EC2 starcluster已停止工作

Question

EC2 ubuntu上的Starcluster停止工作。我没有意识到任何故意的配置更改或其他任何事情，也找不到太多的帮助。你能告诉我如果有人有什么建议吗？启动、终止甚至列出集群都是错误的。下面是我尝试列出集群时得到的错误：

ubuntu@ip-10-29-249-203:~$ starcluster listclusters
StarCluster - (http://star.mit.edu/cluster) (v. 0.94)

您使用的是哪个版本的StarCluster？是最新的版本还是最新的开发版本？

如果我在最新的dev版本上查看您的错误，它指的是下面这一行：

https://github.com/jtriley/StarCluster/blob/5442e91e159acca48b645f5ddf629d65c59cd7e0/starcluster/node.py#L139

我的猜测是你的集群别名标签有问题。在任何情况下，非常奇怪的是，即使终止集群并开始一个新的集群也不能解决问题。

如果您发现更多，可以重现问题或需要更多帮助，您也可以使用StarCluster邮件列表。http://mailman.mit.edu/mailman/listinfo/starcluster
