@Subramaniyam KMV In your screenshot take any file / directory PATH and do a list command ..... I am very sure that you will find that it shows ????????? as i mentioned in my previous update. Which indicates a file system corruption on this directory. Example: (You might find ?????????? ?? ?) in the output.
# ls -l /usr/lib/hue/ext/thirdparty/js/moovis

Usually it is best practice to have one thread dedicated to one specific query so that the thread becomes more beneficial for the readers. As your original issue is resolved by Port Forwarding ennoblement to 8081 hence i will suggest you to please mark this thread as Answered (Accepted) and open a new thread for the websocket issue.

@Subramaniyam KMV 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
