我是hadoop新手。我试过通过linux终端运行wordcount和pi等示例程序。现在想用eclipse来尝试这些程序。有人能分享一下如何配置eclipse进行hadoop开发吗？我在ubuntu 14.04 lts虚拟机上使用Hadoop2.6.0。

您可以在eclipse中创建一个maven项目，并将以下依赖项添加到pom.xml并保存该文件。它将构建工作区并将所有hadoopjar添加到库中。

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-core</artifactId>
<version>1.2.1</version>
</dependency>

谢谢你的回复！！。
我在以下目录中发现了类似的jar：
$hadoop\u主页/共享/hadoop/公用/
$hadoop\u主页/share/hadoop/hdfs
$hadoop\u主页/share/hadoop/mapreduce
$hadoop\u主页/共享/hadoop/yarn
我创建了一个用户库，并将其添加到我的eclipse项目的javabulidpath中，并成功地执行了该程序！。我还发现这个链接很有用：http://www.kishorer.in/2014/10/running-wordcount-mapreduce-example-in.html

您只需要在将要使用hadoop的eclipse项目中引用这些库。仅此而已。
