I got this when I tried to create the DB: "Before you run your first query, you need to set up a query result location in Amazon S3. Learn more"
1. Navigate to S3
2. Create a bucket
3. Create a folder in the bucket created above
4. Back in Athena, go to Settings. Type in the S3 path. Example: s3://query-results-bucket/folder/ and click on Save
5. Run the query again
