> which we need to think about the order too.
