Hbase thrift2 python客户端API无效

我正在编写一个python脚本来从hbase加载数据。但是

节俭

生成的文件似乎出了问题。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_hbase.py”，第46行， 在里面 从\u hbase（thrift\u协议，thrift\u客户端）文件“/load\u hbase.py”，第37行，从\u hbase获取\u行 scan_id=thrift_client.openScanner（hbase_table_name，tscan）文件“/home/lishaohua/kpn/load_hbase/thrift2/hbase/THBaseService.py”， 第715行，在openScanner中 返回self.recv_openScanner（）文件“/home/lishaohua/kpn/load_hbase/thrift2/hbase/THBaseService.py”，第行 735，在recv_openScanner中 result.read（iprot）文件“/home/lishaohua/kpn/load_hbase/thrift2/hbase/THBaseService.py”，第行 3278，已读 fastbinary.decode_binary（self，iprot.trans，（self.类，self.thrift_spec））AttributeError:'TFramedTransport'对象没有 属性“trans”

我在

tttransport.py

中检查代码，

TFramedTransport

具有属性

self.\uu trans

。如何解决这个问题？我可以简单地将

tans

更改为

\u trans

，但是还有更多的问题。

我使用了

TBufferedTransport

而不是

TFramedTransport

，并且它起了作用。您可以在下面尝试我的解决方案：

class ThriftConn(object):
    def __init__(self, ip, port, service_cls):
        self.socket = TSocket.TSocket(ip, port)
        self.trans = TTransport.TBufferedTransport(self.socket)                                                                                                                                                   
        self.protocol = TBinaryProtocol.TBinaryProtocol(self.trans)
        self.client = service_cls.Client(self.protocol)

    def __enter__(self):
        self.trans.open()

    def __exit__(self, exception_type, exception_value, 
        exception_traceback):
        self.trans.close()

HBASE_SERVER_CLIENT = ThriftConn(ip, port, THBaseService)
with HBASE_SERVER_CLIENT:
    scan = TScan()
    scan_id = HBASE_SERVER_CLIENT.client.openScanner(table, scan)
