Subject [jira] [Created] (YARN-5773) Skip LeafQueue#activateApplication for running application on recovery
Date Mon, 24 Oct 2016 13:07:59 GMT
Bibin A Chundatt created YARN-5773:
--------------------------------------

             Summary: Skip LeafQueue#activateApplication for running application on recovery
                 Key: YARN-5773
                 URL: https://issues.apache.org/jira/browse/YARN-5773
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bibin A Chundatt
            Assignee: Bibin A Chundatt
            Priority: Critical


# Submit application 10K application to default queue.
# All applications are in accepted state
# Now restart resourcemanager

For each application recovery {{LeafQueue#activateApplications()}} is invoked.Resulting in
AM limit check to be done even before Node managers are getting registered.

Total iteration for N application is about {{N(N+1)/2}} for {{10K}} application   {{50000000}}
iterations causing time take for Rm to be active more than 10 min.

Since NM resources are not yet added to during recovery we should skip {{activateApplicaiton()}}
