以前连接的时候是没有问题的，但是今天想用一下突然发现hive连接不上去，发现10000端口并没有被占用

[centos@s101 ~]$ netstat -anop | grep 10000
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
[centos@s101 ~]$

从第一段代码报错来看。并没有权限问题
求告知如何解决

经过查看日志发现 还是

经过查找网上的资料
修改hive的配置文件即可解决

	
		hive.server2.enable.doAs
		false
	

多查看日志！！！！！
