Question

我遇到麻烦连接到cassandra 我试图连接到s-cassandra（这是一个可以查看here的存根cassandra），使用 datastax node.js cassandra驱动程序。

由于某种原因通过＆＃34; 127.0.0.1：8042＆＃34;作为司机的联络点导致 DriverInternalError ：

（很难有时它会随机工作，我还没弄清楚为什么有时会这样做，有时我不会...）

DriverInternalError 我得到：

{＆＃34; name＆＃34;：＆＃34; DriverInternalError＆＃34;，
  ＆＃34; stack＆＃34;：＆＃34; ...＆＃34;，
＆＃34;消息＆＃34;：＆＃34;本地数据中心不可能   确定＆＃34;，
   ＆＃34; info＆＃34;：＆＃34;表示驱动程序内或驱动程序中的错误   卡桑德拉主持人。＆＃34; }

这就是我从Cassandra Driver的日志中看到的：

(map #(:user %) users)

无法使用datastax-driver连接到scassandra（stubbed cassandra）
