Deprecation warning after set search.max_buckets on Elastic 7

Hi all,
On elastic 7, we set the search.max_buckets and after this change, we started to receive this deprecation warning:

#! Deprecation: [discovery.zen.minimum_master_nodes] setting was deprecated in Elasticsearch and will be removed in a future release! See the breaking changes documentation for the next major version

What is the relationship between these two things?

There is no relationship between those 2 things.

Thank u @dadoonet for your answer.
So why of that warning? We are using the elastic cloud solution.

Thanks in advance.

Cloud manages the discovery.zen.minimum_master_nodes setting for you, but this setting is deprecated in 7.0. However, the Cloud infrastructure still sets it on all clusters. At some point during the 7.x series the infrastructure will be updated not to do so, in preparation for upgrades to 8.0, but until then you can ignore this warning.
