Hi,

I'm creating a plugin that blacklists certain API calls. Right now I've created a .yml file in the src/main/resources directory of my project, where I read the blacklisted APIs from.  
The problem is, if I want to add more blacklisted API's to the list, I have to remove the plugin, change the yml file, rebuild and reinstall the plugin. I'd like my plugin to be able to read directly from elasticsearch.yml, so that I don't have to do this. Is this possible?  
Any suggestions would be greatly appreciated.

Thanks

It's possible. You need to declare some settings for that.

Here is an example of settings:

> <https://github.com/elastic/elasticsearch/blob/master/plugins/discovery-ec2/src/main/java/org/elasticsearch/discovery/ec2/Ec2ClientSettings.java>

And how you declare them in the plugin:

> <https://github.com/elastic/elasticsearch/blob/5b454000755dc4c8c1c8cdce78656facf751d6d0/plugins/discovery-ec2/src/main/java/org/elasticsearch/discovery/ec2/Ec2DiscoveryPlugin.java#L104-L126>
