try and checkout the build file and see where he takes the files when he builds the job file. When you run nutch in hadoop it's not going to use config files in the NUTCH_CONF_DIR but those in the job file. So you should forget about NUTCH_CONF_DIR at run time, but to properly build 2 job files, one with one set of configuration files and one with the other one.
