问题描述：
Amabri 2.7.4 hive 3.1.0
hive Authorization用了默认 ，试过sqlstdauth也报错
hive执行添加udf命令报错
Error: Error while compiling statement:FAILED: HiveAccessControlException Permission denied:
Principal [name=root,type=USER] does not have following privileges for operation ......
> add jar /opt/hiveudf-1.0-SNAPSHOT.jar;
Error: Error while processing statement:
Failed to retrieve roles for root: Metastore Authorization api invocation for remote metastore is disabled in this configuration.
Run commands via jdbc/odbc clients via HiveServer2 that is using embedded metastore. (state=,code=1)
可能add jar包成功 但是 创建自定义函数失败 报权限不够
>create function aisino.myUUID as 'aisino_udf.UUIDFunction' using jar 'hdfs:/user/hive/UUID.jar';
Error: Error while compiling statement: FAILED: HiveAccessControlException Permission denied: Principal [name=root, type=USER] does not have following privileges for operation CREATEFUNCTION [ADMIN PRIVILEGE on INPUT, ADMIN PRIVILEGE on OUTPUT] (state=42000,code=40000)
网上说set role admin 可是
set role admin

解决办法：
根据错误提示
。。。。。。 先关权限认证
