hbase的基本操作

进入hbase命令行

./hbase shell

查看状态

status

显示hbase中的表

list

创建user表，包含info、data两个列族

create ‘user‘, ‘info1‘, ‘data1‘

create ‘user‘, {NAME => ‘info‘, VERSIONS => ‘3‘}

向user表中插入信息，row key为rk0001，列族info中添加name列标示符，值为zhangsan

put ‘user‘, ‘rk0001‘, ‘info:name‘, ‘zhangsan‘

向user表中插入信息，row key为rk0001，列族info中添加gender列标示符，值为female

put ‘user‘, ‘rk0001‘, ‘info:gender‘, ‘female‘

向user表中插入信息，row key为rk0001，列族info中添加age列标示符，值为20

put ‘user‘, ‘rk0001‘, ‘info:age‘, 20

向user表中插入信息，row key为rk0001，列族data中添加pic列标示符，值为picture

put ‘user‘, ‘rk0001‘, ‘data:pic‘, ‘picture‘

获取user表中row key为rk0001的所有信息

get ‘user‘, ‘rk0001‘

获取user表中row key为rk0001，info列族的所有信息

get ‘user‘, ‘rk0001‘, ‘info‘

获取user表中row key为rk0001，info列族的name、age列标示符的信息

get ‘user‘, ‘rk0001‘, ‘info:name‘, ‘info:age‘

获取user表中row key为rk0001，info、data列族的信息

get ‘user‘, ‘rk0001‘, ‘info‘, ‘data‘

get ‘user‘, ‘rk0001‘, {COLUMN => [‘info‘, ‘data‘]}

get ‘user‘, ‘rk0001‘, {COLUMN => [‘info:name‘, ‘data:pic‘]}

获取user表中row key为rk0001，列族为info，版本号最新5个的信息

get ‘user‘, ‘rk0001‘, {COLUMN => ‘info‘, VERSIONS => 2}

get ‘user‘, ‘rk0001‘, {COLUMN => ‘info:name‘, VERSIONS => 5}

get ‘user‘, ‘rk0001‘, {COLUMN => ‘info:name‘, VERSIONS => 5, TIMERANGE => [1392368783980, 1392380169184]}

获取user表中row key为rk0001，cell的值为zhangsan的信息

get ‘people‘, ‘rk0001‘, {FILTER => "ValueFilter(=, ‘binary:图片‘)"}

获取user表中row key为rk0001，列标示符中含有a的信息

get ‘people‘, ‘rk0001‘, {FILTER => "(QualifierFilter(=,‘substring:a‘))"}

put ‘user‘, ‘rk0002‘, ‘info:name‘, ‘fanbingbing‘

put ‘user‘, ‘rk0002‘, ‘info:gender‘, ‘female‘

put ‘user‘, ‘rk0002‘, ‘info:nationality‘, ‘中国‘

get ‘user‘, ‘rk0002‘, {FILTER => "ValueFilter(=, ‘binary:中国‘)"}

查询user表中的所有信息

scan ‘user‘

查询user表中列族为info的信息

scan ‘user‘, {COLUMNS => ‘info‘}

scan ‘user‘, {COLUMNS => ‘info‘, RAW => true, VERSIONS => 5}

scan ‘persion‘, {COLUMNS => ‘info‘, RAW => true, VERSIONS => 3}

查询user表中列族为info和data的信息

scan ‘user‘, {COLUMNS => [‘info‘, ‘data‘]}

scan ‘user‘, {COLUMNS => [‘info:name‘, ‘data:pic‘]}

查询user表中列族为info、列标示符为name的信息

scan ‘user‘, {COLUMNS => ‘info:name‘}

查询user表中列族为info、列标示符为name的信息,并且版本最新的5个

scan ‘user‘, {COLUMNS => ‘info:name‘, VERSIONS => 5}

查询user表中列族为info和data且列标示符中含有a字符的信息

scan ‘user‘, {COLUMNS => [‘info‘, ‘data‘], FILTER => "(QualifierFilter(=,‘substring:a‘))"}

查询user表中列族为info，rk范围是[rk0001, rk0003)的数据

scan ‘people‘, {COLUMNS => ‘info‘, STARTROW => ‘rk0001‘, ENDROW => ‘rk0003‘}

查询user表中row key以rk字符开头的

scan ‘user‘,{FILTER=>"PrefixFilter(‘rk‘)"}

查询user表中指定范围的数据

scan ‘user‘, {TIMERANGE => [1392368783980, 1392380169184]}

删除数据

删除user表row key为rk0001，列标示符为info:name的数据

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

删除user表row key为rk0001，列标示符为info:name，timestamp为1392383705316的数据

delete ‘user‘, ‘rk0001‘, ‘info:name‘, 1392383705316

清空user表中的数据

truncate ‘people‘

修改表结构

首先停用user表（新版本不用）

disable ‘user‘

添加两个列族f1和f2

alter ‘people‘, NAME => ‘f1‘

alter ‘user‘, NAME => ‘f2‘

启用表

enable ‘user‘

###disable ‘user‘(新版本不用)

删除一个列族：

alter ‘user‘, NAME => ‘f1‘, METHOD => ‘delete‘ 或 alter ‘user‘, ‘delete‘ => ‘f1‘

添加列族f1同时删除列族f2

alter ‘user‘, {NAME => ‘f1‘}, {NAME => ‘f2‘, METHOD => ‘delete‘}

将user表的f1列族版本号改为5

alter ‘people‘, NAME => ‘info‘, VERSIONS => 5

启用表

enable ‘user‘

删除表

disable ‘user‘

drop ‘user‘
