@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 total 20 -rw-r--r-- 5 root root 38 Aug 26 2016 MooVis.js -rw-r--r-- 5 root root 1546 Aug 26 2016 Protovis.Bar.js -rw-r--r-- 5 root root 1356 Aug 26 2016 Protovis.js -rw-r--r-- 5 root root 3497 Aug 26 2016 Protovis.Line.js -rw-r--r-- 5 root root 1268 Aug 26 2016 Protovis.Pie.js

I don't major issue with hue from the attached image. Try curl from the sandbox itself to isolate virtual box port forwarding issue if any?

I'm getting Websocket error on IoT Demo as attached. Kindly help me. iot-demo-websocket-error.png Regards Subramaniyam.KMV

@Subramaniyam KMV 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

The installation of NIFI as a service through HDP 2.5 donen't work. I have installed directly from Apache NIFI website, now it is working.

Hi @Subramaniyam KMV - it looks like James has moved that content and I can't find it immediately. I've messaged him for you to see if he can put it back, but in the meantime it looks like there are instructions to build it yourself if you go further down the tutorial.

It looks like it changed again; this is the valid link as of now for those trying to download it again: https://raw.githubusercontent.com/hortonworks/data-tutorials/df35a19a266eb228d852ae9f0303b505372008ea/tutorials/hdf/realtime-event-processing-in-hadoop-with-nifi-kafka-and-storm/assets/IoT_Lab_Series_DataFlow.xml
