Do you have proper read permission on the JAR "/root/iot-truck-streaming/storm-streaming/target/storm-streaming-1.0-SNAPSHOT.jar" for the user who is running the job?

Can you run the following command to findout if the jar is containing the missing class or not?

jar -tvf  /root/iot-truck-streaming/storm-streaming/target/storm-streaming-1.0-SNAPSHOT.jar  | grep  'TruckEventKafkaExperimTopology'

.

Or can you locate the JAR in your filesystem that contains the following class ?

com.hortonworks.streaming.impl.topologies.TruckEventKafkaExperimTopology
