What's New in Apache Kafka

Zookeeper TLS/SSL support for Kafka

A new Kafka configuration parameter, Enable Secure Connection to ZooKeeper is added. This property enables or disables secure communication between Kafka and Zookeeper. The property is enabled by default, however, it will only take effect if the Enable TLS/SSL for ZooKeeper property is also enabled for the dependent ZooKeeper service. For more information, see the related Zookeeper documentation and Kafka documentation.

Enable Delegation Tokens is set to true by default

The Enable Delegation Tokens property that enables and disables delegation token based authentication is set to true by default. Note however, that this does not by default enable the feature itself as delegation tokens require Kerberos authentication to function.

For more information, see Enable or Disable Authentication with Delegation Tokens.
