Hi ,

I am using 7.3.2 version of Elasticsearch ,here I am using HighLevel Rest Client , here how can I set the clustername for which I have changed the default "Elasticsearch" .

1.Do I need to change the cluster Name from my application level ..if yes How can I change  
2.If not required does my request to Elasticsearch reach .  
(since I am facing connection closed )

Can you please edit your post and remove the formatting you have applied, it makes it very difficult to read and provide assistance 🙂

I don't know. You need to provide more details, like the full stacktrace with the exception, the Java code you are using...  
where is your cluster running?

This is a stack trace. Not the source code you are running which produces this stack trace.

Hi @dadoonet ,

and my clustername is "alliswell"

```auto
private Integer totalSearchHits(BoolQueryBuilder boolQuery, String sortByField, String indexName) 
throws IOException { 
SearchRequest searchR = new SearchRequest(indexName); 
SearchSourceBuilder searchBuilder = new SearchSourceBuilder(); 
 
searchBuilder.query(boolQuery); 
searchBuilder.size(ElasticSearchConstants.ES_MAX_SIZE); 
logger.info("Final query while searching: boolQuery {}", boolQuery); 
searchR.source(searchBuilder); 
// AnalyzeRequest 
SearchResponse searchResponse = client.search(searchR, RequestOptions.DEFAULT); 
return searchResponse.getHits().getHits().length; 
}

```

My Configuration

```auto

@Bean(destroyMethod = "close") 
public RestHighLevelClient client() { 
 
RestClientBuilder builder = RestClient.builder(new HttpHost(host, port)); 
if(StringUtils.isNotEmpty(dbpassword) && (StringUtils.isNotEmpty(dbuserName) 
&& !dbpassword.equalsIgnoreCase("null") && !dbuserName.equalsIgnoreCase("null"))){ 
CredentialsProvider credentialsProvider = new BasicCredentialsProvider(); 
 
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(dbuserName, dbpassword)); 
builder.setHttpClientConfigCallback(httpClientBuilder -> httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider)); 
} 
builder.setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(40000).setSocketTimeout(50000)).setMaxRetryTimeoutMillis(60001); 
 
return new RestHighLevelClient(builder);
