How do I resolve "EC2 is out of capacity" or "EC2 QUOTA EXCEEDED" errors in Amazon EMR?
I want to resolve "EC2 is out of capacity" or "EC2 QUOTA EXCEEDED" errors in Amazon EMR.
Resolution
Amazon EC2 is out of capacity
You receive the "EC2 is out of capacity" error when the specified Availability Zone can't provision the requested Amazon Compute Cloud (Amazon EC2) instance types for your Amazon EMR cluster.
To resolve the "EC2 is out of capacity" error, take the following actions:
- After you receive the error, wait a few minutes. Then, relaunch the cluster or use automatic retries across different Availability Zones. Capacity availability is dynamic and changes frequently.
- Change your Amazon EC2 instance type and Availability Zone.
- Plan and configure instance fleets for your Amazon EMR cluster so that you can flexibly select instance types. Choose your preferred capacity provisioning strategy to balance between cost and available capacity. Before you use instance fleets in your cluster, see Considerations for working with instance fleets.
- Use Reserved Instances for long-term and predictable workloads.
- Use Dedicated Instances for specialized requirements.
Amazon EC2 Quota exceeded
You receive the "EC2 QUOTA EXCEEDED" error when you reach your Amazon EC2 service quota for your specified AWS Region.
To resolve this error, complete the following steps:
- Open the Service Quotas console.
- Choose Dashboard and then choose Amazon Elastic Compute Cloud (Amazon EC2).
- Review your current service quotas.
Note: Only running instances count toward service quotas, and the quota varies by Region. The quotas restrict the number of running instances based on instance count, instance type quotas, and instances that are allowed for each Region. - If you need additional Amazon EC2 resources, then request a service quota increase.
- Monitor your service quota usage.
Best practices
Use the following best practices:
- Implement multi Availability Zone retry strategies.
- Plan your capacity needs in advance. Then, review and compare Amazon EC2 instance type capabilities before you select other options.
- Carefully choose your subnet. The subnet you choose determines your Availability Zone.
