Thanks lot it works .
By using this code
SequenceFile.Reader reader = new SequenceFile.Reader(fs,path1, conf);
IntWritable key = new IntWritable();
WeightedVectorWritable value = new WeightedVectorWritable();
while (reader.next(key, value))
{
System.out.println(value.toString() + " belongs to cluster "+
key.toString());
}
reader.close();
i got the which documents
Can you help how to get the files from the documents id
Thanks and Regards,
