Disabling the Cassandra Service on a Junos Space Node
You can delete Cassandra nodes from a Junos Space fabric by either deleting the Cassandra nodes or by disabling the Apache Cassandra service on JBoss nodes.
For information about deleting Cassandra nodes from a fabric, see Deleting a Node from the Junos Space Fabric.
When a Cassandra node is deleted, the data stored in the Cassandra node is not moved back to the MySQL database.
To stop and disable the Cassandra service on a JBoss node:
- On the Junos Space Platform UI, select Administration
The Fabric page appears.
- Select a Cassandra node that you want to remove from the fabric.
- Click Stop Cassandra to stop the Cassandra
service on the node.
A confirmation dialog box prompts you to confirm that you want to stop the Cassandra service.
Alternatively, you can use the service cassandra stop command on the node CLI to stop the Cassandra service.
- Click Yes to stop the Cassandra service on
The Status dialog box displays the status of the stop the Cassandra service operation.
- After the Cassandra service is stopped, on the Fabric page, select the node on which you want to disable the Cassandra service.
- Select Actions > Disable Cassandra.
A confirmation dialog box prompts you to confirm that you want to disable the Cassandra service.
- Click Yes to disable the Cassandra service
on the Cassandra node.
A job is created to disable the Cassandra service on the JBoss node. Navigate to the Job Management page to view job details.
The Cassandra service is disabled on the node and the node acts only as a JBoss node.
