I am trying to read a sequencefile in hadoop 2.0 but I am unable to achieve it. I am using the below code which works perfectly fine in hadoop 1.0. Please let me know if I am missing something wrt 2.0
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);
I am getting the below error while trying to debug.

Kindly help.
Note : Reading and Writing Sequencefile using Hadoop 2.0 Apis I referred this link. But it did not work.
