My data is in the format of csv file (sam,1,34,there,hello). I want to add an image to each row in the csv file using hadoop. Does any body have any idea about it. I have seen about Hipi which process the image files and adds it also. But I want to add as a column to csv file.

If you have to use CSV file, consider using Base64 encoding over binary image data - it will give you a printable string. But in general I would recommend you to switch to sequence file, there you would be able to store the image directly in a binary format
