Hive Questions Summary


Q : Query with transform clause is disallowed in current configuration.

在HiveSQL中使用了 TRANSFORM 函数进行特征转换, 但是执行过程中报错:

Error: Error while processing statement: FAILED: Hive Internal Error: org.apache.hadoop.hive.ql.security.authorization.plugin.HiveAccessControlException(Query with transform clause is disallowed in current configuration.) (state=08S01,code=12)

A : 目前查到的信息是在0.13.0版本之后, Hive配置了SQL标准权限验证, 在这之后不允许使用TRANSFORM语句.

The TRANSFORM clause is disallowed when SQL standard based authorization is configured in Hive 0.13.0 and later releases (HIVE-6415).
