Preparing Kafka for upgrade

To successfully upgrade Kafka, you must set the protocol version to match the protocol version used by the brokers and clients.

  1. In Ambari Configs, update the following properties:
    • = current_Kafka_version
    • log.message.format.version = current_Kafka_version

    Review the HDP Release Notes for the Apache Kafka version in use with your HDP installation.

  2. Save your changes.
