This topic introduces the concepts of expiration and overdue payment of an E-MapReduce (EMR) cluster. This topic also describes the status of a cluster after the cluster has expired or has an overdue payment, and the operations that you need to perform on the cluster.
Only subscription clusters can expire.
- If an ECS instance of the cluster expires, the ECS instance enters the Stopped state but continues to run for 15 days. If you do not renew the instance within this period of time, the instance stops running but is retained for another 15 days. If you still fail to renew the instance, the instance is automatically released.
- If the EMR service of a cluster expires, you cannot perform operations on the cluster in the EMR console or call EMR API operations. You also cannot use automated O&M services, including monitoring and alerting.
Only pay-as-you-go clusters can have an overdue payment.
If your Alibaba Cloud account does not have sufficient funds, such as vouchers or cash, to cover the fees that are generated by your cluster in the previous hour, the cluster enters the Overdue state.
After a cluster enters the Overdue state, the ECS instances of the cluster continue to run for 15 days. If you do not top up your account within this period of time, the cluster enters the Revoked state and the instances are retained for another 15 days. If you still fail to top up your account, the cluster is automatically released and all data in the cluster is lost. If a cluster has an overdue payment, you cannot use the EMR service of the cluster. The EMR service can be recovered only after you settle the overdue payment.
The expiration or overdue payment of a cluster does not affect the performance of another cluster. For example, if you have a pay-as-you-go cluster with an overdue payment and a subscription cluster that does not expire, the subscription cluster can work as expected.
