A node can only join a cluster when it shares its `cluster.name` with all the
|
||
|
|
other nodes in the cluster. The default name is `elasticsearch`, but you should
|
||
|
|
change it to an appropriate name which describes the purpose of the cluster.

Make sure that you don't reuse the same cluster names in different environments,
|
||
|
|
otherwise you might end up with nodes joining the wrong cluster.
