在安装hive过程中遇到了hive权限错误：

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask

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。
