Dear Harsh,
thanks for your answer. Your post talks about the intermediate and final
result types.
These are already configured in my job as:
job.setOutputKeyClass(IntWritable.class);
job.setOutputValueClass(IntWritable.class);
My problem was input key and value types, though.
Your post let me look in the right direction. I added
job.setInputFormatClass(SequenceFileInputFormat.class);
which did the trick.I thought this would be done by the
SequenceFileAsBinaryInputFormat.addInputPath(jobConf, new
Path(args[i]));
Best regards,
Jens
