Björn Eriksson created KAFKA-5546:
-------------------------------------

             Summary: Lost data when the leader is disconnected.
                 Key: KAFKA-5546
                 URL: https://issues.apache.org/jira/browse/KAFKA-5546
             Project: Kafka
          Issue Type: Bug
          Components: producer 
    Affects Versions: 0.10.2.1
            Reporter: Björn Eriksson
         Attachments: kafka-failure-log.txt

We've noticed that if the leaders networking is deconfigured (with {{ifconfig 
eth0 down}}) the producer won't notice this and doesn't immediately connect to 
the newly elected leader.

{{docker-compose.yml}} and test runner are at 
https://github.com/owbear/kafka-network-failure-tests with sample test output 
at 
https://github.com/owbear/kafka-network-failure-tests/blob/master/README.md#sample-results

I was expecting a transparent failover to the new leader.

The attached log shows that while the producer produced values between 
{{12:37:33}} and {{12:37:54}}, theres a gap between {{12:37:41}} and 
{{12:37:50}} where no values was stored in the log after the network was taken 
down at {{12:37:42}}.
