Hi Wayne, For the error message you're receiving – you will need to copy the Hadoop jar files from the Hadoop cluster you're trying to connect to. A couple good references on that call out include: Configuring Eclipse for Hadoop Development (a screencast …<http://www.google.com/url?sa=t&rct=j&q=setup%20eclipse%20for%20hadoop&source=web&cd=1&ved=0CFoQFjAA&url=http%3A%2F%2Fwww.cloudera.com%2Fblog%2F2009%2F04%2Fconfiguring-eclipse-for-hadoop-development-a-screencast%2F&ei=rP6oT_uJK6OriAKL1bCyAg&usg=AFQjCNFSn9WUJRda4w6assu3NBdaZXOf3g&sig2=5q0pujY-WQyh7V77qJUsnQ> Hadoop Tutorial – YDN<http://www.google.com/url?sa=t&rct=j&q=setup%20eclipse%20for%20hadoop&source=web&cd=2&ved=0CFsQFjAB&url=http%3A%2F%2Fdeveloper.yahoo.com%2Fhadoop%2Ftutorial%2Fmodule3.html&ei=rP6oT_uJK6OriAKL1bCyAg&usg=AFQjCNH4LIKdAY3IxTnqV5uguF0HyYFZmg&sig2=ywIgtV6bIKiRxnWfhKMVxA>

I’m following the “Working with Hadoop under Eclipse” wiki to do this. First let me make sure this will do what I am hoping it will do. I’m not so much interested in modifying the Hadoop code itself (although I may in the not too distant future). I’m more looking to be able to code and test mappers and reducers in Eclipse and leverage the debugging and other tools in Eclipse in that process. If that’s not what the wiki is describing than let me know that and ignore my issue. If there is a way to do this, would you please point me to where I can find the instructions. If this is what the wiki is describing than I have an issue I need help with. I’ve followed the directions on the Wiki and even worked through a couple of issues by searching the archive. However, now I’ve hit an error that while I did find it in the archive, the fix that was presented is not fixing my issue. After importing all the projects, I get a build error: “Project ‘MapReduceTools’ is missing required library: ‘lib/hadoop-core.jar’”. I’ve added the M2_REPO variable as someone suggested in the archive where I found this error once. That hasn’t fixed or even changed the error. I’ve looked in my maven repository (c:\Users\wwilso\.m2\repository) and there is not a “Hadoop-core.jar” anywhere in the repository that windows explorer can find. In fact, windows explorer can’t find a “Hadoop-core.jar” anywhere on my c:\ drive. I did my build using the directions from the wiki (got source using git in cygwin and then executing the two maven commands in cywgin). I did use the patch for the “scripts/saveVersion.sh” not found error to resolve that issue. That’s the only thing I have changed from the wiki or code. Using Maven-3.0.4, ant-1.8.3, and protobuf-2.4.1. Anyone have any ideas? Thanks in advance.
