Description

I have written a Map only job and have set MapOutput(Key|Value)Class.
Job was passing when I set TextOutputFormat, however, when I changed the OF to SequenceFileOutputFormat, job started failing.

Later, I have set them to Output(Key|Value)Class, and job was passing.

I think, for Map only jobs, jobs should pass even for MapOutput(Key|Value)Class.
