             Summary: Map only jobs should work even for MapOutput(Key|Value)Class configuration
                 Key: MAPREDUCE-4389
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4389
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: job submission, mrv2
    Affects Versions: 2.0.0-alpha, trunk
            Reporter: Bhallamudi Venkata Siva Kamesh
            Assignee: Bhallamudi Venkata Siva Kamesh


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.
