【报错】
Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException): User:xiaosiis not allowed to impersonate anonymous
【解决】
hadoop 下的 etc/hadoop/core-site.xml
加入配置信息
<property>
<name>hadoop.proxyuser.root.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.root.groups</name>
<value>*</value>
</property>
运行时用root登录
