19.2.20HBase的shell操作

Shell操作
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\’, {NAME => \’info\’, VERSIONS => \’3\’} #有多个版本

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\’
