  spark-submit --class MyClass target/MyJar.jar</p>
  
  <p>The last part of this process is to write it locally and then copy it to s3 as it need to have specific name (can also be written to s3 and mv'ed there, for the sake of the question the error stays the same).</p>
  
  <p>The code compiles and runs but when it get to the code snippet below I get the following error -</p>
