If you leave `cluster.initial_master_nodes` in place once the cluster has
|
|
|
formed then there is a risk that a future misconfiguration may result in
|
|
|
bootstrapping a new cluster alongside your existing cluster. It may not be
|
|
|
possible to recover from this situation without losing data.

The simplest way to create a new cluster is for you to select one of your
|
|
|
master-eligible nodes that will bootstrap itself into a single-node cluster,
