-----------------------------

             Summary: Sort queue and apps in fair schduler using a separate thread
                 Key: YARN-8639
                 URL: https://issues.apache.org/jira/browse/YARN-8639
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: yarn
            Reporter: wan kun


If fair scheduler have many queue and each queue have many active applications .

For each assignContainer function, we need to sort all the queue, and all the applications in each queue. For a large system,this may be cost too much time. So we can sort the queue and applications using a separate thread asynchronous.
