Hello All, 
I'm learning hadoop, hdfs etc and currently tying to solve one issue. Can someone help me how to start attacking the following problem:

I'm trying to come up with some sample code  to store the files  \YEAR\Month\Date\account structure using Hadoop technique s.

Example: The file will submit to the program as below
Test_20120917_ACC1.csv and Test_20120916_ACC2.csv

HDFS has to create structure as below


Can someone give me pointers on how to start on this. Highly Appreciated. Thanks for reading the question.
