1、HBase提供了一个shell的终端给用户交互

 

2、HBase Shell的DDL操作

(1)先进入HBase的 Shell命令行,即HBASE_HOME/bin/hbase shell …… >quit

创建表:
    >create 'users','user_id','address','info'    //表users,有三个列族user_id,address,info

列出全部表: >list 得到表的描述: >describe 'users' 创建表: >create 'users_tmp','user_id','address','info' 删除表: >disable 'users_tmp' >drop 'users_tmp'

(2)添加记录、获取记录、更新记录

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','xiaoming','address:province','zhejiang';
    put 'users','xiaoming','address:city','hangzhou';
    put 'users','zhangyifei','info:birthday','1987-4-17';
    put 'users','zhangyifei','info:favorite','movie';
    put 'users','zhangyifei','info:company','alibaba';
    put 'users','zhangyifei','address:contry','china';
    put 'users','zhangyifei','address:province','guangdong';
    put 'users','zhangyifei','address:city','jieyang';
    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:
    >get 'users','xiaoming','info'

3.获取一个id,一个列族中一个列的:
所有数据
    get 'users','xiaoming','info:age'
更新记录:
    >put 'users','xiaoming','info:age' ,'29'
    >get 'users','xiaoming','info:age'
    >put 'users','xiaoming','info:age' ,'30'
    >get 'users','xiaoming','info:age'
获取单元格数据的版本数据:
    >get 'users','xiaoming',{COLUMN=>'info:age',VERSIONS=>1}
    >get 'users','xiaoming',{COLUMN=>'info:age',VERSIONS=>2}
    >get 'users','xiaoming',{COLUMN=>'info:age',VERSIONS=>3}
获取单元格数据的某个版本数据
    〉get 'users','xiaoming',  {COLUMN=>'info:age',TIMESTAMP=>1364874937056}
全表扫描:
    >scan 'users'

(3)删除

删除xiaoming值的'info:age'字段:
    >delete 'users','xiaoming','info:age'
    >get 'users','xiaoming'
删除整行:
    >deleteall 'users','xiaoming'
统计表的行数:
    >count 'users'
清空表:
    >truncate 'users'
