使用beeline 连接客户端报错

当hive数据仓库搭建起来了，同时将hiveserver2 服务器端已启动（命令：./hiveserver2） ，使用 beeline   命令启动客户端  报一下这个错误： 
Beeline version 1.2.1 by Apache Hive

0: jdbc:hive2://192.168.173.128:10000 (closed)>  

解决办法：   

这里明显就是因为权限的问题，而我这里使用是yarn 集群的hadoop  ，hadoop集群的用户（ hadoop ）是linux系统的子用户 。所以使用beeline登录时，用户名应该是hadoop 不是root ，即： Enter username for jdbc:hive2://192.168.173.128:10000: root  这里输入用户名时改为： hadoop，便不会再报错了
