Adding a Client for Cassandra
After you install the Cassandra Agent, configure a client for the Cassandra database instance, and then configure the Cassandra nodes.
The client is the interface that you use to manage the Cassandra cluster. When you add a client, you specify the instance that represents the Cassandra cluster that you want to protect.
- From the CommCell Bowser, right-click <Client Computers, point to New Client > Distributed Apps, and then click Cassandra.
The Create Cassandra Client dialog box appears.
- On the General tab, enter the Cassandra cluster details.
- In the Client Name box, type the name.
- In the Instance Name box, type the name that represents the Cassandra cluster in the CommCell Console.
- From the Coordinator Node list, select the Cassandra node that the Commvault software connects to, and uses for managing and initiating Cassandra node data protection operations.
- In the CQL Host box, type the IP address of the node the software uses for Cassandra CQL connections.
- In the Cassandra Gateway CQL Port box, type the port that the software uses for Cassandra CQL connections.
The default is 9042.
- By default, the software uses the root user to connect to Cassandra on the CQL host. To use a different user, next to Cassandra Gateway User, click Change, and then enter the user credentials.
- In the Gateway Java path box, type the full path to the Cassandra gateway node Java installation path, for example, /opt/java/jre1.8.0_91/bin.
Note: When you specify the Java path, and the data directory, do not end the path with the "/".
- On the Storage Device tab, on the Data Storage Policy tab, from the Storage Policy used by default subclient list, select the storage policy.
- Click OK.
The software creates the following entities:
- The client
- An instance with the name that you specified
- A default subclient
After you configure your Cassandra nodes, you can perform the backup and restore operations on the default subclient.
