Upgrade Apache Kafka

To upgrade Apache Kafka 2.5.3, you must stop all of the Kafka brokers before you start the upgrade.

  1. Shut down the current Kafka daemon, switch to the new version, and start the daemon:

    su - kafka -c "/usr/hdp/current/kafka-broker/bin/kafka stop"
       hdp-select set kafka-broker
       su - kafka -c "usr/hdp/current/kafka-broker/bin/kafka start"
  2. To verify that the Kafka daemon joined the cluster, create a topic and submit it to Kafka. Send a test message for that topic, and then validate that it was received by a consumer.

  3. If the upgrade process fails, follow the steps in "Downgrading Kafka" to return to your previous version of Kafka.
