Question

我的应用程序使用hive-jdbc执行配置单元查询，但是我得到以下异常。

Failed to open new session: java.lang.RuntimeException: java.lang.RuntimeException: org.apache.hadoop.security.AccessControlException: Permission denied: user=anonymous, access=EXECUTE, inode="/tmp/hive-suser":suser:supergroup:drwxrwx---

但我的/ tmp / hive-suser权限是

"drwxrwxrwx - suser supergroup 0 2017-09-07 21:58 /tmp/hive-suser"

为什么许可不同？
为什么会发生异常错误？

Answer 1

用户匿名=

您未经过suser或supergroup组

的部分身份验证

权限设置为drwxrwx---，因此我不确定您是如何检查的，但这意味着除了用户或群组之外无人可以访问

org.apache.hadoop.security.AccessControlException：权限被拒绝
