Luke Chen updated KAFKA-14692:
------------------------------
Fix Version/s: (was: 3.4.1)
> Issues in Zookeeper to KRaft migration docs
> -------------------------------------------
>
> Key: KAFKA-14692
> URL: https://issues.apache.org/jira/browse/KAFKA-14692
> Project: Kafka
> Issue Type: Improvement
> Components: docs, kraft
> Reporter: Mickael Maison
> Assignee: David Arthur
> Priority: Major
> Fix For: 3.5.0
>
>
> Following [https://kafka.apache.org/documentation/#kraft_zk_migration]
> 1) It completely skips the facts that the storage for the new quorum should
> be formatted using the existing cluster id.
> 2) In Provisioning the KRaft controller quorum:
> {{controller.quorum.voters=1@localhost:9093}} should be
> {{controller.quorum.voters=3000@localhost:9093}} as node.id=3000
> 3) When migrating brokers, it states:
> {code:java}
> # Don't set the IBP, KRaft uses "metadata.version" feature flag
> # inter.broker.protocol.version=3.4
> # Keep the migration enabled
> zookeeper.metadata.migration.enable=true
> # Remove ZooKeeper client configuration
> # zookeeper.connect=localhost:2181
> {code}
> However if I do that, my brokers fails to restart and print:
> {code:java}
> org.apache.kafka.common.config.ConfigException: If using
> zookeeper.metadata.migration.enable in KRaft mode, zookeeper.connect must
> also be set.
> {code}
> 4) When disabling zookeeper.metadata.migration.enable or keeping
> zookeeper.connect to get past this step, when brokers restart they print a
> lot of error messages:
> {code:java}
> org.apache.kafka.common.errors.InvalidRequestException: Received request api
> key LEADER_AND_ISR which is not enabled
> [2023-02-08 12:06:25,776] ERROR Exception while processing request from
> 192.168.1.11:9092-192.168.1.11:57210-107 (kafka.network.Processor)
> {code}
