Do we use the new `elasticsearch-java` client mentioned below in es-hadoop and es-spark ?

No, es-hadoop does not use the java client. It has its own [REST client implementation](https://github.com/elastic/elasticsearch-hadoop/blob/main/mr/src/main/java/org/elasticsearch/hadoop/rest/RestClient.java). The main reason is that it predates the java client and there has not been an effort to update it yet.
