ZooKeeper
Deploying new or using existing Kafka clusters running in ZooKeeper mode is deprecated. Support for ZooKeeper-based Kafka clusters will be removed in a future release. Cloudera recommends the following:

  • Deploy all new Kafka clusters in KRaft mode.

  • Migrate existing ZooKeeper-based clusters to KRaft following an upgrade to Cloudera Runtime 7.3.2.

    This is the only version where migration is possible. Neither previous or future major, minor, and maintenance versions support migration.

    For additional information, see the following resources:
MirrorMaker (MM1)

--zookeeper
The --zookeeper option is only supported for the kafka-configs tool and should be only used when updating SCRAM Credential configurations. The --zookeeper option is either deprecated in or removed from other Kafka command line tools. Cloudera recommends that you use the --bootstrap-server option instead.
