Question

我有一个3节点的cassandra 2.1.0集群，我正在尝试使用datastax 2.1.4 java驱动程序通过Java单元测试创建一个密钥空间。但是当我尝试创建一个密钥空间时，我在Cassandra system.log文件中看到以下错误：

ERROR [SharedPool-Worker-1] 2015-01-28 15:08:24,286 ErrorMessage.java:218 - Unexpected exception during request

任何人都知道这里会发生什么？

Answer 1

我遇到了同样的问题。如果将所有节点设置为接触点，问题似乎就会消失。

给出节点A，B，C：
