[jira] [Created] (KAFKA-8274) Old Committed messages got replayed after Kafka cluster Restart

Hrishikesh tiwary created KAFKA-8274:
----------------------------------------

             Summary: Old Committed messages got replayed after Kafka cluster Restart
                 Key: KAFKA-8274
                 URL: https://issues.apache.org/jira/browse/KAFKA-8274
             Project: Kafka
          Issue Type: Bug
          Components: consumer
    Affects Versions: 1.0.0
         Environment: PROD
            Reporter: Hrishikesh tiwary


I got a very serious issue in PROD Env . after restarting the Kafka cluster my old committed messages by same group if got replayed.

Its very shocking that if messages are already committed  by a group id then how comes same messages will be replayed by same group id.

I have a consumer which runs in web based application, at start up it starts the consumer by providing a group id. there is only one group id for the given web app.
