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

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.

>                 URL: https://issues.apache.org/jira/browse/KAFKA-5585
>             Project: Kafka
>          Issue Type: Bug
>          Components: core
>    Affects Versions:
>         Environment: Linux, Mac OSX
>            Reporter: Thomas Bayer
>         Attachments: SimpleConsumer.java, SimpleProducer.java
> 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
> 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
