Hi there, Does the map input (for a certain node) on the DFS get copied to the local FS before work starts on it? Can you point me to a place in the code for this?
Plus once the shuffle phase ends and the reduce task receives all the intermediate data from all the maps, does every reduce copies the intermediate data to the DFS for safe keeping? thanks for all the help :) regards, -- Ahmad Humayun Research Assistant Computer Science Dpt., LUMS +92 321 4457315
