amwyyyy opened a new issue #2545: URL: https://github.com/apache/rocketmq/issues/2545
Version: rocketmq-client:4.7.1 We use rocketmq-client to connect to aliyun RocketMQ(ONS), When upgrade from rocketmq-client:4.5.1 to rocketmq-client:4.7.1, the following error log appears: ``` 2021-01-04 15:20:19,019 WARN RocketmqClient - updateTopicRouteInfoFromNameServer Exception org.apache.rocketmq.client.exception.MQClientException: CODE: 17 DESC: No topic route info in name server for the topic: TBW102 See http://rocketmq.apache.org/docs/faq/ for further details. at org.apache.rocketmq.client.impl.MQClientAPIImpl.getTopicRouteInfoFromNameServer(MQClientAPIImpl.java:1383) at org.apache.rocketmq.client.impl.MQClientAPIImpl.getTopicRouteInfoFromNameServer(MQClientAPIImpl.java:1353) at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:622) at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:509) at org.apache.rocketmq.client.impl.factory.MQClientInstance.updateTopicRouteInfoFromNameServer(MQClientInstance.java:358) at org.apache.rocketmq.client.impl.factory.MQClientInstance$3.run(MQClientInstance.java:275) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) ```   Comparing the code of the two versions, it is found that modified here. What can I do to avoid printing warn logs? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
