我只是设置了一个 EC2 集群并使用 AMI 设置了一个新实例：datastax_clustering_ami_2.5.1_hvm.manifest.xml (ami-7f33cd08) 在 m3.large 实例类型上。仔细按照说明进行操作，发现在过去的几周内有更多人报告了相同的错误。

启动时，它显示以下错误，并且在 OpsCenter 中，没有连接任何节点。这可能是因为以下错误导致设置未成功完成：

从理论上讲，您可以简单地卸载 datastax-agents，然后在每个节点上从头开始重新安装它们。自集群 AMI 很棒，但很多时候我都遇到了问题。另外，当您手动重新安装它们时，您可能会收到更详细的错误消息（如果您遇到任何错误消息）。

您看到的错误可以被忽略并且不应该影响任何功能（如果不是这种情况，请告诉我）。这是一个已知问题，可称为 OPSC-4825
