Hi, If all you want to do is to write programs that use your stable hadoop libraries, have a look at the Hadoop Eclipse plugin that comes along (inside contrib folders).
If you want your stable hadoop as a project inside your eclipse itself, run `ant eclipse` in the hadoop's extracted directory (or was it eclipse-files?) and then import the folder using the 'Existing Projects into Workspace' import option. Alternatively, for the former requirement, you may use KarmaSphere's Hadoop eclipse plugin (the free Community Edition). It's a great tool to use as well. Both the Apache-suppled plugin and the KarmaSphere plugin allows you to run your MR code instantly onto a supplied cluster. And then some. P.s. You might need to patch the existing apache-supplied hadoop eclipse plugin a bit to make it usable on the latest versions of Eclipse.
