Qlik Talend Data Integration: Error while using tSetKeystore component with kafka components

A Job design is presented below:

tSetKeystore: set the Kafka truststore file.

tKafkaConnection, tKafkaInput: connect with Kafka Cluster as a Consumer and transmits messages.

However, while running the Job, an error exception occurred under the tKafkaInput component.

org.apache.kafka.common.KafkaException: Failed to construct kafka consumer

Resolution

Make sure to execute the tSetKeyStore component prior to the Kafka components to enable the Job to locate the certificates required for the Kafka connection. To achieve this, connect the tSetKeystore component to tkafkaConnection using an OnSubjobOK link, as demonstrated below:

For more detailed information on trigger connectors, specifically OnSubjobOK and OnComponentOK, please refer to this KB article: What is the difference between OnSubjobOK and OnComponentOK?.
