Hello,
I was wondering - could someone tell me what are the reasons that I could
get failure with certain map tasks on a node?
Well, that depends on the kind of errors you are seeing. Could you plz
post the logs/error messages?

Any idea that comes to mind
would work (it does not happen because my program aborts).
Also, what could cause with hadoop for a map task to take longer (although
data is the same for all maps) to finish than the other tasks?
What Hadoop version are you using? What is the average runtime of the
maps? How much difference are you seeing? Are all the nodes same in
terms of config?
Thanks
