Hi! I have a elasticsearch cluster deployed with ECK. The pods are logging:
level": "WARN", "component": "o.e.x.s.a.AuthenticationService", "cluster.name": "elasticsearch", "node.name": "elasticsearch-es-data-6ff4cgt49v", "message": "Authentication to realm default_file failed - Password authentication failed for elastic", "cluster.uuid": "ixv-beimTw-glVn8x3-TEA", "node.id": "guIZqSwRSUm7zU1ZHCu8iw" }
I don't understand de error. Cluster is working (3 master, 3 ingest, 3 data).
Also i have other question. it's possible preserve data volumes from data nodes? I had troubles and I had lost all data. Luckily i had a snapshot of the most important index.
