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

             Summary: Container logs are missing when yarn.app.container.log.filesize is set to default value 0.
                 Key: YARN-11565
                 URL: https://issues.apache.org/jira/browse/YARN-11565
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 3.3.6
            Reporter: zhengchenyu
            Assignee: zhengchenyu


Since HADOOP-18649, log4j.appender.\{APPENDER}.MaxFileSize is set to ${yarn.app.container.log.filesize}, but yarn.app.container.log.filesize is 0 in default. So log is missing. This log is always rolling and only show the latest log.

This is the running log like below:
