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 python 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:
# @param python通过thrift操作hbase实例
# @author 编程之家 jb51.cc|jb51.cc
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from hbase import Hbase
from hbase.ttypes import *
transport = TSocket.TSocket('localhost',9090);
transport = TTransport.TBufferedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport);
client = Hbase.Client(protocol)
transport.open()
contents = ColumnDescriptor(name='cf:',maxVersions=1)
client.createTable('test',[contents])
print client.getTableNames()
# End www.jb51.cc
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：
# @param python通过thrift操作hbase实例
# @author 编程之家 jb51.cc|jb51.cc
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from hbase import Hbase
from hbase.ttypes import *
transport = TSocket.TSocket('localhost',9090)
transport = TTransport.TBufferedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = Hbase.Client(protocol)
transport.open()
row = 'row-key1'
mutations = [Mutation(column="cf:a",value="1")]
client.mutateRow('test',row,mutations,None)
# End www.jb51.cc
获取一行数据：
# @param python通过thrift操作hbase实例
# @author 编程之家 jb51.cc|jb51.cc
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from hbase import Hbase
from hbase.ttypes import *
transport = TSocket.TSocket('localhost',9090)
transport = TTransport.TBufferedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = Hbase.Client(protocol)
transport.open()
tableName = 'test'
rowKey = 'row-key1'
result = client.getRow(tableName,rowKey,None)
print result
for r in result:
print 'the row is ',r.row
print 'the values is ',r.columns.get('cf:a').value
# End www.jb51.cc
返回多行则需要使用scan：
# @param python通过thrift操作hbase实例
# @author 编程之家 jb51.cc|jb51.cc
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from hbase import Hbase
from hbase.ttypes import *
transport = TSocket.TSocket('localhost',9090)
transport = TTransport.TBufferedTransport(transport)
protocol = TBinaryProtocol.TBinaryProtocol(transport)
client = Hbase.Client(protocol)
transport.open()
scan = TScan()
tableName = 'test'
id = client.scannerOpenWithScan(tableName,scan,None)
result2 = client.scannerGetList(id,10)
print result2
# End www.jb51.cc
scannerGet则是每次只取一行数据：
# @param python通过thrift操作hbase实例
# @author 编程之家 jb51.cc|jb51.cc
from thrift import Thrift
from thrift.transport import TSocket
from thrift.transport import TTransport
from thrift.protocol import TBinaryProtocol
from hbase import Hbase
from hbase.ttypes import *
transport = TSocket.TSocket('localhost',None)
result = client.scannerGet(id)
while result:
print result
result = client.scannerGet(id)
# End www.jb51.cc
