解决方法：

首先需要开启rest接口，在hdfs-site.xml文件中加入：

<property>
  <name>dfs.webhdfs.enabled</name>  
  <value>true</value>  
</property>    

然后在core-site.xml文件中加入：

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

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