Hi all, How to set log4j.appender.kafkaAppender through environment variable? I use LOG4J_APPENDER_KAFKAAPPENDER=org.apache.log4j.RollingFileAppender when run kafka container, but in /opt/kafka/config/log4j.properties is log4j.appender.kafkaappender=org.apache.log4j.RollingFileAppender , not kafkaAppender, all uppercase changed to lowercase.
