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‘
