Managing Cloudera Data Science Workbench Hosts

This topic describes how to add and remove hosts on a Cloudera Data Science Workbench deployment.

Adding a Worker Node

For instructions on how to add a worker node to Cloudera Data Science Workbench, see Installing Cloudera Data Science Workbench on a Worker Node.

To remove a worker node:

On the master node, run the following command to delete the worker node:
```
kubectl delete node <worker_node_domain_name>
```
On the master node, run the following command to disable the worker node on the NFS server:
```
cdsw disable <IP_address_worker_node>
```
3. Reset the worker node.
```
cdsw reset
```

Cloudera Data Science Workbench allows you to change the domain of the web console.

Open /etc/cdsw/config/cdsw.conf and set the DOMAIN variable to the new domain name.
```
DOMAIN="new-cdsw.company.com"
```
Run the following commands to have the new domain name go into effect.
```
cdsw reset
cdsw init
```
