Björn Eriksson updated KAFKA-5546:
----------------------------------
Attachment: (was: kafka-failure-log.txt)
> Temporary loss of availability 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, 0.11.0.0
> Environment: docker, failing-network
> Reporter: Björn Eriksson
>
> 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.
> We were expecting a transparent failover to the new leader but testing shows
> that there's a 8-15 seconds long gap where no values are stored in the log
> after the network is taken down.
> Tests (and results) [against
> 0.10.2.1|https://github.com/owbear/kafka-network-failure-tests/tree/kafka-network-failure-tests-0.10.2.1]
> Tests (and results) [against
> 0.11.0.0|https://github.com/owbear/kafka-network-failure-tests/tree/kafka-network-failure-tests-0.11.0.0]
