Subject Re: counter for number of mapper records

Yes, take a look at
src/mapred/org/apache/hadoop/mapred/Task_Counter.properties

Those are all the counters available for a task.

Subject: counter for number of mapper records

If I understand correctly, each mapper is sent a set number of records. Is
there a counter or variable that tells you how many records is sent to a
particular mapper?
Likewise, is there a similar thing for reducers?

Thanks in advance.
