I have deployed in Kubernetes a Statefulset that creates 3 nodes of Elasticsearch of the master+data type, sharing the same volume. Then I saw this warning.
Never run different node types (i.e. master, data) from the same data directory. This can lead to unexpected data loss.
Is there a risk if all nodes are of the same type (master and data)? Because the warning can be interpreted that the nodes cannot be of different type, ie there could not be 2 master nodes and 3 data nodes (master or data), but it could be that there is no risk having all nodes equal, master+data.
Thank you very much in advance.
