I am running a Elasticsearch 7.2 version and I had a property defined in my Elasticsearch.yml file that is - _**discovery.zen.ping.unicast.hosts: [IP1, IP2....]**_  
but obviously when I read the documentation I see that this _ **discovery.zen.ping.unicast.hosts:** _ property is not supported any more starting elasticsearch7.x and have been replaced with _**discovery.seed\_hosts:[IP1, IP2]**_ so I did that change today and restarted the nodes and the cluster came up green in health with no problems however when I hit cluster settings API that is -  
[http://localhost:9200/\_cluster/settings?pretty&include\_defaults](http://localhost:9200/_cluster/settings?pretty&include_defaults)  
I have commented the _ **discovery.zen.ping.unicast.hosts:** _ completely and only has _ **discovery.seed\_hosts** _ in my Elasticsearch.yml  
I still the ZEN property nested inside discovery ( on 4/5th line below response from cluster setting api ) so I wanted to know how can I completly remove zen or what am I doing wrong here, sorry I am new to ES so maybe you guys notice anything or should be able to help me out.

These settings are still there in 7.x for compatibility reasons. To remove them completely, upgrade to 8.x.
