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）
