    The output brianwc using Hadoop is not a file, instead it's a directory. Could u give some explanations?

    brianwc is a directory if you're using HDFS, and is a file if you're using the local filesystem. The reason it's a directory in the former case is because multiple result files go in there, one per reducer.
