I am sure bootstrap.servers is correct. Is there something in Maven or something wrong with Kafka?
Before that, he worked successfully. I added a few Maven or Spark, then something went wrong.
Does anyone know how to solve it?
Here is the kafka code in java
Properties props = new Properties(); props.put("bootstrap.servers", "x.xx.xxx.xxx:9092"); props.put("metadata.broker.list", "x.xx.xxx.xxx:9091, x.xx.xxx.xxx:9092, x.xx.xxx.xxx:9093"); props.put("producer.type", "async"); props.put("batch.size", "500"); props.put("compression.codec", "1"); props.put("compression.topic", topicName); props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer"); props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer"); org.apache.kafka.clients.producer.Producer<String, String> producer = new KafkaProducer<String, String>( props);
