Description

I have a thread which once in a while is going to list the topics on the Message Hub. But once in a while, I am getting a :Failed to send SSL Close message.

Any ideas?

Noticed there is another similar defect open: https://issues.apache.org/jira/browse/KAFKA-3702

Not sure if this is the same as that issue. .

Also another post from grokbase: http://grokbase.com/t/kafka/users/1653bm0a02/warn-failed-to-send-ssl-close-message

 

KafkaConsumer<String, String> consumer = new KafkaConsumer<>(getConsumerConfiguration());

try{
   Map<String, List<PartitionInfo>> topics = consumer.listTopics();
   return new ArrayList<String>(topics.keySet());
}
finally{
    if (consumer != null){
          consumer.close();
    }
}

I am getting the warning from consumer.close.

The configuration of the consumer:

• sasl.mechanism = PLAIN
• security.protocol = SASL_SSL
• group.id = consumer1
• ssl.enabled.protocol = TLSv1.2
• ssl.endpoint.identification.algorithm = HTTPS
• ssl.protocol = TLSv1.2
• sasl.jaas.config = org.apache.kafka.common.security.plain.PlainLoginModule required username="USERNAME" password="PASSWORD";
