Subject Question regarding reduce tasks
Date Mon, 03 Nov 2008 16:15:02 GMT

Is it safe to assume that only one reduce task will ever operate on
values for a particular key? Or is it possible that more than one
reduce task can work on values for the same key? The reason I ask is
because I want to ensure that a piece of code that I write at the end
of my reducer method will only ever be executed once after all values
for a particular key are aggregated/summed.
