(继续在datastax论坛上使用相同的标题进行讨论)。我能够重现opscenter无法连接到2.0.1群集的问题,使用“使用现有群集”,失败并显示消息“创建群集时出错:调用/ cluster-configs超时”。它与cassandra.yaml中的“rpc_server_type:hsha”有关。
我将其复制如下:
(1)在qemu中安装了ubuntu 12.04(x86-64架构)。将其更新为所有软件包的最新版本。配置静态IP地址(192.168.77.3)。设置了Qemu网络,以便主机和qemu虚拟机可以进行通信。
(2)下载Sun jre-7u45-linux-x64.tar.gz并安装它。安装了libjna-java。这一切都按照在Debian / ubuntu文档上安装的datastax完成。
(3)使用Debian软件包安装datastax cassandra 2.0.1,如数据存档文档中所述。
(4)对cassandra.yaml进行了以下更改:
(5)停止cassandra实例(Debian在安装时自动启动它)。请注意,init脚本不能用于停止cassandra(这是cassandra 2.0的新问题),因此我不得不手动终止该过程。这是一个陷阱:你可能认为你已经重新启动了cassandra并且它已经考虑了你的配置更改,只是因为你还在运行旧实例而没有。
(6)清除实例数据:sudo rm -fr / var / lib / cassandra / *
(7)开始了一个新的cassandra实例。检查nodetool是否可以从虚拟机(即本地运行)和主机连接到它。
(8)尝试在主机上运行无运行的集群(即未在虚拟机上运行)。 opscenter版本3.2.2,ubuntu 13.10。由于尚未添加任何群集,因此我获得了“欢迎使用Datastax opscenter”对话框,其中包含“创建新群集”或“使用现有群集”。选择“使用现有群集”。添加了qemu虚拟机实例的IP地址(192.168.77.3)。单击“保存群集”。这失败了“创建集群时出错:调用/ cluster-configs超时”。

答案 0 :(得分:1)
这是由于Cassandra的一个错误:
https://issues.apache.org/jira/browse/CASSANDRA-6373
目前的解决方法是使用sync thrift服务器。如果在OpsCenter中实施了解决方法,我将更新我的响应。
