看问题：beeline连接hiveserver2报错。连接串：hive  --service beeline -u jdbc:hive2://s1:10000/hive

错误：Error: Could not open client transport with JDBC Uri: jdbc:hive2://s1:10000/hive: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: xxx  is not allowed to impersonate anonymous (state=08S01,code=0)

解决方式：在hadoop的配置文件core-site.xml增加如下配置，重启hdfs，其中“xxx”是连接beeline的用户，将“xxx”替换成自己的用户名即可

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

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

　　

 

“*”表示可通过超级代理“xxx”操作hadoop的用户、用户组和主机
