我试图运行一个简单的NaiveBayesClassifer使用hadoop,得到这个错误
Exception in thread "main" java.io.IOException: No FileSystem for scheme: file
at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:1375)
at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:66)

at org.apache.hadoop.fs.Path.getFileSystem(Path.java:175)
at org.apache.mahout.classifier.naivebayes.NaiveBayesModel.materialize(NaiveBayesModel.java:100)
代码:
Configuration configuration = new Configuration();
NaiveBayesModel model = NaiveBayesModel.materialize(new Path(modelPath), configuration);// error in this line..
modelPath指向NaiveBayes.bin文件,配置对象正在打印 -Configuration: core-default.xml, core-site.xml
我认为这是因为罐子,任何想法？
