In my opinion, I think CLA should use FileAppender, and CRLA should use
RollingFileAppender.
FileAppender will disable the cap. Then CRLA will limited by maxFileSize and
maxBackups. Users can choose CLA or CRLA they want
> Container logs are missing when yarn.app.container.log.filesize is set to

> 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.
> This is the running log like below:

> Log Length: 0
> Log Type: syslog.1

> 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
