Subject [jira] [Commented] (KAFKA-5585) Failover in a replicated Cluster does not work
Date Wed, 12 Jul 2017 13:41:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-5585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16083991#comment-16083991

M. Manna commented on KAFKA-5585:
---------------------------------

Jinx or not, I was doing some PoC test on reliability on Windows. Somewhat similar issues
to what's been reported here (i guess however, my linger.ms and backoff.ms need to be adjusted
properly)

Two topics *z1* (partitions 1 repfactor 3) and *z3* (partitions 3 repfactor 3) should be created
beforehand. Attached files are
1) Source code for my stress testing - Need to create a project with *Log4j *- test_project_files.zip
2) Test results excel sheet.

> Failover does not work in a cluster with 3 nodes and a replicated topic with factor 3.
> You can reproduce it als follows: Setup 3 Kafka Nodes and 1 Zookeeper. Than create a
topic with factor 3. Start a consumer. Stop a node. Write to the topic. Now you get warnings
that the client can not connect to a broker. The consumer does not receive any messages.
> The same setup works like a charm with 0.10.2.1.
> Broker Config:
> {{broker.id=1
> listeners=PLAINTEXT://:9091
> log.dirs=cluster/logs/node-1
> broker.id=2
> listeners=PLAINTEXT://:9092
> log.dirs=cluster/logs/node-2
> broker.id=3
> listeners=PLAINTEXT://:9093
> log.dirs=cluster/logs/node-3}}
> Rest of the config is from the distribution.
> Producer and consumer config: see attached files
