Kafka

You must cleanup metadata on broker hosts after migrating the Ambari-managed HDP cluster to CDP Private Cloud Base.

Cleanup Metadata on Broker Hosts
  1. On each Broker host, remove $log.dirs/meta.properties file from Kafka broker hosts. For example,
    #mv /grid/0/kafka-logs/meta.properties /tmp.

    Remove ${log.dirs}/meta.properties file from Kafka broker.

    If the Kafka log.dirs property points to /kafka-logs, then the command is

    #mv /kafka-logs/meta.properties /tmp

  2. Set the Kafka port value. For more information, see Change Kafka Port Value.
  3. Enable kerberos.auth.enable. For more information, see Kafka cluster Kerberos.
  4. Start the Kafka service.
