注意这个帖子和
原因：java.lang.classnotfoundexception:类路径
但不同的错误信息。
当我试着从https://cwiki.apache.org/confluence/display/mahout/wikipedia+bayes+example
当我运行以下命令时：

lis-macbook-pro:mahout-distribution-0.8 Li$ mahout wikipediaXMLSplitter -d examples/temp/enwiki-latest-pages-articles10.xml -o wikipedia/chunks -c 64

我收到错误信息：

我正在使用hadoop1.2和mahout 0.8。mahout-distribution-0.8/bin已添加到$path$mahout\u local设置为“true”，因此它在本地运行。
我不知道为什么会出现“无法添加类：wikipediaxmlsplitter”
