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\’
