HBase的hbase shell 详解
2024-05-15 01:55:01
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 }

2 row(s) in 0.0480 seconds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
