Sentry 介绍：　https://datamining.blog.csdn.net/article/details/98969244

一、安装Sentry

１.ＭariaDB中创建sentry数据库

MariaDB [(none)]> create database sentry default character set utf8;
Query OK, 1 row affected (0.01 sec)MariaDB [(none)]> CREATE USER 'sentry'@'%' IDENTIFIED BY 'password';
Query OK, 0 rows affected (0.03 sec)MariaDB [(none)]> GRANT ALL PRIVILEGES ON sentry. * TO 'sentry'@'%';
Query OK, 0 rows affected (0.01 sec)MariaDB [(none)]> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

2.CDH中添加sentry 服务

填写刚刚创建数据库信息

继续安装完成

3.hive配置启动Sentry

启动hive Sentry

取消模拟用户身份提交

启用数据库中的存储通知

保存

4.Impala配置启动Sentry

5.Hue配置启动Sentry

6.Hdfs配置启动Sentry

启动HDFS ACL控制，与Sentry权限同步

7.重启服务，使配置生效

至此服务安装成功

二、Sentry权限测试

1.创建hive超级用户

1.1 创建kerberos hive用户

[root@xxx ~]# kadmin.local
Authenticating as principal hbase/admin@JAST.COM with password.
kadmin.local:  addprinc hive@JAST.COM
WARNING: no policy specified for hive@JAST.COM; defaulting to no policy

通过 beeline连接 hiveserver2

[root@xxx001 ~]# beeline
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=512M; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

scan complete in 2ms
Connecting to jdbc:hive2://192.168.1.101:10000/;principal=hive@JAST.COM
Kerberos principal should have 3 parts: hive@JAST.COM

这里就遇到问题了，提示 Kerberos principal should have 3 parts: hive@JAST.COM ，说是需要三个部分，翻阅资料发现创建kerberos principal指定三个部分，命名规则类似于：服务名/HOST@域名，域名就是/etc/krb5.conf 中 domain_realm 配置的，如 hive/hostname1@JAST.COM

此处参考：https://community.hortonworks.com/questions/22897/kerberos-principal-should-have-3-parts.html

注意这里hostname要与hiveserver2的相同，例：

!connect jdbc:hive2://hostname:10000/;principal=hive/hostname@JAST.COM

不相同会报错：

Error: Could not open client transport with JDBC Uri: jdbc:hive2://hostname:10000/;principal=hive/hostname1@JAST.COM: GSS initiate failed (state=08S01,code=0)

修改第一步创建principal

[root@xxx ~]# kadmin.local
Authenticating as principal hbase/admin@JAST.COM with password.
kadmin.local:  addprinc hive/hostname@JAST.COM
WARNING: no policy specified for hive/hostname@JAST.COM; defaulting to no policy

再次通过beeline连接,成功

INFO  : OK
No rows affected (0.241 seconds)

1.4 将admin角色授权给hive用户组

0: jdbc:hive2://xxx:10000/> GRANT ROLE admin TO GROUP hive;
INFO  : Compiling command(queryId=hive_20190811134242_2e020ff8-08ee-4b68-a19c-ff83b68a24ae): GRANT ROLE admin TO GROUP hive

INFO  : OK
No rows affected (0.163 seconds)

以上操作创建了一个admin角色：

admin : 具有管理员权限，可以读写所有数据库，并授权给hive组（对应操作系统的组）

2. 创建test表

使用hive用户登录Kerberos，通过beeline登录HiveServer2，创建test表，并插入测试数据

0: jdbc:hive2://xxx:10000/> create table test (s1 string, s2 string) row format delimited fields terminated by ',';
INFO  : Compiling command(queryId=hive_20190811134747_3bf78819-78e0-4f3f-921d-57aae50184ab): create table test (s1 string, s2 string) row format delimited fields terminated by ','

3. 创建其他角色，授予权限

创建两个角色：jast_r 与 jast_w ，一个是读权限，一个是写权限

注意：集群所有节点必须存在fayson和user_w用户，用户默认用户组与用户名一致，赋权是针对用户组而不是针对用户。

3.1 创建用户，默认用户组与用户名相同

[root@hostname ~]# useradd jast_r
[root@hostname ~]# id jast_r
uid=1002(jast_r) gid=1002(jast_r) 组=1002(jast_r)
[root@hostname ~]# useradd jast_w
[root@hostname ~]# id jast_w
uid=1003(jast_w) gid=1003(jast_w) 组=1003(jast_w)

3.2 授权read角色对test表的select权限，write角色对test表的insert权限

我们发现，

读用户可以读取所有内容，但是不能删除和添加hdfs中内容

写用户可以读取非hive目录下的文件，但是不能读取hive/warehouse目录下的的数据，可以写入数据，但是也不能删除数据（这个和网上部分资料说的不太相同，我又测了一下，使用hive用用户的话是可以删除的，jast_w 就是不可以）

说明hive的权限对hdfs权限是同步的

Impala与Sentry集成后可以使用Sentry来进行权限管理，拥有read角色的fayson用户组只能对test表进行select和count操作不能插入数据，拥有write角色的user_w

用户组只能对test表插入数据不能进行select和count操作。说明Sentry实现了Hive权限与Impala的同步。

4. Sentry 列权限设置

其实这里的步骤就是：创建kerberos 账号 ->创建 role -> 给role赋予相关权限 -> 给用户/用户组赋予role权限

kerberos 登录hive用户，链接hiveserver2

发现，我们只能查看我们指定的列

去hdfs查看是否有权限查看数据

[root@hostname ~]# hdfs dfs -ls /user/hive/warehouse
ls: Permission denied: user=jast_cloumn, access=READ_EXECUTE, inode="/user/hive/warehouse":hive:hive:drwxrwx--x
[root@hostname ~]# hdfs dfs -ls /user/hive
Found 3 items
drwx------   - hive hive          0 2019-08-11 15:00 /user/hive/.Trash
drwx------   - hive hive          0 2019-08-11 14:19 /user/hive/.staging
drwxrwx--x+  - hive hive          0 2019-08-11 13:47 /user/hive/warehouse

发现无权限查看hive中的数据

注意：Sentry只支持SELECT的列授权，不能用于INSERT和ALL的列授权。

#权限分为 SELECT ,INSERT ,ALL
#查看所有role
show roles;#创建role
create role role_name;#删除rolt
drop role role_name;  #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;

Hadoop Kerberos 认证下 Sentry 安装 + Sentry 权限设置使用

一、安装Sentry

１.ＭariaDB中创建sentry数据库

2.CDH中添加sentry 服务

3.hive配置启动Sentry

4.Impala配置启动Sentry

5.Hue配置启动Sentry

6.Hdfs配置启动Sentry

7.重启服务，使配置生效

二、Sentry权限测试

1.创建hive超级用户

1.1 创建kerberos hive用户
