Clusters cannot be merged if they are made of multiple nodes. However, you can add a single node to an existing cluster. You will need to provide several parameters to add a node to a cluster:
shell> curl -u admin:password -d clusterMemberHostIp=192.168.0.1 \ -d clusterMemberPort=8091 \ -d user=admin -d password=admin123 http://localhost:8091/node/controller/doJoinCluster
The following arguments are required:
