How to pull data in the Map/Reduce functions?

[Praveen Sripati]

Hi,

Normally the Hadoop framework calls the map()/reduce() for each record in
the input split. I read in the 'Hadoop : The Definitive Guide' that that
data can be pulled using the new MR API.

What is the new API for pulling the data in the map()/reduce() or is there a
sample code?

Thanks,
Praveen
