title: Have AWS Athena assume role for accessing external S3 bucket
body: <p>I set up an Athena table via Glue in my account that is supposed to query the data in my friends account. My friend created an IAM role I can assume that has permission to access the S3 data.</p>
  
  <p>My Athena queries error out complaining that they don't have permission to access the S3 bucket. Is there a way to make Athena assume the role so it can get to the S3 bucket?</p>
