Embodiment Construction
[0035] Introduced below are some of the various embodiments of the invention, intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of protection.
[0036] A distributed job is usually divided into two types of tasks: slice parallel task (map) and merge reduction task (reduce). Each type of task will have several identical subtasks. Subtasks of the same type usually have the same input data split size (split). For example, most of the multi-cluster distributed jobs now use the Hadoop framework. In the Hadoop framework, distributed tasks are divided into two stages, the map stage and the reduce stage. Therefore, there are correspondingly two types of subtasks, the map subtask (sharding the data) and the reduce subtask (reducing the sliced data), and the reduce phase can only be entered after the map phase is completed. The input data slice size of the same type of subtas...
