eclipse配置hadoop插件,该如何解决
eclipse配置hadoop插件
搭了一个hadoop（0.20.2版）单机版，在ubuntu下用它自带的软件中心安装了eclipse（不清楚啥版本），JDK使用的是1.8.0版。目前能够在eclipse中看到mapreduce插件，但是将hadoop0.20.2自带的测试程序WordCount做测试时，报错（而且是第一行）：
Description Resource Path Location Type The type java.util.Map$Entry cannot be resolved. It is indirectly referenced from required .class files WordCount.java
The project was not built since its build path is incomplete. Cannot find the class file for java.util.Map$Entry. Fix the build path then try building this project WordCount
------解决方案--------------------
换成jdk1.6 就好了！我的问题得到了解决！
