> Key: YARN-11274
> URL: https://issues.apache.org/jira/browse/YARN-11274
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager
> Affects Versions: 3.4.0
> Reporter: fanshilun
> Assignee: fanshilun
> Priority: Minor
> Labels: pull-request-available
>
> 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
