    System.out.println(restHighLevelClient.info().getClusterName());

    CreateIndexRequest indexRequest = new CreateIndexRequest("sample-index");
    restHighLevelClient.indices().create(indexRequest);  // exception

hi @blackOcean , we reserve github for confirmed bugs or feature requests. This doesn't seem like a bug to me, you most likely have an old version of the elasticsearch dependency in your classpath. Let's continue this discussion in our forums at https://discuss.elastic.co/. Thanks!

Hi @javanna

Sorry. But elasticsearch dependency are latest. I already mentioned that I am using 6.2.4.
I found the problem : elasticsearch rest high level client is not able to download elasticsearch dependeny as transitive dependency. We have to explicitly pass elasticsearch dependency in mvn pom.xml to make it work.

Solution : Add elasticsearch in pom.xml

 <dependency>
            <groupId>org.elasticsearch</groupId>
            <artifactId>elasticsearch</artifactId>
            <version>6.2.4</version>
        </dependency>

If anybody else encounters this problem with Gradle instead of Maven, you have to state the explicit elasticsearch version like this:

ext['elasticsearch.version'] = '6.3.0'

and remove spring-data-elasticsearch from your project or dependencies because it needs a lower version
