第一步：

将hive-0.7.0\lib\py 中所有py文件拷贝到你自己的Python工程中。

第二步：

把下面的代码拷贝一份新建一个py文件，修改IP,port ,输入要执行的SQL。

#encoding=utf-8
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('119.188.7.xx', 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.fetchOne()
        print "............"
    except Thrift.TException, tx:
        print '%s' % (tx.message)
    finally:
        transport.close()

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

#encoding=utf-8
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('119.188.7.xx', 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.fetchOne()
        print "............"
    except Thrift.TException, tx:
        print '%s' % (tx.message)
    finally:
        transport.close()

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

 第三步：

hive --service hiveserver （启动hive server）
