我想在有两个节点的freebsd集群上运行mapreduce作业，但出现以下异常

当我试着跑的时候就会这样 job.watForCompletion(true); 在一个新的mapreduce工作。应该抛出nosuchelementexception，因为stringtokenizer和next（）中没有更多元素被调用。我查看了源代码，在rawlocalfilesystem.java中发现了以下代码部分：

/// loads permissions, owner, and group from `ls -ld`
private void loadPermissionInfo() {
  IOException e = null;
  try {
    String output = FileUtil.execCommand(new File(getPath().toUri()), 
        Shell.getGetPermissionCommand());
    StringTokenizer t =
        new StringTokenizer(output, Shell.TOKEN_SEPARATOR_REGEX);
    //expected format
    //-rw-------    1 username groupname ...
    String permission = t.nextToken();

据我所知，hadoop试图找到一个特定文件的一些权限 ls -ld 如果我在控制台中使用它，效果会很好。不幸的是，我还没有发现，它正在寻找哪些文件权限。
hadoop版本是2.4.1，hbase版本是0.98.4，我使用的是javaapi。其他操作，如创建一个表，工作得很好。有没有人遇到过类似的问题或知道该怎么办？
编辑：我刚刚发现这只是一个与hadoop相关的问题。即使不使用hdfs，也要进行最简单的mapreduce操作，这给了我同样的例外。
