Deleting a Role Instance

  Note:

Before deleting a role instance that is running, you must first stop it.

To delete a role instance:

  1. Under the Services tab, click the service instance that contains the role instance you want to delete. For example, click the HDFS service instance if you want to delete a DataNode role instance.
  2. Click the Instances tab.
  3. Select the role instance you want to delete. Note that if the role is not already stopped, you must stop it before you can delete it.
  4. Choose Actions for Selected > Delete. Click Delete again to confirm the deletion.
  Note:

Deleting a role does not clean up the associated client configurations that have been deployed in your cluster.
