java.lang.ClassNotFoundException

tip

This might be an issue with the file location in the Spark submit command. Try it with "spark-submit --master spark://master:7077 hello_world_from_pyspark.py {file location}"

tip

Check if you've set a name in Application -> Run. If you didn't, the generated XML is gonna have missing information and then this exception will be thrown.

You have a different solution? A short tip here would help you and many other users who saw this issue last week.
