启动hive server2服务之后使用beeline链接报一下错误
beeline> !connect jdbc:hive2://localhost:10000
Connecting to jdbc:hive2://localhost:10000

Error: Could not open client transport with JDBC Uri: jdbc:hive2://localhost:10000: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: hadoop is not allowed to impersonate hadoop (state=08S01,code=0)
问题定位:
原因：hiveserver2增加了权限控制，需要在hadoop的配置文件中配置
解决方法：
在hadoop的core-site.xml配置文件中添加一下配置内容
<property>
<name>hadoop.proxyuser.hadoop.hosts</name>
<value></value>
</property>
<property>
<name>hadoop.proxyuser.hadoop.groups</name>
<value></value>
</property>
之后重启hadoop即可

登录测试：
可见登录成功
测试已存在的库
