我正在运行每天的自动化测试，这些测试从(使用 JClouds)许多 AWS EC2 机器开始。
问题是有时由于“超出请求限制”错误，机器无法启动。
从下面的堆栈跟踪中，我认为我有一个操作失败了 5 次，而 5 是失败限制。也许这个 Action 是jclouds的方法describeInstancesInRegion？为什么失败了？
我知道有一个 jclouds 错误，有时会以空/空名称启动机器。会不会在 describeInstancesInRegion 调用之后破坏？

jclouds version is: 1.6.2-incubating
最佳答案
您需要告诉 jclouds 在轮询实例状态更新时不要经常发出请求。您可以使用以下覆盖来做到这一点。
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();
有关完整示例，请查看 CloudServersPublish .尽管它是 Rackspace Cloud 的示例，但代码几乎相同。
