手动创建后仍然提示 topic[] not exist, apply first please

       昨天晚上同事碰到个问题，rocketMq 在test和dev环境创建的topic ，默认是自动创建的没有问题，但是在pre环境却不行。日志里面提示是 

     

com.alibaba.rocketmq.client.exception.MQClientException: Send [5] times, still failed, cost [24]ms, Topic: astrict_driver_refresh_crowd, BrokersSent: [broker-a, broker-b, broker-a, broker-b, broker-a]

    就是没有找到对应的topic，按说应该是自动创建的，但是手动创建后仍然不行。

   这好奇怪。  最后是通过添加了 instanceName 解决了，但是这里面的逻辑自己仍然没有理清楚。
