Question

从Presto（AWS EMR）查询时，我遇到一个奇怪的问题。我使用的是Presto 0.194，一切正常，升级到0.224后，我无法运行查询。我正在使用LDAP身份验证进行身份验证，还使用了一个使用Authorization.json文件的Hive文件基础授权。我正在使用相同的json文件，该文件在旧版本中运行良好。任何帮助将不胜感激。

错误：查询20191005_104119_00006_3snge失败：访问被拒绝：视图所有者“用户名”无法创建从...中选择的视图。

这意味着username在特定表上没有GRANT_SELECT特权。

影响您的特定更改在0.199版本中加入： https://github.com/prestosql/presto/commit/6ed1ed88083baef1d29171364297631962adf05d 这是一个错误修复（创建视图应该要求不同的特权），因此，有意（尽管很不方便）更改并未保持向后兼容性。

顺便说一句对于一次性故障排除式的问题，这些问题不太可能对SO社区有利，我建议在Presto Community Slack上使用#troubleshooting频道

拒绝访问-EMR Presto-基于文件的授权
