Hive连接hiveserver2时报错User: hadoop is not allowed to impersonate hadoop:14:13

解决：vim $HADOOP_HOME/etc/hadoop/core-site.xml，添加如下配置项

  1. <property>
  2.   <name>hadoop.proxyuser.hadoop.hostsname>
  3.   <value>*value>
  4. </property>
  5. <property>
  6.   <name>hadoop.proxyuser.hadoop.groupsname>
  7.  <value>hadoopvalue>
  8. </property>

重新加载配置项：

  1. bin/hdfs dfsadmin –refreshSuperUserGroupsConfiguration
  2. bin/yarn rmadmin –refreshSuperUserGroupsConfiguration

如果集群配置了HA，重新加载方式：

  1. bin/hadoop dfsadmin -fs hdfs://hanode1:9000 –refreshSuperUserGroupsConfiguration
  2. bin/hadoop dfsadmin -fs hdfs://hanode2:9000 –refreshSuperUserGroupsConfiguration
