You can't merge two existing clusters with each other.

You will need to remove all data from all machines in the empty cluster and join them to the existing cluster one by one as you would do normally when scaling up. From what you write it seems you have two seperate clusters with the logical seperator being cluster_name configuration value. You need to makes sure this value is the name of the existing cluster.
