python hbase thrift

创建hbase表:

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()

插入数据：

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)

获取一行数据：

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

返回多行则需要使用scan：

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

scannerGet则是每次只取一行数据：

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)

result = client.scannerGet(id)

while result:

    print result

    result = client.scannerGet(id)
