title: Files not put correctly into distributed cache
body: <p>I am adding a file to distributed cache using the following code: </p>
  
  <pre><code>Configuration conf2 = new Configuration();      
  job = new Job(conf2);
  job.setJobName("Join with Cache");
  DistributedCache.addCacheFile(new URI("hdfs://server:port/FilePath/part-r-00000"), conf2);
  </code></pre>
  
  <p>Then I read the file into the mappers:</p>
  
  <pre><code>protected void setup(Context context)throws IOException,InterruptedException{
  Configuration conf = context.getConfiguration();
  
  URI[] cacheFile = DistributedCache.getCacheFiles(conf);
  FSDataInputStream in = FileSystem.get(conf).open(new Path(cacheFile[0].getPath()));
  BufferedReader joinReader = new BufferedReader(new InputStreamReader(in));
  
  String line;
          try {
                while ((line = joinReader.readLine()) != null) {
                s = line.toString().split("\t");
                    do stuff to s
                  } finally {
                     joinReader.close();
                  }
  </code></pre>
  
  <p>The problem is that I only read in one line, and it is not the file I was putting into the cache.  Rather it is: cm9vdA==, or root in base64.</p>
  
  <p>Has anyone else had this problem, or see how I'm using distributed cache incorrectly?  I am using Hadoop 0.20.2 fully distributed.</p>
