6 years ago Hi Ahmad,
I put this tutorial to one side for a few days because I was stuck (and was maybe hoping to hear from someone on this site ! ;-) ) but today I have come back to it again hoping with "fresh eyes" and indeed it helped - I was able to spot my mistake immediately.
I had renamed my Scala program from the name you show in the tutorial, "BatchJob" to "BatchJobEx4" but when I tried to run it I was still using the old progamme name you show in the example ie,
./bin/spark-submit --master yarn --deploy-mode cluster --class batch.BatchJob /vagrant/spark-lambda-1.0-SNAPSHOT-shaded.jar
instead of updating it to my new name,
./bin/spark-submit --master yarn --deploy-mode cluster --class batch.BatchJobEx4 /vagrant/spark-lambda-1.0-SNAPSHOT-shaded.jar
When I executed it as renamed it worked perfectly :) so I will now continue with the tutorial and this issue can be closed.

Hi Ahmad, I am not sure if this is the right place to raise issues. I have been following your Lambda Spark course on Pluralsight and I am stuck at the point shown in the title. When I try to execute the statement mentioned,
I get an Exception and my start-up fails.

I have managed to pull the attached logs from the Hadoop webservice running in my VM url here,

Also I've tried to start the application up in Debug Mode (at say port 5005 or 7777 as I found in some online examples) - but when I try starting my Intellij up in Remote Debug Mode I get a Connection Refused error message.
Any help or pointers would be much appreciated. My email is, robbie70@hotmail.com Kind Regards, Robert.
