    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}

    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.
