安装插件，配置好连接之后 ，点击大象图标，eclipse连不上DFS。通过Error-log分析出错原因是缺少jar包。解决方法是将commons-httpclient-3.0.1.jar,jackson-core-asl-1.0.1.jar,jackson-mapper-asl-1.0.1.jar,commons-configuration-1.6.jar,lcommons-lang-2.4.jar放入hadoop-0.20.203.0-eclipse-plugin的lib下
修改hadoop-0.20.203.0-eclipse-plugin/META-INF/MANIFEST.MF
Bundle-ClassPath: classes/,lib/hadoop-core.jar,lib/commons-cli-1.2.jar,lib/commons-httpclient-3.0.1.jar,lib/jackson-core-asl-1.0.1.jar,lib/jackson-mapper-asl-1.0.1.jar,lib/commons-configuration-1.6.jar,lib/commons-lang-2.4.jar
