For starters look at any monitoring tool like vaidya, hadoop UI ( ganglia too, haven't read much on it though ). Not sure if you need this for debugging purposes or for some other real-time app.. You should be able to get info on localhost of each of your map tasks in a pretty straightforward way using Java Inetaddress APIs( and use that info for search?)
