我正在嘗試NaiveBayesClassifer使用hadoop 運(yùn)行一個(gè)簡單的程序，出現(xiàn)此錯(cuò)誤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$200(FileSystem.java:66) at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:1390) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:196) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:95) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:180) at org.apache.hadoop.fs.Path.getFileSystem(Path.java:175) at org.apache.mahout.classifier.naivebayes.NaiveBayesModel.materialize(NaiveBayesModel.java:100)代碼： Configuration configuration = new Configuration(); NaiveBayesModel model = NaiveBayesModel.materialize(new Path(modelPath), configuration);// error in this line..modelPath指向NaiveBayes.bin文件，并且配置對(duì)象正在打印-Configuration: core-default.xml, core-site.xml我認(rèn)為是因?yàn)楣拮樱惺裁聪敕▎幔?

對(duì)于使用shade插件的用戶，按照david_p的建議，您可以通過將ServicesResourceTransformer添加到插件配置中來合并陰影jar中的服務(wù)：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
這會(huì)將所有org.apache.hadoop.fs.FileSystem服務(wù)合并到一個(gè)文件中
