> MRAppMaster waits for 5 secs during app-finish, this was needed before we had
> client-side redirection. This affects the app execution in that, AppMaster
> will killed by the NM once NM gets
> confirmation from RM.
> AppMaster should go away immediately. Also, the done call to RM from AM
> should be the last thing AM ever does.
> Otherwise, today, JobHistory writing gets interrupted if AM gets killed by
> the NM.
