Adding a Cloudera Base on premises cluster as a Classic Cluster

Register a Cloudera Base on premises cluster as a classic cluster using Cloudera Manager so that you can use the Base cluster in your hybrid environment as the Data Lake.

All the clusters must meet the requirements identified in Prerequisites for adding classic clusters.

Log in to Cloudera Management Console.
Click Classic Clusters.
On the Classic Clusters page, click ADD CLUSTER.
In the Add Cluster dialog box, navigate to the Cloudera Base on premises tab and enter the following details:
1. If your cluster is not reachable by a public network, click “My cluster is accessible only in my private network”.
2. Cloudera Manager IP address - Enter the IP address of the Cloudera Manager of the Cloudera Base on premises cluster. The Cloudera Management Console uses this IP address to identify the cluster for registration purposes.
3. Cloudera Manager Port - Enter the port of the Cloudera Manager of the Cloudera Base on premises cluster.
4. Data center - Enter a unique data center name for the Cloudera Base on premises cluster.
5. Select the My cluster runs on HTTPS option if the Cloudera Base on premises cluster uses HTTPS.
6. Clear the Register KNOX endpoint (Optional) option, if selected.
7. Click CONNECT.
The Cloudera Management Console acquires the configuration details from Cluster Connectivity Manager service. After Cloudera successfully connects to your new cluster (which should take no more than 5 minutes), it will highlight Step 2.
On the Classic Clusters page, click Files in the Step 2 pane.
Follow the instructions in the Setup Connectivity Client dialog box. You need to download the jumpgate-agent rpm file and the cluster_connectivity_setup_files zip file onto Cloudera Manager host in your new cluster:
1. In the command line interface, copy the jumpgate-agent RPM and cluster_connectivity_setup_files.zip to the Cloudera Manager host.
2. Unzip the cluster_connectivity_setup_files file. Inside this zip file there is a script install.sh.
3. SSH to the Cloudera Manager host.
4. Install the jumpgate-agent rpm using:
```
yum --nogpgcheck localinstall < 
downloaded-jumpgate-agent-rpm >
```
5. Run install.sh by using ./install.sh command.
6. Check service status to see if the agent has been connected:
```
systemctl status jumpgate-agent.service
```
  note
  If you regenerate the script files, you cannot use the previously downloaded cluster_connectivity_setup_files.zip file because the file is no longer valid.
On the Classic Clusters page, click Test Connection in the Step 2 pane to verify whether the connection is successful.
Click Register in the Step 3 pane.
In the Cluster Details dialog box, enter the Cloudera Manager credentials that have Admin access to Cloudera Manager and the cluster services.
Click CONNECT.
To complete the registration, enter the following details on the Classic Clusters page:
1. Cluster Location - Enter the geographical location of the Data Lake.
2. Data Center - Ensure that the data center name is the name that you provided for the Cloudera Base on premises cluster during registration.
3. Tags - Optionally, enter the tags for the cluster.
4. Description - Optionally, enter a description.
Click Add.

You can use the registered Classic Cluster in your hybrid environment.
