HIVE:Hive启动 beeline 客户端失败的解决方法

报错如下：

21/12/16 15:12:34 [main]: WARN jdbc.HiveConnection: Failed to connect to hadoop100:10000
Could not open connection to the HS2 server. Please check the server URI and if the URI is correct, then ask the administrator to check the server status.
Error: Could not open client transport with JDBC Uri: jdbc:hive2://hadoop100:10000: java.net.ConnectException: 拒绝连接 (Connection refused) (state=08S01,code=0)

原因：hadoop没设置权限

配置hadoop中的core-site.xml文件，允许hive访问

 
 
     hadoop.proxyuser.atguigu.hosts
     *
 
 
     hadoop.proxyuser.atguigu.groups
     *
 

配置完成之后，需要重启整个hadoop集群。
