Here is the consumer config

props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, ip + ":" + KafkaConfiguration.KAFKA_PORT);
props.put(ConsumerConfig.GROUP_ID_CONFIG, KafkaConfiguration.CONSUMER_PRIVATE_GROUP_ID + "-" + i + "-" + KafkaConfiguration.KAFKA_HOST);
props.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName());
props.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, ByteArrayDeserializer.class.getName());
props.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");
props.put(ConsumerConfig.FETCH_MIN_BYTES_CONFIG, 1);
props.put(ConsumerConfig.FETCH_MAX_WAIT_MS_CONFIG, 10);
props.put(ConsumerConfig.MAX_POLL_RECORDS_CONFIG, 60000);
props.put(ConsumerConfig.MAX_POLL_INTERVAL_MS_CONFIG, "600000");
props.put(ConsumerConfig.REQUEST_TIMEOUT_MS_CONFIG, "1000");
props.put(ConsumerConfig.METADATA_MAX_AGE_CONFIG, "1000");
props.put(ConsumerConfig.RECONNECT_BACKOFF_MS_CONFIG, "500");
props.put(ConsumerConfig.RECONNECT_BACKOFF_MAX_MS_CONFIG, "8000");

props.put(ConsumerConfig.ENABLE_AUTO_COMMIT_CONFIG, "false");
props.put(CommonClientConfigs.SECURITY_PROTOCOL_CONFIG, "SASL_PLAINTEXT");
props.put(SaslConfigs.SASL_MECHANISM, "PLAIN");
props.put(SaslConfigs.SASL_JAAS_CONFIG, "org.apache.kafka.common.security.plain.PlainLoginModule required username=\"" + "consumer" + "-" + position + "-" + current_ip + "\" password=\"consumer-secret\";");```

Detected code, here are some useful tools:

[WARNING] The code couldn't end properly...

Problematic source code:

props.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, ip + ":" + KafkaConfiguration.KAFKA_PORT);```

Your question has been closed due to inactivity.

If it was not resolved yet, feel free to just post a message below
to reopen it, or create a new thread.

Note that usually the reason for nobody calling back is that your
question may have been not well asked and hence no one felt confident
enough answering.

When you reopen the thread, try to use your time to improve the quality
of the question by elaborating, providing details, context, all relevant code
snippets, any errors you are getting, concrete examples and perhaps also some
screenshots. Share your attempt, explain the expected results and compare
them to the current results.

Also try to make the information easily accessible by sharing code
or assignment descriptions directly on Discord, not behind a link or
PDF-file; provide some guidance for long code snippets and ensure
the code is well formatted and has syntax highlighting. Kindly read through
https://stackoverflow.com/help/how-to-ask for more.

With enough info, someone knows the answer for sure 👍
