Subject Working of combiner in hadoop
Date Fri, 04 Jul 2014 05:29:09 GMT
Hi,

If have two map tasks running on one node , i have written combiner class also.
Will combiner be called once for each map task or just once for both the map tasks

Can i write a logic inside map which will work as combiner ? if yes will there be any side
effect?

Regards,
Chhaya Vishwakarma
