表users,有三个列族user_id,address,info

列出全部表

>list

创建表

>create‘users_tmp‘,‘user_id‘,‘address‘,‘info‘

删除表

>disable ‘users_tmp‘

>drop ‘users_tmp‘

添加记录

put ‘users‘,‘xiaoming‘,‘info:age‘,‘24‘;

put ‘users‘,‘xiaoming‘,‘info:birthday‘,‘1987-06-17‘;

put ‘users‘,‘xiaoming‘,‘info:company‘,‘alibaba‘;

put ‘users‘,‘xiaoming‘,‘address:contry‘,‘china‘;

put ‘users‘,‘zhangyifei‘,‘address:town‘,‘xianqiao‘;

获取一条记录

1.取得一个id的所有数据

>get ‘users‘,‘xiaoming‘

2.获取一个id，一个列族的所有数据
