I am using default server.properties/zookeeper.properties files provided by Kafka framework.
I am trying to create a simple NodeJS app which would send messages to Producer and consume them.
Below is NodeJS code.
config.js
module.exports = {
kafka_topic: 'catalog',
kafka_server: 'localhost:9092',
};
nodejs-producer.js
const kafka = require('kafka-node');
const config = require('./config');
try {
// set the desired timeout in options
const options = {
timeout: 5000,
};
const Producer = kafka.Producer;
const client = new kafka.KafkaClient({kafkaHost: config.kafka_server, requestTimeout: 5000});
const producer = new Producer(client);
const kafka_topic = config.kafka_topic;
let payloads = [
{
topic: kafka_topic,
messages: 'This is test message'
}
];
producer.on('ready', async function() {
let push_status = producer.send(payloads, (err, data) => {
if (err) {
console.log(err.toString());
console.log('[kafka-producer -> '+kafka_topic+']: broker update failed');
} else {
console.log(data.toString());
console.log('[kafka-producer -> '+kafka_topic+']: broker update success');
}
});
});
producer.on('error', function(err) {
console.log(err);
console.log('[kafka-producer -> '+kafka_topic+']: connection errored');
throw err;
});
}
catch(e) {
console.log(e);
}
kafka version = 2.8.0 kafka-node version = 5.0.0
I am getting the error - Error: LeaderNotAvailable
How to fix this? I tried playing with different values in server.properties file like advertised.listeners but didn't get solution.
