             Project: Hadoop YARN
          Issue Type: Improvement

    Affects Versions: 3.4.0
            Reporter: fanshilun
            Assignee: fanshilun


1.When RM performs master-slave switching, NM will re-register, report the list 
of running apps, and print the number of running apps
2.registerWithRM#containerReports is enough to print the number of prints, 
because the above calling process has already printed the container list, so 
there is no need to repeat printing
3.Use placeholders to display logs to avoid string concatenation
