EC2 요청 제한이 나는 많은 AWS EC2 기계 (JClouds으로) 시작 매일 자동화 된 테스트를 실행하고있어 문제

Question

를 초과했습니다. 문제는 가끔 기계가 오류를 "초과 요청 제한"으로 인해 시작에 실패합니다. 내가 5 번 실패하는 작업을 생각 아래 스택 추적에서

, 5는 실패가 제한됩니다. 아마도이 작업은 jclouds의 메서드 인 describeInstancesInRegion입니까? 왜 실패 했나요?

은 가끔 빈/널 이름을 가진 기계를 시작하는 jclouds 버그가 알고있다. describeInstancesInRegion 호출 다음에 망가질 수 있습니까?

스택 추적 : 당신은이 인스턴스 상태 업데이트에 대한 폴링이 때 너무 자주 요청을하지 jclouds 말할 필요

jclouds version is: 1.6.2-incubating 

Answer 1

. 당신은 다음과 같은 재정의 할 수 있습니다.

Properties overrides = new Properties(); 
overrides.setProperty(POLL_INITIAL_PERIOD, POLL_PERIOD_TWENTY_SECONDS); 
overrides.setProperty(POLL_MAX_PERIOD, POLL_PERIOD_TWENTY_SECONDS); 

ComputeServiceContext context = ContextBuilder.newBuilder(PROVIDER) 
     .credentials(username, apiKey) 
     .overrides(overrides) 
     .buildView(ComputeServiceContext.class); 
computeService = context.getComputeService(); 

전체 예제는 CloudServersPublish입니다. Rackspace Cloud의 사례이지만 코드는 거의 동일합니다. 재생을위한
