AWS Athena ClientExecutionTimeoutException

Я пытаюсь сделать POC для AWS Athena, используя Java. Я использую пример кода, указанный в https://docs.aws.amazon.com/athena/latest/ug/code-samples.html

BasicAWSCredentials awsCredentials = new BasicAWSCredentials("accesskey","secretkey");

private final AmazonAthenaClientBuilder builder = AmazonAthenaClientBuilder.standard()
      .withRegion(Regions.US_EAST_1)
      .withCredentials(new AWSStaticCredentialsProvider(awsCredentials))
      .withClientConfiguration(new ClientConfiguration().withClientExecutionTimeout(5000));

public AmazonAthena createClient()
{
  return builder.build();
}
=============================================================

public class StartQueryExample
{
 public static void main(String[] args) throws InterruptedException
 {
  AthenaClientFactory factory = new AthenaClientFactory();
  AmazonAthena client = factory.createClient();
  String queryExecutionId = submitAthenaQuery(client);
 }

 private static String submitAthenaQuery(AmazonAthena client)
 {
  QueryExecutionContext queryExecutionContext = new QueryExecutionContext().withDatabase("DB_Name");

  ResultConfiguration resultConfiguration = new ResultConfiguration()
          .withOutputLocation("s3://bucket_name/results");

  StartQueryExecutionRequest startQueryExecutionRequest = new StartQueryExecutionRequest()
          .withQueryString("select * from tablename")
          .withQueryExecutionContext(queryExecutionContext)
          .withResultConfiguration(resultConfiguration);

  StartQueryExecutionResult startQueryExecutionResult = client.startQueryExecution(startQueryExecutionRequest);

  return startQueryExecutionResult.getQueryExecutionId();
 }

Пример таблицы содержит только 6 строк и 2 столбца. Я попытался запустить код с помощью Boto3, и он отлично работает.

Но при запуске из Java я получаю исключение ClientExecutionTimeoutException: 

Exception in thread "main" **com.amazonaws.http.timers.client.ClientExecutionTimeoutException: Client execution did not complete before the specified timeout configuration.**

    at com.capitalone.aws.athena.StartQueryExample.submitAthenaQuery(StartQueryExample.java:60)
    at com.capitalone.aws.athena.StartQueryExample.main(StartQueryExample.java:32)

Я попытался запустить его из eclipse, а также попытался создать jar и запустить его на экземпляре ec2 с использованием роли Athena IAM.

Любая помощь будет полезна.

Спасибо

Исправлена ​​вышеуказанная проблема, исправляя эти строки

.withClientConfiguration(buildClientConfig().withClientExecutionTimeout(5000));

 private ClientConfiguration buildClientConfig() {
  ClientConfiguration clientConfiguration = new ClientConfiguration();
  clientConfiguration.setProxyHost("host");
  clientConfiguration.setProxyPort(port);
  clientConfiguration.setProxyUsername("");
  clientConfiguration.setProxyPassword("");
  clientConfiguration.setPreemptiveBasicProxyAuth(false);
  clientConfiguration.setConnectionTimeout(2000);
  clientConfiguration.setRequestTimeout(2000);
  return clientConfiguration;

}
