creating index using RestHighLevelClient failing

Question

I am trying to create index using RestHighLevelClient, Client got created successfully but while creating index I am getting error.

 CreateIndexRequest request = new CreateIndexRequest(elasticsearchIndex);
    request.settings(Settings.builder()
            .put("index.number_of_shards", 1)
            .put("index.number_of_replicas", 0)
    );
    org.elasticsearch.client.indices.CreateIndexResponse createIndexResponse = elasticsearchClient.indices().create(request, RequestOptions.DEFAULT);





Exception in thread "main" java.net.ConnectException: Connection refused
        at org.elasticsearch.client.RestClient.extractAndWrapCause(RestClient.java:788)
        at org.elasticsearch.client.RestClient.performRequest(RestClient.java:218)
        at org.elasticsearch.client.RestClient.performRequest(RestClient.java:205)
        at org.elasticsearch.client.RestHighLevelClient.internalPerformRequest(RestHighLevelClient.java:1454)

        at org.elasticsearch.client.IndicesClient.create(IndicesClient.java:128)

Please let me know the root cause or any solution.

Thanks

Looks like a connection problem: "Connection refused". I'd check connection parameters. — jerkan, Dec 22 '20 at 09:52

Looks like you Application can't connect to the elasticsearch server, can you check the connection setting provided in JHLRC client configuration(hostname and port) and make sure you have connection to your elasticsearch.

You can check the connection yourself by hitting your elasticsearch hostname and port using rest client like postman etc. Also make sure your Application and elasticsearch server have the network connectivity.
