折腾了3天终于把hue集成sentry研究明白了
安装Sentry
启动Sentry，首先要安装：
1. 安装sentry服务；
2. 在hive中搜索sentry service，点选Sentry；同时需要关掉hive的imperson；
3. 设置sentry.hive.testing.mode；如果不配置，执行sql语句在HUE中报错（java中通过jdbc访问直接返回NULL）：Errorwhile compiling statement: FAILED: InvalidConfigurationExceptionhive.server2.authentication can't be none in non-testing mode
配置方式：
在hive的配置中搜索“Service-Wide advanced”，会有很多，看说明如下列：
“Hive Service Advanced Configuration Snippet (Safety Valve) forsentry-site.xml”
然后在value中添加
<property>
<name>sentry.hive.testing.mode</name>
<value>true</value>
</property>
创建角色
Error while compiling statement: FAILED: SemanticException No validprivileges User hive does not have privileges for SWITCHDATABASE The requiredprivileges:Server=server1->Db=*->Table=+->Column=*->action=select;Server=server1->Db=*->Table=+->Column=*->action=insert;
当你通过beeline以及!connectjdbc:hive2://localhost:10000/ hive hive进入到hive命令行之后，通过show roles可以发现当前没有角色；没有角色就没有权限；下面的SQL语句就是为hive用户赋予了管理员权限；GRANT ALL就是讲所有的权限赋予了admin角色，然后将hive用户和admin角色绑定。
