Computation task adjusting method and device

The embodiment of the invention provides a computation task adjusting method and device. The method comprises the following steps: determining a target node corresponding to a target computation task; acquiring target parameter information corresponding to the target node; computing total target time consumption of the target node performing computation on the target computation task according to the target parameter information; and adjusting the target computation task according to the total target time consumption and the total time consumption corresponding to other computation tasks excepting the target computation task and based on the time consumption balance principle. According to the method, the influence factor in computation task computation processing of each node is considered, and each computation task is adjusted, so that the difference of time for each node computing the corresponding computation task is reduced, and as a result, the efficiency of MapReduce computing the whole file can be inc
