All, I have a job where there I need to have but a single reducer.
i.e. job.setNumReduceTasks(1); When I do this, I get no log file for the reducer; mappers yes, but reducer no. If I remove the aforementioned statement, hadoop will spawn the appropriate number of reducers as per my configuration and log file output will ensue. Does anyone know anything about this? Thanks. -- Geoffry Roberts
