Resize a cluster
The resize option allows you to add or remove cluster nodes.
To resize a cluster, follow these steps.
Cluster resizing is not supported for HDF clusters.
- Browse to the cluster details.
- Click Actions and select Resize. The cluster resize dialog is displayed.
- Using the +/- controls, adjust the number of nodes for a chosen host group.Note
You can only modify one host group at a time. It is not possible to resize the Ambari server host group.
- Click Yes to confirm the scale-up/scale-down.
While nodes are being added or removed, cluster status changes to “Update In Progress”. Once the operation has completed, cluster status changes back to “Running”.
