I wouldn't suggest using append yet. If you really just want side-
effects from a job, you can use the NullOutputFormat that just ignores
the output and throws it away.
If you want it to come back out to the launching program, you could
just print it to stderr in the task and set
JobClient.setTaskOutputFilter to SUCCEEDED and the output will be
printed. (Don't try this at home on a real cluster, or your client
will be swamped!)
