Deleting a Role Instance
Before deleting a role instance that is running, you must first stop it.
To delete a role instance:
- 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.
- Click the Instances tab.
- 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.
- Choose Actions for Selected > Delete. Click Delete again to confirm the deletion.
Deleting a role does not clean up the associated client configurations that have been deployed in your cluster.
