      Description

       I configured log4j to send application logs to kafka.

      There is no more producer, one only. So I couldn't figure out what's happened.

      ---------------log4j.properties--------------------------------

      log4j.rootLogger=INFO, kafka

      #appender kafka
      log4j.appender.kafka=org.apache.kafka.log4jappender.KafkaLog4jAppender
      log4j.appender.kafka.topic=UAT_APP
      log4j.appender.A1.Threshold=INFO
      log4j.appender.kafka.syncSend=false

      #multiple brokers are separated by comma ",".
      log4j.appender.kafka.brokerList=localhost:9091,localhost:9092,localhost:9093,
      log4j.appender.kafka.layout=org.apache.log4j.PatternLayout
      log4j.appender.kafka.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %p %t %c (%F:%L) - %m%n

      ----------------end log4j.properties--------------------------------------

      It's the error log below.
