title: AWS Glue output file name
body: <p>I am using AWS to transform some JSON files. I have added the files to Glue from S3. The job I have set up reads the files in ok, the job runs successfully, there is a file added to the correct S3 bucket. The issue I have is that I cant name the file - it is given a random name, it is also not given the .JSON extension. </p>
  
  <p>How can I name the file and also add the extension to the output?</p>
