I’m getting “Topic not present in metadata after 60000 ms” message on some computers

Here’s my program

                inTopic = args[++i];
            } else if (args[i].equals("--outtopic")) {
                if (i == args.length - 1) {
                outTopic = args[++i];
            } else if (args[i].equals("--bootstrap-servers")) {
                if (i == args.length - 1) {
                bootstrapServers = args[++i];
            } else {

        final Consumer<Long, String> consumer;
        if (inTopic.equals("stdin")) {
            consumer = null;
        } else {
            consumer = createConsumer(inTopic, bootstrapServers);
        final Producer<Long, String> producer;
        if (outTopic.equals("stdout")) {
            producer = null;
        } else {
            producer = createProducer(bootstrapServers);

        while (true) {
            if (!run(consumer, producer, inTopic, outTopic)) {
        if (consumer != null)
        if (producer != null)

I run it on Windows and Linux. On some computers it runs fine, but on other computers, specifically a Linux machine which is not the kafka machine, it consistently gives me this error:

Exception sending message: org.apache.kafka.common.errors.TimeoutException: Topic outtopic not present in metadata after 60000 ms.

This happens, of course, when trying to send a message in the run() function, specifically in the sentence RecordMetadata metadata = sent.get().

This kafka installation allows creation of new topics automatically. In fact, if I enter a new name in the –outtopic parameter, even when sending the message fails, the topic is created.

Any clues why? What am I missing in the configuration?

Thank you




This seems to be an internal IP. Check if the clients where you cannot access are within its network range i.e. whether they can access this IP.

Try doing a telnet from your client machine..

telnet 9092

If you are not able to telnet then give the IP which can be accessed by your clients and ensure the same in the advertised.listeners also.

Also check your advertised.listeners config. When we connect to a url given in the bootstrap.servers that typically should par with those in the advertised.listeners configuration.

Topic metadata not present means that your client is unable to fetch any information about the given topic i.e. it cannot get metadata through the given bootstrap.servers property.
