We are converting our cluster from data+master nodes to separate master, data, client nodes. I have left the ansible playbooks to install all the plugins on all the nodes. But does this make sense? I started by creating the master-only nodes first, but I get all kinds of errors from marvel because its indices do not exist. (Expected, since the master can't have data.)
So maybe I should be asking for general guidance on how to standup this kind of cluster.
- What order should the nodes be created?
- What plugins should be installed on which node kinds?
