So, maps completed?  Are you using TableReduce? Maybe you need to 
instrument this?  Where is your job hung up?  When it fails, what task 
does it report as the problem one?  If you look at the task log, any 
clues?  Does it say timed out because failed report to TaskTracker?  Was 
it a map or a reduce task?
