[jira] [Created] (KAFKA-13932) Replication data loss in some cases

Bale created KAFKA-13932:
----------------------------

             Summary: Replication data loss in some cases
                 Key: KAFKA-13932
                 URL: https://issues.apache.org/jira/browse/KAFKA-13932
             Project: Kafka
          Issue Type: Bug
          Components: mirrormaker
    Affects Versions: 2.8.0
            Reporter: Bale


Kafka version: 2.8.0
Replication flow: A -> B
Topic: DL2 -> A.DL2
 
I use mm2 to replicate cluster A data to cluster B. In some cases, I found consumer group offset is bigger than partition offset in cluster B which will cause data loss of the mirror topic.
