背景:
1、Apache Sentry是Cloudera公司发布的一个Hadoop开源组件,它提供了细粒度级、基于角色的授权以及多租户的管理模式,
2、Sentry当前可以和Hive/Hcatalog、Apache Solr 和Cloudera Impala集成, 为这些组件提供权限管理服务。
3、基于角色的管理(role-based acess control)通过创建角色,将每个组件的权限授予给此角色,然后在用户(组)中添加此角色,用户便具备此角色访问组件的权限,
4、使用sentry对hive进行权限管理时,这里的组件可以是整个server,也可以是单个db,或者单张table.

测试如下:
1.1 查看全部数据库
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "show databases;"

我尝试的先创建一个库 报错如下:
[hadoop@uhadoop-4wvgxxla-master2 ~]$ beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "create database test;"
Transaction isolation: TRANSACTION_REPEATABLE_READ
Error: Error while compiling statement: FAILED: SemanticException No valid privileges
User hive does not have privileges for CREATEDATABASE   用户配置单元没有CREATEDATABASE的特权
The required privileges: Server=uhadoop-4wvgxxla-master1->action=create->grantOption=false; (state=42000,code=40000)
Closing: 0: jdbc:hive2://uhadoop-4wvgxxla-master2:10000

1.2 查看全部角色
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "show roles;"
Transaction isolation: TRANSACTION_REPEATABLE_READ
+-------+
| role  |
+-------+
+-------+
No rows selected (1.151 seconds)
Beeline version 2.3.3 by Apache Hive
Closing: 0: jdbc:hive2://uhadoop-4wvgxxla-master2:10000
// 用户角色为空

1.3 查看当前角色
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "show current roles;"
Driver: Hive JDBC (version 2.3.3)
Transaction isolation: TRANSACTION_REPEATABLE_READ
+-------+
| role  |
+-------+
+-------+
No rows selected (0.446 seconds)
Beeline version 2.3.3 by Apache Hive
Closing: 0: jdbc:hive2://uhadoop-4wvgxxla-master2:10000
// 显示当前没有任何的角色

1.4 查看当前用户
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "select current_user();"
Driver: Hive JDBC (version 2.3.3)
Transaction isolation: TRANSACTION_REPEATABLE_READ
+-------+
|  _c0  |
+-------+
| hive  |
+-------+
1 row selected (1.124 seconds)
Beeline version 2.3.3 by Apache Hive
Closing: 0: jdbc:hive2://uhadoop-4wvgxxla-master2:10000

// 当前操作hiveserver2的用户是hive

  1. hive用户授予管理员权限
    2.1 创建管理员角色admin
    beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "CREATE ROLE admin;"

2.2 为admin角色授予全部server权限
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive        // 进入到hiveserver2的内部之后执行如下:
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> grant all on server uhadoop-4wvgxxla-master1 to role admin;
No rows affected (0.491 seconds)

2.3 为hive用户赋予admin角色
//经过这一步,hive用户已经可以作为管理员用户执行全部数据和权限操作。
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "GRANT ROLE admin TO GROUP hive;"

create table student(
Sno char(9) COMMENT '用户ID',
Sname char(20) ,
Ssex char(2),
Sage int,
Sdept char(20)
);

insert into student values(200215121,'李勇','男',20,'CS');

没有出现中文乱码的问题,请测
验证方式需要:
show create table xxx;
desc xxx;
desc formatted xxx;
查看3种方式是不是都没有中文乱码的问题

  1. 创建测试数据库(使用hive用户创建)
    3.1 创建测试db1,db2
    //使用管理员用户登陆,创建db1,db2两个数据库。
    beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "create database db1;create database db2;"

// 创建测试表,并插入数据

beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "create table db1.t1(id string);"

beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "insert into  db1.t1  values ('t1_001'),('t1_002');"

beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "create table db2.t2(id string);"

beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "insert into  db2.t2  values ('t2_001'),('t2_002');"

0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> use db1;
No rows affected (0.173 seconds)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show tables;
+-----------+
| tab_name  |
+-----------+
| t1        |
+-----------+
1 row selected (0.208 seconds)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> select * from t1;
+---------+
|  t1.id  |
+---------+
| t1_001  |

0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> select * from db2.t2;
+---------+
|  t2.id  |
+---------+
| t2_001  |
| t2_002  |
+---------+
2 rows selected (0.304 seconds)

3.2 master1,master2节点上创建linux测试用户user1, user2
useradd -M -s /sbin/nologin user1

useradd -M -s /sbin/nologin user2

cat /etc/passwd
user1:x:1004:1005::/home/user1:/sbin/nologin
user2:x:1005:1006::/home/user2:/sbin/nologin

3.3 hive中创建两个角色,分别授予不同的角色权限
//创建角色role1, 授予其对db1的管理权限
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "CREATE ROLE role1;"
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "grant all on database db1 to role role1 with grant option;"

