Kibana error on startup (incompatible nodes)

Question

I started using elastic search 7.3.2 and kibana 6.8.3 on mac os mojave 10.14.5.

When kibana starts I got following errors: log [15:21:03.052] [error][status][plugin:[email protected]] Status changed from yellow to red - This version of Kibana requires Elasticsearch v7.3.2 on all nodes. I found the following incompatible nodes in your cluster: v6.2.4 @ 127.0.0.1:9200 (127.0.0.1) log [15:21:03.052] [error][status][plugin:[email protected]] Status changed from yellow to red - This version of Kibana requires Elasticsearch v7.3.2 on all nodes. I found the following incompatible nodes in your cluster: v6.2.4 @ 127.0.0.1:9200 (127.0.0.1)

in the past (several years ago) I used version 6.2.4. How can I get those nodes removed ? I do not need them anymore, how can I remove them in order to let kibana starts correctly ?

Thanks for any help if any

Answer 1

use kibana 6.2.4. or upgrade the elasticsearch to 7.3.2. the elasticsearch and kibana should be the same version.

Answer 2

thanks for help, I solved by deleting the data folder linked from elasticsearch.yml configuration file.

Check your Elasticsearch cluster settings elasticsearch.yml, for each host in your cluster:

cluster.name:

node.name:

discovery.seed_hosts:

cluster.initial_master_nodes:

If your old host is still part of your cluster or discovery, it will continue to throw these errors.
