thrift 是facebook开发并开源的一个二进制通讯中间件，通过thrift，我们可以充分利用各个语言的优势，编写高效的代码。

关于thrift的论文：http://pan.baidu.com/share/link?shareid=234128&uk=3238841275

安装thrift：http://thrift.apache.org/docs/install/ubuntu/

安装完成后到hbase的目录下，找到Hbase.thrift，该文件在

hbase-0.94.4/src/main/resources/org/apache/hadoop/hbase/thrift下可以找到

thrift --gen py hbase.thrift 会生成gen-py文件夹，将其修改成hbase

安装python的thrift库

sudo pip install thrift

启动hbase的thrift服务：bin/hbase-daemon.sh start thrift 默认端口是9090

创建hbase表:

1 from thrift import Thrift 2 from thrift.transport import TSocket 3 from thrift.transport import TTransport 4 from thrift.protocol import TBinaryProtocol 5  6 from hbase import Hbase 7 from hbase.ttypes import * 8  9 transport = TSocket.TSocket('localhost', 9090);10 11 transport = TTransport.TBufferedTransport(transport)12 13 protocol = TBinaryProtocol.TBinaryProtocol(transport);14 15 client = Hbase.Client(protocol)16 transport.open()17 18 19 contents = ColumnDescriptor(name='cf:', maxVersions=1)20 client.createTable('test', [contents])21 22 print client.getTableNames()

执行代码，成功后，进入hbase的shell，用命令list可以看到刚刚的test表已经创建成功。

插入数据：

1 from thrift import Thrift 2 from thrift.transport import TSocket 3 from thrift.transport import TTransport 4 from thrift.protocol import TBinaryProtocol 5  6 from hbase import Hbase 7  8 from hbase.ttypes import * 9 10 transport = TSocket.TSocket('localhost', 9090)11 12 transport = TTransport.TBufferedTransport(transport)13 14 protocol = TBinaryProtocol.TBinaryProtocol(transport)15 16 client = Hbase.Client(protocol)17 18 transport.open()19 20 row = 'row-key1'21 22 mutations = [Mutation(column="cf:a", value="1")]23 client.mutateRow('test', row, mutations, None)

插入成功，通过scan命令查看插入结果：

获取一行数据：

 

1 from thrift import Thrift 2 from thrift.transport import TSocket 3 from thrift.transport import TTransport 4 from thrift.protocol import TBinaryProtocol 5  6 from hbase import Hbase 7 from hbase.ttypes import * 8  9 transport = TSocket.TSocket('localhost', 9090)10 transport = TTransport.TBufferedTransport(transport)11 12 protocol = TBinaryProtocol.TBinaryProtocol(transport)13 14 client = Hbase.Client(protocol)15 16 transport.open()17 18 tableName = 'test'19 rowKey = 'row-key1'20 21 result = client.getRow(tableName, rowKey, None)22 print result23 for r in result:24     print 'the row is ' , r.row25     print 'the values is ' , r.columns.get('cf:a').value

 

getRow返回的是TResult列表，结果如下：

返回多行则需要使用scan：

1 from thrift import Thrift 2 from thrift.transport import TSocket 3 from thrift.transport import TTransport 4 from thrift.protocol import TBinaryProtocol 5  6 from hbase import Hbase 7 from hbase.ttypes import * 8  9 transport = TSocket.TSocket('localhost', 9090)10 transport = TTransport.TBufferedTransport(transport)11 12 protocol = TBinaryProtocol.TBinaryProtocol(transport)13 14 client = Hbase.Client(protocol)15 transport.open()16 17 scan = TScan()18 tableName = 'test'19 id = client.scannerOpenWithScan(tableName, scan, None)20 21 result2 = client.scannerGetList(id, 10)22 23 print result2

scannerGetList会取10条数据，然后输出结果

 scannerGet则是每次只取一行数据：

1 from thrift import Thrift 2 from thrift.transport import TSocket 3 from thrift.transport import TTransport 4 from thrift.protocol import TBinaryProtocol 5  6 from hbase import Hbase 7 from hbase.ttypes import * 8  9 transport = TSocket.TSocket('localhost', 9090)10 transport = TTransport.TBufferedTransport(transport)11 12 protocol = TBinaryProtocol.TBinaryProtocol(transport)13 14 client = Hbase.Client(protocol)15 transport.open()16 17 scan = TScan()18 tableName = 'test'19 id = client.scannerOpenWithScan(tableName, scan, None)20 result = client.scannerGet(id)21 while result:22     print result23     result = client.scannerGet(id)

输出结果：
