   If you want to use Apache Storm KafkaSpout with Heron, you can use
   
   `        <dependency>
               <groupId>org.apache.storm</groupId>
               <artifactId>storm-kafka-client</artifactId>
               <version>1.2.2</version>
           </dependency>
   `
   
   But, there's a source file from Apache Storm is missing in the Heron Storm compatibility library which is required by the dependency above. You will need to manually copy `org.apache.storm.utils.Time` class from Apache Storm source tree into your project. We was using Heron 0.17.8 with storm-kafka-client 1.2.2 successfully, but recently rewrote a new one for Heron due to performance issue we found in storm-kafka-client.
