• 基本。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

##进入shell

>>hbase shell

##查看状态

>>status

##查看版本

>>version

##创建表  表名: member; 列族: member_id ,address, infor

>>create 'member','member_id','address','info'

##查看所有表

>>list

##查看表的信息

>>descripe 'member'

• 删除。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

##删除列族‘member_id’

>>alter 'member',{NAME=>'member_id',METHOD=>'delete'}

#####出错：ERROR: org.apache.hadoop.hbase.TableNotDisabledException: 

#####先要将table进行disable操作（离线）

>>disable 'member'

>>alter 'member',{NAME=>'member_id',METHOD=>'delete'}

#####重新让表可用enable(在线)

>>enable 'member'

##删除表

>>disable ‘member’

>>drop 'member'

##查看表是否存在

>>exists 'member'

##查看表是否enable（在线）

>>is_enabled 'member'

##查看表是否disable（离线）

>>is_disabled 'member'

## 删除指定行键的字段

>>delete 'member','201401','info:age'

>>get 'member','201401','info'

-----------------------------------------------------------------------------

hbase(main):017:0> delete 'member','201401','info:age'
0 row(s) in 0.0080 seconds

hbase(main):018:0> get 'member','201401','info'

info:birthday          timestamp=1415240002266, value=1987-06-17
info:company           timestamp=1415240043955, value=alibaba
2 row(s) in 0.0420 seconds

-----------------------------------------------------------------------------

## 删除整行

>> deleteall 'member','201401'

>>get 'member','201401'

-----------------------------------------------------------------------------

hbase(main):023:0> deleteall 'member','201401'

• 插入。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

##插入数据

## ‘member’: 表名;  

## ‘201401’:   行键; 

## 'info.age':  指定列族info中age列;

## ‘24’: 值

>>put 'member','201401','info:age','24'

>>put 'member','201401','info:age','25'

>>put 'member','201401','info:birthday','1987-06-17'

>>put 'member','address:city','shangrao'

>>put 'member','201402','address:city','shangrao'

>>put 'member','201402','address:town','yushan'

• 查寻。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。

##查寻表有多少行

>>count 'member'

##查寻数据

####按照 行键查寻

>>get 'member','201401'

-----------------------------------------------------------------------------

hbase(main):049:0> get 'member','201401'
COLUMN                  CELL
address:city           timestamp=1415240104894, value=hangzhou
