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>
