原因：

That's a security feature of Lettuce to prevent redirects to nodes that are not (yet) known through CLUSTER NODES. The state can arise if the topology changes while your client has a different view. Lettuce loads the topology upon startup/the first cluster connection. Periodic/adaptive refresh can help or you disable validateClusterNodeMembership in ClusterClientOptions.See also https://github.com/lettuce-io/lettuce-core/wiki/Client-Options.
