So, you're say that hadoop assumes there is a specific directory hierarchy on HDFS? Namely that there exists a top-level directory /user/ and that there exist various username directories under /user/?
I only ask because I've never bothered to configure an HDFS system that specific way? I didn't think there was any reason to impose such a directory hierarchy, but if hadoop really builds implicit paths on such an assumption then that is a good reason to be somewhat strict about organizing files on HDFS in a corresponding fashion.
