Today, we are excited to announce that Amazon EMR now publishes events for insufficient instance capacity. This launch makes it simpler for customers to troubleshoot EC2 instance capacity issues by providing them an easy way to view which instance types have insufficient capacity. Additionally, customers can use these events to create rules to be notified when there is insufficient instance capacity, as well as react to changes in their EMR cluster. These new events are automatically enabled for both current and earlier Amazon EMR on EC2 releases and no further action is needed.
Amazon EMR lets you provision and scale your EMR on EC2 cluster without having to worry about managing compute infrastructure or open-source application setup. However, there can be circumstances when your cluster fails to provision or your clusters fails to scale-up due to insufficient EC2 instance capacity. With this launch, EMR will publish an event for insufficient instance capacity to the new EMR console. Additionally, EMR will also start sending the insufficient instance capacity error events to Amazon EventBridge included as part of the EMR Instance Fleet Resize and EMR Instance Group events.
Insufficient instance capacity error events are available by default for both current and earlier Amazon EMR on EC2 releases and is available in the regions where Amazon EMR on EC2 is available. You can get started by monitoring insufficient instance capacity error events in the new EMR console or Amazon EventBridge. For more information, please read our event documentation and review our insufficient instance capacity error event tutorial.
