Subject [jira] [Created] (YARN-2000) Fix ordering of starting services inside the RM
Date Wed, 30 Apr 2014 04:03:24 GMT
Jian He created YARN-2000:

             Summary: 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
            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.
