Hi Cheolsoo,
Thanks - I will try this now and get back to you.
Out of interest; could you explain (or point me towards resources that
would) why the combiner would be a problem?
Also, could the fact that Pig builds an intermediary data structure (?)
whilst Hive just performs a sort then the

Hi Benjamin,
To answer your question, how the Hadoop combiner works is that 1) mappers

again. So you're paying extra disk I/O as well as
serialization/deserialization.
This will pay off if combiners significantly reduce the

Package
When data comes out of a map task, Hadoop serializes it so that it can know its
exact size as it writes it into the output buffer. To run it through the
combiner it needs to deserialize it again, and then re-serialize it when it
comes out. So each pass through the combiner costs a
