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.
- In Ambari Configs, update the following properties in the server.properties file:
inter.broker.protocol.version = 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.
- Save your changes.
