EC2请求限制超出问题

标签： amazon-ec2 jclouds

我正在运行每日自动化测试（使用JClouds）许多AWS EC2计算机。 问题是，由于“超出请求限制”错误，有时机器无法启动。

从下面的堆栈跟踪中我认为我的操作失败了5次，5次是失败限制。也许这个动作是jclouds的方法describeInstancesInRegion？为什么会失败？

我知道有一个jclouds错误，有时会启动一个空/空名称的机器。跟随describeInstancesInRegion调用会破坏吗？

jclouds version is: 1.6.2-incubating

答案 0 :(得分：3)

你需要告诉jclouds在轮询实例状态更新时不经常发出请求。您可以使用以下替换来执行此操作。

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。虽然它是Rackspace Cloud的一个例子，但代码几乎相同。
