spark运行错误

借贵地问一个问题：我参考spark官网实例 运行spark streaming实例


$ ./bin/run-example streaming.NetworkWordCount localhost 9999...-------------------------------------------Time: 1357008430000 ms-------------------------------------------
(hello,1)(world,1)...

$ nc -lk 9999
hello world

后台一直这样没有出现预想的结果，请问是什么原因呢？
