本程序主要实现hive权限测试。系统中有管理员用户single和测试用户test。在路径/home/test/下，将用例的预置条件写在input文件夹内，每个用例对应一个input文件，命名为x-y~z.q(其中xyz都是数字)；将用例需要执行的语句放在case文件夹内，命名为case_x.q;将预期结果写入expect文件夹，命名为expect_x；执行结果输出到output文件夹中，命名为x-y~z.q
执行过程：kinit single用户，beeline -u -f登录并执行input文件中对test用户对应角色回收和赋予权限的语句；kinit test用户，beeline -u -f去执行case文件夹中的测试语句并保存执行结果到output文件夹中；根据expect中是否有文件及该测试为正向或逆向测试，和output内容作比较，得出该测试pass还是fail的结果，统计测试结果。
该程序能够实现hive的权限自动化测试，但每个用例对应一个input文件、一个case文件、一个expect文件、一个output文件，太过繁杂，不好用。下一篇出python优化版本。
