I believe that you are speaking of the Java TransportClient. You don't need to add a license in the client. But don't use the TransportClient as [it is deprecated](https://www.elastic.co/guide/en/elasticsearch/client/java-api/7.6/transport-client.html) and will be removed in the next major version. Use the [REST Client](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.6/index.html) instead. ---
