我正在编写一个python脚本来从hbase加载数据。但事情似乎出了问题 thrift 生成的文件。这是我的密码：

def create_hbase_connection():
    thrift_socket = TSocket.TSocket(thrift_server, thrift_port)
    thrift_socket.setTimeout(thrift_timeout)
    thrift_transport = TTransport.TFramedTransport(thrift_socket)
    thrift_protocol = TBinaryProtocol.TBinaryProtocolAccelerated(thrift_transport)
    thrift_client = THBaseService.Client(thrift_protocol)
    try:
        thrift_transport.open()
    except Exception as e:
        print "connect to hbase thrift failed. (%s)" % e
        sys.exit()

    return thrift_protocol, thrift_client

def fetch_rows_from_hbase(thrift_protocol, thrift_client, start_row = None):
    tscan = ttypes.TScan()
    if start_row != None:
        tscan.startRow = start_row
    tscan.maxVersions = max_versions
    tscan.filterString = "FamilyFilter(!=, 'binary:ge')"
    scan_id = thrift_client.openScanner(hbase_table_name, tscan)
    result = thrift_client.getScannerRows(scan_id, row_limits + 1)
    print result
    print "=================================================\n"
    thrift_client.closeScanner(scan_id)
    thrift_protocol.close()

if __name__ == '__main__':
    thrift_protocol, thrift_client = create_hbase_connection()
    fetch_rows_from_hbase(thrift_protocol, thrift_client)

下面是错误：
回溯（最后一次调用）：文件“/load\u hbase.py”，第46行，在fetch\u rows\u from\u hbase（thrift\u protocol，thrift\u client）文件“/load\u hbase.py”，第37行，在fetch\u rows\u from\u hbase scan\u id=thrift\u client.openscanner（hbase\u table\u name，tscan）文件“/home/lishaohua/kpn/load\u hbase/thrift2/hbase/thbaseservice.py”，第715行，在openscanner return self.recv\u openscanner（）file“/home/lishaohua/kpn/load\u hbase/thrift2/hbase/thbaseservice.py”行735中，在recv\u openscanner result.read（iprot）file“/home/lishaohua/kpn/load\u hbase/thrift2/hbase/thbaseservice.py”行3278中，读取fastbinary.decode\u binary（self，iprot.trans，（self.class，self.thrift\u spec）attributeerror:“tframedtransport”对象没有属性“trans”
我把密码签入 TTransport.py , TFramedTransport 具有属性 self.__trans . 如何解决这个问题？我可以改变 tans 至 __trans ，但问题更多。
