进入hbase命令行
./hbase shell

显示hbase中的表
list

创建user表，包含info、data两个列族
create ‘user’, ‘info’, ‘data’
或者
create ‘user’, {NAME => ‘info’, VERSIONS => ‘3’}，{NAME => ‘data’}

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:zhangsan’)”}

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’}
