1、HBase提供了一个shell的终端给用户交互

HBase的Shell命令-LMLPHP

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','';
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:
.取得一个id的所有数据:
>get 'users','xiaoming' .获取一个id,一个列族的所有数据:
>get 'users','xiaoming','info' .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' ,''
>get 'users','xiaoming','info:age'
>put 'users','xiaoming','info:age' ,''
>get 'users','xiaoming','info:age'
获取单元格数据的版本数据:
>get 'users','xiaoming',{COLUMN=>'info:age',VERSIONS=>}
>get 'users','xiaoming',{COLUMN=>'info:age',VERSIONS=>}
>get 'users','xiaoming',{COLUMN=>'info:age',VERSIONS=>}
获取单元格数据的某个版本数据
〉get 'users','xiaoming', {COLUMN=>'info:age',TIMESTAMP=>}
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'
