These properties are used to configure tKafkaConnection running in the Standard Job framework.

The Standard tKafkaConnection component belongs to the Internet family.

The component in this framework is available when you are using one of the Talend solutions with Big Data.

Basic settings

Version

Select the version of the Kafka cluster to be used.

Zookeeper quorum list

Enter the address of the Zookeeper service of the Kafka cluster to be used.

The form of this address should be hostname:port. This information is the name and the port of the hosting node in this Kafka cluster.

If you need to specify several addresses, separate them using a comma (,).

Broker list

Enter the addresses of the broker nodes of the Kafka cluster to be used.

The form of this address should be hostname:port. This information is the name and the port of the hosting node in this Kafka cluster.

If you need to specify several addresses, separate them using a comma (,).

Use SSL/TLS

Select this check box to enable the SSL or TLS encrypted connection.

Then you need to use the tSetKeystore component in the same Job to specify the encryption information.

For further information about tSetKeystore, see tSetKeystore.

This check box is available since Kafka 0.9.0.1.

Use Kerberos authentication

If the Kafka cluster to be used is secured with Kerberos, select this check box to display the related parameters to be defined:

  • 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. It 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 check box and enter the custom access path.

    If you leave this check box 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 check box and enter the custom access path to the Kerberos configuration file.

    If you leave this check box 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.

For further information about how a Kafka cluster is secured with Kerberos, see Authenticating using SASL.

This check box is available since Kafka 0.9.0.1.

Advanced settings

tStatCatcher Statistics

Select this check box to gather the processing metadata at the Job level as well as at each component level.

Usage

Usage rule

This component is used standalone to create the Kafka connection that the other Kafka components can reuse.
