[GitHub] [rocketmq] ticsmtc6 opened a new issue #1459: orderly message, stop master broker, slave broker did not distribute message

ticsmtc6 opened a new issue #1459: orderly message,stop master broker,slave broker did not distribute message
URL: https://github.com/apache/rocketmq/issues/1459
 
 
   What did i do (The steps to reproduce)?
   1.send some messages to broker
   2.stop one master broker
   3.start orderly consumer
   
   What did i see?
   the stoped master broker's slave node did not distribute orderly message to consumer
   
   Please tell us about your environment:
   Java: 1.8
   RocketMQ: 4.2.0
   
   purpose:
   I want upgrade rocketmq from 4.2.0 to 4.5.1
   My thought is add 1m&1s 4.5.1 broker,recreate all topic,stop V4.2.0's master broker,consumer pull message from V4.2.0 slave broker,stop slave broker when this broker's all message are consumed
   Is there any way to avoid this problem?  Or other better way to accomplish upgrade?
