---------------------------------------

             Summary: KafkaConsumer.close() may block indefinitely
                 Key: KAFKA-3540
                 URL: https://issues.apache.org/jira/browse/KAFKA-3540
             Project: Kafka
          Issue Type: Bug
            Reporter: Oleg Zhurakousky


KafkaConsumer API doc states 
{code}
Close the consumer, waiting indefinitely for any needed cleanup. . . . 
{code}

That is not acceptable as it creates an artificial deadlock which directly 
affects systems that rely on Kafka API essentially rendering them unavailable.
