Configuring Talend Data Stewardship to support Kerberized Apache Kafka

You can set up Talend Data Stewardship to work with an external Kerberized Apache Kafka.

Before you begin

Make sure you have the following resources:

  • Client Kerberos configuration file: krb5.conf
  • JAAS Kerberos configuration file: kafka_client_jaas.conf
  • Kerberos keytab file: hostname.keyTab
  • JKS truststore: krb5.truststore

Procedure

  1. Create an <installation_folder>\kafka-kerberos\ directory and copy the below files into it:
    • krb5.conf
    • kafka_client_jaas.conf
    • hostname.keyTab
    • krb5.truststore
  2. Open the <installation_folder>\kafka-kerberos\kafka_client_jaas.conf file and check that the keyTab property is as below:
    keyTab=<install_dir>\kafka-kerberos\hostname.keyTab
  3. Edit the <installation_folder>\tds\config\data-stewardship.properties file to add or edit the following lines:
    kafka.ssl.truststore.location=<install_dir>\kafka-kerberos\krk5.truststore
    kafka.ssl.truststore.password=<your_truststore_password>
    spring.cloud.stream.kafka.binder.configuration.ssl.truststore.location=${kafka.ssl.truststore.location}
    spring.cloud.stream.kafka.binder.configuration.ssl.truststore.password=${kafka.ssl.truststore.password}
    spring.kafka.properties.ssl.truststore.location=${kafka.ssl.truststore.location}
    spring.kafka.properties.ssl.truststore.password=${kafka.ssl.truststore.password}
    java.security.auth.login.config=<install_dir>\kafka-kerberos\kafka_client_jaas.conf
    java.security.krb5.conf=<install_dir>\kafka-kerberos\krb5.conf
