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

Question

I am manually starting Zookeeper, then Kafka server and finally the Kafka-Rest server with their respective properties file. Next, I am deploying my Spring Boot application on tomcat

In the Tomcat log trace, I am getting the Error org.springframework.context.ApplicationContextException: Failed to start bean 'org.springframework.kafka.config.internalKafkaListenerEndpointRegistry'; nested exception is org.apache.kafka.common.KafkaException: Failed to construct kafka consumer and my application is failing to startup

My Receiver and Sender classes are not annotated with any annotations such as @Component or @Service. Does it make any difference?

@Configuration 
public class InventorySenderConfig

@Configuration 
@EnableKafka 
public class InventoryReceiverConfig

@Component 
public class KafkaConfig

@Configuration 
public class ProducingChannelConfig

@Configuration 
public class ConsumingChannelConfig

@RestController 
public class KafkaWebhookController

@Service("webhookService") 
public class KafkaServiceImpl

@EnableIntegration 
@SpringBootApplication 
@ComponentScan("com.psl.kafka") 
public class SpringKafkaWebhookServiceApplication extends SpringBootServletInitializer

These are my class annotations. Do they look to be OK or I need to change something ?

Do I need to define any Interceptor classes that I have added as config in ProducingChannelConfig, ConsumingChannelConfig as well as InventoryReceiverConfig classes ?

Answer 1

Caused by: java.lang.ClassNotFoundException: org.apache.kafka.common.ClusterResourceListener

You are missing the kafka-clients jar from your class path. What are you using for dependency management? Maven and gradle should put this jar on the class path for you automatically.

Answer 2

Your kafka version is older than it should, your problematic class ClusterResourceListener expect version to be higher than 0.10.1.0, and your version is lower 0.10.0.1.

Just upgrade your kafka jars and it'll fix this issue.

There will be one invocation of onUpdate(ClusterResource) after each metadata response. Note that the cluster id may be null when the Kafka broker version is below 0.10.1.0.
