Scale a Cluster In

Administrators can scale a cluster in by removing compute-only nodes or compute nodes with HDFS storage. Master nodes cannot be removed.

To scale a cluster in:
  1. Open the service console. See Access the Service Console for Big Data Cloud.
  2. Click the name of the cluster you want to scale in.

    An overview page with cluster details is displayed. Nodes are listed under Resources.

  3. From the Menu icon menu for the compute node, select Remove Node, and then confirm the action.

    The cluster goes into Maintenance mode and, once the scale-in operation is complete, becomes operational again.
