Connectio Faild to Kafka with IBM Info Sphere

Question

While trying to read a Kafka topic in a InfoSpfhere Job, I got the error

Kafka_Customer: java.lang.NoClassDefFoundError: org.apache.kafka.clients.consumer.ConsumerRebalanceListener
at com.ibm.is.cc.kafka.runtime.KafkaProcessor.validateConfiguration (KafkaProcessor.java: 145)
at com.ibm.is.cc.javastage.connector.CC_JavaAdapter.initializeProcessor (CC_JavaAdapter.java: 1008)
at com.ibm.is.cc.javastage.connector.CC_JavaAdapter.getSerializedData (CC_JavaAdapter.java: 705)


Kafka_Customer: Java runtime exception occurred: java.lang.NoClassDefFoundError: org.apache.kafka.clients.consumer.ConsumerRebalanceListener (com.ibm.is.cc.kafka.runtime.KafkaProcessor::validateConfiguration, file KafkaProcessor.java, line 145)

I should add the jar file, which is missing, but where and how can I see which version is nedeed?. I could'n find anything after a lot of googling.

Answer 1

kafka-clients JAR versions are backwards compatible down to 0.10.2, however I would assume that the Kafka processors should have this, so you may want to reach out to IBM support
