手動創建后仍然提示 topic[] not exist, apply first please

       昨天晚上同事碰到個問題，rocketMq 在test和dev環境創建的topic ，默認是自動創建的沒有問題，但是在pre環境卻不行。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]

    就是沒有找到對應的topic，按說應該是自動創建的，但是手動創建后仍然不行。

   這好奇怪。  最后是通過添加了 instanceName 解決了，但是這里面的邏輯自己仍然沒有理清楚。
