Restarting a CDM Cluster

Scenario

After modifying some configurations (for example, disabling user isolation), you must restart the cluster to make the modification take effect.

If you restart a CDM cluster process or VM, jobs that are running will fail, and no jobs can be scheduled during the restart. Exercise caution when performing this operation.

Prerequisites

You have created a CDM cluster.

Restarting a cluster

1. Log in to the CDM console and choose Cluster Management in the left navigation pane.

   Another method: Log in to the DataArts Studio console by following the instructions in Accessing the DataArts Studio Instance Console. On the DataArts Studio console, locate a workspace and click DataArts Migration to access the CDM console.

   The Source column is displayed only when you access the DataArts Migration page from the DataArts Studio console.

2. Locate the row that contains the target cluster, click More in the Operation column, and select Restart from the drop-down list.

3. Select Restart CDM service process or VM restart and click OK.
   • Restart CDM service process: Only the CDM service process is restarted. The cluster VM will not be restarted.
   • VM restart: The service process will be interrupted and VMs in the cluster will be restarted.
