今天使用JDBC来操作Hive时,首先启动了hive远程服务模式:hiveserver2 &(表示后台运行),然后到eclipse中运行程序时出现错误:

主要报错内容是:java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException:User: root is not allowed to impersonate anonymous
解决办法:通过httpfs协议访问rest接口,以root用户包装自己用户的方式操作HDFS
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> <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>
