在安装hive过程中遇到了hive权限错误：

解决办法：

<property> ?

? <name>hive.metastore.authorization.storage.checks</name> ?

? <value>true</value> ?

? <description>Should the metastore do authorization checks against ?

? the underlying storage for operations like drop-partition (disallow ?

? the drop-partition if the user in question doesn't have permissions ?

? to delete the corresponding directory on the storage).</description> ?

</property> ?

Hive会尽可能地将hive.metastore.execute.setugi设置成true。在不安全的模式,将这个属性设置为true将导致metastore执行DFS操作定义用户和组权限。
