HBase添加、更新表数据,hbase添加表数据


1、在hbase shell中添加一行数据,命令如下:

put 'tablename','row','colfamily:colname','value'

向emp表中添加几行数据:

put 'emp','1','personal data:name','lsj'
put 'emp','1','personal data:city','zz'
put 'emp','1','professional data:designation','programmer'
put 'emp','1','professional data:salary','5000'

插入两行数据之后,查看表中的数据,如下:

2、使用python thrift API方式插入数据,代码如下:

    # coding=utf-8
    from thrift.transport.TSocket import TSocket
    from thrift.transport.TTransport import TBufferedTransport
    from thrift.protocol import TBinaryProtocol
    from hbase import Hbase

    from hbase.ttypes import *

    # 主机地址及端口号,端口号默认为9090
    host = '192.168.83.135'
    port = 9090

    # 初始化链接
    transport = TBufferedTransport(TSocket(host, port))
    transport.open()
    protocol = TBinaryProtocol.TBinaryProtocol(transport)

    # 创建客户端
    client = Hbase.Client(protocol)
    client.mutateRow('empbypy','1',[Mutation(column='personal data:city',value='zz')])
    client.mutateRow('empbypy','1',[Mutation(column='personal data:name',value='lsj')])
    client.mutateRow('empbypy','1',[Mutation(column='professional data:designation',value='programmer')])
    client.mutateRow('empbypy','1',[Mutation(column='professional data:salary',value='5000')])

    transport.close()

程序运行之后,在hbase shell 中查看如下:

后期修改:在thrift官网下载的hbase包已经不能用了,只需要使用pip安装hbase-thrift即可。
3、更新表数据与插入表数据一样,都使用put命令,如下:
put ‘tablename’,’row’,’colfamily:colname’,’newvalue’
更新emp表中row为1,将列为personal data:city的值更改为bj
put ‘emp’,’1’,’personal data:city’,’bj’

4、使用python thrift API更新数据,代码如下:

    # coding=utf-8
    from thrift.transport.TSocket import TSocket
    from thrift.transport.TTransport import TBufferedTransport
    from thrift.protocol import TBinaryProtocol
    from hbase import Hbase

    from hbase.ttypes import *

    # 主机地址及端口号,端口号默认为9090
    host = '192.168.83.135'
    port = 9090

    # 初始化链接
    transport = TBufferedTransport(TSocket(host, port))
    transport.open()
    protocol = TBinaryProtocol.TBinaryProtocol(transport)

    # 创建客户端
    client = Hbase.Client(protocol)
    client.mutateRow('empbypy','1',[Mutation(column='personal data:city',value='bj')])

    transport.close()

更新结果如下图所示:
