[jira] [Created] (KAFKA-13856) MirrorCheckpointTask meets ConcurrentModificationException

Justinwins created KAFKA-13856:
----------------------------------

             Summary: MirrorCheckpointTask meets ConcurrentModificationException
                 Key: KAFKA-13856
                 URL: https://issues.apache.org/jira/browse/KAFKA-13856
             Project: Kafka
          Issue Type: Bug
          Components: mirrormaker
    Affects Versions: 3.0.1
            Reporter: Justinwins


In MirrorCheckpointTask.java, the field 

private Map<String, List<Checkpoint>> checkpointsPerConsumerGroup = new HashMap<>

may be modified ( used with put API) , and traversed  by two different threads at the same time.

Clearly,this would incur ConcurrentModificationException.

 

This bug still exists in Trunk branch.
