Hi,
1 - I would like to know if a Map Task can produce more than 1 map output per execution? 2 - A Map Task can't be reused, right? When a Map Task instance produced a map outputs, this instance will end, right? 3 - I would like to know if a ReduceCopier will fetch only 1 map output at a time and saves it in a file or in memory before merging them? For example, if we've a ReduceCopier that fetches 4 map outputs, the reduce will save the 4 outputs in separate and only after all map outputs are copied to the reduce side, that the ReduceCopier will merge them, right? Thanks, -- Pedro
