I think maybe your understanding is a little wrong. You're not supposed to create a KafkaConsumer manually.

Use the KafkaSpout (or Trident spout) from the org.apache.storm:storm-kafka-client module. You can find guides on how to use it in the Storm documentation at https://storm.apache.org/releases/2.0.0-SNAPSHOT/storm-kafka-client.html , and example code at https://github.com/apache/storm/tree/master/examples/storm-kafka-client-examples .
