从第三个cause by的Original Exception可以看出登陆Mysql数据库被拒绝，想到root@hadoop1可能没有权限，

进入mysql查看一下：

mysql> select user,host from mysql.user;
+------+-----------+
| user | host      |
+------+-----------+
| root | %         |
| root | 127.0.0.1 |
| root | hadoop1   |
| root | localhost |
+------+-----------+
4 rows in set (0.01 sec)
  
//给root@'hadoop1'赋权限
mysql> grant all privileges on *.* to root@'hadoop1' identified by 'root';
Query OK, 0 rows affected (0.01 sec)

mysql> exit
Bye
[hadoop@hadoop1 conf]$ hive   //启动正常