//创建角色role2, 授予其对db2的管理权限
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "CREATE ROLE role2;"
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "grant all on database db2 to role role2 with grant option;"

// show grant role role1; (查看role1角色的权限列表)
// show grant role role2; (查看role2角色的权限列表)

0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show grant role role1;
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
| database  | table  | partition  | column  | principal_name  | principal_type  | privilege  | grant_option  |   grant_time   | grantor  |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
| db1       |        |            |         | role1           | ROLE            |          | true          | 1583739035000  | --       |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
1 row selected (0.215 seconds)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show grant role role2;
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
| database  | table  | partition  | column  | principal_name  | principal_type  | privilege  | grant_option  |   grant_time   | grantor  |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
| db2       |        |            |         | role2           | ROLE            |
         | true          | 1583739057000  | --       |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
1 row selected (0.119 seconds)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show grant role admin;
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
| database  | table  | partition  | column  | principal_name  | principal_type  | privilege  | grant_option  |   grant_time   | grantor  |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
|         |        |            |         | admin           | ROLE            |          | false         | 1583737318000  | --       |
+-----------+--------+------------+---------+-----------------+-----------------+------------+---------------+----------------+----------+
1 row selected (0.131 seconds)

3.4 管理员用户登陆hive,为两个用户赋予不同的角色
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "GRANT ROLE role1 TO GROUP user1;"

beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n hive -e "GRANT ROLE role2 TO GROUP user2;"

// show role grant group user1 (查看user1的角色列表)
// show role grant group user2(查看user2的角色列表)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show role grant group user1;
+--------+---------------+-------------+----------+
|  role  | grant_option  | grant_time  | grantor  |
+--------+---------------+-------------+----------+
| role1  | false         | 0           | --       |
+--------+---------------+-------------+----------+
1 row selected (0.144 seconds)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show role grant group user2;
+--------+---------------+-------------+----------+
|  role  | grant_option  | grant_time  | grantor  |
+--------+---------------+-------------+----------+
| role2  | false         | 0           | --       |
+--------+---------------+-------------+----------+
1 row selected (0.125 seconds)

4 使用user1, user2用户登陆,验证权限隔离
//user1登陆,只能看到db1数据库
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n user1 -e "show databases;"

// user2用户登陆,只能看到db2数据库
beeline -u "jdbc:hive2://uhadoop-4wvgxxla-master2:10000"  -n user2 -e "show databases;"

  1. 其他使用测试
    5.1 将role从角色中剔除
    REVOKE ROLE role1 FROM GROUP user1;
    删除role
    //先查看角色列表
    show roles

// 删除角色
drop role role2;

角色权限撤销
// 先查看角色当前授权信息
show grant role role1;

// 将db1的操作权限从role1撤销
revoke all on database db1 from role role1;

授权语句说明:
角色授权和撤销
GRANT ROLE role_name [, role_name] TO GROUP [,GROUP ]
REVOKE ROLE role_name [, role_name] FROM GROUP [,GROUP ]

权限的授予和撤销
GRANT [, ] ON TO ROLE [,ROLE ]
REVOKE [, ] ON FROM ROLE [,ROLE ]

查看角色/组权限
SHOW ROLES;
SHOW CURRENT ROLES;
SHOW ROLE GRANT GROUP ;
SHOW GRANT ROLE ;
SHOW GRANT ROLE on OBJECT ;


查看所有的角色
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show roles;
+--------+
|  role  |
+--------+
| admin  |
| role1  |
| role2  |
+--------+
3 rows selected (0.12 seconds)

#将某个数据库读权限授予给某个role
GRANT SELECT ON DATABASE db_name TO ROLE role_name;

#将test 表的 S1 列的读权限授权给role_name (TABLE也可以不写)
GRANT SELECT(s1) ON TABLE test TO ROLE role_name;

#test表的select 权限给 role_name 角色
GRANT SELECT ON TABLE test TO ROLE role_name;

例子:
目前有2个用户
user1   // 有db1下t1 表的所有权限
user2   // 有db2下t2 表的所有权限

目前有角色
+--------+
|  role  |
+--------+
| admin  |   //所有库的最高权限 all
| role1  |   // 只有db1库的所有权限
| role2  |  // 只有db2库下的所有权限
+--------+

接下来,我有个需求,我想把temp下的student表给user2开放
首先user2对于的role2角色要有temp库的select权限
然后再把temp库下的student表的select权限给到role2 这个角色
那么user2属于role2 角色下 自然就有了temp下的student表的select权限

GRANT SELECT ON TABLE temp.student TO ROLE role2;

0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> GRANT SELECT ON TABLE temp.student TO ROLE role2;
No rows affected (0.145 seconds)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show role grant group user2;
+--------+---------------+-------------+----------+

+--------+---------------+-------------+----------+
1 row selected (0.129 seconds)
0: jdbc:hive2://uhadoop-4wvgxxla-master2:1000> show grant role role2;
