Map Recude code doubt
Hello All, I was wondering if our map reduce code can just return the location of the file? Or place the actual file in a given output directory by searching based on a keyword. Let me make myself clear If there are 100 image files in my HDFS and I want to extract one image file. If I give a keyword which matches the name of a file in my HDFS will my mapper and reducer code be able to locate that file and put back the original file in a given location?? Please let me know if you have need more information.

Shwitzu, Why can't you just use query thru a Filesystem object and find the file you want?
