Verify Kafka Properties

After the upgrade is complete, verify the following properties in Kafka (kafka-broker) using Ambari:

  • inter.broker.protocol.version

  • log.message.format.version

  1. Go to Ambari and locate the inter.broker.protocol.version and log.message.format.version properties.
  2. Verify the values of the properties.
    • inter.broker.protocol.version must be set to the latest Kafka version. For example, inter.broker.protocol.version = 2.1

    • log.message.format.version must be set to the version you set before upgrade. For example, log.message.format.version = 2.0 or 1.1 or 1.0.
  3. If you find any performance degradation, perform proper evaluation and set the value of the log.message.format.version property to the latest Kafka version, which is 2.1, and perform rolling restart for your kafka-broker.
