[GitHub] [rocketmq] lizhanhui commented on issue #4771: In HA mode, if you do not truncate consumerOffsetMap, it may cause a bug

   I believe this is a design flaw. Leader/master nodes shall **ONLY** replicate their WAL logs to their peers/slaves.  All activities, including updates of consume-offsets, should be reflected in the WAL log. Peer nodes and slaves restore state machines by replaying WAL.
   
   The current implementation has more than one replication path, this is the root cause of the discrepancy.
