Luke Chen created KAFKA-14695: --------------------------------- Summary: broker will get LEADER_AND_ISR is not enabled error while ZK migrating to KRaft Key: KAFKA-14695 URL: https://issues.apache.org/jira/browse/KAFKA-14695 Project: Kafka Issue Type: Bug Components: kraft Affects Versions: 3.4.0 Reporter: Luke Chen Assignee: Luke Chen
Following the docs here: [https://kafka.apache.org/documentation/#kraft_zk_migration] During the step "Migrating brokers to KRaft", after migrating, the broker will get a lot of error: {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} It blocks further migration. This can be workaround by explicitly setting the listener host name. That is, instead of setting listeners value like this (also the default value) _listeners=PLAINTEXT://:9092_ It should be set as: _listeners=PLAINTEXT://localhost:9092_ Will update the doc first, to unblock other users trying to migrate from ZK to Kraft, then investigating why this happened. -- This message was sent by Atlassian Jira (v8.20.10#820010)
