Amazon EMR on EC2 now provides contextual error details that makes it easier to troubleshoot cluster provisioning failures. EMR lets you provision your EMR on EC2 cluster without worrying about managing compute infrastructure or open-source application setup. However, there can be circumstances when your cluster provisioning fails, such as an insufficient EC2 instance capacity error, bootstrap action failure or a VPC-subnet misconfiguration error. With today’s launch, you will now find additional error details in the new EMR console, AWS Command Line Interface (AWS CLI), and the AWS SDK. These additional error details are automatically enabled for all EMR versions and no further action is needed.
Previously when users encountered a provisioning error, such as a bootstrap failure, they would receive an error message that the cluster failed but with no further context. Identifying whether the root cause was an invalid or conflicting bootstrap action or a misconfigured bootstrap source file location took multiple steps. With today’s launch, you will get specific error details for cluster provisioning failures along with detailed root cause, and recommendations to resolve the failure. You can find these details in the Cluster list view in the new console and via APIs.
This feature is available by default in all Amazon EMR on EC2 releases and is available in the regions where Amazon EMR on EC2 is available. To learn more, please visit our EMR error codes documentation.
