Configuring a cluster

Manage cassandra.yaml for an entire cluster from OpsCenter.

Manage cassandra.yaml for an entire cluster from OpsCenter. If a cluster exists in multiple data centers, you can configure cassandra.yaml for a single datacenter or for all nodes in a cluster.
Note: When configuring a cluster using a datacenter-aware snitch (EC2, EC2MR, GPFS, PFS, GCE), the topology of nodes cannot be configured through OpsCenter. Forthcoming versions of OpsCenter will provide more robust support for additional snitches. All snitches available in Cassandra are described in the Cassandra documentation.

Follow the steps below to configure cassandra.yaml for all nodes in a cluster.

Procedure

  1. Click Nodes in the left navigation pane.
  2. Click Cluster Actions > Configure.
    The Edit Cluster Config - All Nodes dialog appears.
  3. Edit the values for any of the options. Click the scroll bars to access all of the available options.
    For option descriptions, see the documentation for the Cassandra version that the cluster or node is running, such as cassandra.yaml.
  4. When you are done, click Save Configuration.
    You are prompted to proceed with a rolling restart of the cluster.
