What sort of logs should I see when ignite nodes discovery each other?
There is a message that you can see in the logs on each topology change event:
Topology snapshot [ver=2, locNode=abffa279, servers=2, clients=0, state=ACTIVE, CPUs=32, offheap=32.0GB, heap=16.0GB]
It means that nodes were able to find each other and joined the cluster.
