Description
分析是对象池中MQClientInstance定时线程updateTopicRouteInfoFromNameServer，会默认扫描TBW102，但是对于broker配置autoCreateTopicEnable=false，并没有生成TBW102的topic，不知道这种的日志中不停出现告警信息，有什么处理方式没有？
具体告警日志如下：
2021-04-28 10:34:33 WARN MQClientFactoryScheduledThread - updateTopicRouteInfoFromNameServer Exception
org.apache.rocketmq.client.exception.MQClientException: CODE: 17 DESC: No topic route info in name server for the topic: TBW102
