Subject Re: Setup Hadoop for Eclipse
Date Fri, 25 Mar 2011 11:50:44 GMT
Does anyone have a working configuration in Eclipse for hadoop checked out as separate projects
from SVN (as described under http://wiki.apache.org/hadoop/EclipseEnvironment)?

I'm probably missing something simple here, so knowing that others made it work would help!

Thanks
David
