I am trying to create index onto Elasticsearch 7.1 using below code snippet.

private void createIndex(String indexName, String jsonFile) throws URISyntaxException, IOException {  
String jsonData = getJsonString(jsonFile);

```
        CreateIndexRequest request = new CreateIndexRequest(indexName);
        request.settings(Settings.builder()
                .put("index.number_of_shards", 10)
                .put("index.number_of_replicas", 1)
        );
        request.source(jsonData, XContentType.JSON);
        CreateIndexResponse response = transportClient.admin().indices().create(request).actionGet();

        if (response.isAcknowledged()) {
            out.println("Index created successfully");
        } else {
            out.println("Failed to create index");
        }
    }

    protected String getJsonString(String jsonFile) throws IOException, URISyntaxException {
        return new String(Files.readAllBytes(
                Paths.get(Objects.requireNonNull(App.class.getClassLoader().getResource(jsonFile)).toURI())));
    }

    private void initializeClient() {
        System.setProperty(ES_SET_NETTY_RUNTIME_AVAILABLE_PROCESSORS, "false");
        Settings.Builder settings = Settings.builder()
                .put(CLUSTER_NAME, "cluster")
                .put(CLIENT_TRANSPORT_SNIFF, false);
        transportClient = new PreBuiltTransportClient(settings.build());
             String host = "hostname";
            int port = 32545;
            out.println("Adding Indexer - [Host: " + host + "] and [Port:" + port + "]");
            transportClient.addTransportAddress(new TransportAddress(new InetSocketAddress(host.trim(), port)));
            out.println("Successfully created transport client.");
    }

```

-------Json file content------------------

{  
"settings": {  
"number\_of\_shards": 1  
},  
"mappings": {  
"properties": {  
"field1": {  
"type": "text"  
}  
}  
}  
}

Which is giving me below exception -

Elasticsearch index creation failed for Impact management service.

@anagha Have you tried using Java High Level Rest Client?  
[https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.3/java-rest-high.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.3/java-rest-high.html)

TransportClient is going away in the future releases.
