在新机房部署Kafka 1.0.0时遇到创建topic失败，错误提示“TRACE”协议未被识别。解决方案是修改配置文件，将协议从”TRACE“改为”INFO“，重启Kafka后问题得到解决。

今天在新机房部署kafka的时候，趁机使用了最新的1.0.0版本的kafka。但是安装部署完成后，在创建topic的时候，居然出错了：

$ bin/kafka-topics.sh --create --zookeeper 192.168.1.1:2685/kafka --replication-factor 2 --partitions 3 --topic innertest

关键错误应该是”TRACE”协议不被识别：

Caused by: java.lang.IllegalArgumentException: No security protocol defined for listener TRACE

于是，试着在配置文件中，把

advertised.listeners=PLAINTEXT://192.168.1.1:9099, TRACE://192.168.1.1:9098

改成

advertised.listeners=PLAINTEXT://192.168.1.1:9099

然后重启kafka，再尝试创建topic，就好了。

总结：

在1.0.0版本的kafka中，不再支持”TRACE”协议，这个在之前的版本中应该只是测试用。
