啓動hive server2服務之後使用beeline鏈接報一下錯誤
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)
問題定位:
原因：hiveserver2增加了權限控制，需要在hadoop的配置文件中配置
解決方法：
在hadoop的core-site.xml配置文件中添加一下配置內容
<property>
<name>hadoop.proxyuser.hadoop.hosts</name>
<value></value>
</property>
<property>
<name>hadoop.proxyuser.hadoop.groups</name>
<value></value>
</property>
之後重啓hadoop即可
