> # 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()}}
