Question

我遇到了nodejs的cassandra驱动程序问题 - helenus。我创建了将记录插入表中的函数循环，我用ab工具调用。问题是10-20插入后驱动程序抛出错误：

这是咖啡代码：

helenus = require 'helenus'

pool = new helenus.ConnectionPool(
  hosts: ["mybalancer:9160"]
  keyspace: "stats"
  timeout: 90000
)

pool.on "error", (err) ->
    console.error err.name, err.message

pool.connect (err, keyspace) ->
    if err
      throw (err)
    else
      vals = [uuid.v4(), uuid.v4()]
      #insert_statement = "INSERT INTO test2 (id, name) values(%s, %s)"
      console.log(vals)
      pool.cql insert_statement, vals, (err, results) ->
        console.log err, results

这是错误：

/home/udev/development/project/U/hubber/app/controllers/event_logger_cassandra.js:98
        throw err;
              ^

    at process._tickCallback (node.js:415:13)

我在负载均衡器后面有三个节点（亚马逊上的大型服务器）的cassandra集群。我在服务器上有监视器，节点总是运行正常。

我在这里缺少什么？

感谢。
