HBase的hbase shell 详解

进入hbase命令行
./hbase shell
显示hbase中的表
list
创建user表，里面包含info，date两个列族
create 'user','info','data'
create 'user',{NAME => 'info', VERSIONS => 5},{NAME => 'data' , VERSIONS => 5 }

scan 'user'

创建user表，里面包含info，date两个列族
create 'user','info','data'(不指定VERSIONS时，默认VERSIONS=1)
create 'user',{NAME => 'info', VERSIONS => 5},{NAME => 'data' , VERSIONS => 5 }

向user表中插入信息，row key 值为rk0001 列族info中添加name列标识符，值为zhangsan
put 'user','rk0001','info:name','zhansan'
向user表中插入信息，row key 值为rk0001 列族info中添加gender列标识符，female
put 'user','rk0001','info:gender','female'
向user表中插入信息，row key 值为rk0001 列族info中添加age列标识符，值为18
put 'user','rk0001','info:age','18'
向user表中插入信息，row key 值为rk0001 列族info中添加pic列标识符，值为picture
put 'user','rk0001','info: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列族中的所有信息
get 'user', 'rk0001', 'info'

获取user表中，row key为rk0001，info列族中的name和age列标识符中的信息
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:age']}

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

获取user表中row key 为rk0001，cell的值为zjs的信息
get 'user', 'rk0001', {FILTER => "ValueFilter(=, 'binary:zjs')"}

后去user表中row key为rk0001，列标示符中含有’a‘的信息
get 'user', 'rk0001' ,{FILTER => "(QualifierFilter(=,'substring:z'))"}

清理user表中的数据
truncate 'user'
修改表结构
首先停用user表(新版本不需要)
disable 'user'
添加两个列族
alter 'user', NAME =>'f1'
alter 'user', NAME =>'f2'
启用表
enable 'user'


删除一个列族
disable 'user'
alter 'user' ,NAME => 'f1', METHOD => 'delete'
或者
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表中的info列族的版本号改成10
alter 'user', NAME => info , VERSIONS =>5
 disable 'user'
