Issue upgrade from 6.7 to 7 for single node

Elastic Stack Elasticsearch
1

Hi

I am trying to upgrade from 6.7 to 7 for elasticsearch. I am running my elastic search on single server with one node cluster. I see several warnings. How can I fix this.

Here is my configuration.

network.host: 0.0.0.0
# --------------------------------- Discovery ----------------------------------
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
discovery.seed_hosts: ["prod.server.com"]
# Bootstrap the cluster using an initial set of master-eligible nodes:
cluster.initial_master_nodes: node-1

Error log

@dadoonet sorry< i just removed it for security reasons. Its the same thing you are seeing now in config file.

What is this?

cluster.initial_master_nodes: node-1
5

When I upgraded my Elastic search Inititally I got error starting ES. Added the from this reply.

Sure but node-1 does not exist in your configuration. It's not your node name. It should be I guess prod.server.com?

@dadoonet

I made that change and the elastic search starts good but I see this in logs. Is it because I'm still using kibana 6.7?

You must use the same version.
