標籤:

1. 進入hbase命令列  ./hbase shell

2. 顯示hbase中的表  list

3. 建立user表,包含info、data兩個列族
create ‘user‘, ‘info1‘, ‘data1‘
create ‘user‘, {NAME => ‘info‘, VERSIONS => ‘3‘}


4. 向表中插入資訊:

向user表中插入資訊,row key為rk0001,列族info中添加name列標示符,值為zhangsan
put ‘user‘, ‘rk0001‘, ‘info:name‘, ‘zhangsan‘

向user表中插入資訊,row key為rk0001,列族info中添加gender列標示符,值為female
put ‘user‘, ‘rk0001‘, ‘info:gender‘, ‘female‘

向user表中插入資訊,row key為rk0001,列族info中添加age列標示符,值為20
put ‘user‘, ‘rk0001‘, ‘info:age‘, 20

向user表中插入資訊,row key為rk0001,列族data中添加pic列標示符,值為picture
put ‘user‘, ‘rk0001‘, ‘data:pic‘, ‘picture‘


5. 擷取表中的資訊:

擷取user表中row key為rk0001的所有資訊
get ‘user‘, ‘rk0001‘

擷取user表中row key為rk0001,info列族的所有資訊
get ‘user‘, ‘rk0001‘, ‘info‘

擷取user表中row key為rk0001,info列族的name、age列標示符的資訊
get ‘user‘, ‘rk0001‘, ‘info:name‘, ‘info:age‘

擷取user表中row key為rk0001,info、data列族的資訊
get ‘user‘, ‘rk0001‘, ‘info‘, ‘data‘
get ‘user‘, ‘rk0001‘, {COLUMN => [‘info‘, ‘data‘]}
get ‘user‘, ‘rk0001‘, {COLUMN => [‘info:name‘, ‘data:pic‘]}

擷取user表中row key為rk0001,列族為info,版本號碼最新5個的資訊
get ‘people‘, ‘rk0002‘, {COLUMN => ‘info‘, VERSIONS => 2}
get ‘user‘, ‘rk0001‘, {COLUMN => ‘info:name‘, VERSIONS => 5}
get ‘user‘, ‘rk0001‘, {COLUMN => ‘info:name‘, VERSIONS => 5, TIMERANGE => [1392368783980, 1392380169184]}

擷取user表中row key為rk0001,cell的值為zhangsan的資訊
get ‘people‘, ‘rk0001‘, {FILTER => "ValueFilter(=, ‘binary:圖片‘)"}

擷取user表中row key為rk0001,列標示符中含有a的資訊
get ‘people‘, ‘rk0001‘, {FILTER => "(QualifierFilter(=,‘substring:a‘))"}

put ‘user‘, ‘rk0002‘, ‘info:name‘, ‘fanbingbing‘
put ‘user‘, ‘rk0002‘, ‘info:gender‘, ‘female‘
put ‘user‘, ‘rk0002‘, ‘info:nationality‘, ‘中國‘
get ‘user‘, ‘rk0002‘, {FILTER => "ValueFilter(=, ‘binary:中國‘)"}


6. 查詢表中資訊:

查詢user表中的所有資訊
scan ‘user‘

查詢user表中列族為info的資訊
scan ‘people‘, {COLUMNS => ‘info‘}
scan ‘user‘, {COLUMNS => ‘info‘, RAW => true, VERSIONS => 5}
scan ‘persion‘, {COLUMNS => ‘info‘, RAW => true, VERSIONS => 3}
查詢user表中列族為info和data的資訊
scan ‘user‘, {COLUMNS => [‘info‘, ‘data‘]}
scan ‘user‘, {COLUMNS => [‘info:name‘, ‘data:pic‘]}

查詢user表中列族為info、列標示符為name的資訊
scan ‘user‘, {COLUMNS => ‘info:name‘}

查詢user表中列族為info、列標示符為name的資訊,並且版本最新的5個
scan ‘user‘, {COLUMNS => ‘info:name‘, VERSIONS => 5}

查詢user表中列族為info和data且列標示符中含有a字元的資訊
scan ‘people‘, {COLUMNS => [‘info‘, ‘data‘], FILTER => "(QualifierFilter(=,‘substring:a‘))"}

查詢user表中列族為info,rk範圍是[rk0001, rk0003)的資料
scan ‘people‘, {COLUMNS => ‘info‘, STARTROW => ‘rk0001‘, ENDROW => ‘rk0003‘}

查詢user表中row key以rk字元開頭的
scan ‘user‘,{FILTER=>"PrefixFilter(‘rk‘)"}

查詢user表中指定範圍的資料
scan ‘user‘, {TIMERANGE => [1392368783980, 1392380169184]}

7. 刪除表中資料:
刪除user表row key為rk0001,列標示符為info:name的資料

delete ‘people‘, ‘rk0001‘, ‘info:name‘


刪除user表row key為rk0001,列標示符為info:name,timestamp為1392383705316的資料
delete ‘user‘, ‘rk0001‘, ‘info:name‘, 1392383705316

清空user表中的資料
truncate ‘people‘


8. 其他動作

修改表結構:
首先停用user表(新版本不用)
disable ‘user‘

添加兩個列族f1和f2
alter ‘people‘, NAME => ‘f1‘

alter ‘user‘, NAME => ‘f2‘


啟用表enable ‘user‘


###disable ‘user‘(新版本不用)
刪除一個列族:
alter ‘user‘, NAME => ‘f1‘, METHOD => ‘delete‘ 或 alter ‘user‘, ‘delete‘ => ‘f1‘

添加列族f1同時刪除列族f2
alter ‘user‘, {NAME => ‘f1‘}, {NAME => ‘f2‘, METHOD => ‘delete‘}

將user表的f1列族版本號碼改為5
alter ‘people‘, NAME => ‘info‘, VERSIONS => 5
啟用表
