[GitHub] [rocketmq-externals] niceinfuture opened a new issue #847: [rocketmq-iot-bridge] optimize MQTT client equivalence judgment logic

niceinfuture opened a new issue #847:
URL: https://github.com/apache/rocketmq-externals/issues/847


   **BUG REPORT**
   
   1. Please describe the issue you observed:
   There is a problem with the MQTT client judgment, just use the "clientId" to judge the judgment may be wrong.
   - The client mainly contains clientId and ChannelHandlerContext information.
   - When two different clients with the same clientId connect and subscribe to the same topic message, one of the clients unsubscribes the topic, which will cause the other client to also be unsubscribed.
   - The equivalence of the client connection needs to be judged by combining clientId and ChannelHandlerContext.
   
   2. Please tell us about your environment:
   Linux
