解决办法：
配置core-site.xml和httpfs-site.xml时，通过命令找出应该配置哪个用户。

$HIVE_HOME/bin/beeline -u 'jdbc:hive2://localhost:10000/db_hive_test' -n hadoop  -p hadoop

如果正常，则应该配置为hadoop.proxyuser.hadoop.hosts，如

<property>
 <name>hadoop.proxyuser.hadoop.hosts</name>
  <value>*</value>
</property>
<property>
  <name>hadoop.proxyuser.hadoop.groups</name>
  <value>*</value>
</property>
