[jira] [Commented] (KAFKA-10363) Broker try to connect to a new
cluster when there are changes in zookeeper.connect properties
[ https://issues.apache.org/jira/browse/KAFKA-10363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17178634#comment-17178634 ]
Rens Groothuijsen commented on KAFKA-10363:
-------------------------------------------
One possible workaround is to update the broker's existing kafka-logs/meta.properties file with the expected ID, or remove it so that it will be regenerated upon next restart.

> Key: KAFKA-10363
> URL: https://issues.apache.org/jira/browse/KAFKA-10363
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 2.4.0, 2.3.1
> Environment: 3 Kafka brokers (v2.3.1, v2.4.0) with Zookeeper cluster (3.4.10)
> Ubuntu 18.04 LTS
> Reporter: Alexey Kornev
> Priority: Critical
>
> We've just successfully set up a Kafka cluster consists of 3 brokers and faced with the following issue: when we change order of zookeeper servers in zookeeper.connect property in server.properties files and restart Kafka broker then this Kafka broker tries to connect to a new Kafka cluster. As a result, Kafka broker throws an error and shutdown.
> For example, config server.properties on first broker:
> {code:java}
> broker.id=-1
> ...
> zookeeper.connect=node_1:2181/kafka,node_2:2181/kafka,node_3:2181/kafka
> {code}
> We changed it to
> {code:java}
> broker.id=-1
> ...
> zookeeper.connect=node_2:2181/kafka,node_3:2181/kafka,node_1:2181/kafka {code}
> and restart Kafka broker.
> Logs:
> {code:java}

> {code}

> As you can see here, this broker tries to connect to Cluster with ID _5_d5S6HeQBWf0ZzwQ6TjRA_, but other brokers are connected to Cluster with ID _OhWuEGMeQHe66HP74rurRA_.
> If we bring back the order of zookeeper servers in the config file then Kafka broker starts normally and connects to an existing cluster.
> This issue blocks us from adding new nodes to the cluster and removes the old ones.
> Cluster details:
> * 3 Kafka nodes cluster running 2.3.1 (also reproduced on 2.4.0)
> * 3 Zookeeper node cluster running 3.4.10
