> Since HADOOP-18649, in container-log4j.properties, 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.

> 2023-09-08 11:31:34,494 INFO [AsyncDispatcher event handler] org.apache.hadoop.yarn.util.RackResolver: Got an error when resolve hostNames. Falling back to /default-rack for all. {code}
> Note: log4j.appender.\{APPENDER}.MaxFileSize is not set before, then use default value 10M, so no problem before HADOOP-18649
