View the cluster list
Log on to the EMR console and click EMR on ECS in the left-side navigation pane.
In the top navigation bar, select the region where your cluster resides and select a resource group.

On the EMR on ECS page, click the name of the cluster you want to inspect.
On the Basic Information tab, review the cluster details. The tab is organized into four sections. The fields displayed vary based on the configuration you specified when creating the cluster.
Section Contents Cluster Information Cluster name, cluster ID, creation time, high availability status, and billing method. Software Information Cluster version, cluster type, installed software, and Hive metadata type. Network Hardware Zone, virtual private cloud (VPC), and hardware configurations. Security Key pair, Elastic Compute Service (ECS) instance role, security group, and cluster service role.
