我正在尝试在 hadoop 2.0 中读取一个序列文件，但我无法实现它。我正在使用以下代码，它在 hadoop 1.0 中运行良好。如果我遗漏了 2.0 版的内容，请告诉我
Configuration conf = new Configuration();
try {
FileSystem fs = FileSystem.get(conf);
Path p = new Path("/Users/xxx/git/xxx/src/test/cntr-20140527104344-r-00172");
SequenceFile.Reader reader = new SequenceFile.Reader(fs,p,conf);
Writable key = (Writable) ReflectionUtils.newInstance(reader.getKeyClass(), conf);
Writable value = (Writable) ReflectionUtils.newInstance(reader.getValueClass(), conf);
我在尝试调试时收到以下错误。

请帮忙。
注意：使用 Hadoop 2.0 API 读写序列文件 我参考了这个链接。但它没有用。
