Beeline version 3.1.3 by Apache Hive

解决：
1:在hadoop/etc/hadoop目录下的core-site.xml文件添加下列参数
配置root(超级⽤户)允许通过代理的⽤户

vim core-site.xml

    hadoop.proxyuser.root.hosts
    *


    hadoop.proxyuser.root.groups
    *

2:hive/conf目录hive-site.xml添加下列参数
默认情况下，HiveServer2 以提交查询的用户身份执行查询处理。但是如果以下参数设置为false，则查询将以hiveserver2进程运行的用户身份运行。
默认为true

hive.server2.enable.doAs
false

hive.server2.enable.doAs设置成false，yarn作业获取到的hiveserver2用户都为hive用户，true为实际提交作业的用户。
