Jeff, Hadoop (HDFS in particular) is overly strict about machine names. The filesystem's id is based on the DNS name used to access it. This needs to be consistent across all nodes and all configurations in your cluster. You should always use the fully-qualified domain name of the namenode in your configuration.
