根據mahout in action中的14.6章節做的測試，記錄如下：
1：將20news-bydate-train和20news-bydata-test中的每個目錄中的數據轉換爲以目錄名稱開始的包含所有單詞的簡單文本文件，使用的mahout命令如下：
mahout prepare20newsgroups -p 20news-bydate-train/ -o 20news-train/ -a org.apache.lucene.analysis.atandard.StandardAnalyzer -c UTF-8
mahout prepare20newsgroups -p 20news-bydate-test/ -o 20news-test/ -a org.apache.lucene.analysis.standard.StandardAnalyzer -c UTF-8
2:啓動集羣
start-all.sh
3：將第一步中生成的20news-train目錄拷貝到hdfs中。
hadoop fs -put 20news-train /user/root/
4：通過naive Bayes算法訓練樣本生成20news-model，命令及運行過程如下：
mahout trainclassifier -i 20news-train -o 20news-model -type cbays -ng 1 -source hdfs
