Hadoop 0.20.2 Eclipse插件不能完全运行 - 不能'Hadoop运行' [英] Hadoop 0.20.2 Eclipse plugin not fully functioning - can't 'Run on Hadoop'

问题描述

我刚刚在Windows 7上使用Eclipse Helios（3.6）在Cygwin下安装Hadoop 0.20.2。 Hadoop现在完全启动，我试图在Eclipse中新创建的MapReduce测试项目中运行测试应用程序。我正在使用Hadoop下载中的Hadoop 0.20.2插件。

I've just finished installing Hadoop 0.20.2 under Cygwin on Windows 7 with Eclipse Helios (3.6). Hadoop is now fully started, and I'm trying to run a test application within a newly created MapReduce test project in Eclipse. I'm using the Hadoop 0.20.2 plugin from the Hadoop download.

映射/减少位置透视图正确运行，软件包资源管理器中的DFS位置树。但是，当我右键单击驱动程序，选择运行为>在Hadoop上运行，没有任何反应，没有错误产生在控制台上（静默失败:(））我相信一个对话框窗口应该出现，

The Map/Reduce Location perspective operates correctly, as does DFS Locations tree in the Package Explorer. However, when I right-click the driver, select 'Run As' > 'Run on Hadoop', nothing happens and no errors spawn on the Console (silent fail :(). I believe a dialog window should appear asking for config before it runs, but this is not happening.

似乎有一些其他人有同样的问题，但我还没有找到一个有效的答案。尝试了0.20.1插件（总失败）下面的错误报告似乎描述我的问题，虽然我有点新手所有这一切，所以可以做一个手/声音的经验帮助： https://issues.apache.org/jira/browse/MAPREDUCE-1280 p>

There seems to be a few others with the same problem, but I've yet to find an answer that works. I've tried the 0.20.1 plugin (total fail). The following bug report seems to describe my issue, though I'm a bit of a newbie to all this, so could do with a hand / voice of experience to help out: https://issues.apache.org/jira/browse/MAPREDUCE-1280

只需从Eclipse安装中删除旧的插件，并将新版本的插件放入eclipse安装的dropins-folder。

Simply remove the old plugin from your eclipse-installation and put the new version of the plugin into the dropins-folder of your eclipse-installation.

从旧版本的插件升级后，您必须使用-clean命令行开关启动eclipse。有关eclipse命令行开关的帮助，请访问此处。

After upgrading from an older version of the plugin you will have to start eclipse with the "-clean" command line switch. Help on eclipse command line switches can be found here.
