I have a cluster of 3 nodes. I need to change a setting in elasticsearch.yml and then restart the cluster. I am a bit confused on the procedure. Here is what I have so far. Is this correct?
- Make changes to /etc/elasticsearch/elasticsearch.yml on all 3 nodes in the cluster.
- On the master node only, run sudo service elasticsearch restart
Is this all there is to it? Or do I need to also run commands on the child nodes as well?
