JAAS configuration path: enter the path, or browse to the JAAS configuration file to be used by the Job to authenticate as a client to Kafka.
This JAAS file describes how the clients, the Kafka-related Jobs in terms of Talend , can connect to the Kafka broker nodes, using either the kinit mode or the keytab mode. The JAAS file must be stored in the machine where these Jobs are executed.
Talend , Kerberos or Kafka does not provide this JAAS file. You need to create it by following the explanation in Configuring Kafka client depending on the security strategy of your organization.
Kafka brokers principal name: enter the primary part of the Kerberos principal you defined for the brokers when you were creating the broker cluster. For example, in this principal kafka/kafka1.hostname.com@EXAMPLE.COM, the primary part to be used to fill in this field is kafka.
Set kinit command path: Kerberos uses a default path to its kinit executable. If you have changed this path, select this checkbox and enter the custom access path.
If you leave this checkbox clear, the default path is used.
Set Kerberos configuration path: Kerberos uses a default path to its configuration file, the krb5.conf file (or krb5.ini in Windows) for Kerberos 5 for example. If you have changed this path, select this checkbox and enter the custom access path to the Kerberos configuration file.
If you leave this checkbox clear, a given strategy is applied by Kerberos to attempt to find the configuration information it requires. For details about this strategy, see the Locating the krb5.conf Configuration File section in Kerberos requirements.
