org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException)

               

Error: User: hadoop is not allowed to impersonate hadoop

Stack trace for the error was (for debug purposes):
--------------------------------------
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: xx is not allowed to impersonate xx

  Hadoop配置文件 core-site.xml错误
             
 
 
    hadoop.proxyuser.admin.hosts
     *
 

 
   
        hadoop.proxyuser.admin.groups
         *
   

解决方案：将admin改为xx。

PS：集群所有节点都需要配置，配置完成后需要重启节点，否则不生效。
