Node.name unique?

Wondering if node.name must be unique or not? We setup a new cluster with Docker, and we have the same node name everywhere, it seems working fine.

node.name does not necessarily to be unique. On startup each node generates an ID that needs to be unique (thos cloning is potentially a problem).

thanks you, so not a big deal to name all data nodes "data".
