aws emr terminate-clusters

Shuts down one or more clusters, each specified by cluster ID. Use this command only on clusters that do not have termination protection enabled. Clusters with termination protection enabled are not terminated. When a cluster is shut down, any step not yet completed is canceled and the Amazon EC2 instances in the cluster are terminated. Any log files not already saved are uploaded to Amazon S3 if a --log-uri was specified when the cluster was created. The maximum number of clusters allowed in the list is 10. The command is asynchronous. Depending on the configuration of the cluster, it may take from 5 to 20 minutes for the cluster to terminate completely and release allocated resources such as Amazon EC2 instances
