Maybe try downloading the Apache Commons - Logging jars (< http://commons.apache.org/downloads/download_logging.cgi>) and drop them in to $HADOOP_HOME/lib. Just curious, if you're starting a new cluster, why have you chosen to use 0.17.* and not 0.18.2? It would be a good idea to use 0.18.2 if possible.
