thrift tutorial中执行python的PythonServer.py，遇到如下错误：

[zhouhh@Hadoop48 py]$ python PythonServer.py
Starting the server...
Traceback (most recent call last):
  File "PythonServer.py", line 95, in <module>
    server.serve()
  File "build/bdist.linux-x86_64/egg/thrift/server/TServer.py", line 74, in serve
  File "build/bdist.linux-x86_64/egg/thrift/transport/TSocket.py", line 136, in listen
  File "build/bdist.linux-x86_64/egg/thrift/transport/TSocket.py", line 31, in _resolveAddr
TypeError: getaddrinfo() argument 1 must be string or None

我们看一下File “PythonServer.py”, line 95，是这句

transport = TSocket.TServerSocket(9090)

我们看TserverSocket源码，[root@Hadoop48 py]# vim build/lib.linux-x86_64-2.7/thrift/transport/TSocket.py

def __init__(self, host=None, port=9090, unix_socket=None):

这是因为其初始化函数，第一个参数是host，第二个参数是port，所以想省去host，只填port是不行的。

将File “PythonServer.py”, line 95改为：

transport = TSocket.TServerSocket('localhost',9090)

或者改为：

transport = TSocket.TServerSocket(port=9090)

即可解决该问题。
