beeline启动时，错误 User: root is not allowed to impersonate root

错误：

beeline>!connect jdbc:hive2://192.168.33.01:10000 root root
Connecting to jdbc:hive2://192.168.33.01:10000
Error: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User: root is not allowed to impersonate root (state=,code=0)

解决办法：

在hadoop的core-site.xml中添加以下内容 

#（虚拟机的登录用户）“root”可以代理所有主机上的所有用户
<property>
<name>hadoop.proxyuser.root.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.root.groups</name>
<value>*</value>
</property>
