Subject Question About Using a Single Reducer
Date Fri, 20 May 2011 16:18:19 GMT

I have a job where there I need to have but a single reducer.


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?
