Hi, I am a new comer.  
I read the official document of Elasticsearch Reference [6.5], which writes "Currently, all secure settings are node-specific settings that must have the same value on every node". Although I am not a native English speaker, per my understanding, node-specific means every node has its own (whether distinct or not), then how can "have the same value on every node" happens?

Hi,

I'm not a native speaker either, but my understanding is that this means: The setting must appear in the config file of every node. You must take care that the setting has the same value on every node.

For example, the xpack.security.transport.ssl.enabled setting has to be present on all ES nodes in /etc/elasticsearch/elasticsearch.yml (if it differs from the default) and the value has to be the same on all nodes (true or false).
