title: AWS Glue vs AWS EMR - Overwrite S3 files in Spark job
body: <p>I have a Spark job that runs on EMR and reads dataset from S3 (nested json file), join it with other dataset and overwrite few S3 files explicitly.</p>
  
  <p>So, this is not a standard ETL use-case but can AWS Glue provide the same functionality? If yes, is Glue cheaper than EMR?</p>
