Hello, In a mapreduce job, a given map JVM will run N map tasks. Are the configure and close methods executed for every one of these N tasks? Or is configure executed once when the JVM starts and the close method executed once when all N have been completed?
I have the same question for the reduce task. Will it be run before for every reduce task? And close is run when all the values for a given key have been processed? We can assume there isn't a combiner. Regards Saptarshi
