      Description

      TEZ-2162 didn't resolve it completely. Paste the comment from TEZ-2162

      But there's one exceptional case that if user specify OutputFormat through conf, then even MROutput is on mapper side, user still need to use property MRJobConfig.NEW_API_REDUCER_CONFIG rather than NEW_API_MAPPER_CONFIG. Or I think we can take useNewAPI as true as any of NEW_API_MAPPER_CONFIG, NEW_API_REDUCER_CONFIG is set true (patch didn't include this now)

      This issue happens when translating from Mapper-only MR job to tez.
