Our pipeline has been using Apache spark to write into elasticsearch from upstream. The transport client was being used until ES version-2.4 We are now trying to upgrade to ES 5.4 and are using the maven dependency for version 5.4.0 and 5.4.1 (we understand that transport client is now a different artifact) According elastic search client java documentation link: [https://www.elastic.co/guide/en/elasticsearch/client/java-api/5.4/transport-client.html](https://www.elastic.co/guide/en/elasticsearch/client/java-api/5.4/transport-client.html) Class **PreBuiltTransportClient** needs to be implemented to build transport client. Can the code from GitHub here [https://github.com/elastic/elasticsearch/tree/f8a48badcf4293396925308962c7d1bd2a357845](https://github.com/elastic/elasticsearch/tree/f8a48badcf4293396925308962c7d1bd2a357845) be used or do you have an example? ---
