Kafka producer future get timeout

I'm trying to handle failures in case the producer fails to send message to Kafka :

try {
    Future<RecordMetadata> res = producer.send(new ProducerRecord<>(topic, msg.key(), msg));
    log.info("Waiting for confirmation from kafka for message : \n {}",msg.toString());
    record = res.get(30,TimeUnit.SECONDS);
    log.info("Successfully produced message : msg")
} catch (InterruptedException | ExecutionException | TimeoutException e) {
    log.error("The following message wasnt sent to kafka because of an error : {}", msg.toString(), e);
}

When I try to produce a message to a topic that doesn't exist I'm seeing the following error :

java.util.concurrent.ExecutionException: org.apache.kafka.common.errors.TimeoutException: Topic just_fake_topic  not present in metadata after 60000 ms.

    Caused by: org.apache.kafka.common.errors.TimeoutException: Topic just_fake_topic not present in metadata after 60000 ms.

I'm getting the timeout after 60 seconds not 30 seconds as I configured in the get method of the future object.

I tried also to configure metadata.max.idle.ms=30000 and max.block.ms=30000 in my kafka.properties because I was also getting the following warning for about 5 minutes but it didn't help:

2020-06-28 14:31:26.009  WARN 10291 --- [ad | producer-1] org.apache.kafka.clients.NetworkClient   : [Producer clientId=producer-1] Error while fetching metadata with correlation id 695 : {just_fake_topic =UNKNOWN_TOPIC_OR_PARTITION}

Any idea why ?

The exception might be getting thrown from the Kafka network thread.

Maybe provide a callback as a second parameter for send. Note: callback will run on the kafka network thread.
