I started using the Shield plugin for security, but then moved to a NGINX reverse proxy. I now have both Shield and NGINX running, but my Shield license expired.
How do I turn off Shield without interrupting the cluster (2 nodes)?
I tried uninstalling the Shield plugin, and that did not do anything. It just removed the admin tools, but the underlying authentication continued to function.
I have the following Shield config files, but I'm afraid that just deleting them may hurt the cluster:
$ ls /etc/elasticsearch/shield/
logging.yml roles.yml users.new
logging.yml.new roles.yml.new users_roles
role_mapping.yml system_key users_roles.new
role_mapping.yml.new users
