stages. Copy-> sort-> reduce. Each map of a job divides the data into map output results and N partitions Based on the reduce (n) number, therefore, the intermediate result of map may contain part of the data to be processed by each reduce. Therefore, in order to optimize the reduce execution time, hadoop is waiting for the end of the first map of the job, all reduce workers start to try to download part of the partition data corresponding to the reduce from the completed map. This process is g
