    For a list of endpoints associated with these Regions, see Service endpoints.

  • The default timeout for a job run is 12 hours. You can change this setting with the executionTimeoutMinutes property in the startJobRun API or the Amazon SDK. You can set executionTimeoutMinutes to 0 if you want your job run to never time out. For example, if you have a streaming application, you can set executionTimeoutMinutes to 0 to allow the streaming job to run continuously.

  • The billedResourceUtilization property in the getJobRun API shows the aggregate vCPU, memory, and storage that Amazon has billed for the job run. Billed resources include a 1-minute minimum usage for workers, plus additional storage over 20 GB per worker. These resources don't include usage for idle pre-initialized workers.

  • Without VPC connectivity, a job can access some Amazon Web Service endpoints in the same Amazon Web Services Region. These services include Amazon S3, Amazon Glue, Amazon CloudWatch Logs, Amazon KMS, Amazon Security Token Service, Amazon DynamoDB, and Amazon Secrets Manager. You can enable VPC connectivity to access other Amazon Web Services through Amazon PrivateLink, but you aren't required to do this. To access external services, you can create your application with a VPC.

  • EMR Serverless doesn't support HDFS. The local disks on workers are temporal storage that EMR Serverless uses to shuffle and process data during job runs.

  • EMR Serverless doesn't support the existing emr-dynamodb-connector.
