ConnectionClosedException while using Elastic RestHighLevelClient bulk request

Question

I am using the following code for RestHighLevelClient in Elastic Search.

val credentialsProvider = new BasicCredentialsProvider
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(conf.value.getString("elkUserName"), conf.value.getString("elkPassword")))
val builder = RestClient.builder(new HttpHost(conf.value.getString("elkIp"), Integer.valueOf(conf.value.getString("elkPort"))))
    .setRequestConfigCallback(new RestClientBuilder.RequestConfigCallback() {
        //set timeout
        override def customizeRequestConfig(requestConfigBuilder: RequestConfig.Builder): RequestConfig.Builder = requestConfigBuilder.setConnectTimeout(Integer.valueOf(conf.value.getString("elkWriteTimeOut"))).setSocketTimeout(Integer.valueOf(conf.value.getString("elkWriteTimeOut")))
    }).setHttpClientConfigCallback(new HttpClientConfigCallback() {
        override def customizeHttpClient(httpClientBuilder: HttpAsyncClientBuilder): HttpAsyncClientBuilder = {
            httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider)
        }
    })
client = new RestHighLevelClient(builder)
val requestBuilder = RequestOptions.DEFAULT.toBuilder
requestBuilder.setHttpAsyncResponseConsumerFactory(
    new HttpAsyncResponseConsumerFactory.HeapBufferedResponseConsumerFactory(1024 * 1024 * 1024))


var request = new BulkRequest()
request.setRefreshPolicy("wait_for")
var sizeOfRequest = 1 L
newListOfMap.foreach {
    vals =>
        val newMap = vals.asJava
    request.add(new IndexRequest(indexName).source(newMap))

}
client.bulk(request, requestBuilder.build)

But I am getting the following Exception

java.lang.NoSuchMethodError:

NOTE: The above code is working for smaller size of request but getting above error while posting bigger size of request. Please suggest.

If your project is using both httpcore and httpcore-nio dependencies, ensure that both of their versions are either simultaneously <= 4.4.10 or > 4.4.10.

The suggestion by Harshit is partially what caused this issue in my case. On closer inspection of the logs, it is evident that HttpAsyncRequestExecutor is calling a default constructor called ConnectionClosedException, however, this default constructor does not exist in the destination

The HttpAsyncRequestExecutor is a class of httpcore-nio package. ConnectionClosedException is a class of the httpcore package. This issue starts occurring after v4.4.10, beyond which point the ConnectionClosedException class has a default constructor included which HttpAsyncRequestExecutor calls. For versions <= 4.4.10, the default constructor is not present, however, it is called with a parameter in HttpAsyncRequestExecutor. Thus the versions for both libraries should be either above or below v4.4.10 when being used together.
