用DataGrip连接hive时报错：User: root is not allowed to impersonate plck5，解决方法

你可以尝试关闭主机校验

修改hive安装目录下conf/hive-site.xml,将hive.server2.enable.doAs设置成false

<property>
    <name>hive.server2.enable.doAs</name>
    <value>false</value>
    <description>
      Setting this property to true will have HiveServer2 execute
      Hive operations as the user making the calls to it.
    </description>
  </property>

然后就可以成功
