Hi, This was very helpful to me : http://www.cloudera.com/blog/2009/04/20/configuring-eclipse-for-hadoop-development-a-screencast/
I have similar set up as yours and got through without any issues. Amogh On 11/3/09 11:58 PM, "smarthr...@yahoo.co.in" <smarthr...@yahoo.co.in> wrote: Hi . I am trying to work on building Hadoop in Eclipse. The version I am checking out is http://svn.apache.org/repos/asf/hadoop/common/tags/release-0.20.1 . After checking out this release and following the instructions on the http://wiki.apache.org/hadoop/EclipseEnvironment page I am still not able to build this release. After running the build.xml I get a message saying Build Successful but in the Problems tab it shows errors like : Description Resource Path Location Type Counters cannot be resolved to a type
