我在CentOS 6上安装了3个cassandra节点（S1，S2，S3）。它们中的两个（S1，S2）位于数据中心A中，其中一个（S3）位于openshift中。 我正在尝试使用多个数据中心中的多个节点群集进行基准testing。
Cassandra节点S1和S2上的安装和configuration基于在基于RHEL的系统上安装DataStax社区另一方面，节点S3（openshift）上的cassandra安装基于如何在OpenShift上configuration和运行Cassandra 。
所有的服务器运行良好，但我不能添加节点S3到群集。 所有服务器都有完全相同的configuration文件（cassandra.yaml和cassandra-topology.properties）
节点S1和S2具有cassandra的1.2.18版本。
[root@node1 ~]# cassandra -v 1.2.18 节点S3有cassandra的1.1.6版本。

所有节点具有相同的cassandra.yaml和cassandra-topology.propertiesconfiguration，如下所示（除了监听ip地址）。
cassandra.yaml
cluster_name: 'MyDemoCluster' num_tokens: 256 seed_provider: - class_name: org.apache.cassandra.locator.SimpleSeedProvider parameters: - seeds: "xxx236" listen_address: xxxx endpoint_snitch: PropertyFileSnitch
cassandra-topology.properties
# Cassandra Node IP=Data Center:Rack xxx236=XXX:RAC1 xxx237=XXX:RAC2 yyyyyy=OPS:RAC1
首先，我开始种子节点，而其他节点停止。 成功启动后，我启动了其他节点（日志文件中没有任何错误消息）。
然后，当我在种子节点上运行节点工具，我只看到节点S1和S2，而不是节点S3。
