Hi, The Eclipse plugin communicates directly with the RPC servers of NN, DNs, and JT. It does not, in any way, use SSH to do this.
If your machine can't setup a fully functional connection to the cluster, then the Eclipse plugin will currently not work and you have to fall back into doing the manual compile-jar -> scp -> invoke cycle, or rely on a local MR cluster (pseudo-distributed) or the local job runner (standalone) to test your programs. There is a proposal for splitting out the Eclipse plugin code to its own project, at http://wiki.apache.org/incubator/HadoopDevelopmentToolsProposal, and adding further enhancements to it. Perhaps when this project is setup, you can request for such a feature where the plugin may itself automate the jar production plus scp and invoke it at the other end - for such scenarios.
