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：

java.lang.NullPointerException
 at demo.jdbc.DemoTest.main(DemoTest.java:19)

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>

在前篇高可用高性能分布式文件系统FastDFS进阶keepalived+nginx对多tracker进行高可用热备中已介绍搭建高可用的分布式文件系统架构。那怎么在程序中调用，其实网上有很多栗子，这里在他们的基础上作个简单的介绍。下载源码并加入本地仓库官网Java客户端源代码：https://github.com/happyfish100/fastdfs-client-java 打开源码后执行maven install 将代码打成jar到本地maven仓库(这步可自行 google) 示例源码然后创建一个Demo工程，这里采用spring mvc模式创建。在pom中加入引用maven中依赖jar包  <dependency> <groupId>org.csource</groupId> <artifactId>fastdfs-client-java</artifactId> <version>1.27-SNAPSHOT<...
