User root is not allowed to impersonate anonymous

User root is not allowed to impersonate anonymous

ava.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: wulei is not allowed to impersonate hadoop), serverProtocolVersion:null) (state=08S01,code=0)

使用HiveServer2 and Beeline模式运行时，启动好HiveServer后运行

beeline -u jdbc:hive2://localhost:10000 -n root 链接server时

出现

java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): 

User root is not allowed to impersonate anonymous 错误。

• 修改hadoop 配置文件 etc/hadoop/core-site.xml,加入以下配置项

<property>     <name>hadoop.proxyuser.root.hosts</name>     <value>*</value> </property> <property>     <name>hadoop.proxyuser.root.groups</name>     <value>*</value> </property>

 

    hadoop.proxyuser.root.hosts配置项名称中root部分为报错User:* 中的用户名部分,如wulei!!!!!!!

    例如User: zhaoshb is not allowed to impersonate anonymous则须要将xml变动为以下格式

<property>     <name>hadoop.proxyuser.zhaoshb.hosts</name>     <value>*</value> </property> <property>     <name>hadoop.proxyuser.zhaoshb.groups</name>     <value>*</value> </property>

 

• 重启hadoop
• 测试:./beeline -u 'jdbc:hive2://localhost:10000/userdb' -n username(替换为上述的用户名部分)
