Adding a CLDB Role

About this task

Complete the following steps to add the CLDB role to a node in the cluster:

Install the CLDB package.
Run configure.sh -C on the node where you added the new CLDB role. Using the -C option provides the list of CLDB nodes. If Warden is running, the CLDB service starts automatically.
Run configure.sh on all other nodes in the cluster. Use the -C option and provide the list of CLDB nodes that includes the new node.
Start or restart Warden on the node where you added the CLDB role.
Perform a rolling restart of Warden on all other nodes. Warden picks up the new CLDB node. Issue the following command to restart Warden on the node where you installed the role: % service mapr-warden restart
