Thrift是一个跨语言服务部署框架，最初由Facebook于2007年开发，后于2008年进入Apache孵化器(Apache Incubator)。类似于SOAP，COM 和CORBA，Thrift通过定义一个中间定义语言和Thrift代码生成工具，生成指定语言的代码。

目前，Thrift支持C++,Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, Smalltalk和OCaml的代码生成

1.   安装thrift依赖库

yum install automake libtool flex bison pkgconfig gcc-c++ boost-devel libevent-devel zlib-devel python-devel ruby-devel 

下载thrift:http://mirror.bjtu.edu.cn/apache//thrift/0.8.0/thrift-0.8.0.tar.gz

安装thrift

tar
-zxvf thrift-0.8.0.tar.gz

cd
 thrift-0.8.0

./configure
--with-boost=/usr/local

make &&
make install

我的hive使用的是cloudera cdn3u3版本，python版本为2.7

在使用Python连接hive之前需要将hive中的文件拷贝到python的sys.path中

cp -r $HIVE_PATH/lib/py /usr/local/lib/python2.7/site-packages

 

#!/usr/bin/env python
import sys
from hive_service import ThriftHive
from hive_service.ttypes import HiveServerException
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol

def hiveExe(sql):

    try:
        transport = TSocket.TSocket('127.0.0.1', 10000)
        transport = TTransport.TBufferedTransport(transport)
        protocol = TBinaryProtocol.TBinaryProtocol(transport)
        client = ThriftHive.Client(protocol)
        transport.open()


        client.execute(sql)

        print "The return value is : "
        print client.fetchAll()
        print "............"
        transport.close()
    except Thrift.TException, tx:
        print '%s' % (tx.message)

if __name__ == '__main__':
    hiveExe("select * from t_afan_test")
