rocketmq消费者组报错:CODE: 17 DESC: No topic route info in name server for the topic: %RETRY%consumer_01

自己部署了rocketmq后，按照网上教程手动创建消费者组，指明nameserver后进行消费，报错内容如下

org.apache.rocketmq.client.exception.MQClientException: CODE: 17 DESC: No topic route info in name server for the topic: %RETRY%consumer_01 See http://rocketmq.apache.org/docs/faq/ for further details., org.apache.rocketmq.client.impl.MQClientAPIImpl.getTopicRouteInfoFromNameServer(MQClientAPIImpl.java:1807)

找了两天没找到问题，今天终于找到了，创建消费者组时没有指定broker或者cluster的集群，导致消息发送到mq后找消费者组的时候找不到它对应的路由信息。

解决办法:创建时添加 -b 或者-c参数

如:

./mqadmin updateSubGroup -n 127.0.0.1:9876 -g TestConsume -b 127.0.0.1:10911

或者

./mqadmin updateSubGroup -n 127.0.0.1:9876 -g my_consumer_group -c rocketmq-cluster

问题解决，开心，下周要在公司做mq集群了
