我从 cloudera 下载并设置了 hadoop-cdh3u2。在 hadoop-0.20.2-cdh3u2/src/contrib 我找到了一个名为“eclipse-plugin”的项目，我在 eclipse 中导入了它，得到了错误，并添加了 hadoop-core.jar 作为 eclipse 应用程序运行，但我不能添加一个新服务器（我是否需要更新“MANIFEST.MF”中的任何内容）？？。我收到以下错误。我想知道将这个项目导出到 jar 中是正常过程，还是我需要做任何额外的事情？？？

eclipse版本为indigo，平台Ubuntu 11.10，java版本为1.6

Surendhar，Eclipse 插件不适用于 hadoop 0.20.203。* 在这里查看：https ://issues.apache.org/jira/browse/HADOOP-7382
