-----------------------------------------
Arun,
Can you elaborate on the difference between "user" and "system" errors? I can
imagine IOException getting thrown from within Hadoop internals just as much as
from within a user's map() method. The distinction you mentioned above seems
somewhat arbitrary to me at first glance.
