KafkaSpout is a spout implementation that integrates with Storm and can read from Kafka clusters and then emit those messages as tuples within the Storm ecosystem. Here’s a sample code to create a simple KafkaSpout -
// ZooKeeper connection string
BrokerHosts hosts = new ZkHosts(zkConnString);
//Creating SpoutConfig Object
SpoutConfig spoutConfig = new SpoutConfig(hosts,
topicName, "/" + topicName UUID.randomUUID().toString());
//convert the ByteBuffer to String.
spoutConfig.scheme = new SchemeAsMultiScheme(new StringScheme());
//Assign SpoutConfig to KafkaSpout.
KafkaSpout kafkaSpout = new KafkaSpout(spoutConfig);
