问题
I am currently attempting to create a cluster on MarkLogic and would like to ask if is there a need for a license to create the cluster? I managed to get Machine B to connect to Machine A but it begins a "Restarting MarkLogic Server to load new group configurations" and results in an error "ERROR: too many loops!".
I have tested with pinging and opening of the admin page via port 8001 from one machine to the other.
Both database is empty and do not have any type of license. For now I know that unfiltered geospatial search requires licensing, if anyone can let me know any other limitations due to licensing would be greatly appreciated.

MarkLogic uses a number of ports, not just 8001. Make sure that 7997,7999, 8000, 8001, 8002 are accessible between the machines.
Also, as mentioned in the comments, make sure all hostnames can be resolved (either via DNS or /etc/hosts) on all systems. Even if you add the system via IP, it will attempt to resolve the IP to a hostname, and the cluster creation process will use the hostname to complete the setup.
