To generate a single output file, specify just a single reduce task. If your reducer isn't doing much computation, then it might be faster to do this in the original job, otherwise use a subsequent job.

This is probably a simple question but when I run my MR job I am getting 10 splits and therefore 10 output files like part-xxxxx. Is there a way to merge those outputs into a single file using the currently running MR job or do I need to run another MR job to merge them?
