Explicit Data Placement on Hadoop

Dear all, 

I understand that specifying data placement may not be in the spirit of
Hadoop, however I would like to explicitly locate data input on various
nodes to assert the value of data locality and cost of network transfer. 

Does anyone have any advice about how I can go about the data placement? 

Thanks, 

Yipeng
