添加集群：“创建集群错误:调用/群集-信任超时。”
(在datastax论坛上继续讨论同一标题)。我能够重现这样的问题: opscenter无法连接到2.0.1集群，使用“使用现有集群”，失败的消息是“创建集群错误:调用/群集-信任超时”。它与在rpc_server_type中使用“cassandra.yaml : hsha”有关。
我将其转载如下：
(1)在qemu中安装了ubuntu12.04 (x86-64体系结构)。将其更新为所有软件包的最新版本。使用静态ip地址(192.168.77.3)配置它。建立Qemu网络，使主机与qemu虚拟机进行通信。
(2)下载Sun 7u45-Linux-x64.tar.gz并安装它。安装了libjna-java。所有这些都是按照Debian/ubuntu文档上的datastax安装完成的。
(3)使用Debian包安装datastax cassandra 2.0.1，如datastax文档中所述。
(4)对cassandra.yaml作了以下修改：
- 种子：" 192.168.77.3“listen_address: 192.168.77.3 rpc_address: 192.168.77.3 rpc_server_type: hsha :要看到失败，必须使用hsha。
(5)停止cassandra实例(Debian在安装时自动启动它)。注意，init脚本无法阻止cassandra (这是Cassandra2.0中的一个新问题)，所以我不得不手动终止这个过程。这是一个陷阱:您可能认为您重新启动了cassandra，并且它已经考虑到您的配置更改，只是它没有，因为您仍然在运行旧的实例。
(6)清除实例数据: sudo rm -fr /var/lib/cassandra/*
(7)启动了一个新的cassandra实例。检查节点工具可以从虚拟机(即本地运行)和主机连接到它。
(8)尝试在主机上免费运行操作系统(即不在虚拟机上运行)添加集群。操作系统版本3.2.2，ubuntu 13.10。由于还没有添加集群，所以我得到了“欢迎来到”对话框，其中有“CreateNew群集”或“Use现有集群”。选择“使用现有群集”。添加qemu虚拟机实例的ip地址(192.168.77.3)。单击“保存群集”。这与“创建群集错误:调用/群集-信任超时”失败。

不幸的是，这是卡桑德拉的一个错误造成的：
https://issues.apache.org/jira/browse/CASSANDRA-6373
目前的解决办法是使用同步节约服务器。如果在OpsCenter中实现了解决方案，我将更新响应。
