title: Is it possible to update only part of a Glue Job using AWS CLI?
body: <p>I am trying to include in my CI/CD development the update of the <code>script_location</code> and only this parameter. AWS is asking me to include the required parameters such as <code>RoleArn</code>. How can I only update the part of the job configuration I want to change ?</p>
  
  <p>This is what I am trying to use</p>
  
  <pre><code>aws glue update-job --job-name &lt;job_name&gt; --job-update Command="{ScriptLocation=s3://&lt;s3_path_to_script&gt;}
  </code></pre>
  
  <p>This is what happens :</p>
  
  <p><code>An error occurred (InvalidInputException) when calling the UpdateJob operation: Command name should not be null or empty.</code></p>
  
  <p>If I add the default Command Name <code>glueetl</code>, this is what happens :</p>
  
  <p><code>An error occurred (InvalidInputException) when calling the UpdateJob operation: Role should not be null or empty.</code></p>
