Scale a Cluster Out

Administrators can scale a cluster out by adding compute-only nodes or compute nodes with HDFS storage.

To scale a cluster out:
  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 out.

    An overview page with cluster details is displayed.

  3. From the Menu icon menu for the cluster at the top of the page, select Scale Out.

    The Scale Out window is displayed.

  4. Scale out the cluster as desired:

    • Compute only nodes: Number of compute-only nodes you want to add, between 0 and 5.

    • Compute nodes with HDFS storage: Number of compute and storage nodes you want to add, between 0 and 5.

    • Rebalance HDFS: Select this to rebalance data blocks across storage nodes.

  5. Click Scale Out.

    Nodes are added and the HDFS rebalance operation is performed. During this process the cluster goes into Maintenance mode and, once the scale-out operation is complete, becomes operational again.
