我让accumulo在虚拟机上运行。这个groovy脚本在vm内部可以很好地连接，但是在vm外部，它在第一个println语句处挂起。

String instance = "test"
String zkServers = "localhost:2181"
String principal = "root";
AuthenticationToken authToken = new PasswordToken("testing1234");

ZooKeeperInstance inst = new ZooKeeperInstance(instance, zkServers);
println "Attempting connection"
Connector conn = inst.getConnector(principal, authToken);
println "Connected!"

以下是我在vagrant开设的港口清单：

你知道为什么不让我联系吗？它只是挂着，似乎从来没有超时。
