AWS On Air ft. Amazon EMR Serverless Quick Tip 2
summary
Demo shows running a hive query on EMR Serverless (preview) with EMR release 5.33, using a Hive CLI script on S3 and the Glue Data Catalog table for NOAA GSOD PDS; the job counts about 4,000,000 rows, finishes in ~4 minutes, and writes logs and timeline data to S3 while resources auto‑decommission. It also demonstrates updating initial workers from 9 to 20 to create a warm pool so jobs start instantly and how pre-initialized capacity persists until the application stops.
