Oozie work flow not finding main class

Question

Hello Community,

I am going through this tutorial https://www.cloudera.com/tutorials/setting-up-a-spark-development-environment-with-java.html and I am trying to submit it through Oozie work flow. In Hue I am going to Query > Scheduler > Workflow then dropping Java program to actions and then uploading jar file then adding the main class which is Hortonworks.SparkTutorial.Main. When I click to run the Oozie work flow job I keep getting the error of: "Caused by: java.lang.ClassNotFoundException: Class Hortonwork.SparkTutorial.Main not found". I'm using intelliJ to do this project so I hold down ctrl and hover over Main and it takes me to MANIFEST.MF file and it says Main-Class: Hortonworks.SparkTutorial.Main so I'm getting the main class definition right I feel like. I cannot figure out why it is saying it can't find my class.

Hi @jarededrake , The "ClassNotFoundException: Class Hortonwork.SparkTutorial.Main not found" suggests that in the Java program's main class package name might have a typo (in your workflow definiton), the Hortonwork should be Hortonworks. Can you check that?
