how to read custom writable object from hdfs use java api?

I have map-reduce job to output my custom writable objects, how can I
read it using pure java api?
I don't want to serialize it to string(Text) and deserialize using java.

map reduce codes..

job.setOutputKeyClass(IntWritable.class);
job.setOutputValueClass(MyWritable.class);
