Pay-As-You-Go clusters can be released on the Cluster Management page. Only those with the following statuses can be released:
Before releasing a cluster, you are prompted to confirm the operation. Once the release is confirmed, the following occurs:
- All jobs in the cluster are forcibly terminated.
- If you have selected to save logs to OSS, all current job logs are saved to OSS. This may take several minutes.
- Clusters are released. Depending on their size, this may take seconds or minutes. ECS clusters are billed before they are released.
Warning To save money, make sure to release a cluster before a new billable hour starts.
If you no longer need logs and want to immediately terminate running clusters, perform a forcible release. Logs are not collected and clusters are released directly.
Cluster release failure
Due to system errors or other causes, clusters may fail to be released. If a failure occurs, E-MapReduce starts background protection until the cluster is finally released.
