我正在尝试使用“hadoop-jar”运行一个jar（maven项目），结果得到错误“no filesystem for scheme”。我在stackoverflow上读到了这个错误，似乎问题出在meta-inf/services/org.apache.hadoop.fs.filesystem中。我的看起来像这样：

org.apache.hadoop.fs.LocalFileSystem
org.apache.hadoop.fs.viewfs.ViewFileSystem
org.apache.hadoop.fs.ftp.FTPFileSystem
org.apache.hadoop.fs.HarFileSystem

hdfs行丢失。这是我代码的一部分：

public int run(String[] args) throws Exception {   
     Configuration conf=getConf();    conf.set("fs.hdfs.impl",org.apache.hadoop.hdfs.DistributedFileSystem.class.getName());       conf.set("fs.file.impl",org.apache.hadoop.fs.LocalFileSystem.class.getName()); 
       args = new GenericOptionsParser(conf, args).getRemainingArgs();       
     Job job = Job.getInstance(conf,"Count");
     job.setInputFormatClass(ImageBundleInputFormat.class);
     job.setMapperClass(CountMapper.class);
     job.setReducerClass(CountReducer.class);
     job.setMapOutputKeyClass(IntWritable.class);
     job.setMapOutputValueClass(IntWritable.class);
     job.setOutputKeyClass(IntWritable.class);
     job.setOutputValueClass(Text.class);
     FileInputFormat.setInputPaths(job, new Path(args[0]));
     FileOutputFormat.setOutputPath(job, new Path(args[1]));
     job.addCacheFile(new URI("//path/lbpcascade_frontalcatface.xml"));
     job.setJarByClass(Count.class);
     boolean success = job.waitForCompletion(true);
     return success ? 0 : 1;
   }

public static void main(String[] args) throws Exception {

       ToolRunner.run(new Count(), args);
       System.exit(0);
   }

错误位于boolean success=job.waitforcompletion（true）行；任何帮助都将不胜感激。谢谢！：）
