配置hive server2鉴权和beeline无密码链接hive数据仓库

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
Enter username for jdbc:hive2://localhost:10000: hadoop
Enter password for jdbc:hive2://localhost:10000: **
19/03/01 22:01:59 [main]: WARN jdbc.HiveConnection: Failed to connect to 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
