[jira] [Updated] (KAFKA-5585) Failover in a replicated Cluster does not work

     [ https://issues.apache.org/jira/browse/KAFKA-5585?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Bayer updated KAFKA-5585:
--------------------------------
    Description: 
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 Config:
{{props.put(BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
props.put(ACKS_CONFIG, "all");
props.put(BUFFER_MEMORY_CONFIG, 33554432);}}

Consumer Config:
{{ props.put(BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
props.put(GROUP_ID_CONFIG, "a");
props.put(ENABLE_AUTO_COMMIT_CONFIG, "true");
props.put(AUTO_COMMIT_INTERVAL_MS_CONFIG, "1000");
props.put(SESSION_TIMEOUT_MS_CONFIG, "30000");}}
