----------------------------------

             Summary: Write duplicate messages during broker failure
                 Key: KAFKA-908
                 URL: https://issues.apache.org/jira/browse/KAFKA-908
             Project: Kafka
          Issue Type: Bug
          Components: replication

            Reporter: Tudor Scurtu
            Assignee: Neha Narkhede
            Priority: Minor
Reproduction steps:
1. Start a multi-broker quorum (e.g. 3 brokers)
2. Create a multi-replica topic (e.g. 3 replicas)
3. Start an async performance producer with a fixed number of messages to produce
4. Force kill a partition leader broker using SIGKILL (no clean shutdown) - make sure you kill it during actual writes
5. Wait for the producer to stop
6. Read from the topic from the beginning - there will a small amount of duplicate messages
