eclipse导入hadoop示例源码on ubuntu14.04

hadoop自带了example程序，给我们分析map-reduce程序带了许多方便，本文讲述怎么在eclipse导入example.jar源代码 on ubuntu14.04：

1.　将hadoop自带的包导入到eclipse：

在新建的工程中，右键工程名->properties->java build path->Libraries->add External Jars

把hadoop目录下的share/hadoop/mapreduce/hadoop-mapreduce-example2.7.1.jar导入进来

2. 在导入进来的hadoop-mapreduce-example2.7.1.jar右键 -> properties-> java source attachment -> External location 

选择hadoop目录下的share/hadoop/mapreduce/source//hadoop-mapreduce-example2.7.1-source.jar

OK啦！
