摘要
A data processing control device performs a MapReduce process. When the data processing control device assigns input data to first Reduce tasks and a second Reduce task performed by using a result of Map processes, the data processing control device assigns input data with smaller amount than any of amounts of the input data which is assigned to the first Reduce tasks to the second Reduce task. The data processing control device assigns the first Reduce tasks and the second Reduce task, to which input data is assigned, to a server that performs Reduce processes in the MapReduce process such that the second Reduce task is started after the assignment of all of the first Reduce tasks.
